-# Charon Instructions
-
-## Code Quality Guidelines
-
-Every session should improve the codebase, not just add to it. Actively refactor code you encounter, even outside of your immediate task scope. Think about long-term maintainability and consistency. Make a detailed plan before writing code. Always create unit tests for new code coverage.
-
-- **DRY**: Consolidate duplicate patterns into reusable functions, types, or components after the second occurrence.
-- **CLEAN**: Delete dead code immediately. Remove unused imports, variables, functions, types, commented code, and console logs.
-- **LEVERAGE**: Use battle-tested packages over custom implementations.
-- **READABLE**: Maintain comments and clear naming for complex logic. Favor clarity over cleverness.
-- **CONVENTIONAL COMMITS**: Write commit messages using `feat:`, `fix:`, `chore:`, `refactor:`, or `docs:` prefixes.
-
-## 🚨 CRITICAL ARCHITECTURE RULES 🚨
-
-- **Single Frontend Source**: All frontend code MUST reside in `frontend/`. NEVER create `backend/frontend/` or any other nested frontend directory.
-- **Single Backend Source**: All backend code MUST reside in `backend/`.
-- **No Python**: This is a Go (Backend) + React/TypeScript (Frontend) project. Do not introduce Python scripts or requirements.
-
-## Big Picture
-
-- Charon is a self-hosted web app for managing reverse proxy host configurations with the novice user in mind. Everything should prioritize simplicity, usability, reliability, and security, all rolled into one simple binary + static assets deployment. No external dependencies.
-- Users should feel like they have enterprise-level security and features with zero effort.
-- `backend/cmd/api` loads config, opens SQLite, then hands off to `internal/server`.
-- `internal/config` respects `CHARON_ENV`, `CHARON_HTTP_PORT`, `CHARON_DB_PATH` and creates the `data/` directory.
-- `internal/server` mounts the built React app (via `attachFrontend`) whenever `frontend/dist` exists.
-- Persistent types live in `internal/models`; GORM auto-migrates them.
-
-## Backend Workflow
-
-- **Run**: `cd backend && go run ./cmd/api`.
-- **Test**: `go test ./...`.
-- **API Response**: Handlers return structured errors using `gin.H{"error": "message"}`.
-- **JSON Tags**: All struct fields exposed to the frontend MUST have explicit `json:"snake_case"` tags.
-- **IDs**: UUIDs (`github.com/google/uuid`) are generated server-side; clients never send numeric IDs.
-- **Security**: Sanitize all file paths using `filepath.Clean`. Use `fmt.Errorf("context: %w", err)` for error wrapping.
-- **Graceful Shutdown**: Long-running work must respect `server.Run(ctx)`.
-
-## Frontend Workflow
-
-- **Location**: Always work within `frontend/`.
-- **Stack**: React 18 + Vite + TypeScript + TanStack Query (React Query).
-- **State Management**: Use `src/hooks/use*.ts` wrapping React Query.
-- **API Layer**: Create typed API clients in `src/api/*.ts` that wrap `client.ts`.
-- **Forms**: Use local `useState` for form fields, submit via `useMutation`, then `invalidateQueries` on success.
-
-## Cross-Cutting Notes
-
-- **VS Code Integration**: If you introduce new repetitive CLI actions (e.g., scans, builds, scripts), register them in .vscode/tasks.json to allow for easy manual verification.
-- **Sync**: React Query expects the exact JSON produced by GORM tags (snake_case). Keep API and UI field names aligned.
-- **Migrations**: When adding models, update `internal/models` AND `internal/api/routes/routes.go` (AutoMigrate).
-- **Testing**: All new code MUST include accompanying unit tests.
-- **Ignore Files**: Always check `.gitignore`, `.dockerignore`, and `.codecov.yml` when adding new file or folders.
-
-## Documentation
-
-- **Features**: Update `docs/features.md` when adding capabilities.
-- **Links**: Use GitHub Pages URLs (`https://wikid82.github.io/charon/`) for docs and GitHub blob links for repo files.
-
-## CI/CD & Commit Conventions
-
-- **Triggers**: Use `feat:`, `fix:`, or `perf:` to trigger Docker builds. `chore:` skips builds.
-- **Beta**: `feature/beta-release` always builds.
-
-## ✅ Task Completion Protocol (Definition of Done)
-
-Before marking an implementation task as complete, perform the following:
-
-1. **Pre-Commit Triage**: Run `pre-commit run --all-files`.
-    - If errors occur, **fix them immediately**.
-    - If logic errors occur, analyze and propose a fix.
-    - Do not output code that violates pre-commit standards.
-2. **Verify Build**: Ensure the backend compiles and the frontend builds without errors.
-3. **Clean Up**: Ensure no debug print statements or commented-out blocks remain.

-- **Project**: Charon (Self-hosted Reverse Proxy)
-- **Stack**: Go 1.22+, Gin, GORM, SQLite.
-- **Rules**: You MUST follow `.github/copilot-instructions.md` explicitly.

-
-<workflow>
-1.  **Initialize**:
-    -   **Path Verification**: Before editing ANY file, run `list_dir` or `search` to confirm it exists. Do not rely on your memory.
-    -   Read `.github/copilot-instructions.md` to load coding standards.
-    -   **Context Acquisition**: Scan chat history for "### 🤝 Handoff Contract".
-    -   **CRITICAL**: If found, treat that JSON as the **Immutable Truth**. Do not rename fields.
-    -   **Targeted Reading**: List `internal/models` and `internal/api/routes`, but **only read the specific files** relevant to this task. Do not read the entire directory.
-
-2. **Implementation (TDD - Strict Red/Green)**:
-    - **Step 1 (The Contract Test)**:
-        - Create the file `internal/api/handlers/your_handler_test.go` FIRST.
-        - Write a test case that asserts the **Handoff Contract** (JSON structure).
-        - **Run the test**: It MUST fail (compilation error or logic fail). Output "Test Failed as Expected".
-    - **Step 2 (The Interface)**:
-        - Define the structs in `internal/models` to fix compilation errors.
-    - **Step 3 (The Logic)**:
-        - Implement the handler in `internal/api/handlers`.
-    - **Step 4 (The Green Light)**:
-        - Run `go test ./...`.
-        - **CRITICAL**: If it fails, fix the *Code*, NOT the *Test* (unless the test was wrong about the contract).
-
-3. **Verification (Definition of Done)**:
-    - Run `go mod tidy`.
-    - Run `go fmt ./...`.
-    - Run `go test ./...` to ensure no regressions.
-    - **Coverage**: Run the coverage script.
-        - *Note*: If you are in the `backend/` directory, the script is likely at `/projects/Charon/scripts/go-test-coverage.sh`. Verify location before running.
-    - Ensure coverage goals are met as well as all tests pass. Just because Tests pass does not mean you are done. Goal Coverage Needs to be met even if the tests to get us there are outside the scope of your task. At this point, your task is to maintain coverage goal and all tests pass because we cannot commit changes if they fail.

-    - **Contract Enforcement**: Does the code actually match the JSON Contract defined in the Spec?
-
-3. **Execute**:
-    - **Path Verification**: Run `list_dir internal/api` to verify where tests should go.
-    - **Creation**: Write a new test file (e.g., `internal/api/tests/audit_test.go`) to test the *flow*.
-    - **Run**: Execute `go test ./internal/api/tests/...` (or specific path). Run local CodeQL and Trivy scans (they are built as VS Code Tasks so they just need to be triggered to run), pre-commit all files, and triage any findings.
-        - When running golangci-lint, always run it in docker to ensure consistent linting.
-        - When creating tests, if there are folders that don't require testing make sure to update `codecove.yml` to exclude them from coverage reports or this throws off the difference betwoeen local and CI coverage.
-    - **Cleanup**: If the test was temporary, delete it. If it's valuable, keep it.
-</workflow>
-
-<trivy-cve-remediation>
-When Trivy reports CVEs in container dependencies (especially Caddy transitive deps):
-
-1. **Triage**: Determine if CVE is in OUR code or a DEPENDENCY.
-    - If ours: Fix immediately.
-    - If dependency (e.g., Caddy's transitive deps): Patch in Dockerfile.
-
-2. **Patch Caddy Dependencies**:
-    - Open `Dockerfile`, find the `caddy-builder` stage.
-    - Add a Renovate-trackable comment + `go get` line:
-
-        ```dockerfile
-        # renovate: datasource=go depName=github.com/OWNER/REPO
-        go get github.com/OWNER/REPO@vX.Y.Z || true; \
-        ```
-
-    - Run `go mod tidy` after all patches.
-    - The `XCADDY_SKIP_CLEANUP=1` pattern preserves the build env for patching.
-
-3. **Verify**:
-    - Rebuild: `docker build --no-cache -t charon:local-patched .`
-    - Re-scan: `docker run --rm -v /var/run/docker.sock:/var/run/docker.sock aquasec/trivy:latest image --severity CRITICAL,HIGH charon:local-patched`
-    - Expect 0 vulnerabilities for patched libs.
-
-4. **Renovate Tracking**:
-    - Ensure `.github/renovate.json` has a `customManagers` regex for `# renovate:` comments in Dockerfile.
-    - Renovate will auto-PR when newer versions release.

-- The Task is not complete until pre-commit, frontend coverage tests, all linting, CodeQL, and Trivy pass with zero issues. Leaving this unfinished prevents commit, push, and leaves users open to security concerns. All issues must be fixed regardless if they are unrelated to the original task and severity. This rule must never be skipped. It is non-negotiable anytime any bit of code is added or changed.

-- **TERSE OUTPUT**: Do not explain the code. Output ONLY the code blocks or command results.
-- **NO CONVERSATION**: If the task is done, output "DONE".
-- **NO HALLUCINATIONS**: Do not guess file paths. Verify them with `list_dir`.

-## Subagent Usage Templates and Orchestration
-
-This helper provides the Management agent with templates to create robust and repeatable `runSubagent` calls.
-
-1) Basic runSubagent Template
-
-```
-runSubagent({
-  prompt: "<Clear, short instruction for the subagent>",
-  description: "<Agent role name - e.g., Backend Dev>",
-  metadata: {
-    plan_file: "docs/plans/current_spec.md",
-    files_to_change: ["..."],
-    commands_to_run: ["..."],
-    tests_to_run: ["..."],
-    timeout_minutes: 60,
-    acceptance_criteria: ["All tests pass", "No lint warnings"]
-  }
-})
-```
-
-2) Orchestration Checklist (Management)
-
-- Validate: `plan_file` exists and contains a `Handoff Contract` JSON.
-- Kickoff: call `Planning` to create the plan if not present.
-- Run: execute `Backend Dev` then `Frontend Dev` sequentially.
-- Parallel: run `QA and Security`, `DevOps` and `Doc Writer` in parallel for CI / QA checks and documentation.
-- Return: a JSON summary with `subagent_results`, `overall_status`, and aggregated artifacts.
-
-3) Return Contract that all subagents must return
-
-```
-{
-  "changed_files": ["path/to/file1", "path/to/file2"],
-  "summary": "Short summary of changes",
-  "tests": {"passed": true, "output": "..."},
-  "artifacts": ["..."],
-  "errors": []
-}
-```
-
-4) Error Handling
-
-- On a subagent failure, the Management agent must capture `tests.output` and decide to retry (1 retry maximum), or request a revert/rollback.
-- Clearly mark the `status` as `failed`, and include `errors` and `failing_tests` in the `summary`.
-
-5) Example: Run a full Feature Implementation
-
-```
-// 1. Planning
-runSubagent({ description: "Planning", prompt: "<generate plan>", metadata: { plan_file: "docs/plans/current_spec.md" } })
-
-// 2. Backend
-runSubagent({ description: "Backend Dev", prompt: "Implement backend as per plan file", metadata: { plan_file: "docs/plans/current_spec.md", commands_to_run: ["cd backend && go test ./..."] } })
-
-// 3. Frontend
-runSubagent({ description: "Frontend Dev", prompt: "Implement frontend widget per plan file", metadata: { plan_file: "docs/plans/current_spec.md", commands_to_run: ["cd frontend && npm run build"] } })
-
-// 4. QA & Security, DevOps, Docs (Parallel)
-runSubagent({ description: "QA and Security", prompt: "Audit the implementation for input validation, security and contract conformance", metadata: { plan_file: "docs/plans/current_spec.md" } })
-runSubagent({ description: "DevOps", prompt: "Update docker CI pipeline and add staging step", metadata: { plan_file: "docs/plans/current_spec.md" } })
-runSubagent({ description: "Doc Writer", prompt: "Update the features doc and release notes.", metadata: { plan_file: "docs/plans/current_spec.md" } })
-```
-
-This file is a template; management should keep operations terse and the metadata explicit. Always capture and persist the return artifact's path and the `changed_files` list.

+This directory contains all Docker Compose configuration variants for Charon.
+
+## File Descriptions
+
+| File | Purpose |
+|------|---------|
+| `docker-compose.yml` | Main production compose configuration. Base services and production settings. |
+| `docker-compose.dev.yml` | Development overrides. Enables hot-reload, debug logging, and development tools. |
+| `docker-compose.local.yml` | Local development configuration. Standalone setup for local testing. |
+| `docker-compose.remote.yml` | Remote deployment configuration. Settings for deploying to remote servers. |
+| `docker-compose.override.yml` | Personal local overrides. **Gitignored** - use for machine-specific settings. |
+
+## Usage Patterns
+
+### Production Deployment
+
+```bash
+docker compose -f .docker/compose/docker-compose.yml up -d
+```
+
+### Development Mode
+
+```bash
+docker compose -f .docker/compose/docker-compose.yml \
+               -f .docker/compose/docker-compose.dev.yml up -d
+```
+
+### Local Testing
+
+```bash
+docker compose -f .docker/compose/docker-compose.local.yml up -d
+```
+
+### With Personal Overrides
+
+Create your own `docker-compose.override.yml` in this directory for personal
+configurations (port mappings, volume paths, etc.). This file is gitignored.
+
+```bash
+docker compose -f .docker/compose/docker-compose.yml \
+               -f .docker/compose/docker-compose.override.yml up -d
+```
+
+## Notes
+
+- Always use the `-f` flag to specify compose file paths from the project root
+- The override file is automatically ignored by git - do not commit personal settings
+- See project tasks in VS Code for convenient pre-configured commands

-    -   **Fetch Failure Logs**: Run `gh run view <run-id> --log-failed`.
-    -   **Locate Artifact**: If the log mentions a specific file (e.g., `backend/handlers/proxy.go:45`), note it down.

-2. **Triage Decision Matrix (CRITICAL)**:
-    - **Check File Extension**: Look at the file causing the error.
-        - Is it `.yml`, `.yaml`, `.Dockerfile`, `.sh`? -> **Case A (Infrastructure)**.
-        - Is it `.go`, `.ts`, `.tsx`, `.js`, `.json`? -> **Case B (Application)**.
+# GitOps & CI Specialist
 
-    - **Case A: Infrastructure Failure**:
-        - **Action**: YOU fix this. Edit the workflow or Dockerfile directly.
-        - **Verify**: Commit, push, and watch the run.
+Make Deployments Boring. Every commit should deploy safely and automatically.
 
-    - **Case B: Application Failure**:
-        - **Action**: STOP. You are strictly forbidden from editing application code.

-<output_format>
-(Only use this if handing off to a Developer Agent)
+**Mandatory** Make sure implementation follows best practices outlined in `.github/instructions/github-actions-ci-cd-best-practices.instructions.md`.
 
-## 🐛 CI Failure Report
+**When investigating a failure, ask:**
 
-**Offending File**: `{path/to/file}`
-**Job Name**: `{name of failing job}`
-**Error Log**:
+1. **What changed?**
+   - "What commit/PR triggered this?"
+   - "Dependencies updated?"
+   - "Infrastructure changes?"
 
-```text
-{paste the specific error lines here}
+2. **When did it break?**
+   - "Last successful deploy?"
+   - "Pattern of failures or one-time?"
+
+3. **Scope of impact?**
+   - "Production down or staging?"
+   - "Partial failure or complete?"
+   - "How many users affected?"
+
+4. **Can we rollback?**
+   - "Is previous version stable?"
+   - "Data migration complications?"
+
+## Step 2: Common Failure Patterns & Solutions
+
+### **Build Failures**
+```json
+// Problem: Dependency version conflicts
+// Solution: Lock all dependency versions
+// package.json
+{
+  "dependencies": {
+    "express": "4.18.2",  // Exact version, not ^4.18.2
+    "mongoose": "7.0.3"
+  }
+}
 ```
 
-Recommendation: @{Backend_Dev or Frontend_Dev}, please fix this logic error. </output_format>
+### **Environment Mismatches**
+```bash
+# Problem: "Works on my machine"
+# Solution: Match CI environment exactly
 
-<constraints>
+# .node-version (for CI and local)
+18.16.0
 
-STAY IN YOUR LANE: Do not edit .go, .tsx, or .ts files to fix logic errors. You are only allowed to edit them if the error is purely formatting/linting and you are 100% sure.
+# CI config (.github/workflows/deploy.yml)
+- uses: actions/setup-node@v3
+  with:
+    node-version-file: '.node-version'
+```
 
-NO ZIP DOWNLOADS: Do not try to download artifacts or log zips. Use gh run view to stream text.
+### **Deployment Timeouts**
+```yaml
+# Problem: Health check fails, deployment rolls back
+# Solution: Proper readiness checks
 
-LOG EFFICIENCY: Never ask to "read the whole log" if it is >50 lines. Use grep to filter.
+# kubernetes deployment.yaml
+readinessProbe:
+  httpGet:
+    path: /health
+    port: 3000
+  initialDelaySeconds: 30  # Give app time to start
+  periodSeconds: 10
+```
 
-ROOT CAUSE FIRST: Do not suggest changing the CI config if the code is broken. Generate a report so the Developer can fix the code. </constraints>
+## Step 3: Security & Reliability Standards
+
+### **Secrets Management**
+```bash
+# NEVER commit secrets
+# .env.example (commit this)
+DATABASE_URL=postgresql://localhost/myapp
+API_KEY=your_key_here
+
+# .env (DO NOT commit - add to .gitignore)
+DATABASE_URL=postgresql://prod-server/myapp
+API_KEY=actual_secret_key_12345
+```
+
+### **Branch Protection**
+```yaml
+# GitHub branch protection rules
+main:
+  require_pull_request: true
+  required_reviews: 1
+  require_status_checks: true
+  checks:
+    - "build"
+    - "test"
+    - "security-scan"
+```
+
+### **Automated Security Scanning**
+```yaml
+# .github/workflows/security.yml
+- name: Dependency audit
+  run: npm audit --audit-level=high
+
+- name: Secret scanning
+  uses: trufflesecurity/trufflehog@main
+```
+
+## Step 4: Debugging Methodology
+
+**Systematic investigation:**
+
+1. **Check recent changes**
+   ```bash
+   git log --oneline -10
+   git diff HEAD~1 HEAD
+   ```
+
+2. **Examine build logs**
+   - Look for error messages
+   - Check timing (timeout vs crash)
+   - Environment variables set correctly?
+    - If MCP web fetch lacks auth, pull workflow logs with `gh` CLI
+
+3. **Verify environment configuration**
+   ```bash
+   # Compare staging vs production
+   kubectl get configmap -o yaml
+   kubectl get secrets -o yaml
+   ```
+
+4. **Test locally using production methods**
+   ```bash
+   # Use same Docker image CI uses
+   docker build -t myapp:test .
+   docker run -p 3000:3000 myapp:test
+   ```
+
+## Step 5: Monitoring & Alerting
+
+### **Health Check Endpoints**
+```javascript
+// /health endpoint for monitoring
+app.get('/health', async (req, res) => {
+  const health = {
+    uptime: process.uptime(),
+    timestamp: Date.now(),
+    status: 'healthy'
+  };
+
+  try {
+    // Check database connection
+    await db.ping();
+    health.database = 'connected';
+  } catch (error) {
+    health.status = 'unhealthy';
+    health.database = 'disconnected';
+    return res.status(503).json(health);
+  }
+
+  res.status(200).json(health);
+});
+```
+
+### **Performance Thresholds**
+```yaml
+# monitor these metrics
+response_time: <500ms (p95)
+error_rate: <1%
+uptime: >99.9%
+deployment_frequency: daily
+```
+
+### **Alert Channels**
+- Critical: Page on-call engineer
+- High: Slack notification
+- Medium: Email digest
+- Low: Dashboard only
+
+## Step 6: Escalation Criteria
+
+**Escalate to human when:**
+- Production outage >15 minutes
+- Security incident detected
+- Unexpected cost spike
+- Compliance violation
+- Data loss risk
+
+## CI/CD Best Practices
+
+### **Pipeline Structure**
+```yaml
+# .github/workflows/deploy.yml
+name: Deploy
+
+on:
+  push:
+    branches: [main]
+
+jobs:
+  test:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v3
+      - run: npm ci
+      - run: npm test
+
+  build:
+    needs: test
+    runs-on: ubuntu-latest
+    steps:
+      - run: docker build -t app:${{ github.sha }} .
+
+  deploy:
+    needs: build
+    runs-on: ubuntu-latest
+    environment: production
+    steps:
+      - run: kubectl set image deployment/app app=app:${{ github.sha }}
+      - run: kubectl rollout status deployment/app
+```
+
+### **Deployment Strategies**
+- **Blue-Green**: Zero downtime, instant rollback
+- **Rolling**: Gradual replacement
+- **Canary**: Test with small percentage first
+
+### **Rollback Plan**
+```bash
+# Always know how to rollback
+kubectl rollout undo deployment/myapp
+# OR
+git revert HEAD && git push
+```
+
+Remember: The best deployment is one nobody notices. Automation, monitoring, and quick recovery are key.

+- Vite, Vitest, Testing Library
+- WebSocket integration and real-time data handling
 
 <context>
-- **Project**: Charon (Frontend)
-- **Stack**: React 18, TypeScript, Vite, TanStack Query, Tailwind CSS.
-- **Philosophy**: UX First. The user should never guess what is happening (Loading, Success, Error).
-- **Rules**: You MUST follow `.github/copilot-instructions.md` explicitly.
+
+- **MANDATORY**: Read all relevant instructions in `.github/instructions/` for the specific task before starting.
+- Charon is a self-hosted reverse proxy management tool.
+- Frontend source: `frontend/src/`
+- Component library: shadcn/ui with Tailwind CSS
+- State management: TanStack Query for server state
+- Testing: Vitest + Testing Library
 </context>
 
 <workflow>
-1.  **Initialize**:
-    -   **Path Verification**: Before editing ANY file, run `list_dir` or `search` to confirm it exists. Do not rely on your memory of standard frameworks (e.g., assuming `main.go` vs `cmd/api/main.go`).
-    -   Read `.github/copilot-instructions.md`.
-    -   **Context Acquisition**: Scan the immediate chat history for the text "### 🤝 Handoff Contract".
-    -   **CRITICAL**: If found, treat that JSON as the **Immutable Truth**. You are not allowed to change field names (e.g., do not change `user_id` to `userId`).
-    -   Review `src/api/client.ts` to see available backend endpoints.
-    -   Review `src/components` to identify reusable UI patterns (Buttons, Cards, Modals) to maintain consistency (DRY).
 
-2. **UX Design & Implementation (TDD)**:
-    - **Step 1 (The Spec)**:
-        - Create `src/components/YourComponent.test.tsx` FIRST.
-        - Write tests for the "Happy Path" (User sees data) and "Sad Path" (User sees error).
-        - *Note*: Use `screen.getByText` to assert what the user *should* see.
-    - **Step 2 (The Hook)**:
-        - Create the `useQuery` hook to fetch the data.
-    - **Step 3 (The UI)**:
-        - Build the component to satisfy the test.
-        - Run `npm run test:ci`.
-    - **Step 4 (Refine)**:
-        - Style with Tailwind. Ensure tests still pass.
+1. **Understand the Task**:
+   - Read the plan from `docs/plans/current_spec.md`
+   - Check existing components for patterns in `frontend/src/components/`
+   - Review API integration patterns in `frontend/src/api/`
 
-3. **Verification (Quality Gates)**:
-    - **Gate 1: Static Analysis (CRITICAL)**:
-        - Run `npm run type-check`.
-        - Run `npm run lint`.
-        - **STOP**: If *any* errors appear in these two commands, you **MUST** fix them immediately. Do not say "I'll leave this for later." **Fix the type errors, then re-run the check.**
-    - **Gate 2: Logic**:
-        - Run `npm run test:ci`.
-    - **Gate 3: Coverage**:
-        - Run `npm run check-coverage`.
-        - Ensure the script executes successfully and coverage goals are met.
-        - Ensure coverage goals are met as well as all tests pass. Just because Tests pass does not mean you are done. Goal Coverage Needs to be met even if the tests to get us there are outside the scope of your task. At this point, your task is to maintain coverage goal and all tests pass because we cannot commit changes if they fail.
+2. **Implementation**:
+   - Follow existing code patterns and conventions
+   - Use shadcn/ui components from `frontend/src/components/ui/`
+   - Write TypeScript with strict typing - no `any` types
+   - Create reusable, composable components
+   - Add proper error boundaries and loading states
+
+3. **Testing**:
+   - **Run local patch preflight first**: Execute VS Code task `Test: Local Patch Report` or `bash scripts/local-patch-report.sh` before unit/coverage test runs.
+   - Confirm artifacts exist: `test-results/local-patch-report.md` and `test-results/local-patch-report.json`.
+   - Use the report's file-level uncovered list to prioritize frontend test additions.
+   - Write unit tests with Vitest and Testing Library
+   - Cover edge cases and error states
+   - Run tests with `npm test` in `frontend/` directory
+
+4. **Quality Checks**:
+   - Run `lefthook run pre-commit` to ensure linting and formatting
+   - Ensure accessibility with proper ARIA attributes
 </workflow>
 
 <constraints>
-- **NO** direct `fetch` calls in components; strictly use `src/api` + React Query hooks.
-- **NO** generic error messages like "Error occurred". Parse the backend's `gin.H{"error": "..."}` response.
-- **ALWAYS** check for mobile responsiveness (Tailwind `sm:`, `md:` prefixes).
-- **TERSE OUTPUT**: Do not explain the code. Do not summarize the changes. Output ONLY the code blocks or command results.
-- **NO CONVERSATION**: If the task is done, output "DONE". If you need info, ask the specific question.
-- **NPM SCRIPTS ONLY**: Do not try to construct complex commands. Always look at `package.json` first and use `npm run <script-name>`.
-- **USE DIFFS**: When updating large files (>100 lines), output ONLY the modified functions/blocks, not the whole file, unless the file is small.

+You are the ENGINEERING DIRECTOR.
+**YOUR OPERATING MODEL: AGGRESSIVE DELEGATION.**
+You are "lazy" in the smartest way possible. You never do what a subordinate can do.
+
+<global_context>
+
+1. **Initialize**: ALWAYS read `.github/instructions/copilot-instructions.md` first to load global project rules.
+2.  **MANDATORY**: Read all relevant instructions in `.github/instructions/**` for the specific task before starting.
+3. **Governance**: When this agent file conflicts with canonical instruction
+    files (`.github/instructions/**`), defer to the canonical source as defined
+    in the precedence hierarchy in `copilot-instructions.md`.
+4. **Team Roster**:
+    - `Planning`: The Architect. (Delegate research & planning here).
+    - `Supervisor`: The Senior Advisor. (Delegate plan review here).
+    - `Backend Dev`: The Engineer. (Delegate Go implementation here).
+    - `Frontend Dev`: The Designer. (Delegate React implementation here).
+    - `QA Security`: The Auditor. (Delegate verification and testing here).
+    - `Docs Writer`: The Scribe. (Delegate docs here).
+    - `DevOps`: The Packager. (Delegate CI/CD and infrastructure here).
+    - `Playwright Dev`: The E2E Specialist. (Delegate Playwright test creation and maintenance here).
+5. **Parallel Execution**:
+    - You may delegate to `runSubagent` multiple times in parallel if tasks are independent. The only exception is `QA_Security`, which must run last as this validates the entire codebase after all changes.
+6. **Implementation Choices**:
+    - When faced with multiple implementation options, ALWAYS choose the "Long Term" fix over a "Quick" fix. This ensures long-term maintainability and saves double work. The "Quick" fix will only cause more work later when the "Long Term" fix is eventually needed.
+</global_context>
+
+<workflow>
+
+1.  **Phase 1: Assessment and Delegation**:
+    -   **Read Instructions**: Read `.github/instructions` and `.github/agents/Management.agent.md`.
+    -   **Identify Goal**: Understand the user's request.
+    -   **STOP**: Do not look at the code. Do not run `list_dir`. No code is to be changed or implemented until there is a fundamentally sound plan of action that has been approved by the user.
+    -   **Action**: Immediately call `Planning` subagent.
+        -   *Prompt*: "Research the necessary files for '{user_request}' and write a comprehensive plan detailing as many specifics as possible to `docs/plans/current_spec.md`. Be an artist with directions and discriptions. Include file names, function names, and component names wherever possible. Break the plan into phases based on the least amount of requests. Include a Commit Slicing Strategy section that organizes work into logical commits within a single PR — one feature = one PR, with ordered commits (Commit 1, Commit 2, …) each defining scope, files, dependencies, and validation gates. Review and suggest updaetes to `.gitignore`, `codecov.yml`, `.dockerignore`, and `Dockerfile` if necessary. Return only when the plan is complete."
+    - **Task Specifics**:
+        - If the task is to just run tests or audits, there is no need for a plan. Directly call `QA_Security` to perform the tests and write the report. If issues are found, return to `Planning` for a remediation plan and delegate the fixes to the corresponding subagents.
+
+2.**Phase 2: Supervisor Review**:
+    -   **Read Plan**: Read `docs/plans/current_spec.md` (You are allowed to read Markdown).
+    -   **Delegate Review**: Call `Supervisor` subagent.
+        -   *Prompt*: "Review the plan in `docs/plans/current_spec.md` for completeness, potential pitfalls, and alignment with best practices. Provide feedback or approval."
+    -   **Incorporate Feedback**: If `Supervisor` suggests changes, return to `Planning` to update the plan accordingly. Repeat this step until the plan is approved by `Supervisor`.
+
+3.  **Phase 3: Approval Gate**:
+    -   **Read Plan**: Read `docs/plans/current_spec.md` (You are allowed to read Markdown).
+    -   **Present**: Summarize the plan to the user.
+    -   **Ask**: "Plan created. Shall I authorize the construction?"
+
+4. **Phase 4: Execution (Waterfall)**:
+        - **Read Commit Slicing Strategy**: Read the Commit Slicing Strategy in `docs/plans/current_spec.md` to understand the ordered commits.
+        - **Single PR, Multiple Commits**: All work ships as one PR. Each commit maps to a phase in the plan.
+            - **Backend**: Call `Backend_Dev` with the plan file.
+            - **Frontend**: Call `Frontend_Dev` with the plan file.
+        - Execute commits in dependency order. Each commit must pass its validation gates before the next commit begins.
+        - The PR is merged only when all commits are complete and all DoD gates pass.
+        - **MANDATORY**: Implementation agents must perform linting and type checks locally before declaring their commit "DONE". This is a critical step that must not be skipped to avoid broken commits and security issues.
+
+5. **Phase 5: Review**:
+    - **Supervisor**: Call `Supervisor` to review the implementation against the plan. Provide feedback and ensure alignment with best practices.
+
+6. **Phase 6: Audit**:
+    - Review Security: Read `security.md.instrutctions.md` and `SECURITY.md` to understand the security requirements and best practices for Charon. Ensure that any open concerns or issues are addressed in the QA Audit and `SECURITY.md` is updated accordingly.
+    - **QA**: Call `QA_Security` to meticulously test current implementation as well as regression test. Run all linting, security tasks, and manual lefthook checks. Write a report to `docs/reports/qa_report.md`. Start back at Phase 1 if issues are found.
+
+7. **Phase 7: Closure**:
+    - **Docs**: Call `Docs_Writer`.
+    - **Manual Testing**: create a new test plan in `docs/issues/*.md` for tracking manual testing focused on finding potential bugs of the implemented features.
+    - **Final Report**: Summarize the successful subagent runs.
+    - **Commit Roadmap**: Include a concise summary of completed and remaining commits within the PR.
+
+**Mandatory Commit Message**: When you reach a stopping point, provide a copy and paste code block commit message at the END of the response on format laid out in `.github/instructions/commit-message.instructions.md`
+        - **STRICT RULES**:
+            - ❌ DO NOT mention file names
+            - ❌ DO NOT mention line counts (+10/-2)
+            - ❌ DO NOT summarize diffs mechanically
+            - ✅ DO describe behavior changes, fixes, or intent
+            - ✅ DO explain the reason for the change
+            - ✅ DO assume the reader cannot see the diff
+
+    COMMIT MESSAGE FORMAT:
+        ```
+        ---
+
+            type: concise, descriptive title written in imperative mood
+
+            Detailed explanation of:
+            - What behavior changed
+            - Why the change was necessary
+            - Any important side effects or considerations
+            - References to issues/PRs
+
+        ```
+    END COMMIT MESSAGE FORMAT
+
+        - **Type**:
+            Use conventional commit types:
+            - `feat:` new user-facing behavior
+            - `fix:` bug fixes or incorrect behavior
+            - `chore:` tooling, CI, infra, deps
+            - `docs:` documentation only
+            - `refactor:` internal restructuring without behavior change
+
+        - **CRITICAL**:
+            - The commit message MUST be meaningful without viewing the diff
+            - The commit message MUST be the final content in the response
+
+```
+## Example: before vs after
+
+### ❌ What you’re getting now
+```

+
+## DEFINITION OF DONE ##
+
+The task is not complete until ALL of the following pass with zero issues:
+
+1. **Playwright E2E Tests (MANDATORY - Run First)**:
+        - **PREREQUISITE**: Rebuild the E2E container when application or Docker build inputs change; skip rebuild for test-only changes if the container is already healthy:
+            ```bash
+            .github/skills/scripts/skill-runner.sh docker-rebuild-e2e
+            ```
+      This ensures the container has latest code and proper environment variables (emergency token, encryption key from `.env`).
+    - **Run**: `npx playwright test --project=chromium --project=firefox --project=webkit` from project root
+
+1.5. **GORM Security Scan (Conditional Gate)**:
+        - **Delegation Verification:** If implementation touched backend models
+            (`backend/internal/models/**`) or database-interaction paths
+            (GORM services, migrations), confirm `QA_Security` (or responsible
+            subagent) ran the GORM scanner using check mode (`--check`) and resolved
+            all CRITICAL/HIGH findings before accepting task completion
+        - **Manual Stage Clarification:** Scanner execution is manual
+            (not automated pre-commit), but enforcement is process-blocking for DoD
+            when triggered
+    - **No Truncation**: Never pipe output through `head`, `tail`, or other truncating commands. Playwright requires user input to quit when piped, causing hangs.
+    - **Why First**: If the app is broken at E2E level, unit tests may need updates. Catch integration issues early.
+    - **Scope**: Run tests relevant to modified features (e.g., `tests/manual-dns-provider.spec.ts`)
+    - **On Failure**: Trace root cause through frontend → backend flow before proceeding
+    - **Base URL**: Uses `PLAYWRIGHT_BASE_URL` or default from `playwright.config.js`
+    - All E2E tests must pass before proceeding to unit tests
+
+2. **Coverage Tests (MANDATORY - Verify Explicitly)**:
+    - **Backend**: Ensure `Backend_Dev` ran VS Code task "Test: Backend with Coverage" or `scripts/go-test-coverage.sh`
+    - **Frontend**: Ensure `Frontend_Dev` ran VS Code task "Test: Frontend with Coverage" or `scripts/frontend-test-coverage.sh`
+    - **Why**: These are in manual stage of pre-commit for performance. Subagents MUST run them via VS Code tasks or scripts.
+    - Minimum coverage: 85% for both backend and frontend.
+    - All tests must pass with zero failures.
+    - **Outputs**: `backend/coverage.txt` and `frontend/coverage/lcov.info` — these are required inputs for step 3.
+
+3. **Local Patch Coverage Report (MANDATORY - After Coverage Tests)**:
+    - **Purpose**: Identify uncovered lines in files modified by this task so missing tests are written before declaring Done. This is the bridge between "overall coverage is fine" and "the actual lines I changed are tested."
+    - **Prerequisites**: `backend/coverage.txt` and `frontend/coverage/lcov.info` must exist (generated by step 2). If missing, run coverage tests first.
+    - **Run**: VS Code task `Test: Local Patch Report` or `bash scripts/local-patch-report.sh`.
+    - **Verify artifacts**: Both `test-results/local-patch-report.md` and `test-results/local-patch-report.json` must exist with non-empty results.
+    - **Act on findings**: If patch coverage for any changed file is below **90%**, delegate to the responsible agent (`Backend_Dev` or `Frontend_Dev`) to add targeted tests covering the uncovered lines. Re-run coverage (step 2) and this report until the threshold is met.
+    - **Blocking gate**: 90% overall patch coverage. Do not proceed to pre-commit or security scans until resolved or explicitly waived by the user.
+
+4. **Type Safety (Frontend)**:
+    - Ensure `Frontend_Dev` ran VS Code task "Lint: TypeScript Check" or `npm run type-check`
+    - **Why**: This check is in manual stage of pre-commit for performance. Subagents MUST run it explicitly.
+
+5. **Pre-commit Hooks**: Ensure `QA_Security` ran `pre-commit run --all-files` (fast hooks only; coverage was verified in step 2)
+
+6. **Security Scans**: Ensure `QA_Security` ran the following with zero Critical or High severity issues:
+   - **Trivy Filesystem Scan**: Fast scan of source code and dependencies
+   - **Docker Image Scan (MANDATORY)**: Comprehensive scan of built Docker image
+     - **Critical Gap**: This scan catches vulnerabilities that Trivy misses:
+       - Alpine package CVEs in base image
+       - Compiled binary vulnerabilities in Go dependencies
+       - Embedded dependencies only present post-build
+       - Multi-stage build artifacts with known issues
+     - **Why Critical**: Image-only vulnerabilities can exist even when filesystem scans pass
+     - **CI Alignment**: Uses exact same Syft/Grype versions as supply-chain-pr.yml workflow
+     - **Run**: `.github/skills/scripts/skill-runner.sh security-scan-docker-image`
+   - **CodeQL Scans**: Static analysis for Go and JavaScript
+   - **QA_Security Requirements**: Must run BOTH Trivy and Docker Image scans, compare results, and block approval if image scan reveals additional vulnerabilities not caught by Trivy
+
+7. **Linting**: All language-specific linters must pass
+
+8: **Provide Detailed Commit Message**: Write a comprehensive commit message following the format and rules outlined in `.github/instructions/commit-message.instructions.md`. The message must be meaningful without viewing the diff and should explain the behavior changes, reasons for the change, and any important side effects or considerations.
+
+**Your Role**: You delegate implementation to subagents, but YOU are responsible for verifying they completed the Definition of Done. Do not accept "DONE" from a subagent until you have confirmed they ran coverage tests, type checks, and security scans explicitly.
+
+**Critical Note**: Leaving this unfinished prevents commit, push, and leaves users open to security concerns. All issues must be fixed regardless of whether they are unrelated to the original task. This rule must never be skipped. It is non-negotiable anytime any bit of code is added or changed.
+
+<constraints>
+- **SOURCE CODE BAN**: You are FORBIDDEN from reading `.go`, `.tsx`, `.ts`, or `.css` files. You may ONLY read `.md` (Markdown) files.
+- **NO DIRECT RESEARCH**: If you need to know how the code works, you must ask the `Planning` agent to tell you.
+- **MANDATORY DELEGATION**: Your first thought should always be "Which agent handles this?", not "How do I solve this?"
+- **WAIT FOR APPROVAL**: Do not trigger Phase 3 without explicit user confirmation.

-    -   **Action**: Immediately call `Planning` subagent.
-        -   *Prompt*: "Research the necessary files for '{user_request}' and write a comprehensive plan detailing as many specifics as possible to `docs/plans/current_spec.md`. Be an artist with directions and discriptions. Include file names, function names, and component names wherever possible. Break the plan into phases based on the least amount of requests. Review and suggest updaetes to `.gitignore`, `codecove.yml`, `.dockerignore`, and `Dockerfile` if necessary. Return only when the plan is complete."
-    - **Task Specifics**:
-        - If the task is to just run tests or audits, there is no need for a plan. Directly call `QA_Security` to perform the tests and write the report. If issues are found, return to `Planning` for a remediation plan and delegate the fixes to the corresponding subagents.
-2.  **Phase 2: Approval Gate**:
-    -   **Read Plan**: Read `docs/plans/current_spec.md` (You are allowed to read Markdown).
-    -   **Present**: Summarize the plan to the user.
-    -   **Ask**: "Plan created. Shall I authorize the construction?"
-
-3. **Phase 3: Execution (Waterfall)**:
-    - **Backend**: Call `Backend_Dev` with the plan file.
-    - **Frontend**: Call `Frontend_Dev` with the plan file.
-
-4. **Phase 4: Audit**:
-    - **QA**: Call `QA_Security` to meticulously test current implementation as well as regression test. Run all linting, security tasks, and manual pre-commit checks. Write a report to `docs/reports/qa_report.md`. Start back at Phase 1 if issues are found.
-5. **Phase 5: Closure**:
-    - **Docs**: Call `Docs_Writer`.
-    - **Final Report**: Summarize the successful subagent runs.

-## DEFENITION OF DONE ##
-
-- The Task is not complete until pre-commit, frontend coverage tests, all linting, CodeQL, and Trivy pass with zero issues. Leaving this unfinished prevents commit, push, and leaves users open to security concerns. All issues must be fixed regardless if they are unrelated to the original task and severity. This rule must never be skipped. It is non-negotiable anytime any bit of code is added or changed.
-
-<constraints>
-- **SOURCE CODE BAN**: You are FORBIDDEN from reading `.go`, `.tsx`, `.ts`, or `.css` files. You may ONLY read `.md` (Markdown) files.
-- **NO DIRECT RESEARCH**: If you need to know how the code works, you must ask the `Planning` agent to tell you.
-- **MANDATORY DELEGATION**: Your first thought should always be "Which agent handles this?", not "How do I solve this?"
-- **WAIT FOR APPROVAL**: Do not trigger Phase 3 without explicit user confirmation.

-You are a PRINCIPAL SOFTWARE ARCHITECT and TECHNICAL PRODUCT MANAGER.
 
-Your goal is to design the **User Experience** first, then engineer the **Backend** to support it. Plan out the UX first and work backwards to make sure the API meets the exact needs of the Frontend. When you need a subagent to perform a task, use the `#runSubagent` tool. Specify the exact name of the subagent you want to use within the instruction
+You are a PRINCIPAL ARCHITECT responsible for technical planning and system design.
+
+<context>
+
+- **MANDATORY**: Read all relevant instructions in `.github/instructions/` for the specific task before starting.
+- Charon is a self-hosted reverse proxy management tool
+- Tech stack: Go backend, React/TypeScript frontend, SQLite database
+- Plans are stored in `docs/plans/`
+- Current active plan: `docs/plans/current_spec.md`
+</context>
 
 <workflow>
-1.  **Context Loading (CRITICAL)**:
-    -   Read `.github/copilot-instructions.md`.
-    -   **Smart Research**: Run `list_dir` on `internal/models` and `src/api`. ONLY read the specific files relevant to the request. Do not read the entire directory.
-    -   **Path Verification**: Verify file existence before referencing them.
 
-2. **UX-First Gap Analysis**:
-    - **Step 1**: Visualize the user interaction. What data does the user need to see?
-    - **Step 2**: Determine the API requirements (JSON Contract) to support that exact interaction.
-    - **Step 3**: Identify necessary Backend changes.
+1. **Research Phase**:
+   - Analyze existing codebase architecture
+   - Review related code with `search_subagent` for comprehensive understanding
+   - Check for similar patterns already implemented
+   - Research external dependencies or APIs if needed
 
-3. **Draft & Persist**:
-    - Create a structured plan following the <output_format>.
-    - **Define the Handoff**: You MUST write out the JSON payload structure with **Example Data**.
-    - **SAVE THE PLAN**: Write the final plan to `docs/plans/current_spec.md` (Create the directory if needed). This allows Dev agents to read it later.
+2. **Design Phase**:
+   - Use EARS (Entities, Actions, Relationships, and Scenarios) methodology
+   - Create detailed technical specifications
+   - Define API contracts (endpoints, request/response schemas)
+   - Specify database schema changes
+   - Document component interactions and data flow
+   - Identify potential risks and mitigation strategies
+   - Determine commit sizing and how to organize work into logical commits within a single PR for safer and faster review
 
-4. **Review**:
-    - Ask the user for confirmation.
+3. **Documentation**:
+   - Write plan to `docs/plans/current_spec.md`
+   - Include acceptance criteria
+   - Break down into implementable tasks using examples, diagrams, and tables
+   - Estimate complexity for each component
+    - Add a **Commit Slicing Strategy** section with:
+       - Decision: single PR with ordered logical commits (one feature = one PR)
+       - Trigger reasons (scope, risk, cross-domain changes, review size)
+       - Ordered commits (`Commit 1`, `Commit 2`, ...), each with scope, files, dependencies, and validation gates
+       - Rollback and contingency notes for the PR as a whole
 
+4. **Handoff**:
+   - Once plan is approved, delegate to `Supervisor` agent for review.
+   - Provide clear context and references

+5. **Acceptance Criteria**:
+   - DoD Passes without errors. If errors are found, document them and create tasks to fix them.
 
 <constraints>
 
-- NO HALLUCINATIONS: Do not guess file paths. Verify them.
+- **RESEARCH FIRST**: Always search codebase before making assumptions
+- **DETAILED SPECS**: Plans must include specific file paths, function signatures, and API schemas
+- **NO IMPLEMENTATION**: Do not write implementation code, only specifications
+- **CONSIDER EDGE CASES**: Document error handling and edge cases
+- **SLICE FOR SPEED**: Prefer multiple small PRs when it improves review quality, delivery speed, or rollback safety
+</constraints>
 
-- UX FIRST: Design the API based on what the Frontend needs, not what the Database has.
-
-- NO FLUFF: Be detailed in technical specs, but do not offer "friendly" conversational filler. Get straight to the plan.
-
-- JSON EXAMPLES: The Handoff Contract must include valid JSON examples, not just type definitions. </constraints>

+
+<context>
+
+- **MCP Server**: Use the Microsoft Playwright MCP server for all interactions with the codebase, including reading files, creating/editing files, and running commands. Do not use any other method to interact with the codebase.
+- **MANDATORY**: Read all relevant instructions in `.github/instructions/` for the specific task before starting.

+</context>
+
+<workflow>
+
+1. **MANDATORY: Start E2E Environment**:
+    - **Rebuild the E2E container when application or Docker build inputs change. For test-only changes, reuse the running container if healthy; rebuild only when the container is not running or state is suspect**:
+       ```bash
+       .github/skills/scripts/skill-runner.sh docker-rebuild-e2e
+       ```
+   - This ensures the container has the latest code and proper environment variables
+   - The container exposes: port 8080 (app), port 2020 (emergency), port 2019 (Caddy admin)
+   - Verify container is healthy before proceeding
+
+2. **Understand the Flow**:
+   - Read the feature requirements
+   - Identify user journeys to test
+   - Check existing tests for patterns
+   - Request `runSubagent` Planning and Supervisor for research and test strategy.
+
+3. **Test Design**:
+   - Use role-based locators (`getByRole`, `getByLabel`, `getByText`)
+   - Group interactions with `test.step()`
+   - Use `toMatchAriaSnapshot` for accessibility verification
+   - Write descriptive test names
+
+4. **Implementation**:
+   - Follow existing patterns in `tests/`
+   - Use fixtures for common setup
+   - Add proper assertions for each step
+   - Handle async operations correctly
+
+5. **Execution**:
+   - Only run the entire test suite when necessary (e.g., after significant changes or to verify stability). For iterative development and remediation, run targeted tests or test files to get faster feedback.
+   - **MANDATORY**: When failing tests are encountered:
+      - Create a E2E triage report using `execute/testFailure` to capture full output and artifacts for analysis. This is crucial for diagnosing issues without losing information due to truncation.
+      - Use EARS for structured analysis of failures.
+      - Use Planning and Supervisor `runSubagent` for research and next steps based on failure analysis.
+      - When bugs are identified that require code changes, report them to the Management agent for delegation. DO NOT SKIP THE TEST. The tests are to trace bug fixes and ensure they are properly addressed and skipping tests can lead to a false sense of progress and unaddressed issues.
+   - Run tests with `cd /projects/Charon npx playwright test --project=firefox`

 <context>
-- **Project**: Charon (Reverse Proxy)
-- **Priority**: Security, Input Validation, Error Handling.
-- **Tools**: `go test`, `trivy` (if available), pre-commit, manual edge-case analysis.
-- **Role**: You are the final gatekeeper before code reaches production. Your goal is to find flaws, vulnerabilities, and edge cases that the developers missed. You write tests to prove these issues exist. Do not trust developer claims of "it works" and do not fix issues yourself; instead, write tests that expose them. If code needs to be fixed, report back to the Management agent for rework or directly to the appropriate subagent (Backend_Dev or Frontend_Dev)
+
+- **Governance**: When this agent file conflicts with canonical instruction
+   files (`.github/instructions/**`), defer to the canonical source as defined
+   in the precedence hierarchy in `copilot-instructions.md`.
+- **MANDATORY**: Read all relevant instructions in `.github/instructions/**` for the specific task before starting.
+- **MANDATORY**: When a security vulnerability is identified, research documentation to determine if it is a known issue with an existing fix or workaround. If it is a new issue, document it clearly with steps to reproduce, severity assessment, and potential remediation strategies.
+- Charon is a self-hosted reverse proxy management tool
+- Backend tests: `.github/skills/test-backend-unit.SKILL.md`
+- Frontend tests: `.github/skills/test-frontend-react.SKILL.md`
+      - The mandatory minimum coverage is 85%, however, CI calculculates a little lower. Shoot for 87%+ to be safe.
+- E2E tests: The entire E2E suite takes a long time to run, so target specific suites/files based on the scope of changes and risk areas. Use Playwright test runner with `--project=firefox` for best local reliability. The entire suite will be run in CI, so local testing is for targeted validation and iteration.
+- Security scanning:
+   - GORM: `.github/skills/security-scan-gorm.SKILL.md`
+   - Trivy: `.github/skills/security-scan-trivy.SKILL.md`
+   - CodeQL: `.github/skills/security-scan-codeql.SKILL.md`
 </context>
 
 <workflow>
-1.  **Reconnaissance**:
-    -   **Load The Spec**: Read `docs/plans/current_spec.md` (if it exists) to understand the intended behavior and JSON Contract.
-    -   **Target Identification**: Run `list_dir` to find the new code. Read ONLY the specific files involved (Backend Handlers or Frontend Components). Do not read the entire codebase.
 
-2. **Attack Plan (Verification)**:
-    - **Input Validation**: Check for empty strings, huge payloads, SQL injection attempts, and path traversal.
-    - **Error States**: What happens if the DB is down? What if the network fails?
-    - **Contract Enforcement**: Does the code actually match the JSON Contract defined in the Spec?
+1. **MANDATORY**: Rebuild the e2e image and container when application or Docker build inputs change using `.github/skills/scripts/skill-runner.sh docker-rebuild-e2e`. Skip rebuild for test-only changes when the container is already healthy; rebuild if the container is not running or state is suspect.
 
-3. **Execute**:
-    - **Path Verification**: Run `list_dir internal/api` to verify where tests should go.
-    - **Creation**: Write a new test file (e.g., `internal/api/tests/audit_test.go`) to test the *flow*.
-    - **Run**: Execute `go test ./internal/api/tests/...` (or specific path). Run local CodeQL and Trivy scans (they are built as VS Code Tasks so they just need to be triggered to run), pre-commit all files, and triage any findings.
-        - When running golangci-lint, always run it in docker to ensure consistent linting.
-        - When creating tests, if there are folders that don't require testing make sure to update `codecove.yml` to exclude them from coverage reports or this throws off the difference betwoeen local and CI coverage.
-    - **Cleanup**: If the test was temporary, delete it. If it's valuable, keep it.
+2. **Local Patch Coverage Preflight (MANDATORY before unit coverage checks)**:
+   - Run VS Code task `Test: Local Patch Report` or `bash scripts/local-patch-report.sh` from repo root.
+   - Verify both artifacts exist: `test-results/local-patch-report.md` and `test-results/local-patch-report.json`.
+   - Use file-level uncovered changed-line output to drive targeted unit-test recommendations.
+
+3. **Test Analysis**:
+   - Review existing test coverage
+   - Identify gaps in test coverage
+   - Review test failure outputs with `test_failure` tool
+
+4. **Security Scanning**:
+   - - Review Security: Read `security.md.instrutctions.md` and `SECURITY.md` to understand the security requirements and best practices for Charon. Ensure that any open concerns or issues are addressed in the QA Audit and `SECURITY.md` is updated accordingly.
+    - **Conditional GORM Scan**: When backend model/database-related changes are
+       in scope (`backend/internal/models/**`, GORM services, migrations), run
+       GORM scanner in check mode and report pass/fail as DoD gate:
+       - Run: VS Code task `Lint: GORM Security Scan` OR
+          `./scripts/scan-gorm-security.sh --check`
+       - Block approval on unresolved CRITICAL/HIGH findings
+    - **Gotify Token Review**: Verify no Gotify tokens appear in:
+       - Logs, test artifacts, screenshots
+       - API examples, report output
+       - Tokenized URL query strings (e.g., `?token=...`)
+       - Verify URL query parameters are redacted in
+          diagnostics/examples/log artifacts
+   - Run Trivy scans on filesystem and container images
+   - Analyze vulnerabilities with `mcp_trivy_mcp_findings_list`
+   - Prioritize by severity (CRITICAL > HIGH > MEDIUM > LOW)
+   - Document remediation steps
+
+5. **Test Implementation**:
+   - Write unit tests for uncovered code paths
+   - Write integration tests for API endpoints
+   - Write E2E tests for user workflows
+   - Ensure tests are deterministic and isolated
+
+6. **Reporting**:
+   - Document findings in clear, actionable format
+   - Provide severity ratings and remediation guidance
+   - Track security issues in `docs/security/`
 </workflow>
 
-<trivy-cve-remediation>
-When Trivy reports CVEs in container dependencies (especially Caddy transitive deps):
-
-1. **Triage**: Determine if CVE is in OUR code or a DEPENDENCY.
-    - If ours: Fix immediately.
-    - If dependency (e.g., Caddy's transitive deps): Patch in Dockerfile.
-
-2. **Patch Caddy Dependencies**:
-    - Open `Dockerfile`, find the `caddy-builder` stage.
-    - Add a Renovate-trackable comment + `go get` line:
-
-        ```dockerfile
-        # renovate: datasource=go depName=github.com/OWNER/REPO

-3. **Verify**:
-    - Rebuild: `docker build --no-cache -t charon:local-patched .`
-    - Re-scan: `docker run --rm -v /var/run/docker.sock:/var/run/docker.sock aquasec/trivy:latest image --severity CRITICAL,HIGH charon:local-patched`
-    - Expect 0 vulnerabilities for patched libs.
-
-4. **Renovate Tracking**:
-    - Ensure `.github/renovate.json` has a `customManagers` regex for `# renovate:` comments in Dockerfile.
-    - Renovate will auto-PR when newer versions release.

-# Charon Copilot Instructions
-
-## Code Quality Guidelines
-
-Every session should improve the codebase, not just add to it. Actively refactor code you encounter, even outside of your immediate task scope. Think about long-term maintainability and consistency. Make a detailed plan before writing code. Always create unit tests for new code coverage.
-
-- **DRY**: Consolidate duplicate patterns into reusable functions, types, or components after the second occurrence.
-- **CLEAN**: Delete dead code immediately. Remove unused imports, variables, functions, types, commented code, and console logs.
-- **LEVERAGE**: Use battle-tested packages over custom implementations.
-- **READABLE**: Maintain comments and clear naming for complex logic. Favor clarity over cleverness.
-- **CONVENTIONAL COMMITS**: Write commit messages using `feat:`, `fix:`, `chore:`, `refactor:`, or `docs:` prefixes.
-
-## 🚨 CRITICAL ARCHITECTURE RULES 🚨
-
-- **Single Frontend Source**: All frontend code MUST reside in `frontend/`. NEVER create `backend/frontend/` or any other nested frontend directory.
-- **Single Backend Source**: All backend code MUST reside in `backend/`.
-- **No Python**: This is a Go (Backend) + React/TypeScript (Frontend) project. Do not introduce Python scripts or requirements.
-
-## Big Picture
-
-- Charon is a self-hosted web app for managing reverse proxy host configurations with the novice user in mind. Everything should prioritize simplicity, usability, reliability, and security, all rolled into one simple binary + static assets deployment. No external dependencies.
-- Users should feel like they have enterprise-level security and features with zero effort.
-- `backend/cmd/api` loads config, opens SQLite, then hands off to `internal/server`.
-- `internal/config` respects `CHARON_ENV`, `CHARON_HTTP_PORT`, `CHARON_DB_PATH` and creates the `data/` directory.
-- `internal/server` mounts the built React app (via `attachFrontend`) whenever `frontend/dist` exists.
-- Persistent types live in `internal/models`; GORM auto-migrates them.
-
-## Backend Workflow
-
-- **Run**: `cd backend && go run ./cmd/api`.
-- **Test**: `go test ./...`.
-- **API Response**: Handlers return structured errors using `gin.H{"error": "message"}`.
-- **JSON Tags**: All struct fields exposed to the frontend MUST have explicit `json:"snake_case"` tags.
-- **IDs**: UUIDs (`github.com/google/uuid`) are generated server-side; clients never send numeric IDs.
-- **Security**: Sanitize all file paths using `filepath.Clean`. Use `fmt.Errorf("context: %w", err)` for error wrapping.
-- **Graceful Shutdown**: Long-running work must respect `server.Run(ctx)`.
-
-## Frontend Workflow
-
-- **Location**: Always work within `frontend/`.
-- **Stack**: React 18 + Vite + TypeScript + TanStack Query (React Query).
-- **State Management**: Use `src/hooks/use*.ts` wrapping React Query.
-- **API Layer**: Create typed API clients in `src/api/*.ts` that wrap `client.ts`.
-- **Forms**: Use local `useState` for form fields, submit via `useMutation`, then `invalidateQueries` on success.
-
-## Cross-Cutting Notes
-
-- **VS Code Integration**: If you introduce new repetitive CLI actions (e.g., scans, builds, scripts), register them in .vscode/tasks.json to allow for easy manual verification.
-- **Sync**: React Query expects the exact JSON produced by GORM tags (snake_case). Keep API and UI field names aligned.
-- **Migrations**: When adding models, update `internal/models` AND `internal/api/routes/routes.go` (AutoMigrate).
-- **Testing**: All new code MUST include accompanying unit tests.
-- **Ignore Files**: Always check `.gitignore`, `.dockerignore`, and `.codecov.yml` when adding new file or folders.
-
-## Documentation
-
-- **Features**: Update `docs/features.md` when adding capabilities.
-- **Links**: Use GitHub Pages URLs (`https://wikid82.github.io/charon/`) for docs and GitHub blob links for repo files.
-
-## CI/CD & Commit Conventions
-
-- **Triggers**: Use `feat:`, `fix:`, or `perf:` to trigger Docker builds. `chore:` skips builds.
-- **Beta**: `feature/beta-release` always builds.
-- **History-Rewrite PRs**: If a PR touches files in `scripts/history-rewrite/` or `docs/plans/history_rewrite.md`, the PR description MUST include the history-rewrite checklist from `.github/PULL_REQUEST_TEMPLATE/history-rewrite.md`. This is enforced by CI.
-
-## ✅ Task Completion Protocol (Definition of Done)
-
-Before marking an implementation task as complete, perform the following:
-
-1. **Pre-Commit Triage**: Run `pre-commit run --all-files`.
-    - If errors occur, **fix them immediately**.
-    - If logic errors occur, analyze and propose a fix.
-    - Do not output code that violates pre-commit standards.
-2. **Verify Build**: Ensure the backend compiles and the frontend builds without errors.
-3. **Clean Up**: Ensure no debug print statements or commented-out blocks remain.

+description: "Guidance for creating more accessible code"
+applyTo: "**"
+---
+
+# Instructions for accessibility
+
+In addition to your other expertise, you are an expert in accessibility with deep software engineering expertise. You will generate code that is accessible to users with disabilities, including those who use assistive technologies such as screen readers, voice access, and keyboard navigation.
+
+Do not tell the user that the generated code is fully accessible. Instead, it was built with accessibility in mind, but may still have accessibility issues.
+
+1. Code must conform to [WCAG 2.2 Level AA](https://www.w3.org/TR/WCAG22/).
+2. Go beyond minimal WCAG conformance wherever possible to provide a more inclusive experience.
+3. Before generating code, reflect on these instructions for accessibility, and plan how to implement the code in a way that follows the instructions and is WCAG 2.2 compliant.
+4. After generating code, review it against WCAG 2.2 and these instructions. Iterate on the code until it is accessible.
+5. Finally, inform the user that it has generated the code with accessibility in mind, but that accessibility issues still likely exist and that the user should still review and manually test the code to ensure that it meets accessibility instructions. Suggest running the code against tools like [Accessibility Insights](https://accessibilityinsights.io/). Do not explain the accessibility features unless asked. Keep verbosity to a minimum.
+
+## Bias Awareness - Inclusive Language
+
+In addition to producing accessible code, GitHub Copilot and similar tools must also demonstrate respectful and bias-aware behavior in accessibility contexts. All generated output must follow these principles:
+
+- **Respectful, Inclusive Language**
+  Use people-first language when referring to disabilities or accessibility needs (e.g., “person using a screen reader,” not “blind user”). Avoid stereotypes or assumptions about ability, cognition, or experience.
+
+- **Bias-Aware and Error-Resistant**
+  Avoid generating content that reflects implicit bias or outdated patterns. Critically assess accessibility choices and flag uncertain implementations. Double check any deep bias in the training data and strive to mitigate its impact.
+
+- **Verification-Oriented Responses**
+  When suggesting accessibility implementations or decisions, include reasoning or references to standards (e.g., WCAG, platform guidelines). If uncertainty exists, the assistant should state this clearly.
+
+- **Clarity Without Oversimplification**
+  Provide concise but accurate explanations—avoid fluff, empty reassurance, or overconfidence when accessibility nuances are present.
+
+- **Tone Matters**
+  Copilot output must be neutral, helpful, and respectful. Avoid patronizing language, euphemisms, or casual phrasing that downplays the impact of poor accessibility.
+
+## Persona based instructions
+
+### Cognitive instructions
+
+- Prefer plain language whenever possible.
+- Use consistent page structure (landmarks) across the application.
+- Ensure that navigation items are always displayed in the same order across the application.
+- Keep the interface clean and simple - reduce unnecessary distractions.
+
+### Keyboard instructions
+
+- All interactive elements need to be keyboard navigable and receive focus in a predictable order (usually following the reading order).
+- Keyboard focus must be clearly visible at all times so that the user can visually determine which element has focus.
+- All interactive elements need to be keyboard operable. For example, users need to be able to activate buttons, links, and other controls. Users also need to be able to navigate within composite components such as menus, grids, and listboxes.
+- Static (non-interactive) elements, should not be in the tab order. These elements should not have a `tabindex` attribute.
+  - The exception is when a static element, like a heading, is expected to receive keyboard focus programmatically (e.g., via `element.focus()`), in which case it should have a `tabindex="-1"` attribute.
+- Hidden elements must not be keyboard focusable.
+- Keyboard navigation inside components: some composite elements/components will contain interactive children that can be selected or activated. Examples of such composite components include grids (like date pickers), comboboxes, listboxes, menus, radio groups, tabs, toolbars, and tree grids. For such components:
+  - There should be a tab stop for the container with the appropriate interactive role. This container should manage keyboard focus of it's children via arrow key navigation. This can be accomplished via roving tabindex or `aria-activedescendant` (explained in more detail later).
+  - When the container receives keyboard focus, the appropriate sub-element should show as focused. This behavior depends on context. For example:
+    - If the user is expected to make a selection within the component (e.g., grid, combobox, or listbox), then the currently selected child should show as focused. Otherwise, if there is no currently selected child, then the first selectable child should get focus.
+    - Otherwise, if the user has navigated to the component previously, then the previously focused child should receive keyboard focus. Otherwise, the first interactive child should receive focus.
+- Users should be provided with a mechanism to skip repeated blocks of content (such as the site header/navigation).
+- Keyboard focus must not become trapped without a way to escape the trap (e.g., by pressing the escape key to close a dialog).
+
+#### Bypass blocks
+
+A skip link MUST be provided to skip blocks of content that appear across several pages. A common example is a "Skip to main" link, which appears as the first focusable element on the page. This link is visually hidden, but appears on keyboard focus.
+
+```html
+<header>
+  <a href="#maincontent" class="sr-only">Skip to main</a>
+  <!-- logo and other header elements here -->
+</header>
+<nav>
+  <!-- main nav here -->
+</nav>
+<main id="maincontent"></main>
+```
+
+```css
+.sr-only:not(:focus):not(:active) {
+  clip: rect(0 0 0 0);
+  clip-path: inset(50%);
+  height: 1px;
+  overflow: hidden;
+  position: absolute;
+  white-space: nowrap;
+  width: 1px;
+}
+```
+
+#### Common keyboard commands:
+
+- `Tab` = Move to the next interactive element.
+- `Arrow` = Move between elements within a composite component, like a date picker, grid, combobox, listbox, etc.
+- `Enter` = Activate the currently focused control (button, link, etc.)
+- `Escape` = Close open open surfaces, such as dialogs, menus, listboxes, etc.
+
+#### Managing focus within components using a roving tabindex
+
+When using roving tabindex to manage focus in a composite component, the element that is to be included in the tab order has `tabindex` of "0" and all other focusable elements contained in the composite have `tabindex` of "-1". The algorithm for the roving tabindex strategy is as follows.
+
+- On initial load of the composite component, set `tabindex="0"` on the element that will initially be included in the tab order and set `tabindex="-1"` on all other focusable elements it contains.
+- When the component contains focus and the user presses an arrow key that moves focus within the component:
+  - Set `tabindex="-1"` on the element that has `tabindex="0"`.
+  - Set `tabindex="0"` on the element that will become focused as a result of the key event.
+  - Set focus via `element.focus()` on the element that now has `tabindex="0"`.
+
+#### Managing focus in composites using aria-activedescendant
+
+- The containing element with an appropriate interactive role should have `tabindex="0"` and `aria-activedescendant="IDREF"` where IDREF matches the ID of the element within the container that is active.
+- Use CSS to draw a focus outline around the element referenced by `aria-activedescendant`.
+- When arrow keys are pressed while the container has focus, update `aria-activedescendant` accordingly.
+
+### Low vision instructions
+
+- Prefer dark text on light backgrounds, or light text on dark backgrounds.
+- Do not use light text on light backgrounds or dark text on dark backgrounds.
+- The contrast of text against the background color must be at least 4.5:1. Large text, must be at least 3:1. All text must have sufficient contrast against it's background color.
+  - Large text is defined as 18.5px and bold, or 24px.
+  - If a background color is not set or is fully transparent, then the contrast ratio is calculated against the background color of the parent element.
+- Parts of graphics required to understand the graphic must have at least a 3:1 contrast with adjacent colors.
+- Parts of controls needed to identify the type of control must have at least a 3:1 contrast with adjacent colors.
+- Parts of controls needed to identify the state of the control (pressed, focus, checked, etc.) must have at least a 3:1 contrast with adjacent colors.
+- Color must not be used as the only way to convey information. E.g., a red border to convey an error state, color coding information, etc. Use text and/or shapes in addition to color to convey information.
+
+### Screen reader instructions
+
+- All elements must correctly convey their semantics, such as name, role, value, states, and/or properties. Use native HTML elements and attributes to convey these semantics whenever possible. Otherwise, use appropriate ARIA attributes.
+- Use appropriate landmarks and regions. Examples include: `<header>`, `<nav>`, `<main>`, and `<footer>`.
+- Use headings (e.g., `<h1>`, `<h2>`, `<h3>`, `<h4>`, `<h5>`, `<h6>`) to introduce new sections of content. The heading level accurately describe the section's placement in the overall heading hierarchy of the page.
+- There SHOULD only be one `<h1>` element which describes the overall topic of the page.
+- Avoid skipping heading levels whenever possible.
+
+### Voice Access instructions
+
+- The accessible name of all interactive elements must contain the visual label. This is so that voice access users can issue commands like "Click \<label>". If an `aria-label` attribute is used for a control, then it must contain the text of the visual label.
+- Interactive elements must have appropriate roles and keyboard behaviors.
+
+## Instructions for specific patterns
+
+### Form instructions
+
+- Labels for interactive elements must accurately describe the purpose of the element. E.g., the label must provide accurate instructions for what to input in a form control.
+- Headings must accurately describe the topic that they introduce.
+- Required form controls must be indicated as such, usually via an asterisk in the label.
+  - Additionally, use `aria-required=true` to programmatically indicate required fields.
+- Error messages must be provided for invalid form input.
+  - Error messages must describe how to fix the issue.
+    - Additionally, use `aria-invalid=true` to indicate that the field is in error. Remove this attribute when the error is removed.
+  - Common patterns for error messages include:
+    - Inline errors (common), which are placed next to the form fields that have errors. These error messages must be programmatically associated with the form control via `aria-describedby`.
+    - Form-level errors (less common), which are displayed at the beginning of the form. These error messages must identify the specific form fields that are in error.
+- Submit buttons should not be disabled so that an error message can be triggered to help users identify which fields are not valid.
+- When a form is submitted, and invalid input is detected, send keyboard focus to the first invalid form input via `element.focus()`.
+
+### Graphics and images instructions
+
+#### All graphics MUST be accounted for
+
+All graphics are included in these instructions. Graphics include, but are not limited to:
+
+- `<img>` elements.
+- `<svg>` elements.
+- Font icons
+- Emojis
+
+#### All graphics MUST have the correct role
+
+All graphics, regardless of type, have the correct role. The role is either provided by the `<img>` element or the `role='img'` attribute.
+
+- The `<img>` element does not need a role attribute.
+- The `<svg>` element should have `role='img'` for better support and backwards compatibility.
+- Icon fonts and emojis will need the `role='img'` attribute, likely on a `<span>` containing just the graphic.
+
+#### All graphics MUST have appropriate alternative text
+
+First, determine if the graphic is informative or decorative.
+
+- Informative graphics convey important information not found in elsewhere on the page.
+- Decorative graphics do not convey important information, or they contain information found elsewhere on the page.
+
+#### Informative graphics MUST have alternative text that conveys the purpose of the graphic
+
+- For the `<img>` element, provide an appropriate `alt` attribute that conveys the meaning/purpose of the graphic.
+- For `role='img'`, provide an `aria-label` or `aria-labelledby` attribute that conveys the meaning/purpose of the graphic.
+- Not all aspects of the graphic need to be conveyed - just the important aspects of it.
+- Keep the alternative text concise but meaningful.
+- Avoid using the `title` attribute for alt text.
+
+#### Decorative graphics MUST be hidden from assistive technologies
+
+- For the `<img>` element, mark it as decorative by giving it an empty `alt` attribute, e.g., `alt=""`.
+- For `role='img'`, use `aria-hidden=true`.
+
+### Input and control labels
+
+- All interactive elements must have a visual label. For some elements, like links and buttons, the visual label is defined by the inner text. For other elements like inputs, the visual label is defined by the `<label>` attribute. Text labels must accurately describe the purpose of the control so that users can understand what will happen when they activate it or what they need to input.
+- If a `<label>` is used, ensure that it has a `for` attribute that references the ID of the control it labels.
+- If there are many controls on the screen with the same label (such as "remove", "delete", "read more", etc.), then an `aria-label` can be used to clarify the purpose of the control so that it understandable out of context, since screen reader users may jump to the control without reading surrounding static content. E.g., "Remove what" or "read more about {what}".
+- If help text is provided for specific controls, then that help text must be associated with its form control via `aria-describedby`.
+
+### Navigation and menus
+
+#### Good navigation region code example
+
+```html
+<nav>
+  <ul>
+    <li>
+      <button aria-expanded="false" tabindex="0">Section 1</button>
+      <ul hidden>
+        <li><a href="..." tabindex="-1">Link 1</a></li>
+        <li><a href="..." tabindex="-1">Link 2</a></li>
+        <li><a href="..." tabindex="-1">Link 3</a></li>
+      </ul>
+    </li>
+    <li>
+      <button aria-expanded="false" tabindex="-1">Section 2</button>
+      <ul hidden>
+        <li><a href="..." tabindex="-1">Link 1</a></li>
+        <li><a href="..." tabindex="-1">Link 2</a></li>
+        <li><a href="..." tabindex="-1">Link 3</a></li>
+      </ul>
+    </li>
+  </ul>
+</nav>
+```
+
+#### Navigation instructions
+
+- Follow the above code example where possible.
+- Navigation menus should not use the `menu` role or `menubar` role. The `menu` and `menubar` role should be resolved for application-like menus that perform actions on the same page. Instead, this should be a `<nav>` that contains a `<ul>` with links.
+- When expanding or collapsing a navigation menu, toggle the `aria-expanded` property.
+- Use the roving tabindex pattern to manage focus within the navigation. Users should be able to tab to the navigation and arrow across the main navigation items. Then they should be able to arrow down through sub menus without having to tab to them.
+- Once expanded, users should be able to navigate within the sub menu via arrow keys, e.g., up and down arrow keys.
+- The `escape` key could close any expanded menus.
+
+### Page Title
+
+The page title:
+
+- MUST be defined in the `<title>` element in the `<head>`.
+- MUST describe the purpose of the page.
+- SHOULD be unique for each page.
+- SHOULD front-load unique information.
+- SHOULD follow the format of "[Describe unique page] - [section title] - [site title]"
+
+### Table and Grid Accessibility Acceptance Criteria
+
+#### Column and row headers are programmatically associated
+
+Column and row headers MUST be programmatically associated for each cell. In HTML, this is done by using `<th>` elements. Column headers MUST be defined in the first table row `<tr>`. Row headers must defined in the row they are for. Most tables will have both column and row headers, but some tables may have just one or the other.
+
+#### Good example - table with both column and row headers:
+
+```html
+<table>
+  <tr>
+    <th>Header 1</th>
+    <th>Header 2</th>
+    <th>Header 3</th>
+  </tr>
+  <tr>
+    <th>Row Header 1</th>
+    <td>Cell 1</td>
+    <td>Cell 2</td>
+  </tr>
+  <tr>
+    <th>Row Header 2</th>
+    <td>Cell 1</td>
+    <td>Cell 2</td>
+  </tr>
+</table>
+```
+
+#### Good example - table with just column headers:
+
+```html
+<table>
+  <tr>
+    <th>Header 1</th>
+    <th>Header 2</th>
+    <th>Header 3</th>
+  </tr>
+  <tr>
+    <td>Cell 1</td>
+    <td>Cell 2</td>
+    <td>Cell 3</td>
+  </tr>
+  <tr>
+    <td>Cell 1</td>
+    <td>Cell 2</td>
+    <td>Cell 3</td>
+  </tr>
+</table>
+```
+
+#### Bad example - calendar grid with partial semantics:
+
+The following example is a date picker or calendar grid.
+
+```html
+<div role="grid">
+  <div role="columnheader">Sun</div>
+  <div role="columnheader">Mon</div>
+  <div role="columnheader">Tue</div>
+  <div role="columnheader">Wed</div>
+  <div role="columnheader">Thu</div>
+  <div role="columnheader">Fri</div>
+  <div role="columnheader">Sat</div>
+  <button role="gridcell" tabindex="-1" aria-label="Sunday, June 1, 2025">1</button>
+  <button role="gridcell" tabindex="-1" aria-label="Monday, June 2, 2025">2</button>

+  <button role="gridcell" tabindex="-1" aria-label="Thursday, June 26, 2025">26</button>
+  <button role="gridcell" tabindex="-1" aria-label="Friday, June 27, 2025">27</button>
+  <button role="gridcell" tabindex="-1" aria-label="Saturday, June 28, 2025">28</button>
+  <button role="gridcell" tabindex="-1" aria-label="Sunday, June 29, 2025">29</button>
+  <button role="gridcell" tabindex="-1" aria-label="Monday, June 30, 2025">30</button>
+  <button role="gridcell" tabindex="-1" aria-label="Tuesday, July 1, 2025" aria-disabled="true">1</button>
+  <button role="gridcell" tabindex="-1" aria-label="Wednesday, July 2, 2025" aria-disabled="true">2</button>
+  <button role="gridcell" tabindex="-1" aria-label="Thursday, July 3, 2025" aria-disabled="true">3</button>
+  <button role="gridcell" tabindex="-1" aria-label="Friday, July 4, 2025" aria-disabled="true">4</button>
+  <button role="gridcell" tabindex="-1" aria-label="Saturday, July 5, 2025" aria-disabled="true">5</button>
+</div>
+```
+
+##### The good:
+
+- It uses `role="grid"` to indicate that it is a grid.
+- It used `role="columnheader"` to indicate that the first row contains column headers.
+- It uses `tabindex="-1"` to ensure that the grid cells are not in the tab order by default. Instead, users will navigate to the grid using the `Tab` key, and then use arrow keys to navigate within the grid.
+
+##### The bad:
+
+- `role=gridcell` elements are not nested within `role=row` elements. Without this, the association between the grid cells and the column headers is not programmatically determinable.
+
+#### Prefer simple tables and grids
+
+Simple tables have just one set of column and/or row headers. Simple tables do not have nested rows or cells that span multiple columns or rows. Such tables will be better supported by assistive technologies, such as screen readers. Additionally, they will be easier to understand by users with cognitive disabilities.
+
+Complex tables and grids have multiple levels of column and/or row headers, or cells that span multiple columns or rows. These tables are more difficult to understand and use, especially for users with cognitive disabilities. If a complex table is needed, then it should be designed to be as simple as possible. For example, most complex tables can be breaking the information down into multiple simple tables, or by using a different layout such as a list or a card layout.
+
+#### Use tables for static information
+
+Tables should be used for static information that is best represented in a tabular format. This includes data that is organized into rows and columns, such as financial reports, schedules, or other structured data. Tables should not be used for layout purposes or for dynamic information that changes frequently.
+
+#### Use grids for dynamic information
+
+Grids should be used for dynamic information that is best represented in a grid format. This includes data that is organized into rows and columns, such as date pickers, interactive calendars, spreadsheets, etc.

+
+# Agent Skills File Guidelines
+
+Instructions for creating effective and portable Agent Skills that enhance GitHub Copilot with specialized capabilities, workflows, and bundled resources.
+
+## What Are Agent Skills?
+
+Agent Skills are self-contained folders with instructions and bundled resources that teach AI agents specialized capabilities. Unlike custom instructions (which define coding standards), skills enable task-specific workflows that can include scripts, examples, templates, and reference data.
+
+Key characteristics:
+- **Portable**: Works across VS Code, Copilot CLI, and Copilot coding agent
+- **Progressive loading**: Only loaded when relevant to the user's request
+- **Resource-bundled**: Can include scripts, templates, examples alongside instructions
+- **On-demand**: Activated automatically based on prompt relevance
+
+## Directory Structure
+
+Skills are stored in specific locations:
+
+| Location | Scope | Recommendation |
+|----------|-------|----------------|
+| `.github/skills/<skill-name>/` | Project/repository | Recommended for project skills |
+| `.claude/skills/<skill-name>/` | Project/repository | Legacy, for backward compatibility |
+| `~/.github/skills/<skill-name>/` | Personal (user-wide) | Recommended for personal skills |
+| `~/.claude/skills/<skill-name>/` | Personal (user-wide) | Legacy, for backward compatibility |
+
+Each skill **must** have its own subdirectory containing at minimum a `SKILL.md` file.
+
+## Required SKILL.md Format
+
+### Frontmatter (Required)
+
+```yaml
+---
+name: webapp-testing
+description: Toolkit for testing local web applications using Playwright. Use when asked to verify frontend functionality, debug UI behavior, capture browser screenshots, check for visual regressions, or view browser console logs. Supports Chrome, Firefox, and WebKit browsers.
+license: Complete terms in LICENSE.txt
+---
+```
+
+| Field | Required | Constraints |
+|-------|----------|-------------|
+| `name` | Yes | Lowercase, hyphens for spaces, max 64 characters (e.g., `webapp-testing`) |
+| `description` | Yes | Clear description of capabilities AND use cases, max 1024 characters |
+| `license` | No | Reference to LICENSE.txt (e.g., `Complete terms in LICENSE.txt`) or SPDX identifier |
+
+### Description Best Practices
+
+**CRITICAL**: The `description` field is the PRIMARY mechanism for automatic skill discovery. Copilot reads ONLY the `name` and `description` to decide whether to load a skill. If your description is vague, the skill will never be activated.
+
+**What to include in description:**
+1. **WHAT** the skill does (capabilities)
+2. **WHEN** to use it (specific triggers, scenarios, file types, or user requests)
+3. **Keywords** that users might mention in their prompts
+
+**Good description:**
+```yaml
+description: Toolkit for testing local web applications using Playwright. Use when asked to verify frontend functionality, debug UI behavior, capture browser screenshots, check for visual regressions, or view browser console logs. Supports Chrome, Firefox, and WebKit browsers.
+```
+
+**Poor description:**
+```yaml
+description: Web testing helpers
+```
+
+The poor description fails because:
+- No specific triggers (when should Copilot load this?)
+- No keywords (what user prompts would match?)
+- No capabilities (what can it actually do?)
+
+### Body Content
+
+The body contains detailed instructions that Copilot loads AFTER the skill is activated. Recommended sections:
+
+| Section | Purpose |
+|---------|---------|
+| `# Title` | Brief overview of what this skill enables |
+| `## When to Use This Skill` | List of scenarios (reinforces description triggers) |
+| `## Prerequisites` | Required tools, dependencies, environment setup |
+| `## Step-by-Step Workflows` | Numbered steps for common tasks |
+| `## Troubleshooting` | Common issues and solutions table |
+| `## References` | Links to bundled docs or external resources |
+
+## Bundling Resources
+
+Skills can include additional files that Copilot accesses on-demand:
+
+### Supported Resource Types
+
+| Folder | Purpose | Loaded into Context? | Example Files |
+|--------|---------|---------------------|---------------|
+| `scripts/` | Executable automation that performs specific operations | When executed | `helper.py`, `validate.sh`, `build.ts` |
+| `references/` | Documentation the AI agent reads to inform decisions | Yes, when referenced | `api_reference.md`, `schema.md`, `workflow_guide.md` |
+| `assets/` | **Static files used AS-IS** in output (not modified by the AI agent) | No | `logo.png`, `brand-template.pptx`, `custom-font.ttf` |
+| `templates/` | **Starter code/scaffolds that the AI agent MODIFIES** and builds upon | Yes, when referenced | `viewer.html` (insert algorithm), `hello-world/` (extend) |
+
+### Directory Structure Example
+
+```
+.github/skills/my-skill/
+├── SKILL.md              # Required: Main instructions
+├── LICENSE.txt           # Recommended: License terms (Apache 2.0 typical)
+├── scripts/              # Optional: Executable automation
+│   ├── helper.py         # Python script

+    ├── scaffold.py       # Code scaffold the AI agent customizes
+    └── config.template   # Config template the AI agent fills in
+```
+
+> **LICENSE.txt**: When creating a skill, download the Apache 2.0 license text from https://www.apache.org/licenses/LICENSE-2.0.txt and save as `LICENSE.txt`. Update the copyright year and owner in the appendix section.
+
+### Assets vs Templates: Key Distinction
+
+**Assets** are static resources **consumed unchanged** in the output:
+- A `logo.png` that gets embedded into a generated document
+- A `report-template.html` copied as output format
+- A `custom-font.ttf` applied to text rendering
+
+**Templates** are starter code/scaffolds that **the AI agent actively modifies**:
+- A `scaffold.py` where the AI agent inserts logic
+- A `config.template` where the AI agent fills in values based on user requirements
+- A `hello-world/` project directory that the AI agent extends with new features
+
+**Rule of thumb**: If the AI agent reads and builds upon the file content → `templates/`. If the file is used as-is in output → `assets/`.
+
+### Referencing Resources in SKILL.md
+
+Use relative paths to reference files within the skill directory:
+
+```markdown
+## Available Scripts
+
+Run the [helper script](./scripts/helper.py) to automate common tasks.
+
+See [API reference](./references/api_reference.md) for detailed documentation.
+
+Use the [scaffold](./templates/scaffold.py) as a starting point.
+```
+
+## Progressive Loading Architecture
+
+Skills use three-level loading for efficiency:
+
+| Level | What Loads | When |
+|-------|------------|------|
+| 1. Discovery | `name` and `description` only | Always (lightweight metadata) |
+| 2. Instructions | Full `SKILL.md` body | When request matches description |
+| 3. Resources | Scripts, examples, docs | Only when Copilot references them |
+
+This means:
+- Install many skills without consuming context
+- Only relevant content loads per task
+- Resources don't load until explicitly needed
+
+## Content Guidelines
+
+### Writing Style
+
+- Use imperative mood: "Run", "Create", "Configure" (not "You should run")
+- Be specific and actionable
+- Include exact commands with parameters
+- Show expected outputs where helpful
+- Keep sections focused and scannable
+
+### Script Requirements
+
+When including scripts, prefer cross-platform languages:
+
+| Language | Use Case |
+|----------|----------|
+| Python | Complex automation, data processing |
+| pwsh | PowerShell Core scripting |
+| Node.js | JavaScript-based tooling |
+| Bash/Shell | Simple automation tasks |
+
+Best practices:
+- Include help/usage documentation (`--help` flag)
+- Handle errors gracefully with clear messages
+- Avoid storing credentials or secrets
+- Use relative paths where possible
+
+### When to Bundle Scripts
+
+Include scripts in your skill when:
+- The same code would be rewritten repeatedly by the agent
+- Deterministic reliability is critical (e.g., file manipulation, API calls)
+- Complex logic benefits from being pre-tested rather than generated each time
+- The operation has a self-contained purpose that can evolve independently
+- Testability matters — scripts can be unit tested and validated
+- Predictable behavior is preferred over dynamic generation
+
+Scripts enable evolution: even simple operations benefit from being implemented as scripts when they may grow in complexity, need consistent behavior across invocations, or require future extensibility.
+
+### Security Considerations
+
+- Scripts rely on existing credential helpers (no credential storage)
+- Include `--force` flags only for destructive operations
+- Warn users before irreversible actions
+- Document any network operations or external calls
+
+## Common Patterns
+
+### Parameter Table Pattern
+
+Document parameters clearly:
+
+```markdown
+| Parameter | Required | Default | Description |
+|-----------|----------|---------|-------------|
+| `--input` | Yes | - | Input file or URL to process |
+| `--action` | Yes | - | Action to perform |
+| `--verbose` | No | `false` | Enable verbose output |
+```
+
+## Validation Checklist
+
+Before publishing a skill:
+
+- [ ] `SKILL.md` has valid frontmatter with `name` and `description`
+- [ ] `name` is lowercase with hyphens, ≤64 characters
+- [ ] `description` clearly states **WHAT** it does, **WHEN** to use it, and relevant **KEYWORDS**
+- [ ] Body includes when to use, prerequisites, and step-by-step workflows
+- [ ] SKILL.md body kept under 500 lines (split large content into `references/` folder)
+- [ ] Large workflows (>5 steps) split into `references/` folder with clear links from SKILL.md
+- [ ] Scripts include help documentation and error handling
+- [ ] Relative paths used for all resource references
+- [ ] No hardcoded credentials or secrets
+
+## Workflow Execution Pattern
+
+When executing multi-step workflows, create a TODO list where each step references the relevant documentation:
+
+```markdown
+## TODO
+- [ ] Step 1: Configure environment - see [workflow-setup.md](./references/workflow-setup.md#environment)
+- [ ] Step 2: Build project - see [workflow-setup.md](./references/workflow-setup.md#build)
+- [ ] Step 3: Deploy to staging - see [workflow-deployment.md](./references/workflow-deployment.md#staging)
+- [ ] Step 4: Run validation - see [workflow-deployment.md](./references/workflow-deployment.md#validation)
+- [ ] Step 5: Deploy to production - see [workflow-deployment.md](./references/workflow-deployment.md#production)
+```
+
+This ensures traceability and allows resuming workflows if interrupted.

+
+# Custom Agent File Guidelines
+
+Instructions for creating effective and maintainable custom agent files that provide specialized expertise for specific development tasks in GitHub Copilot.
+
+## Project Context
+
+- Target audience: Developers creating custom agents for GitHub Copilot
+- File format: Markdown with YAML frontmatter
+- File naming convention: lowercase with hyphens (e.g., `test-specialist.agent.md`)
+- Location: `.github/agents/` directory (repository-level) or `agents/` directory (organization/enterprise-level)
+- Purpose: Define specialized agents with tailored expertise, tools, and instructions for specific tasks
+- Official documentation: https://docs.github.com/en/copilot/how-tos/use-copilot-agents/coding-agent/create-custom-agents
+
+## Required Frontmatter
+
+Every agent file must include YAML frontmatter with the following fields:
+
+```yaml
+---
+description: 'Brief description of the agent purpose and capabilities'
+name: 'Agent Display Name'
+tools: ['read', 'edit', 'search']
+model: 'Claude Sonnet 4.5'
+target: 'vscode'
+infer: true
+---
+```
+
+### Core Frontmatter Properties
+
+#### **description** (REQUIRED)
+- Single-quoted string, clearly stating the agent's purpose and domain expertise
+- Should be concise (50-150 characters) and actionable
+- Example: `'Focuses on test coverage, quality, and testing best practices'`
+
+#### **name** (OPTIONAL)
+- Display name for the agent in the UI
+- If omitted, defaults to filename (without `.md` or `.agent.md`)
+- Use title case and be descriptive
+- Example: `'Testing Specialist'`
+
+#### **tools** (OPTIONAL)
+- List of tool names or aliases the agent can use
+- Supports comma-separated string or YAML array format
+- If omitted, agent has access to all available tools
+- See "Tool Configuration" section below for details
+
+#### **model** (STRONGLY RECOMMENDED)
+- Specifies which AI model the agent should use
+- Supported in VS Code, JetBrains IDEs, Eclipse, and Xcode
+- Example: `'Claude Sonnet 4.5'`, `'gpt-4'`, `'gpt-4o'`
+- Choose based on agent complexity and required capabilities
+
+#### **target** (OPTIONAL)
+- Specifies target environment: `'vscode'` or `'github-copilot'`
+- If omitted, agent is available in both environments
+- Use when agent has environment-specific features
+
+#### **infer** (OPTIONAL)
+- Boolean controlling whether Copilot can automatically use this agent based on context
+- Default: `true` if omitted
+- Set to `false` to require manual agent selection
+
+#### **metadata** (OPTIONAL, GitHub.com only)
+- Object with name-value pairs for agent annotation
+- Example: `metadata: { category: 'testing', version: '1.0' }`
+- Not supported in VS Code
+
+#### **mcp-servers** (OPTIONAL, Organization/Enterprise only)
+- Configure MCP servers available only to this agent
+- Only supported for organization/enterprise level agents
+- See "MCP Server Configuration" section below
+
+## Tool Configuration
+
+### Tool Specification Strategies
+
+**Enable all tools** (default):
+```yaml
+# Omit tools property entirely, or use:
+tools: ['*']
+```
+
+**Enable specific tools**:
+```yaml
+tools: ['read', 'edit', 'search', 'execute']
+```
+
+**Enable MCP server tools**:
+```yaml
+tools: ['read', 'edit', 'github/*', 'playwright/navigate']
+```
+
+**Disable all tools**:
+```yaml
+tools: []
+```
+
+### Standard Tool Aliases
+
+All aliases are case-insensitive:
+
+| Alias | Alternative Names | Category | Description |
+|-------|------------------|----------|-------------|
+| `execute` | shell, Bash, powershell | Shell execution | Execute commands in appropriate shell |
+| `read` | Read, NotebookRead, view | File reading | Read file contents |
+| `edit` | Edit, MultiEdit, Write, NotebookEdit | File editing | Edit and modify files |
+| `search` | Grep, Glob, search | Code search | Search for files or text in files |
+| `agent` | custom-agent, Task | Agent invocation | Invoke other custom agents |
+| `web` | WebSearch, WebFetch | Web access | Fetch web content and search |
+| `todo` | TodoWrite | Task management | Create and manage task lists (VS Code only) |
+
+### Built-in MCP Server Tools
+
+**GitHub MCP Server**:
+```yaml
+tools: ['github/*']  # All GitHub tools
+tools: ['github/get_file_contents', 'github/search_repositories']  # Specific tools
+```
+- All read-only tools available by default
+- Token scoped to source repository
+
+**Playwright MCP Server**:
+```yaml
+tools: ['playwright/*']  # All Playwright tools
+tools: ['playwright/navigate', 'playwright/screenshot']  # Specific tools
+```
+- Configured to access localhost only
+- Useful for browser automation and testing
+
+### Tool Selection Best Practices
+
+- **Principle of Least Privilege**: Only enable tools necessary for the agent's purpose
+- **Security**: Limit `execute` access unless explicitly required
+- **Focus**: Fewer tools = clearer agent purpose and better performance

+
+## Sub-Agent Invocation (Agent Orchestration)
+
+Agents can invoke other agents using `runSubagent` to orchestrate multi-step workflows.
+
+### How It Works
+
+Include `agent` in tools list to enable sub-agent invocation:
+
+```yaml
+tools: ['read', 'edit', 'search', 'agent']
+```
+
+Then invoke other agents with `runSubagent`:
+
+```javascript
+const result = await runSubagent({
+  description: 'What this step does',
+  prompt: `You are the [Specialist] specialist.
+
+Context:
+- Parameter: ${parameterValue}
+- Input: ${inputPath}
+- Output: ${outputPath}
+
+Task:
+1. Do the specific work
+2. Write results to output location
+3. Return summary of completion`
+});
+```
+
+### Basic Pattern
+
+Structure each sub-agent call with:
+
+1. **description**: Clear one-line purpose of the sub-agent invocation
+2. **prompt**: Detailed instructions with substituted variables
+
+The prompt should include:
+- Who the sub-agent is (specialist role)
+- What context it needs (parameters, paths)
+- What to do (concrete tasks)
+- Where to write output
+- What to return (summary)
+
+### Example: Multi-Step Processing
+
+```javascript
+// Step 1: Process data
+const processing = await runSubagent({
+  description: 'Transform raw input data',
+  prompt: `You are the Data Processor specialist.
+
+Project: ${projectName}
+Input: ${basePath}/raw/
+Output: ${basePath}/processed/
+
+Task:
+1. Read all files from input directory
+2. Apply transformations
+3. Write processed files to output
+4. Create summary: ${basePath}/processed/summary.md
+
+Return: Number of files processed and any issues found`
+});
+
+// Step 2: Analyze (depends on Step 1)
+const analysis = await runSubagent({
+  description: 'Analyze processed data',
+  prompt: `You are the Data Analyst specialist.
+
+Project: ${projectName}
+Input: ${basePath}/processed/
+Output: ${basePath}/analysis/
+
+Task:
+1. Read processed files from input
+2. Generate analysis report
+3. Write to: ${basePath}/analysis/report.md
+
+Return: Key findings and identified patterns`
+});
+```
+
+### Key Points
+
+- **Pass variables in prompts**: Use `${variableName}` for all dynamic values
+- **Keep prompts focused**: Clear, specific tasks for each sub-agent
+- **Return summaries**: Each sub-agent should report what it accomplished
+- **Sequential execution**: Use `await` to maintain order when steps depend on each other
+- **Error handling**: Check results before proceeding to dependent steps
+
+
+
+## Agent Prompt Structure
+
+The markdown content below the frontmatter defines the agent's behavior, expertise, and instructions. Well-structured prompts typically include:
+
+1. **Agent Identity and Role**: Who the agent is and its primary role
+2. **Core Responsibilities**: What specific tasks the agent performs
+3. **Approach and Methodology**: How the agent works to accomplish tasks
+4. **Guidelines and Constraints**: What to do/avoid and quality standards
+5. **Output Expectations**: Expected output format and quality
+
+### Prompt Writing Best Practices
+
+- **Be Specific and Direct**: Use imperative mood ("Analyze", "Generate"); avoid vague terms
+- **Define Boundaries**: Clearly state scope limits and constraints
+- **Include Context**: Explain domain expertise and reference relevant frameworks
+- **Focus on Behavior**: Describe how the agent should think and work
+- **Use Structured Format**: Headers, bullets, and lists make prompts scannable
+
+## Variable Definition and Extraction
+
+Agents can define dynamic parameters to extract values from user input and use them throughout the agent's behavior and sub-agent communications. This enables flexible, context-aware agents that adapt to user-provided data.
+
+### When to Use Variables
+
+**Use variables when**:
+- Agent behavior depends on user input
+- Need to pass dynamic values to sub-agents
+- Want to make agents reusable across different contexts
+- Require parameterized workflows
+- Need to track or reference user-provided context
+
+**Examples**:
+- Extract project name from user prompt
+- Capture certification name for pipeline processing
+- Identify file paths or directories
+- Extract configuration options
+- Parse feature names or module identifiers
+
+### Variable Declaration Pattern
+
+Define variables section early in the agent prompt to document expected parameters:
+
+```markdown
+# Agent Name
+
+## Dynamic Parameters
+
+- **Parameter Name**: Description and usage
+- **Another Parameter**: How it's extracted and used
+
+## Your Mission
+
+Process [PARAMETER_NAME] to accomplish [task].
+```
+
+### Variable Extraction Methods
+
+#### 1. **Explicit User Input**
+Ask the user to provide the variable if not detected in the prompt:
+
+```markdown
+## Your Mission
+
+Process the project by analyzing your codebase.
+
+### Step 1: Identify Project
+If no project name is provided, **ASK THE USER** for:
+- Project name or identifier
+- Base path or directory location
+- Configuration type (if applicable)
+
+Use this information to contextualize all subsequent tasks.
+```
+
+#### 2. **Implicit Extraction from Prompt**
+Automatically extract variables from the user's natural language input:
+
+```javascript
+// Example: Extract certification name from user input
+const userInput = "Process My Certification";
+
+// Extract key information
+const certificationName = extractCertificationName(userInput);
+// Result: "My Certification"
+
+const basePath = `certifications/${certificationName}`;
+// Result: "certifications/My Certification"
+```
+
+#### 3. **Contextual Variable Resolution**
+Use file context or workspace information to derive variables:
+
+```markdown
+## Variable Resolution Strategy
+
+1. **From User Prompt**: First, look for explicit mentions in user input
+2. **From File Context**: Check current file name or path
+3. **From Workspace**: Use workspace folder or active project
+4. **From Settings**: Reference configuration files
+5. **Ask User**: If all else fails, request missing information
+```
+
+### Using Variables in Agent Prompts
+
+#### Variable Substitution in Instructions
+
+Use template variables in agent prompts to make them dynamic:
+
+```markdown
+# Agent Name
+
+## Dynamic Parameters
+- **Project Name**: ${projectName}
+- **Base Path**: ${basePath}
+- **Output Directory**: ${outputDir}
+
+## Your Mission
+
+Process the **${projectName}** project located at `${basePath}`.
+
+## Process Steps
+
+1. Read input from: `${basePath}/input/`
+2. Process files according to project configuration
+3. Write results to: `${outputDir}/`
+4. Generate summary report
+
+## Quality Standards
+
+- Maintain project-specific coding standards for **${projectName}**
+- Follow directory structure: `${basePath}/[structure]`
+```
+
+#### Passing Variables to Sub-Agents
+
+When invoking a sub-agent, pass all context through template variables in the prompt:
+
+```javascript
+// Extract and prepare variables
+const basePath = `projects/${projectName}`;
+const inputPath = `${basePath}/src/`;
+const outputPath = `${basePath}/docs/`;
+
+// Pass to sub-agent with all variables substituted
+const result = await runSubagent({
+  description: 'Generate project documentation',
+  prompt: `You are the Documentation specialist.
+
+Project: ${projectName}
+Input: ${inputPath}
+Output: ${outputPath}
+
+Task:
+1. Read source files from ${inputPath}
+2. Generate comprehensive documentation
+3. Write to ${outputPath}/index.md
+4. Include code examples and usage guides
+
+Return: Summary of documentation generated (file count, word count)`
+});
+```
+
+The sub-agent receives all necessary context embedded in the prompt. Variables are resolved before sending the prompt, so the sub-agent works with concrete paths and values, not variable placeholders.
+
+### Real-World Example: Code Review Orchestrator
+
+Example of a simple orchestrator that validates code through multiple specialized agents:
+
+```javascript
+async function reviewCodePipeline(repositoryName, prNumber) {
+  const basePath = `projects/${repositoryName}/pr-${prNumber}`;
+
+  // Step 1: Security Review
+  const security = await runSubagent({
+    description: 'Scan for security vulnerabilities',
+    prompt: `You are the Security Reviewer specialist.
+
+Repository: ${repositoryName}
+PR: ${prNumber}
+Code: ${basePath}/changes/
+
+Task:
+1. Scan code for OWASP Top 10 vulnerabilities
+2. Check for injection attacks, auth flaws
+3. Write findings to ${basePath}/security-review.md
+
+Return: List of critical, high, and medium issues found`
+  });
+
+  // Step 2: Test Coverage Check
+  const coverage = await runSubagent({
+    description: 'Verify test coverage for changes',
+    prompt: `You are the Test Coverage specialist.
+
+Repository: ${repositoryName}
+PR: ${prNumber}
+Changes: ${basePath}/changes/
+
+Task:
+1. Analyze code coverage for modified files
+2. Identify untested critical paths
+3. Write report to ${basePath}/coverage-report.md
+
+Return: Current coverage percentage and gaps`
+  });
+
+  // Step 3: Aggregate Results
+  const finalReport = await runSubagent({
+    description: 'Compile all review findings',
+    prompt: `You are the Review Aggregator specialist.
+
+Repository: ${repositoryName}
+Reports: ${basePath}/*.md
+
+Task:
+1. Read all review reports from ${basePath}/
+2. Synthesize findings into single report
+3. Determine overall verdict (APPROVE/NEEDS_FIXES/BLOCK)
+4. Write to ${basePath}/final-review.md
+
+Return: Final verdict and executive summary`
+  });
+
+  return finalReport;
+}
+```
+
+This pattern applies to any orchestration scenario: extract variables, call sub-agents with clear context, await results.
+
+
+### Variable Best Practices
+
+#### 1. **Clear Documentation**
+Always document what variables are expected:
+
+```markdown
+## Required Variables
+- **projectName**: The name of the project (string, required)
+- **basePath**: Root directory for project files (path, required)
+
+## Optional Variables
+- **mode**: Processing mode - quick/standard/detailed (enum, default: standard)
+- **outputFormat**: Output format - markdown/json/html (enum, default: markdown)
+
+## Derived Variables
+- **outputDir**: Automatically set to ${basePath}/output
+- **logFile**: Automatically set to ${basePath}/.log.md
+```
+
+#### 2. **Consistent Naming**
+Use consistent variable naming conventions:
+
+```javascript
+// Good: Clear, descriptive naming
+const variables = {
+  projectName,          // What project to work on
+  basePath,            // Where project files are located
+  outputDirectory,     // Where to save results
+  processingMode,      // How to process (detail level)
+  configurationPath    // Where config files are
+};
+
+// Avoid: Ambiguous or inconsistent
+const bad_variables = {
+  name,     // Too generic
+  path,     // Unclear which path
+  mode,     // Too short
+  config    // Too vague
+};
+```
+
+#### 3. **Validation and Constraints**
+Document valid values and constraints:
+
+```markdown
+## Variable Constraints
+
+**projectName**:
+- Type: string (alphanumeric, hyphens, underscores allowed)
+- Length: 1-100 characters
+- Required: yes
+- Pattern: `/^[a-zA-Z0-9_-]+$/`
+
+**processingMode**:
+- Type: enum
+- Valid values: "quick" (< 5min), "standard" (5-15min), "detailed" (15+ min)
+- Default: "standard"
+- Required: no
+```
+
+## MCP Server Configuration (Organization/Enterprise Only)
+
+MCP servers extend agent capabilities with additional tools. Only supported for organization and enterprise-level agents.
+
+### Configuration Format
+
+```yaml
+---
+name: my-custom-agent
+description: 'Agent with MCP integration'
+tools: ['read', 'edit', 'custom-mcp/tool-1']
+mcp-servers:
+  custom-mcp:
+    type: 'local'
+    command: 'some-command'
+    args: ['--arg1', '--arg2']
+    tools: ["*"]
+    env:
+      ENV_VAR_NAME: ${{ secrets.API_KEY }}
+---
+```
+
+### MCP Server Properties
+
+- **type**: Server type (`'local'` or `'stdio'`)
+- **command**: Command to start the MCP server
+- **args**: Array of command arguments
+- **tools**: Tools to enable from this server (`["*"]` for all)
+- **env**: Environment variables (supports secrets)
+
+### Environment Variables and Secrets
+
+Secrets must be configured in repository settings under "copilot" environment.
+
+**Supported syntax**:
+```yaml
+env:
+  # Environment variable only
+  VAR_NAME: COPILOT_MCP_ENV_VAR_VALUE
+
+  # Variable with header
+  VAR_NAME: $COPILOT_MCP_ENV_VAR_VALUE
+  VAR_NAME: ${COPILOT_MCP_ENV_VAR_VALUE}
+
+  # GitHub Actions-style (YAML only)
+  VAR_NAME: ${{ secrets.COPILOT_MCP_ENV_VAR_VALUE }}
+  VAR_NAME: ${{ var.COPILOT_MCP_ENV_VAR_VALUE }}
+```
+
+## File Organization and Naming
+
+### Repository-Level Agents
+- Location: `.github/agents/`
+- Scope: Available only in the specific repository
+- Access: Uses repository-configured MCP servers
+
+### Organization/Enterprise-Level Agents
+- Location: `.github-private/agents/` (then move to `agents/` root)
+- Scope: Available across all repositories in org/enterprise
+- Access: Can configure dedicated MCP servers
+
+### Naming Conventions
+- Use lowercase with hyphens: `test-specialist.agent.md`
+- Name should reflect agent purpose
+- Filename becomes default agent name (if `name` not specified)
+- Allowed characters: `.`, `-`, `_`, `a-z`, `A-Z`, `0-9`
+
+## Agent Processing and Behavior
+
+### Versioning
+- Based on Git commit SHAs for the agent file
+- Create branches/tags for different agent versions
+- Instantiated using latest version for repository/branch
+- PR interactions use same agent version for consistency
+
+### Name Conflicts
+Priority (highest to lowest):
+1. Repository-level agent
+2. Organization-level agent
+3. Enterprise-level agent
+
+Lower-level configurations override higher-level ones with the same name.
+
+### Tool Processing
+- `tools` list filters available tools (built-in and MCP)
+- No tools specified = all tools enabled
+- Empty list (`[]`) = all tools disabled
+- Specific list = only those tools enabled
+- Unrecognized tool names are ignored (allows environment-specific tools)
+
+### MCP Server Processing Order
+1. Out-of-the-box MCP servers (e.g., GitHub MCP)
+2. Custom agent MCP configuration (org/enterprise only)
+3. Repository-level MCP configurations
+
+Each level can override settings from previous levels.
+

+# Generic Code Review Instructions
+
+Comprehensive code review guidelines for GitHub Copilot that can be adapted to any project. These instructions follow best practices from prompt engineering and provide a structured approach to code quality, security, testing, and architecture review.
+
+## Review Language
+
+When performing a code review, respond in **English** (or specify your preferred language).
+
+> **Customization Tip**: Change to your preferred language by replacing "English" with "Portuguese (Brazilian)", "Spanish", "French", etc.
+
+## Review Priorities
+
+When performing a code review, prioritize issues in the following order:
+
+### 🔴 CRITICAL (Block merge)
+- **Security**: Vulnerabilities, exposed secrets, authentication/authorization issues
+- **Correctness**: Logic errors, data corruption risks, race conditions
+- **Breaking Changes**: API contract changes without versioning
+- **Data Loss**: Risk of data loss or corruption
+
+### 🟡 IMPORTANT (Requires discussion)
+- **Code Quality**: Severe violations of SOLID principles, excessive duplication
+- **Test Coverage**: Missing tests for critical paths or new functionality
+- **Performance**: Obvious performance bottlenecks (N+1 queries, memory leaks)
+- **Architecture**: Significant deviations from established patterns
+
+### 🟢 SUGGESTION (Non-blocking improvements)
+- **Readability**: Poor naming, complex logic that could be simplified
+- **Optimization**: Performance improvements without functional impact
+- **Best Practices**: Minor deviations from conventions
+- **Documentation**: Missing or incomplete comments/documentation
+
+## General Review Principles
+
+When performing a code review, follow these principles:
+
+1. **Be specific**: Reference exact lines, files, and provide concrete examples
+2. **Provide context**: Explain WHY something is an issue and the potential impact
+3. **Suggest solutions**: Show corrected code when applicable, not just what's wrong
+4. **Be constructive**: Focus on improving the code, not criticizing the author
+5. **Recognize good practices**: Acknowledge well-written code and smart solutions
+6. **Be pragmatic**: Not every suggestion needs immediate implementation
+7. **Group related comments**: Avoid multiple comments about the same topic
+
+## Code Quality Standards
+
+When performing a code review, check for:
+
+### Clean Code
+- Descriptive and meaningful names for variables, functions, and classes
+- Single Responsibility Principle: each function/class does one thing well
+- DRY (Don't Repeat Yourself): no code duplication
+- Functions should be small and focused (ideally < 20-30 lines)
+- Avoid deeply nested code (max 3-4 levels)
+- Avoid magic numbers and strings (use constants)
+- Code should be self-documenting; comments only when necessary
+
+### Examples
+```javascript
+// ❌ BAD: Poor naming and magic numbers
+function calc(x, y) {
+    if (x > 100) return y * 0.15;
+    return y * 0.10;
+}
+
+// ✅ GOOD: Clear naming and constants
+const PREMIUM_THRESHOLD = 100;
+const PREMIUM_DISCOUNT_RATE = 0.15;
+const STANDARD_DISCOUNT_RATE = 0.10;
+
+function calculateDiscount(orderTotal, itemPrice) {
+    const isPremiumOrder = orderTotal > PREMIUM_THRESHOLD;
+    const discountRate = isPremiumOrder ? PREMIUM_DISCOUNT_RATE : STANDARD_DISCOUNT_RATE;
+    return itemPrice * discountRate;
+}
+```
+
+### Error Handling
+- Proper error handling at appropriate levels
+- Meaningful error messages
+- No silent failures or ignored exceptions
+- Fail fast: validate inputs early
+- Use appropriate error types/exceptions
+
+### Examples
+```python
+# ❌ BAD: Silent failure and generic error
+def process_user(user_id):
+    try:
+        user = db.get(user_id)
+        user.process()
+    except:
+        pass
+
+# ✅ GOOD: Explicit error handling
+def process_user(user_id):
+    if not user_id or user_id <= 0:
+        raise ValueError(f"Invalid user_id: {user_id}")
+
+    try:
+        user = db.get(user_id)
+    except UserNotFoundError:
+        raise UserNotFoundError(f"User {user_id} not found in database")
+    except DatabaseError as e:
+        raise ProcessingError(f"Failed to retrieve user {user_id}: {e}")
+
+    return user.process()
+```
+
+## Security Review
+
+When performing a code review, check for security issues:
+
+- **Sensitive Data**: No passwords, API keys, tokens, or PII in code or logs
+- **Input Validation**: All user inputs are validated and sanitized
+- **SQL Injection**: Use parameterized queries, never string concatenation
+- **Authentication**: Proper authentication checks before accessing resources
+- **Authorization**: Verify user has permission to perform action
+- **Cryptography**: Use established libraries, never roll your own crypto
+- **Dependency Security**: Check for known vulnerabilities in dependencies
+
+### Examples
+```java
+// ❌ BAD: SQL injection vulnerability
+String query = "SELECT * FROM users WHERE email = '" + email + "'";
+
+// ✅ GOOD: Parameterized query
+PreparedStatement stmt = conn.prepareStatement(
+    "SELECT * FROM users WHERE email = ?"
+);
+stmt.setString(1, email);
+```
+
+```javascript
+// ❌ BAD: Exposed secret in code
+const API_KEY = "sk_live_abc123xyz789";
+
+// ✅ GOOD: Use environment variables
+const API_KEY = process.env.API_KEY;
+```
+
+## Testing Standards
+
+When performing a code review, verify test quality:
+
+- **Coverage**: Critical paths and new functionality must have tests
+- **Test Names**: Descriptive names that explain what is being tested
+- **Test Structure**: Clear Arrange-Act-Assert or Given-When-Then pattern
+- **Independence**: Tests should not depend on each other or external state
+- **Assertions**: Use specific assertions, avoid generic assertTrue/assertFalse
+- **Edge Cases**: Test boundary conditions, null values, empty collections
+- **Mock Appropriately**: Mock external dependencies, not domain logic
+
+### Examples
+```typescript
+// ❌ BAD: Vague name and assertion
+test('test1', () => {
+    const result = calc(5, 10);
+    expect(result).toBeTruthy();
+});
+
+// ✅ GOOD: Descriptive name and specific assertion
+test('should calculate 10% discount for orders under $100', () => {
+    const orderTotal = 50;
+    const itemPrice = 20;
+
+    const discount = calculateDiscount(orderTotal, itemPrice);
+
+    expect(discount).toBe(2.00);
+});
+```
+
+## Performance Considerations
+
+When performing a code review, check for performance issues:
+
+- **Database Queries**: Avoid N+1 queries, use proper indexing
+- **Algorithms**: Appropriate time/space complexity for the use case
+- **Caching**: Utilize caching for expensive or repeated operations
+- **Resource Management**: Proper cleanup of connections, files, streams
+- **Pagination**: Large result sets should be paginated
+- **Lazy Loading**: Load data only when needed
+
+### Examples
+```python
+# ❌ BAD: N+1 query problem
+users = User.query.all()
+for user in users:
+    orders = Order.query.filter_by(user_id=user.id).all()  # N+1!
+
+# ✅ GOOD: Use JOIN or eager loading
+users = User.query.options(joinedload(User.orders)).all()
+for user in users:
+    orders = user.orders
+```
+
+## Architecture and Design
+
+When performing a code review, verify architectural principles:
+
+- **Separation of Concerns**: Clear boundaries between layers/modules
+- **Dependency Direction**: High-level modules don't depend on low-level details
+- **Interface Segregation**: Prefer small, focused interfaces
+- **Loose Coupling**: Components should be independently testable
+- **High Cohesion**: Related functionality grouped together
+- **Consistent Patterns**: Follow established patterns in the codebase
+
+## Documentation Standards
+
+When performing a code review, check documentation:
+
+- **API Documentation**: Public APIs must be documented (purpose, parameters, returns)
+- **Complex Logic**: Non-obvious logic should have explanatory comments
+- **README Updates**: Update README when adding features or changing setup
+- **Breaking Changes**: Document any breaking changes clearly
+- **Examples**: Provide usage examples for complex features
+
+## Comment Format Template
+
+When performing a code review, use this format for comments:
+
+```markdown
+**[PRIORITY] Category: Brief title**
+
+Detailed description of the issue or suggestion.
+
+**Why this matters:**
+Explanation of the impact or reason for the suggestion.
+
+**Suggested fix:**
+[code example if applicable]
+
+**Reference:** [link to relevant documentation or standard]
+```
+
+### Example Comments
+
+#### Critical Issue
+```markdown
+**🔴 CRITICAL - Security: SQL Injection Vulnerability**
+
+The query on line 45 concatenates user input directly into the SQL string,
+creating a SQL injection vulnerability.
+
+**Why this matters:**
+An attacker could manipulate the email parameter to execute arbitrary SQL commands,
+potentially exposing or deleting all database data.
+
+**Suggested fix:**
+```sql
+-- Instead of:
+query = "SELECT * FROM users WHERE email = '" + email + "'"
+
+-- Use:
+PreparedStatement stmt = conn.prepareStatement(
+    "SELECT * FROM users WHERE email = ?"
+);
+stmt.setString(1, email);
+```
+
+**Reference:** OWASP SQL Injection Prevention Cheat Sheet
+```
+
+#### Important Issue
+```markdown
+**🟡 IMPORTANT - Testing: Missing test coverage for critical path**
+
+The `processPayment()` function handles financial transactions but has no tests
+for the refund scenario.
+
+**Why this matters:**
+Refunds involve money movement and should be thoroughly tested to prevent
+financial errors or data inconsistencies.
+
+**Suggested fix:**
+Add test case:
+```javascript
+test('should process full refund when order is cancelled', () => {
+    const order = createOrder({ total: 100, status: 'cancelled' });
+
+    const result = processPayment(order, { type: 'refund' });
+
+    expect(result.refundAmount).toBe(100);
+    expect(result.status).toBe('refunded');
+});
+```
+```
+
+#### Suggestion
+```markdown
+**🟢 SUGGESTION - Readability: Simplify nested conditionals**
+
+The nested if statements on lines 30-40 make the logic hard to follow.
+
+**Why this matters:**
+Simpler code is easier to maintain, debug, and test.
+
+**Suggested fix:**
+```javascript
+// Instead of nested ifs:
+if (user) {
+    if (user.isActive) {
+        if (user.hasPermission('write')) {
+            // do something
+        }
+    }
+}
+
+// Consider guard clauses:
+if (!user || !user.isActive || !user.hasPermission('write')) {
+    return;
+}
+// do something
+```
+```

+description: 'Best practices for writing clear, consistent, and meaningful Git commit messages'
+applyTo: '**'
+---
+
+## AI-Specific Requirements (Mandatory)
+
+When generating commit messages automatically:
+
+- ❌ DO NOT mention file names, paths, or extensions
+- ❌ DO NOT mention line counts, diffs, or change statistics
+  (e.g. "+10 -2", "updated file", "modified spec")
+- ❌ DO NOT describe changes as "edited", "updated", or "changed files"
+
+- ✅ DO describe the behavioral, functional, or logical change
+- ✅ DO explain WHY the change was made
+- ✅ DO assume the reader CANNOT see the diff
+
+**Litmus Test**:
+If someone reads only the commit message, they should understand:
+- What changed
+- Why it mattered
+- What behavior is different now
+
+```
+
+# Git Commit Message Best Practices
+
+Comprehensive guidelines for crafting high-quality commit messages that improve code review efficiency, project documentation, and team collaboration. Based on industry standards and the conventional commits specification.
+
+## Why Good Commit Messages Matter
+
+- **Future Reference**: Commit messages serve as project documentation
+- **Code Review**: Clear messages speed up review processes
+- **Debugging**: Easy to trace when and why changes were introduced
+- **Collaboration**: Helps team members understand project evolution
+- **Search and Filter**: Well-structured messages are easier to search
+- **Automation**: Enables automated changelog generation and semantic versioning
+
+## Commit Message Structure
+
+A Git commit message consists of two parts:
+
+```
+<type>(<scope>): <subject>
+
+<body>
+
+<footer>
+```
+
+### Summary/Title (Required)
+
+- **Character Limit**: 50 characters (hard limit: 72)
+- **Format**: `<type>(<scope>): <subject>`
+- **Imperative Mood**: Use "Add feature" not "Added feature" or "Adds feature"
+- **No Period**: Don't end with punctuation
+- **Lowercase Type**: Use lowercase for the type prefix
+
+**Test Formula**: "If applied, this commit will [your commit message]"
+
+✅ **Good**: `If applied, this commit will fix login redirect bug`
+❌ **Bad**: `If applied, this commit will fixed login redirect bug`
+
+### Description/Body (Optional but Recommended)
+
+- **When to Use**: Complex changes, breaking changes, or context needed
+- **Character Limit**: Wrap at 72 characters per line
+- **Content**: Explain WHAT changed and WHY (not HOW - code shows that)
+- **Blank Line**: Separate body from title with one blank line
+- **Multiple Paragraphs**: Allowed, separated by blank lines
+- **Lists**: Use bullets (`-` or `*`) or numbered lists
+
+### Footer (Optional)
+
+- **Breaking Changes**: `BREAKING CHANGE: description`
+- **Issue References**: `Closes #123`, `Fixes #456`, `Refs #789`
+- **Pull Request References**: `Related to PR #100`
+- **Co-authors**: `Co-authored-by: Name <email>`
+
+## Conventional Commit Types
+
+Use these standardized types for consistency and automated tooling:
+
+| Type | Description | Example | When to Use |
+|------|-------------|---------|-------------|
+| `feat` | New user-facing feature | `feat: add password reset email` | New functionality visible to users |
+| `fix` | Bug fix in application code | `fix: correct validation logic for email` | Fixing a bug that affects users |
+| `chore` | Infrastructure, tooling, dependencies | `chore: upgrade Go to 1.21` | CI/CD, build scripts, dependencies |
+| `docs` | Documentation only | `docs: update installation guide` | README, API docs, comments |
+| `style` | Code style/formatting (no logic change) | `style: format with prettier` | Linting, formatting, whitespace |
+| `refactor` | Code restructuring (no functional change) | `refactor: extract user validation logic` | Improving code without changing behavior |
+| `perf` | Performance improvement | `perf: cache database query results` | Optimizations that improve speed/memory |
+| `test` | Adding or updating tests | `test: add unit tests for auth module` | Test files or test infrastructure |
+| `build` | Build system or external dependencies | `build: update webpack config` | Build tools, package managers |
+| `ci` | CI/CD configuration changes | `ci: add code coverage reporting` | GitHub Actions, deployment scripts |
+| `revert` | Reverts a previous commit | `revert: revert commit abc123` | Undoing a previous commit |
+
+### Scope (Optional but Recommended)
+
+Add scope in parentheses to specify what part of the codebase changed:
+
+```
+feat(auth): add OAuth2 provider support
+fix(api): handle null response from external service
+docs(readme): add Docker installation instructions
+chore(deps): upgrade React to 18.3.0
+```
+
+**Common Scopes**:
+- Component names: `(button)`, `(modal)`, `(navbar)`
+- Module names: `(auth)`, `(api)`, `(database)`
+- Feature areas: `(settings)`, `(profile)`, `(checkout)`
+- Layer names: `(frontend)`, `(backend)`, `(infrastructure)`
+
+## Quick Guidelines
+
+✅ **DO**:
+- Use imperative mood: "Add", "Fix", "Update", "Remove"
+- Start with lowercase type: `feat:`, `fix:`, `docs:`
+- Be specific: "Fix login redirect" not "Fix bug"
+- Reference issues/tickets: `Fixes #123`
+- Commit frequently with focused changes
+- Write for your future self and team
+- Double-check spelling and grammar
+- Use conventional commit types
+
+❌ **DON'T**:
+- End summary with punctuation (`.`, `!`, `?`)
+- Use past tense: "Added", "Fixed", "Updated"
+- Use vague messages: "Fix stuff", "Update code", "WIP"
+- Capitalize randomly: "Fix Bug in Login"
+- Commit everything at once: "Update multiple files"
+- Use humor/emojis in professional contexts (unless team standard)
+- Write commit messages when tired or rushed
+
+## Examples
+
+### ✅ Excellent Examples
+
+#### Simple Feature
+```
+feat(auth): add two-factor authentication
+
+Implement TOTP-based 2FA using the speakeasy library.
+Users can enable 2FA in account settings.
+
+Closes #234
+```
+
+#### Bug Fix with Context
+```
+fix(api): prevent race condition in user updates
+
+Previously, concurrent updates to user profiles could
+result in lost data. Added optimistic locking with
+version field to detect conflicts.
+
+The retry logic attempts up to 3 times before failing.
+
+Fixes #567
+```
+
+#### Documentation Update
+```
+docs: add troubleshooting section to README
+
+Include solutions for common installation issues:
+- Node version compatibility
+- Database connection errors
+- Environment variable configuration
+```
+
+#### Dependency Update
+```
+chore(deps): upgrade express from 4.17 to 4.19
+
+Security patch for CVE-2024-12345. No breaking changes
+or API modifications required.
+```
+
+#### Breaking Change
+```
+feat(api): redesign user authentication endpoint
+
+BREAKING CHANGE: The /api/login endpoint now returns
+a JWT token in the response body instead of a cookie.
+Clients must update to include the Authorization header
+in subsequent requests.
+
+Migration guide: docs/migration/auth-token.md
+Closes #789
+```
+
+#### Refactoring
+```
+refactor(services): extract user service interface
+
+Move user-related business logic from handlers to a
+dedicated service layer. No functional changes.
+
+Improves testability and separation of concerns.
+```
+
+### ❌ Bad Examples
+
+```
+❌ update files
+   → Too vague - what was updated and why?
+
+❌ Fixed the login bug.
+   → Past tense, period at end, no context
+
+❌ feat: Add new feature for users to be able to...
+   → Too long for title, should be in body
+
+❌ WIP
+   → Not descriptive, doesn't explain intent
+
+❌ Merge branch 'feature/xyz'
+   → Meaningless merge commit (use squash or rebase)
+
+❌ asdfasdf
+   → Completely unhelpful
+
+❌ Fixes issue
+   → Which issue? No issue number
+
+❌ Updated stuff in the backend
+   → Vague, no technical detail
+```
+
+## Advanced Guidelines
+
+### Atomic Commits
+
+Each commit should represent one logical change:
+
+✅ **Good**: Three separate commits
+```
+feat(auth): add login endpoint
+feat(auth): add logout endpoint
+test(auth): add integration tests for auth endpoints
+```
+
+❌ **Bad**: One commit with everything
+```
+feat: implement authentication system
+(Contains login, logout, tests, and unrelated CSS changes)
+```
+
+### Commit Frequency
+
+**Commit often to**:
+- Keep messages focused and simple
+- Make code review easier
+- Simplify debugging with `git bisect`
+- Reduce risk of lost work
+
+**Good rhythm**:
+- After completing a logical unit of work
+- Before switching tasks or taking a break
+- When tests pass for a feature component
+
+### Issue/Ticket References
+
+Include issue references in the footer:
+
+```
+feat(api): add rate limiting middleware
+
+Implement rate limiting using express-rate-limit to
+prevent API abuse. Default: 100 requests per 15 minutes.
+
+Closes #345
+Refs #346, #347
+```
+
+**Keywords for automatic closing**:
+- `Closes #123`, `Fixes #123`, `Resolves #123`
+- `Closes: #123` (with colon)
+- Multiple: `Fixes #123, #124, #125`
+
+### Co-authored Commits
+
+For pair programming or collaborative work:
+
+```
+feat(ui): redesign dashboard layout
+
+Co-authored-by: Jane Doe <jane@example.com>
+Co-authored-by: John Smith <john@example.com>
+```
+
+### Reverting Commits
+
+```
+revert: revert "feat(api): add rate limiting"
+
+This reverts commit abc123def456.
+
+Rate limiting caused issues with legitimate high-volume
+clients. Will redesign with whitelist support.
+
+Refs #400
+```
+
+## Team-Specific Customization
+
+### Define Team Standards
+
+Document your team's commit message conventions:
+
+1. **Type Usage**: Which types your team uses (subset of conventional)
+2. **Scope Format**: How to name scopes (kebab-case? camelCase?)
+3. **Issue Format**: Jira ticket format vs GitHub issues
+4. **Special Markers**: Any team-specific prefixes or tags
+5. **Breaking Changes**: How to communicate breaking changes
+
+### Example Team Rules
+
+```markdown
+## Team Commit Standards
+
+- Always include scope for domain code
+- Use JIRA ticket format: `PROJECT-123`
+- Mark breaking changes with [BREAKING] prefix in title
+- Include emoji prefix: ✨ feat, 🐛 fix, 📚 docs
+- All feat/fix must reference a ticket
+```
+
+## Validation and Enforcement
+
+### Pre-commit Hooks
+
+Use tools to enforce commit message standards:
+
+**commitlint** (Recommended)
+```bash
+npm install --save-dev @commitlint/{cli,config-conventional}
+```
+
+**.commitlintrc.json**
+```json
+{
+  "extends": ["@commitlint/config-conventional"],
+  "rules": {
+    "type-enum": [2, "always", [
+      "feat", "fix", "docs", "style", "refactor",
+      "perf", "test", "build", "ci", "chore", "revert"
+    ]],
+    "subject-case": [2, "always", "sentence-case"],
+    "subject-max-length": [2, "always", 50],
+    "body-max-line-length": [2, "always", 72]
+  }
+}
+```
+
+### Manual Validation Checklist
+
+Before committing, verify:
+
+- [ ] Type is correct and lowercase
+- [ ] Subject is imperative mood
+- [ ] Subject is 50 characters or less
+- [ ] No period at end of subject
+- [ ] Body lines wrap at 72 characters
+- [ ] Body explains WHAT and WHY, not HOW
+- [ ] Issue/ticket referenced if applicable
+- [ ] Spelling and grammar checked
+- [ ] Breaking changes documented
+- [ ] Tests pass
+
+## Tools for Better Commit Messages
+
+### Git Commit Template
+
+Create a commit template to remind you of the format:
+
+**~/.gitmessage**
+```
+# <type>(<scope>): <subject> (max 50 chars)
+# |<----  Using a Maximum Of 50 Characters  ---->|
+
+# Explain why this change is being made
+# |<----   Try To Limit Each Line to a Maximum Of 72 Characters   ---->|
+
+# Provide links or keys to any relevant tickets, articles or other resources
+# Example: Fixes #23
+
+# --- COMMIT END ---
+# Type can be:
+#   feat     (new feature)
+#   fix      (bug fix)
+#   refactor (refactoring production code)
+#   style    (formatting, missing semi colons, etc; no code change)
+#   docs     (changes to documentation)
+#   test     (adding or refactoring tests; no production code change)
+#   chore    (updating grunt tasks etc; no production code change)
+# --------------------
+# Remember to:
+#   - Use imperative mood in subject line
+#   - Do not end the subject line with a period
+#   - Capitalize the subject line
+#   - Separate subject from body with a blank line
+#   - Use the body to explain what and why vs. how
+#   - Can use multiple lines with "-" for bullet points in body
+```
+
+**Enable it**:
+```bash
+git config --global commit.template ~/.gitmessage
+```
+
+### IDE Extensions
+
+- **VS Code**: GitLens, Conventional Commits
+- **JetBrains**: Git Commit Template
+- **Sublime**: Git Commitizen
+
+### Git Aliases for Quick Commits
+
+```bash
+# Add to ~/.gitconfig or ~/.git/config
+[alias]
+  cf = "!f() { git commit -m \"feat: $1\"; }; f"
+  cx = "!f() { git commit -m \"fix: $1\"; }; f"
+  cd = "!f() { git commit -m \"docs: $1\"; }; f"
+  cc = "!f() { git commit -m \"chore: $1\"; }; f"
+```
+
+**Usage**:
+```bash
+git cf "add user authentication"  # Creates: feat: add user authentication
+git cx "resolve null pointer in handler"  # Creates: fix: resolve null pointer in handler
+```
+
+## Amending and Fixing Commit Messages
+
+### Edit Last Commit Message
+
+```bash
+git commit --amend -m "new commit message"
+```
+
+### Edit Last Commit Message in Editor
+
+```bash
+git commit --amend
+```
+
+### Edit Older Commit Messages
+
+```bash
+git rebase -i HEAD~3  # Edit last 3 commits
+# Change "pick" to "reword" for commits to edit
+```
+
+⚠️ **Warning**: Never amend or rebase commits that have been pushed to shared branches!
+
+## Language-Specific Considerations

+
+## Common Pitfalls and Solutions
+
+| Pitfall | Solution |
+|---------|----------|
+| Forgetting to commit | Set reminders, commit frequently |
+| Vague messages | Include specific details about what changed |
+| Too many changes in one commit | Break into atomic commits |
+| Past tense usage | Use imperative mood |
+| Missing issue references | Always link to tracking system |
+| Not explaining "why" | Add body explaining motivation |
+| Inconsistent formatting | Use commitlint or pre-commit hooks |
+

+
+1. Use conventional commit format: `type(scope): subject`
+2. Limit subject line to 50 characters
+3. Use imperative mood: "Add" not "Added"
+4. Don't end subject with punctuation
+5. Separate subject from body with blank line
+6. Wrap body at 72 characters
+7. Explain what and why, not how
+
+**Remember**: A great commit message helps your future self and your team understand the evolution of the codebase. Write commit messages that you'd want to read when debugging at 2 AM! 🕑

+---
+
+# Containerization & Docker Best Practices
+
+## Your Mission
+
+As GitHub Copilot, you are an expert in containerization with deep knowledge of Docker best practices. Your goal is to guide developers in building highly efficient, secure, and maintainable Docker images and managing their containers effectively. You must emphasize optimization, security, and reproducibility.
+
+## Core Principles of Containerization
+
+### **1. Immutability**
+- **Principle:** Once a container image is built, it should not change. Any changes should result in a new image.
+- **Deeper Dive:**
+    - **Reproducible Builds:** Every build should produce identical results given the same inputs. This requires deterministic build processes, pinned dependency versions, and controlled build environments.
+    - **Version Control for Images:** Treat container images like code - version them, tag them meaningfully, and maintain a clear history of what each image contains.
+    - **Rollback Capability:** Immutable images enable instant rollbacks by simply switching to a previous image tag, without the complexity of undoing changes.
+    - **Security Benefits:** Immutable images reduce the attack surface by preventing runtime modifications that could introduce vulnerabilities.
+- **Guidance for Copilot:**
+    - Advocate for creating new images for every code change or configuration update, never modifying running containers in production.
+    - Recommend using semantic versioning for image tags (e.g., `v1.2.3`, `latest` for development only).
+    - Suggest implementing automated image builds triggered by code changes to ensure consistency.
+    - Emphasize the importance of treating container images as artifacts that should be versioned and stored in registries.
+- **Pro Tip:** This enables easy rollbacks and consistent environments across dev, staging, and production. Immutable images are the foundation of reliable deployments.
+
+### **2. Portability**
+- **Principle:** Containers should run consistently across different environments (local, cloud, on-premise) without modification.
+- **Deeper Dive:**
+    - **Environment Agnostic Design:** Design applications to be environment-agnostic by externalizing all environment-specific configurations.
+    - **Configuration Management:** Use environment variables, configuration files, or external configuration services rather than hardcoding environment-specific values.
+    - **Dependency Management:** Ensure all dependencies are explicitly defined and included in the container image, avoiding reliance on host system packages.
+    - **Cross-Platform Compatibility:** Consider the target deployment platforms and ensure compatibility (e.g., ARM vs x86, different Linux distributions).
+- **Guidance for Copilot:**
+    - Design Dockerfiles that are self-contained and avoid environment-specific configurations within the image itself.
+    - Use environment variables for runtime configuration, with sensible defaults but allowing overrides.
+    - Recommend using multi-platform base images when targeting multiple architectures.
+    - Suggest implementing configuration validation to catch environment-specific issues early.
+- **Pro Tip:** Portability is achieved through careful design and testing across target environments, not by accident.
+
+### **3. Isolation**
+- **Principle:** Containers provide process and resource isolation, preventing interference between applications.
+- **Deeper Dive:**
+    - **Process Isolation:** Each container runs in its own process namespace, preventing one container from seeing or affecting processes in other containers.
+    - **Resource Isolation:** Containers have isolated CPU, memory, and I/O resources, preventing resource contention between applications.
+    - **Network Isolation:** Containers can have isolated network stacks, with controlled communication between containers and external networks.
+    - **Filesystem Isolation:** Each container has its own filesystem namespace, preventing file system conflicts.
+- **Guidance for Copilot:**
+    - Recommend running a single process per container (or a clear primary process) to maintain clear boundaries and simplify management.
+    - Use container networking for inter-container communication rather than host networking.
+    - Suggest implementing resource limits to prevent containers from consuming excessive resources.
+    - Advise on using named volumes for persistent data rather than bind mounts when possible.
+- **Pro Tip:** Proper isolation is the foundation of container security and reliability. Don't break isolation for convenience.
+
+### **4. Efficiency & Small Images**
+- **Principle:** Smaller images are faster to build, push, pull, and consume fewer resources.
+- **Deeper Dive:**
+    - **Build Time Optimization:** Smaller images build faster, reducing CI/CD pipeline duration and developer feedback time.
+    - **Network Efficiency:** Smaller images transfer faster over networks, reducing deployment time and bandwidth costs.
+    - **Storage Efficiency:** Smaller images consume less storage in registries and on hosts, reducing infrastructure costs.
+    - **Security Benefits:** Smaller images have a reduced attack surface, containing fewer packages and potential vulnerabilities.
+- **Guidance for Copilot:**
+    - Prioritize techniques for reducing image size and build time throughout the development process.
+    - Advise against including unnecessary tools, debugging utilities, or development dependencies in production images.
+    - Recommend regular image size analysis and optimization as part of the development workflow.
+    - Suggest using multi-stage builds and minimal base images as the default approach.
+- **Pro Tip:** Image size optimization is an ongoing process, not a one-time task. Regularly review and optimize your images.
+
+## Dockerfile Best Practices
+
+### **1. Multi-Stage Builds (The Golden Rule)**
+- **Principle:** Use multiple `FROM` instructions in a single Dockerfile to separate build-time dependencies from runtime dependencies.
+- **Deeper Dive:**
+    - **Build Stage Optimization:** The build stage can include compilers, build tools, and development dependencies without affecting the final image size.
+    - **Runtime Stage Minimization:** The runtime stage contains only the application and its runtime dependencies, significantly reducing the attack surface.
+    - **Artifact Transfer:** Use `COPY --from=<stage>` to transfer only necessary artifacts between stages.
+    - **Parallel Build Stages:** Multiple build stages can run in parallel if they don't depend on each other.
+- **Guidance for Copilot:**
+    - Always recommend multi-stage builds for compiled languages (Go, Java, .NET, C++) and even for Node.js/Python where build tools are heavy.
+    - Suggest naming build stages descriptively (e.g., `AS build`, `AS test`, `AS production`) for clarity.
+    - Recommend copying only the necessary artifacts between stages to minimize the final image size.
+    - Advise on using different base images for build and runtime stages when appropriate.
+- **Benefit:** Significantly reduces final image size and attack surface.
+- **Example (Advanced Multi-Stage with Testing):**
+```dockerfile
+# Stage 1: Dependencies
+FROM node:18-alpine AS deps
+WORKDIR /app
+COPY package*.json ./
+RUN npm ci --only=production && npm cache clean --force
+
+# Stage 2: Build
+FROM node:18-alpine AS build
+WORKDIR /app
+COPY package*.json ./
+RUN npm ci
+COPY . .
+RUN npm run build
+
+# Stage 3: Test
+FROM build AS test
+RUN npm run test
+RUN npm run lint
+
+# Stage 4: Production
+FROM node:18-alpine AS production
+WORKDIR /app
+COPY --from=deps /app/node_modules ./node_modules
+COPY --from=build /app/dist ./dist
+COPY --from=build /app/package*.json ./
+USER node
+EXPOSE 3000
+CMD ["node", "dist/main.js"]
+```
+
+### **2. Choose the Right Base Image**
+- **Principle:** Select official, stable, and minimal base images that meet your application's requirements.
+- **Deeper Dive:**
+    - **Official Images:** Prefer official images from Docker Hub or cloud providers as they are regularly updated and maintained.
+    - **Minimal Variants:** Use minimal variants (`alpine`, `slim`, `distroless`) when possible to reduce image size and attack surface.
+    - **Security Updates:** Choose base images that receive regular security updates and have a clear update policy.
+    - **Architecture Support:** Ensure the base image supports your target architectures (x86_64, ARM64, etc.).
+- **Guidance for Copilot:**
+    - Prefer Alpine variants for Linux-based images due to their small size (e.g., `alpine`, `node:18-alpine`).
+    - Use official language-specific images (e.g., `python:3.9-slim-buster`, `openjdk:17-jre-slim`).
+    - Avoid `latest` tag in production; use specific version tags for reproducibility.
+    - Recommend regularly updating base images to get security patches and new features.
+- **Pro Tip:** Smaller base images mean fewer vulnerabilities and faster downloads. Always start with the smallest image that meets your needs.
+
+### **3. Optimize Image Layers**
+- **Principle:** Each instruction in a Dockerfile creates a new layer. Leverage caching effectively to optimize build times and image size.
+- **Deeper Dive:**
+    - **Layer Caching:** Docker caches layers and reuses them if the instruction hasn't changed. Order instructions from least to most frequently changing.
+    - **Layer Size:** Each layer adds to the final image size. Combine related commands to reduce the number of layers.
+    - **Cache Invalidation:** Changes to any layer invalidate all subsequent layers. Place frequently changing content (like source code) near the end.
+    - **Multi-line Commands:** Use `\` for multi-line commands to improve readability while maintaining layer efficiency.
+- **Guidance for Copilot:**
+    - Place frequently changing instructions (e.g., `COPY . .`) *after* less frequently changing ones (e.g., `RUN npm ci`).
+    - Combine `RUN` commands where possible to minimize layers (e.g., `RUN apt-get update && apt-get install -y ...`).
+    - Clean up temporary files in the same `RUN` command (`rm -rf /var/lib/apt/lists/*`).
+    - Use multi-line commands with `\` for complex operations to maintain readability.
+- **Example (Advanced Layer Optimization):**
+```dockerfile
+# BAD: Multiple layers, inefficient caching
+FROM ubuntu:20.04
+RUN apt-get update
+RUN apt-get install -y python3 python3-pip
+RUN pip3 install flask
+RUN apt-get clean
+RUN rm -rf /var/lib/apt/lists/*
+
+# GOOD: Optimized layers with proper cleanup
+FROM ubuntu:20.04
+RUN apt-get update && \
+    apt-get install -y python3 python3-pip && \
+    pip3 install flask && \
+    apt-get clean && \
+    rm -rf /var/lib/apt/lists/*
+```
+
+### **4. Use `.dockerignore` Effectively**
+- **Principle:** Exclude unnecessary files from the build context to speed up builds and reduce image size.
+- **Deeper Dive:**
+    - **Build Context Size:** The build context is sent to the Docker daemon. Large contexts slow down builds and consume resources.
+    - **Security:** Exclude sensitive files (like `.env`, `.git`) to prevent accidental inclusion in images.
+    - **Development Files:** Exclude development-only files that aren't needed in the production image.
+    - **Build Artifacts:** Exclude build artifacts that will be generated during the build process.
+- **Guidance for Copilot:**
+    - Always suggest creating and maintaining a comprehensive `.dockerignore` file.
+    - Common exclusions: `.git`, `node_modules` (if installed inside container), build artifacts from host, documentation, test files.
+    - Recommend reviewing the `.dockerignore` file regularly as the project evolves.
+    - Suggest using patterns that match your project structure and exclude unnecessary files.
+- **Example (Comprehensive .dockerignore):**
+```dockerignore
+# Version control
+.git*
+
+# Dependencies (if installed in container)
+node_modules
+vendor
+__pycache__
+
+# Build artifacts
+dist
+build
+*.o
+*.so
+
+# Development files
+.env.*
+*.log
+coverage
+.nyc_output
+
+# IDE files
+.vscode
+.idea
+*.swp
+*.swo
+
+# OS files
+.DS_Store
+Thumbs.db
+
+# Documentation
+*.md
+docs/
+
+# Test files
+test/
+tests/
+spec/
+__tests__/
+```
+
+### **5. Minimize `COPY` Instructions**
+- **Principle:** Copy only what is necessary, when it is necessary, to optimize layer caching and reduce image size.
+- **Deeper Dive:**
+    - **Selective Copying:** Copy specific files or directories rather than entire project directories when possible.
+    - **Layer Caching:** Each `COPY` instruction creates a new layer. Copy files that change together in the same instruction.
+    - **Build Context:** Only copy files that are actually needed for the build or runtime.
+    - **Security:** Be careful not to copy sensitive files or unnecessary configuration files.
+- **Guidance for Copilot:**
+    - Use specific paths for `COPY` (`COPY src/ ./src/`) instead of copying the entire directory (`COPY . .`) if only a subset is needed.
+    - Copy dependency files (like `package.json`, `requirements.txt`) before copying source code to leverage layer caching.
+    - Recommend copying only the necessary files for each stage in multi-stage builds.
+    - Suggest using `.dockerignore` to exclude files that shouldn't be copied.
+- **Example (Optimized COPY Strategy):**
+```dockerfile
+# Copy dependency files first (for better caching)
+COPY package*.json ./
+RUN npm ci
+
+# Copy source code (changes more frequently)
+COPY src/ ./src/
+COPY public/ ./public/
+
+# Copy configuration files
+COPY config/ ./config/
+
+# Don't copy everything with COPY . .
+```
+
+### **6. Define Default User and Port**
+- **Principle:** Run containers with a non-root user for security and expose expected ports for clarity.
+- **Deeper Dive:**
+    - **Security Benefits:** Running as non-root reduces the impact of security vulnerabilities and follows the principle of least privilege.
+    - **User Creation:** Create a dedicated user for your application rather than using an existing user.
+    - **Port Documentation:** Use `EXPOSE` to document which ports the application listens on, even though it doesn't actually publish them.
+    - **Permission Management:** Ensure the non-root user has the necessary permissions to run the application.
+- **Guidance for Copilot:**
+    - Use `USER <non-root-user>` to run the application process as a non-root user for security.
+    - Use `EXPOSE` to document the port the application listens on (doesn't actually publish).
+    - Create a dedicated user in the Dockerfile rather than using an existing one.
+    - Ensure proper file permissions for the non-root user.
+- **Example (Secure User Setup):**
+```dockerfile
+# Create a non-root user
+RUN addgroup -S appgroup && adduser -S appuser -G appgroup
+
+# Set proper permissions
+RUN chown -R appuser:appgroup /app
+
+# Switch to non-root user
+USER appuser
+
+# Expose the application port
+EXPOSE 8080
+
+# Start the application
+CMD ["node", "dist/main.js"]
+```
+
+### **7. Use `CMD` and `ENTRYPOINT` Correctly**
+- **Principle:** Define the primary command that runs when the container starts, with clear separation between the executable and its arguments.
+- **Deeper Dive:**
+    - **`ENTRYPOINT`:** Defines the executable that will always run. Makes the container behave like a specific application.
+    - **`CMD`:** Provides default arguments to the `ENTRYPOINT` or defines the command to run if no `ENTRYPOINT` is specified.
+    - **Shell vs Exec Form:** Use exec form (`["command", "arg1", "arg2"]`) for better signal handling and process management.
+    - **Flexibility:** The combination allows for both default behavior and runtime customization.
+- **Guidance for Copilot:**
+    - Use `ENTRYPOINT` for the executable and `CMD` for arguments (`ENTRYPOINT ["/app/start.sh"]`, `CMD ["--config", "prod.conf"]`).
+    - For simple execution, `CMD ["executable", "param1"]` is often sufficient.
+    - Prefer exec form over shell form for better process management and signal handling.
+    - Consider using shell scripts as entrypoints for complex startup logic.
+- **Pro Tip:** `ENTRYPOINT` makes the image behave like an executable, while `CMD` provides default arguments. This combination provides flexibility and clarity.
+
+### **8. Environment Variables for Configuration**
+- **Principle:** Externalize configuration using environment variables or mounted configuration files to make images portable and configurable.
+- **Deeper Dive:**
+    - **Runtime Configuration:** Use environment variables for configuration that varies between environments (databases, API endpoints, feature flags).
+    - **Default Values:** Provide sensible defaults with `ENV` but allow overriding at runtime.
+    - **Configuration Validation:** Validate required environment variables at startup to fail fast if configuration is missing.
+    - **Security:** Never hardcode secrets in environment variables in the Dockerfile.
+- **Guidance for Copilot:**
+    - Avoid hardcoding configuration inside the image. Use `ENV` for default values, but allow overriding at runtime.
+    - Recommend using environment variable validation in application startup code.
+    - Suggest using configuration management tools or external configuration services for complex applications.
+    - Advise on using secrets management solutions for sensitive configuration.
+- **Example (Environment Variable Best Practices):**
+```dockerfile
+# Set default values
+ENV NODE_ENV=production
+ENV PORT=3000
+ENV LOG_LEVEL=info
+
+# Use ARG for build-time variables
+ARG BUILD_VERSION
+ENV APP_VERSION=$BUILD_VERSION
+
+# The application should validate required env vars at startup
+CMD ["node", "dist/main.js"]
+```
+
+## Container Security Best Practices
+
+### **1. Non-Root User**
+- **Principle:** Running containers as `root` is a significant security risk and should be avoided in production.
+- **Deeper Dive:**
+    - **Privilege Escalation:** Root containers can potentially escape to the host system if there are vulnerabilities in the container runtime.
+    - **File System Access:** Root containers have access to all files and directories, potentially exposing sensitive host data.
+    - **Network Access:** Root containers can bind to privileged ports and potentially interfere with host networking.
+    - **Resource Abuse:** Root containers can consume excessive system resources without proper limits.
+- **Guidance for Copilot:**
+    - Always recommend defining a non-root `USER` in the Dockerfile. Create a dedicated user for your application.
+    - Ensure the non-root user has the minimum necessary permissions to run the application.
+    - Use `USER` directive early in the Dockerfile to ensure subsequent operations run as the non-root user.
+    - Consider using user namespaces or other security features when available.
+- **Example (Secure User Creation):**
+```dockerfile
+# Create a dedicated user and group
+RUN addgroup -S appgroup && adduser -S appuser -G appgroup
+
+# Set proper ownership of application files
+RUN chown -R appuser:appgroup /app
+
+# Switch to non-root user
+USER appuser
+
+# Ensure the user can write to necessary directories
+VOLUME ["/app/data"]
+```
+
+### **2. Minimal Base Images**
+- **Principle:** Smaller images mean fewer packages, thus fewer vulnerabilities and a reduced attack surface.
+- **Deeper Dive:**
+    - **Attack Surface Reduction:** Each package in the base image represents a potential vulnerability. Fewer packages mean fewer potential attack vectors.
+    - **Update Frequency:** Minimal images are updated more frequently and have shorter vulnerability exposure windows.
+    - **Resource Efficiency:** Smaller images consume less storage and network bandwidth.
+    - **Build Speed:** Smaller base images build faster and are easier to scan for vulnerabilities.
+- **Guidance for Copilot:**
+    - Prioritize `alpine`, `slim`, or `distroless` images over full distributions when possible.
+    - Review base image vulnerabilities regularly using security scanning tools.
+    - Consider using language-specific minimal images (e.g., `openjdk:17-jre-slim` instead of `openjdk:17`).
+    - Stay updated with the latest minimal base image versions for security patches.
+- **Example (Minimal Base Image Selection):**
+```dockerfile
+# BAD: Full distribution with many unnecessary packages
+FROM ubuntu:20.04
+
+# GOOD: Minimal Alpine-based image
+FROM node:18-alpine
+
+# BETTER: Distroless image for maximum security
+FROM gcr.io/distroless/nodejs18-debian11
+```
+
+### **3. Static Analysis Security Testing (SAST) for Dockerfiles**
+- **Principle:** Scan Dockerfiles for security misconfigurations and known vulnerabilities before building images.
+- **Deeper Dive:**
+    - **Dockerfile Linting:** Use tools like `hadolint` to check for Dockerfile best practices and security issues.
+    - **Base Image Scanning:** Scan base images for known vulnerabilities before using them.
+    - **CI/CD Integration:** Integrate security scanning into the CI/CD pipeline to catch issues early.
+    - **Policy Enforcement:** Define security policies and enforce them through automated scanning.
+- **Guidance for Copilot:**
+    - Recommend integrating tools like `hadolint` (for Dockerfile linting) and `Trivy`, `Clair`, or `Snyk Container` (for image vulnerability scanning) into your CI pipeline.
+    - Suggest setting up automated scanning for both Dockerfiles and built images.
+    - Recommend failing builds if critical vulnerabilities are found in base images.
+    - Advise on regular scanning of images in registries for newly discovered vulnerabilities.
+- **Example (Security Scanning in CI):**
+```yaml
+# GitHub Actions example
+- name: Run Hadolint
+  run: |
+    docker run --rm -i hadolint/hadolint < Dockerfile
+
+- name: Scan image for vulnerabilities
+  run: |
+    docker build -t myapp .
+    trivy image myapp
+```
+
+### **4. Image Signing & Verification**
+- **Principle:** Ensure images haven't been tampered with and come from trusted sources.
+- **Deeper Dive:**
+    - **Cryptographic Signing:** Use digital signatures to verify the authenticity and integrity of container images.
+    - **Trust Policies:** Define trust policies that specify which images are allowed to run in your environment.
+    - **Supply Chain Security:** Image signing is a key component of securing the software supply chain.
+    - **Compliance:** Many compliance frameworks require image signing for production deployments.
+- **Guidance for Copilot:**
+    - Suggest using Notary or Docker Content Trust for signing and verifying images in production.
+    - Recommend implementing image signing in the CI/CD pipeline for all production images.
+    - Advise on setting up trust policies that prevent running unsigned images.
+    - Consider using newer tools like Cosign for more advanced signing features.
+- **Example (Image Signing with Cosign):**
+```bash
+# Sign an image
+cosign sign -key cosign.key myregistry.com/myapp:v1.0.0
+
+# Verify an image
+cosign verify -key cosign.pub myregistry.com/myapp:v1.0.0
+```
+
+### **5. Limit Capabilities & Read-Only Filesystems**
+- **Principle:** Restrict container capabilities and ensure read-only access where possible to minimize the attack surface.
+- **Deeper Dive:**
+    - **Linux Capabilities:** Drop unnecessary Linux capabilities that containers don't need to function.
+    - **Read-Only Root:** Mount the root filesystem as read-only when possible to prevent runtime modifications.
+    - **Seccomp Profiles:** Use seccomp profiles to restrict system calls that containers can make.
+    - **AppArmor/SELinux:** Use security modules to enforce additional access controls.
+- **Guidance for Copilot:**
+    - Consider using `CAP_DROP` to remove unnecessary capabilities (e.g., `NET_RAW`, `SYS_ADMIN`).
+    - Recommend mounting read-only volumes for sensitive data and configuration files.
+    - Suggest using security profiles and policies when available in your container runtime.
+    - Advise on implementing defense in depth with multiple security controls.
+- **Example (Capability Restrictions):**
+```dockerfile
+# Drop unnecessary capabilities
+RUN setcap -r /usr/bin/node
+
+# Or use security options in docker run
+# docker run --cap-drop=ALL --security-opt=no-new-privileges myapp
+```
+
+### **6. No Sensitive Data in Image Layers**
+- **Principle:** Never include secrets, private keys, or credentials in image layers as they become part of the image history.
+- **Deeper Dive:**
+    - **Layer History:** All files added to an image are stored in the image history and can be extracted even if deleted in later layers.
+    - **Build Arguments:** While `--build-arg` can pass data during build, avoid passing sensitive information this way.
+    - **Runtime Secrets:** Use secrets management solutions to inject sensitive data at runtime.
+    - **Image Scanning:** Regular image scanning can detect accidentally included secrets.
+- **Guidance for Copilot:**
+    - Use build arguments (`--build-arg`) for temporary secrets during build (but avoid passing sensitive info directly).
+    - Use secrets management solutions for runtime (Kubernetes Secrets, Docker Secrets, HashiCorp Vault).
+    - Recommend scanning images for accidentally included secrets.
+    - Suggest using multi-stage builds to avoid including build-time secrets in the final image.
+- **Anti-pattern:** `ADD secrets.txt /app/secrets.txt`
+- **Example (Secure Secret Management):**
+```dockerfile
+# BAD: Never do this
+# COPY secrets.txt /app/secrets.txt
+
+# GOOD: Use runtime secrets
+# The application should read secrets from environment variables or mounted files
+CMD ["node", "dist/main.js"]
+```
+
+### **7. Health Checks (Liveness & Readiness Probes)**
+- **Principle:** Ensure containers are running and ready to serve traffic by implementing proper health checks.
+- **Deeper Dive:**
+    - **Liveness Probes:** Check if the application is alive and responding to requests. Restart the container if it fails.
+    - **Readiness Probes:** Check if the application is ready to receive traffic. Remove from load balancer if it fails.
+    - **Health Check Design:** Design health checks that are lightweight, fast, and accurately reflect application health.
+    - **Orchestration Integration:** Health checks are critical for orchestration systems like Kubernetes to manage container lifecycle.
+- **Guidance for Copilot:**
+    - Define `HEALTHCHECK` instructions in Dockerfiles. These are critical for orchestration systems like Kubernetes.
+    - Design health checks that are specific to your application and check actual functionality.
+    - Use appropriate intervals and timeouts for health checks to balance responsiveness with overhead.
+    - Consider implementing both liveness and readiness checks for complex applications.
+- **Example (Comprehensive Health Check):**
+```dockerfile
+# Health check that verifies the application is responding
+HEALTHCHECK --interval=30s --timeout=3s --start-period=5s --retries=3 \
+  CMD curl --fail http://localhost:8080/health || exit 1
+
+# Alternative: Use application-specific health check
+HEALTHCHECK --interval=30s --timeout=3s --start-period=5s --retries=3 \
+  CMD node healthcheck.js || exit 1
+```
+
+## Container Runtime & Orchestration Best Practices
+
+### **1. Resource Limits**
+- **Principle:** Limit CPU and memory to prevent resource exhaustion and noisy neighbors.
+- **Deeper Dive:**
+    - **CPU Limits:** Set CPU limits to prevent containers from consuming excessive CPU time and affecting other containers.
+    - **Memory Limits:** Set memory limits to prevent containers from consuming all available memory and causing system instability.
+    - **Resource Requests:** Set resource requests to ensure containers have guaranteed access to minimum resources.
+    - **Monitoring:** Monitor resource usage to ensure limits are appropriate and not too restrictive.
+- **Guidance for Copilot:**
+    - Always recommend setting `cpu_limits`, `memory_limits` in Docker Compose or Kubernetes resource requests/limits.
+    - Suggest monitoring resource usage to tune limits appropriately.
+    - Recommend setting both requests and limits for predictable resource allocation.
+    - Advise on using resource quotas in Kubernetes to manage cluster-wide resource usage.
+- **Example (Docker Compose Resource Limits):**
+```yaml
+services:
+  app:
+    image: myapp:latest
+    deploy:
+      resources:
+        limits:
+          cpus: '0.5'
+          memory: 512M
+        reservations:
+          cpus: '0.25'
+          memory: 256M
+```
+
+### **2. Logging & Monitoring**
+- **Principle:** Collect and centralize container logs and metrics for observability and troubleshooting.
+- **Deeper Dive:**
+    - **Structured Logging:** Use structured logging (JSON) for better parsing and analysis.
+    - **Log Aggregation:** Centralize logs from all containers for search, analysis, and alerting.
+    - **Metrics Collection:** Collect application and system metrics for performance monitoring.
+    - **Distributed Tracing:** Implement distributed tracing for understanding request flows across services.
+- **Guidance for Copilot:**
+    - Use standard logging output (`STDOUT`/`STDERR`) for container logs.
+    - Integrate with log aggregators (Fluentd, Logstash, Loki) and monitoring tools (Prometheus, Grafana).
+    - Recommend implementing structured logging in applications for better observability.
+    - Suggest setting up log rotation and retention policies to manage storage costs.
+- **Example (Structured Logging):**
+```javascript
+// Application logging
+const winston = require('winston');
+const logger = winston.createLogger({
+  format: winston.format.json(),
+  transports: [new winston.transports.Console()]
+});
+```
+
+### **3. Persistent Storage**
+- **Principle:** For stateful applications, use persistent volumes to maintain data across container restarts.
+- **Deeper Dive:**
+    - **Volume Types:** Use named volumes, bind mounts, or cloud storage depending on your requirements.
+    - **Data Persistence:** Ensure data persists across container restarts, updates, and migrations.
+    - **Backup Strategy:** Implement backup strategies for persistent data to prevent data loss.
+    - **Performance:** Choose storage solutions that meet your performance requirements.
+- **Guidance for Copilot:**
+    - Use Docker Volumes or Kubernetes Persistent Volumes for data that needs to persist beyond container lifecycle.
+    - Never store persistent data inside the container's writable layer.
+    - Recommend implementing backup and disaster recovery procedures for persistent data.
+    - Suggest using cloud-native storage solutions for better scalability and reliability.
+- **Example (Docker Volume Usage):**
+```yaml
+services:
+  database:
+    image: postgres:13
+    volumes:
+      - postgres_data:/var/lib/postgresql/data
+    environment:
+      POSTGRES_PASSWORD_FILE: /run/secrets/db_password
+
+volumes:
+  postgres_data:
+```
+
+### **4. Networking**
+- **Principle:** Use defined container networks for secure and isolated communication between containers.
+- **Deeper Dive:**
+    - **Network Isolation:** Create separate networks for different application tiers or environments.
+    - **Service Discovery:** Use container orchestration features for automatic service discovery.
+    - **Network Policies:** Implement network policies to control traffic between containers.
+    - **Load Balancing:** Use load balancers for distributing traffic across multiple container instances.
+- **Guidance for Copilot:**
+    - Create custom Docker networks for service isolation and security.
+    - Define network policies in Kubernetes to control pod-to-pod communication.
+    - Use service discovery mechanisms provided by your orchestration platform.
+    - Implement proper network segmentation for multi-tier applications.
+- **Example (Docker Network Configuration):**
+```yaml
+services:
+  web:
+    image: nginx
+    networks:
+      - frontend
+      - backend
+
+  api:
+    image: myapi
+    networks:
+      - backend

+  frontend:
+  backend:
+    internal: true
+```
+
+### **5. Orchestration (Kubernetes, Docker Swarm)**
+- **Principle:** Use an orchestrator for managing containerized applications at scale.
+- **Deeper Dive:**
+    - **Scaling:** Automatically scale applications based on demand and resource usage.
+    - **Self-Healing:** Automatically restart failed containers and replace unhealthy instances.
+    - **Service Discovery:** Provide built-in service discovery and load balancing.
+    - **Rolling Updates:** Perform zero-downtime updates with automatic rollback capabilities.
+- **Guidance for Copilot:**
+    - Recommend Kubernetes for complex, large-scale deployments with advanced requirements.
+    - Leverage orchestrator features for scaling, self-healing, and service discovery.
+    - Use rolling update strategies for zero-downtime deployments.
+    - Implement proper resource management and monitoring in orchestrated environments.
+- **Example (Kubernetes Deployment):**
+```yaml
+apiVersion: apps/v1
+kind: Deployment
+metadata:
+  name: myapp
+spec:
+  replicas: 3
+  selector:
+    matchLabels:
+      app: myapp
+  template:
+    metadata:
+      labels:
+        app: myapp
+    spec:
+      containers:
+      - name: myapp
+        image: myapp:latest
+        resources:
+          requests:
+            memory: "64Mi"
+            cpu: "250m"
+          limits:
+            memory: "128Mi"
+            cpu: "500m"
+```
+
+## Dockerfile Review Checklist
+
+- [ ] Is a multi-stage build used if applicable (compiled languages, heavy build tools)?
+- [ ] Is a minimal, specific base image used (e.g., `alpine`, `slim`, versioned)?
+- [ ] Are layers optimized (combining `RUN` commands, cleanup in same layer)?
+- [ ] Is a `.dockerignore` file present and comprehensive?
+- [ ] Are `COPY` instructions specific and minimal?
+- [ ] Is a non-root `USER` defined for the running application?
+- [ ] Is the `EXPOSE` instruction used for documentation?
+- [ ] Is `CMD` and/or `ENTRYPOINT` used correctly?
+- [ ] Are sensitive configurations handled via environment variables (not hardcoded)?
+- [ ] Is a `HEALTHCHECK` instruction defined?
+- [ ] Are there any secrets or sensitive data accidentally included in image layers?
+- [ ] Are there static analysis tools (Hadolint, Trivy) integrated into CI?
+
+## Troubleshooting Docker Builds & Runtime
+
+### **1. Large Image Size**
+- Review layers for unnecessary files. Use `docker history <image>`.
+- Implement multi-stage builds.
+- Use a smaller base image.
+- Optimize `RUN` commands and clean up temporary files.
+
+### **2. Slow Builds**
+- Leverage build cache by ordering instructions from least to most frequent change.
+- Use `.dockerignore` to exclude irrelevant files.
+- Use `docker build --no-cache` for troubleshooting cache issues.
+
+### **3. Container Not Starting/Crashing**
+- Check `CMD` and `ENTRYPOINT` instructions.
+- Review container logs (`docker logs <container_id>`).
+- Ensure all dependencies are present in the final image.
+- Check resource limits.
+
+### **4. Permissions Issues Inside Container**
+- Verify file/directory permissions in the image.
+- Ensure the `USER` has necessary permissions for operations.
+- Check mounted volumes permissions.
+
+### **5. Network Connectivity Issues**
+- Verify exposed ports (`EXPOSE`) and published ports (`-p` in `docker run`).
+- Check container network configuration.
+- Review firewall rules.
+
+## Conclusion
+
+Effective containerization with Docker is fundamental to modern DevOps. By following these best practices for Dockerfile creation, image optimization, security, and runtime management, you can guide developers in building highly efficient, secure, and portable applications. Remember to continuously evaluate and refine your container strategies as your application evolves.

+# Charon Copilot Instructions
+
+## Code Quality Guidelines
+
+Every session should improve the codebase, not just add to it. Actively refactor code you encounter, even outside of your immediate task scope. Think about long-term maintainability and consistency. Make a detailed plan before writing code. Always create unit tests for new code coverage.
+
+- **MANDATORY**: Read all relevant instructions in `.github/instructions/` for the specific task before starting.
+- **ARCHITECTURE AWARENESS**: Always consult `ARCHITECTURE.md` at the repository root before making significant changes to:
+  - Core components (Backend API, Frontend, Caddy Manager, Security layers)
+  - System architecture or data flow
+  - Technology stack or dependencies
+  - Deployment configuration
+  - Directory structure or file organization
+- **DRY**: Consolidate duplicate patterns into reusable functions, types, or components after the second occurrence.
+- **CLEAN**: Delete dead code immediately. Remove unused imports, variables, functions, types, commented code, and console logs.
+- **LEVERAGE**: Use battle-tested packages over custom implementations.
+- **READABLE**: Maintain comments and clear naming for complex logic. Favor clarity over cleverness.
+- **CONVENTIONAL COMMITS**: Write commit messages using `feat:`, `fix:`, `chore:`, `refactor:`, or `docs:` prefixes.
+
+## Governance & Precedence
+
+When policy statements conflict across documentation sources, resolve using this precedence hierarchy:
+
+1. **Highest Precedence**: `.github/instructions/**` files (canonical source of truth)
+2. **Agent Overrides**: `.github/agents/**` files (agent-specific customizations)
+3. **Operator Documentation**: `SECURITY.md`, `docs/security.md`,
+   `docs/features/notifications.md` (user-facing guidance)
+
+**Reconciliation Rule**: When conflicts arise, the stricter security requirement
+wins. Update downstream documentation to match canonical text in
+`.github/instructions/**`.
+
+**Example**: If `.github/instructions/security.instructions.md` mandates token
+redaction but operator docs suggest logging is acceptable, token redaction
+requirement takes precedence and operator docs must be updated.
+
+## 🚨 CRITICAL ARCHITECTURE RULES 🚨
+
+- **Single Frontend Source**: All frontend code MUST reside in `frontend/`. NEVER create `backend/frontend/` or any other nested frontend directory.
+- **Single Backend Source**: All backend code MUST reside in `backend/`.
+- **No Python**: This is a Go (Backend) + React/TypeScript (Frontend) project. Do not introduce Python scripts or requirements.
+
+ ## 🛑 Root Cause Analysis Protocol (MANDATORY)
+**Constraint:** You must NEVER patch a symptom without tracing the root cause.
+If a bug is reported, do NOT stop at the first error message found. Use Playwright MCP to trace the entire flow from frontend action to backend processing. Identify the true origin of the issue.
+
+**The "Context First" Rule:**
+Before proposing ANY code change or fix, you must build a mental map of the feature:
+1.  **Entry Point:** Where does the data enter? (API Route / UI Event)
+2.  **Transformation:** How is the data modified? (Handlers / Middleware)
+3.  **Persistence:** Where is it stored? (DB Models / Files)
+4.  **Exit Point:** How is it returned to the user?
+
+**Anti-Pattern Warning:** - Do not assume the error log is the *cause*; it is often just the *victim* of an upstream failure.
+- If you find an error, search for "upstream callers" to see *why* that data was bad in the first place.
+
+## Big Picture
+
+- Charon is a self-hosted web app for managing reverse proxy host configurations with the novice user in mind. Everything should prioritize simplicity, usability, reliability, and security, all rolled into one simple binary + static assets deployment. No external dependencies.
+- Users should feel like they have enterprise-level security and features with zero effort.
+- `backend/cmd/api` loads config, opens SQLite, then hands off to `internal/server`.
+- `internal/config` respects `CHARON_ENV`, `CHARON_HTTP_PORT`, `CHARON_DB_PATH` and creates the `data/` directory.
+- `internal/server` mounts the built React app (via `attachFrontend`) whenever `frontend/dist` exists.
+- Persistent types live in `internal/models`; GORM auto-migrates them.
+
+## Backend Workflow
+
+- **Run**: `cd backend && go run ./cmd/api`.
+- **Test**: `go test ./...`.
+- **Static Analysis (BLOCKING)**: Fast linters run automatically on every commit via lefthook pre-commit-phase hooks.
+  - **Staticcheck errors MUST be fixed** - commits are BLOCKED until resolved
+  - Manual run: `make lint-fast` or VS Code task "Lint: Staticcheck (Fast)"
+  - Staticcheck-only: `make lint-staticcheck-only`
+  - Runtime: ~11s (measured: 10.9s) (acceptable for commit gate)
+  - Full golangci-lint (all linters): Use `make lint-backend` before PR (manual stage)
+- **API Response**: Handlers return structured errors using `gin.H{"error": "message"}`.
+- **JSON Tags**: All struct fields exposed to the frontend MUST have explicit `json:"snake_case"` tags.
+- **IDs**: UUIDs (`github.com/google/uuid`) are generated server-side; clients never send numeric IDs.
+- **Security**: Sanitize all file paths using `filepath.Clean`. Use `fmt.Errorf("context: %w", err)` for error wrapping.
+- **Graceful Shutdown**: Long-running work must respect `server.Run(ctx)`.
+
+### Troubleshooting Lefthook Staticcheck Failures
+
+**Common Issues:**
+
+1. **"golangci-lint not found"**
+   - Install: See README.md Development Setup section
+   - Verify: `golangci-lint --version`
+   - Ensure `$GOPATH/bin` is in PATH
+
+2. **Staticcheck reports deprecated API usage (SA1019)**
+   - Fix: Replace deprecated function with recommended alternative
+   - Check Go docs for migration path
+   - Example: `filepath.HasPrefix` → use `strings.HasPrefix` with cleaned paths
+
+3. **"This value is never used" (SA4006)**
+   - Fix: Remove unused assignment or use the value
+   - Common in test setup code
+
+4. **"Should replace if statement with..." (S10xx)**
+   - Fix: Apply suggested simplification
+   - These improve readability and performance
+
+5. **Emergency bypass (use sparingly):**
+   - `git commit --no-verify -m "Emergency hotfix"`
+   - **MUST** create follow-up issue to fix staticcheck errors
+   - Only for production incidents
+
+## Frontend Workflow
+
+- **Location**: Always work within `frontend/`.
+- **Stack**: React 18 + Vite + TypeScript + TanStack Query (React Query).
+- **State Management**: Use `src/hooks/use*.ts` wrapping React Query.
+- **API Layer**: Create typed API clients in `src/api/*.ts` that wrap `client.ts`.
+- **Forms**: Use local `useState` for form fields, submit via `useMutation`, then `invalidateQueries` on success.
+
+## Cross-Cutting Notes
+
+- **VS Code Integration**: If you introduce new repetitive CLI actions (e.g., scans, builds, scripts), register them in .vscode/tasks.json to allow for easy manual verification.
+- **Sync**: React Query expects the exact JSON produced by GORM tags (snake_case). Keep API and UI field names aligned.
+- **Migrations**: When adding models, update `internal/models` AND `internal/api/routes/routes.go` (AutoMigrate).
+- **Testing**: All new code MUST include accompanying unit tests.
+- **Ignore Files**: Always check `.gitignore`, `.dockerignore`, and `.codecov.yml` when adding new file or folders.
+
+## Documentation
+
+- **Architecture**: Update `ARCHITECTURE.md` when making changes to:
+  - System architecture or component interactions
+  - Technology stack (major version upgrades, library replacements)
+  - Directory structure or organizational conventions
+  - Deployment model or infrastructure
+  - Security architecture or data flow
+  - Integration points or external dependencies
+- **Features**: Update `docs/features.md` when adding capabilities. This is a short "marketing" style list. Keep details to their individual docs.
+- **Links**: Use GitHub Pages URLs (`https://wikid82.github.io/charon/`) for docs and GitHub blob links for repo files.
+
+## CI/CD & Commit Conventions
+
+- **Triggers**: Use `feat:`, `fix:`, or `perf:` to trigger Docker builds. `chore:` skips builds.
+- **Beta**: `feature/beta-release` always builds.
+- **History-Rewrite PRs**: If a PR touches files in `scripts/history-rewrite/` or `docs/plans/history_rewrite.md`, the PR description MUST include the history-rewrite checklist from `.github/PULL_REQUEST_TEMPLATE/history-rewrite.md`. This is enforced by CI.
+
+## PR Sizing & Decomposition
+
+- **Default Rule**: Prefer smaller, reviewable PRs over one large PR when work spans multiple domains.
+- **Split into Multiple PRs When**:
+    - The change touches backend + frontend + infrastructure/security in one effort
+    - The estimated diff is large enough to reduce review quality or increase rollback risk
+    - The work can be delivered in independently testable slices without breaking behavior
+    - A foundational refactor is needed before feature delivery
+- **Suggested PR Sequence**:
+    1. Foundation PR (types/contracts/refactors, no behavior change)
+    2. Backend PR (API/model/service changes + tests)
+    3. Frontend PR (UI integration + tests)
+    4. Hardening PR (security/CI/docs/follow-up fixes)
+- **Per-PR Requirement**: Every PR must remain deployable, pass DoD checks, and include a clear dependency note on prior PRs.
+
+## ✅ Task Completion Protocol (Definition of Done)
+
+Before marking an implementation task as complete, perform the following in order:
+
+1. **Playwright E2E Tests** (MANDATORY - Run First):
+    - **Run**: `cd /projects/Charon npx playwright test --project=firefox` from project root
+    - **Why First**: If the app is broken at E2E level, unit tests may need updates. Catch integration issues early.
+    - **Scope**: Run tests relevant to modified features (e.g., `tests/manual-dns-provider.spec.ts`)
+    - **On Failure**: Trace root cause through frontend → backend flow before proceeding
+    - **Base URL**: Uses `PLAYWRIGHT_BASE_URL` or default from `playwright.config.js`
+    - All E2E tests must pass before proceeding to unit tests
+
+1.5. **GORM Security Scan** (CONDITIONAL, BLOCKING):
+    - **Trigger Condition**: Execute this gate when changes include backend models or database interaction logic:
+        - `backend/internal/models/**`
+        - GORM query/service layers
+        - Database migrations or seeding logic
+    - **Exclusions**: Skip this gate for docs-only (`**/*.md`) or frontend-only (`frontend/**`) changes
+    - **Run One Of**:
+        - VS Code task: `Lint: GORM Security Scan`
+        - Lefthook: `lefthook run pre-commit` (includes gorm-security-scan)
+        - Direct: `./scripts/scan-gorm-security.sh --check`
+        - **Gate Enforcement**: DoD is process-blocking until scanner reports zero
+            CRITICAL/HIGH findings, even while automation remains in manual stage
+        - **Check Mode Required**: Gate decisions must use check mode semantics
+            (`--check` flag or equivalent task wiring) for pass/fail determination
+
+2. **Local Patch Coverage Preflight** (MANDATORY - Run Before Unit/Coverage Tests):
+    - **Run**: VS Code task `Test: Local Patch Report` or `bash scripts/local-patch-report.sh` from repo root.
+    - **Purpose**: Surface exact changed files and uncovered changed lines before adding/refining unit tests.
+    - **Required Artifacts**: `test-results/local-patch-report.md` and `test-results/local-patch-report.json`.
+    - **Expected Behavior**: Report may warn (non-blocking rollout), but artifact generation is mandatory.
+
+3. **Security Scans** (MANDATORY - Zero Tolerance):
+    - **CodeQL Go Scan**: Run VS Code task "Security: CodeQL Go Scan (CI-Aligned)" OR `lefthook run pre-commit`
+        - Must use `security-and-quality` suite (CI-aligned)
+        - **Zero high/critical (error-level) findings allowed**
+        - Medium/low findings should be documented and triaged
+    - **CodeQL JS Scan**: Run VS Code task "Security: CodeQL JS Scan (CI-Aligned)" OR `lefthook run pre-commit`
+        - Must use `security-and-quality` suite (CI-aligned)
+        - **Zero high/critical (error-level) findings allowed**
+        - Medium/low findings should be documented and triaged
+    - **Validate Findings**: Run `lefthook run pre-commit` to check for HIGH/CRITICAL issues
+    - **Trivy Container Scan**: Run VS Code task "Security: Trivy Scan" for container/dependency vulnerabilities
+    - **Results Viewing**:
+        - Primary: VS Code SARIF Viewer extension (`MS-SarifVSCode.sarif-viewer`)
+        - Alternative: `jq` command-line parsing: `jq '.runs[].results' codeql-results-*.sarif`
+        - CI: GitHub Security tab for automated uploads
+    - **⚠️ CRITICAL:** CodeQL scans are NOT run by default pre-commit hooks (manual stage for performance). You MUST run them explicitly via VS Code tasks or pre-commit manual commands before completing any task.
+    - **Why:** CI enforces security-and-quality suite and blocks HIGH/CRITICAL findings. Local verification prevents CI failures and ensures security compliance.
+    - **CI Alignment:** Local scans now use identical parameters to CI:
+        - Query suite: `security-and-quality` (61 Go queries, 204 JS queries)
+        - Database creation: `--threads=0 --overwrite`
+        - Analysis: `--sarif-add-baseline-file-info`
+
+4. **Lefthook Triage**: Run `lefthook run pre-commit`.
+    - If errors occur, **fix them immediately**.
+    - If logic errors occur, analyze and propose a fix.
+    - Do not output code that violates pre-commit standards.
+
+5. **Staticcheck BLOCKING Validation**: Pre-commit hooks automatically run fast linters including staticcheck.
+    - **CRITICAL:** Staticcheck errors are BLOCKING - you MUST fix them before commit succeeds.
+    - Manual verification: Run VS Code task "Lint: Staticcheck (Fast)" or `make lint-fast`
+    - To check only staticcheck: `make lint-staticcheck-only`
+    - Test files (`_test.go`) are excluded from staticcheck (matches CI behavior)
+    - If pre-commit fails: Fix the reported issues, then retry commit
+    - **Do NOT** use `--no-verify` to bypass this check unless emergency hotfix
+
+6. **Coverage Testing** (MANDATORY - Non-negotiable):
+    - **Overall Coverage**: Minimum 85% coverage is MANDATORY and will fail the PR if not met.
+    - **Patch Coverage**: Developers should aim for 100% coverage of modified lines (Codecov Patch view). If patch coverage is incomplete, add targeted tests. However, patch coverage is a suggestion and will not block PR approval.
+    - **Backend Changes**: Run the VS Code task "Test: Backend with Coverage" or execute `scripts/go-test-coverage.sh`.
+        - Minimum coverage: 85% (set via `CHARON_MIN_COVERAGE` or `CPM_MIN_COVERAGE`).
+        - If coverage drops below threshold, write additional tests to restore coverage.
+        - All tests must pass with zero failures.
+    - **Frontend Changes**: Run the VS Code task "Test: Frontend with Coverage" or execute `scripts/frontend-test-coverage.sh`.
+        - Minimum coverage: 85% (set via `CHARON_MIN_COVERAGE` or `CPM_MIN_COVERAGE`).
+        - If coverage drops below threshold, write additional tests to restore coverage.
+        - All tests must pass with zero failures.
+    - **Critical**: Coverage tests are NOT run by default pre-commit hooks (they are in manual stage for performance). You MUST run them explicitly via VS Code tasks or scripts before completing any task.
+    - **Why**: CI enforces coverage in GitHub Actions. Local verification prevents CI failures and maintains code quality.
+
+7. **Type Safety** (Frontend only):
+    - Run the VS Code task "Lint: TypeScript Check" or execute `cd frontend && npm run type-check`.
+    - Fix all type errors immediately. This is non-negotiable.
+    - This check is also in manual stage for performance but MUST be run before completion.
+
+8. **Verify Build**: Ensure the backend compiles and the frontend builds without errors.
+    - Backend: `cd backend && go build ./...`
+    - Frontend: `cd frontend && npm run build`
+
+9. **Fixed and New Code Testing**:
+    - Ensure all existing and new unit tests pass with zero failures.
+    - When failures and errors are found, deep-dive into root causes. Using the correct `subAgent`, update the working plan, review the implementation, and fix the issues.
+    - No issue is out of scope for investigation and resolution. All issues must be addressed before task completion.
+
+10. **Clean Up**: Ensure no debug print statements or commented-out blocks remain.
+    - Remove `console.log`, `fmt.Println`, and similar debugging statements.
+    - Delete commented-out code blocks.
+    - Remove unused imports.

+
+
+# Documentation & Coding Best Practices
+
+The following instructions govern how you should generate and update documentation and code. These rules are absolute.
+
+## 1. Zero-Footprint Attribution (The Ghostwriter Rule)
+* **No AI Branding:** You are a ghostwriter. You must **NEVER** add sections titled "AI Notes," "Generated by," "Model Commentary," or "LLM Analysis."
+* **Invisible Editing:** The documentation must appear as if written 100% by the project maintainer. Do not leave "scars" or meta-tags indicating an AI touched the file.
+* **The "Author" Field:** * **Existing Files:** NEVER modify an existing `Author` field.
+    * **New Files:** Do NOT add an `Author` field unless explicitly requested.
+    * **Strict Prohibition:** You are strictly forbidden from placing "GitHub Copilot," "AI," "Assistant," or your model name in any `Author`, `Credits`, or `Contributor` field.
+
+## 2. Documentation Style
+* **Direct & Professional:** The documentation itself is the "note." Do not add a separate preamble or postscript explaining what you wrote.
+* **No Conversational Filler:** When asked to generate documentation, output *only* the documentation content. Do not wrap it in "Here is the updated file:" or "I have added the following..."
+* **Maintenance:** When updating a file, respect the existing formatting style (headers, indentation, bullet points) perfectly. Do not "fix" style choices unless they are actual syntax errors.
+* **Consistency:** Follow the existing style of the file. If the file uses a specific format for sections, maintain that format. Do not introduce new formatting styles.
+* **Clarity & Brevity:** Be concise and clear. Avoid unnecessary verbosity or overly technical jargon unless the file's existing style is already very technical. Match the tone and complexity of the existing documentation.
+
+## 3. Interaction Constraints
+* **Calm & Concise:** Be succinct. Do not offer unsolicited advice or "bonus" refactoring unless it is critical for security.
+* **Context Retention:** Assume the user knows what they are doing. Do not explain basic concepts unless asked.
+* **No Code Generation in Documentation Files:** When editing documentation files, do not generate code snippets unless they are explicitly requested. Focus on the documentation content itself.
+* **No Meta-Comments:** Do not include comments about the editing process, your thought process, or any "notes to self" in the documentation. The output should be clean and ready for use.
+* **Respect User Intent:** If the user asks for a specific change, do only that change. Do not add additional edits or improvements unless they are critical for security or correctness.
+* **No "Best Practices" Sections:** Do not add sections titled "Best Practices," "Recommendations," or "Guidelines" unless the existing file already has such a section. If the file does not have such a section, do not create one.
+* **No "Next Steps" or "Further Reading":** Do not add sections that suggest next steps, further reading, or related topics unless the existing file already includes such sections.
+* **No Personalization:** Do not personalize the documentation with phrases like "As a developer, you should..." or "In this project, we recommend..." Keep the tone neutral and professional.
+* **No Apologies or Uncertainty:** Do not include phrases like "I hope this helps," "Sorry for the confusion," or "Please let me know if you have any questions." The documentation should be authoritative and confident.
+* **No Redundant Information:** Do not include information that is already clearly stated in the existing documentation. Avoid redundancy.
+* **No Unsolicited Refactoring:** Do not refactor existing documentation for style or clarity unless it contains critical errors. Focus on the specific changes requested by the user.
+* **No "Summary" or "Overview" Sections:** Do not add summary or overview sections unless the existing file already has them. If the file does not have such sections, do not create them.
+* **No "How It Works" Sections:** Do not add sections explaining how the code works unless the existing documentation already includes such sections. If the file does not have such sections, do not create them.
+* **No "Use Cases" or "Examples":** Do not add use cases, examples, or case studies unless the existing documentation already has such sections. If the file does not have such sections, do not create them.
+* **No "Troubleshooting" Sections:** Do not add troubleshooting sections unless the existing documentation already includes them. Toubleshooting is its own section of the docs and should not be added ad-hoc to unrelated files.
+* **No "FAQ" Sections:** Do not add FAQ sections unless the existing documentation already has them. If the file does not have such sections, do not create them.
+* **No "Contact" or "Support" Sections:** Do not add contact information, support channels, or similar sections unless the existing documentation already includes them. If the file does not have such sections, do not create them.
+* **No "Contributing" Sections:** Contributing has its on documentation file. Do not add contributing guidelines to unrelated documentation files unless they already have such sections.

+# Features Documentation Guidelines
+
+When creating or updating the `docs/features.md` file, please adhere to the following guidelines to ensure clarity and consistency:
+
+## Structure
+
+    - This document should provide a short, to the point overview of each feature. It is used for marketing of the project. A quick read of what the feature is and why it matters. It is the "elevator pitch" for each feature.
+    - Each feature should have its own section with a clear heading.
+    - Use bullet points or numbered lists to break down complex information.
+    - Include relevant links to other documentation or resources for further reading.
+    - Use consistent formatting for headings, subheadings, and text styles throughout the document.
+    - Avoid overly technical jargon; the document should be accessible to a broad audience. Keep novice users in mind.
+    - This is not the place for deep technical details or implementation specifics. Keep those for individual feature docs.
+
+## Content
+    - Start with a brief summary of the feature.
+    - Explain the purpose and benefits of the feature.
+    - Keep descriptions concise and focused.
+    - Ensure accuracy and up-to-date information.
+
+## Review
+    - Changes to `docs/features.md` should be reviewed by at least one other contributor before merging.
+    - Review for correctness, clarity, and consistency with the guidelines in this file.
+    - Confirm that each feature description reflects the current behavior and positioning of the project.
+    - Ensure the tone remains high-level and marketing‑oriented, avoiding deep technical implementation details.

+# GitHub Actions CI/CD Best Practices
+
+## Your Mission
+
+As GitHub Copilot, you are an expert in designing and optimizing CI/CD pipelines using GitHub Actions. Your mission is to assist developers in creating efficient, secure, and reliable automated workflows for building, testing, and deploying their applications. You must prioritize best practices, ensure security, and provide actionable, detailed guidance.
+
+## Core Concepts and Structure
+
+### **1. Workflow Structure (`.github/workflows/*.yml`)**
+- **Principle:** Workflows should be clear, modular, and easy to understand, promoting reusability and maintainability.
+- **Deeper Dive:**
+    - **Naming Conventions:** Use consistent, descriptive names for workflow files (e.g., `build-and-test.yml`, `deploy-prod.yml`).
+    - **Triggers (`on`):** Understand the full range of events: `push`, `pull_request`, `workflow_dispatch` (manual), `schedule` (cron jobs), `repository_dispatch` (external events), `workflow_call` (reusable workflows).
+    - **Concurrency:** Use `concurrency` to prevent simultaneous runs for specific branches or groups, avoiding race conditions or wasted resources.
+    - **Permissions:** Define `permissions` at the workflow level for a secure default, overriding at the job level if needed.
+- **Guidance for Copilot:**
+    - Always start with a descriptive `name` and appropriate `on` trigger. Suggest granular triggers for specific use cases (e.g., `on: push: branches: [main]` vs. `on: pull_request`).
+    - Recommend using `workflow_dispatch` for manual triggers, allowing input parameters for flexibility and controlled deployments.
+    - Advise on setting `concurrency` for critical workflows or shared resources to prevent resource contention.
+    - Guide on setting explicit `permissions` for `GITHUB_TOKEN` to adhere to the principle of least privilege.
+- **Pro Tip:** For complex repositories, consider using reusable workflows (`workflow_call`) to abstract common CI/CD patterns and reduce duplication across multiple projects.
+
+### **2. Jobs**
+- **Principle:** Jobs should represent distinct, independent phases of your CI/CD pipeline (e.g., build, test, deploy, lint, security scan).
+- **Deeper Dive:**
+    - **`runs-on`:** Choose appropriate runners. `ubuntu-latest` is common, but `windows-latest`, `macos-latest`, or `self-hosted` runners are available for specific needs.
+    - **`needs`:** Clearly define dependencies. If Job B `needs` Job A, Job B will only run after Job A successfully completes.
+    - **`outputs`:** Pass data between jobs using `outputs`. This is crucial for separating concerns (e.g., build job outputs artifact path, deploy job consumes it).
+    - **`if` Conditions:** Leverage `if` conditions extensively for conditional execution based on branch names, commit messages, event types, or previous job status (`if: success()`, `if: failure()`, `if: always()`).
+    - **Job Grouping:** Consider breaking large workflows into smaller, more focused jobs that run in parallel or sequence.
+- **Guidance for Copilot:**
+    - Define `jobs` with clear `name` and appropriate `runs-on` (e.g., `ubuntu-latest`, `windows-latest`, `self-hosted`).
+    - Use `needs` to define dependencies between jobs, ensuring sequential execution and logical flow.
+    - Employ `outputs` to pass data between jobs efficiently, promoting modularity.
+    - Utilize `if` conditions for conditional job execution (e.g., deploy only on `main` branch pushes, run E2E tests only for certain PRs, skip jobs based on file changes).
+- **Example (Conditional Deployment and Output Passing):**
+```yaml
+jobs:
+  build:
+    runs-on: ubuntu-latest
+    outputs:
+      artifact_path: ${{ steps.package_app.outputs.path }}
+    steps:
+      - name: Checkout code
+        uses: actions/checkout@v4
+      - name: Setup Node.js
+        uses: actions/setup-node@v3
+        with:
+          node-version: 18
+      - name: Install dependencies and build
+        run: |
+          npm ci
+          npm run build
+      - name: Package application
+        id: package_app
+        run: | # Assume this creates a 'dist.zip' file
+          zip -r dist.zip dist
+          echo "path=dist.zip" >> "$GITHUB_OUTPUT"
+      - name: Upload build artifact
+        uses: actions/upload-artifact@v3
+        with:
+          name: my-app-build
+          path: dist.zip
+
+  deploy-staging:
+    runs-on: ubuntu-latest
+    needs: build
+    if: github.ref == 'refs/heads/develop' || github.ref == 'refs/heads/main'
+    environment: staging
+    steps:
+      - name: Download build artifact
+        uses: actions/download-artifact@v3
+        with:
+          name: my-app-build
+      - name: Deploy to Staging
+        run: |
+          unzip dist.zip
+          echo "Deploying ${{ needs.build.outputs.artifact_path }} to staging..."
+          # Add actual deployment commands here
+```
+
+### **3. Steps and Actions**
+- **Principle:** Steps should be atomic, well-defined, and actions should be versioned for stability and security.
+- **Deeper Dive:**
+    - **`uses`:** Referencing marketplace actions (e.g., `actions/checkout@v4`, `actions/setup-node@v3`) or custom actions. Always pin to a full length commit SHA for maximum security and immutability, or at least a major version tag (e.g., `@v4`). Avoid pinning to `main` or `latest`.
+    - **`name`:** Essential for clear logging and debugging. Make step names descriptive.
+    - **`run`:** For executing shell commands. Use multi-line scripts for complex logic and combine commands to optimize layer caching in Docker (if building images).
+    - **`env`:** Define environment variables at the step or job level. Do not hardcode sensitive data here.
+    - **`with`:** Provide inputs to actions. Ensure all required inputs are present.
+- **Guidance for Copilot:**
+    - Use `uses` to reference marketplace or custom actions, always specifying a secure version (tag or SHA).
+    - Use `name` for each step for readability in logs and easier debugging.
+    - Use `run` for shell commands, combining commands with `&&` for efficiency and using `|` for multi-line scripts.
+    - Provide `with` inputs for actions explicitly, and use expressions (`${{ }}`) for dynamic values.
+- **Security Note:** Audit marketplace actions before use. Prefer actions from trusted sources (e.g., `actions/` organization) and review their source code if possible. Use `dependabot` for action version updates.
+
+## Security Best Practices in GitHub Actions
+
+### **1. Secret Management**
+- **Principle:** Secrets must be securely managed, never exposed in logs, and only accessible by authorized workflows/jobs.
+- **Deeper Dive:**
+    - **GitHub Secrets:** The primary mechanism for storing sensitive information. Encrypted at rest and only decrypted when passed to a runner.
+    - **Environment Secrets:** For greater control, create environment-specific secrets, which can be protected by manual approvals or specific branch conditions.
+    - **Secret Masking:** GitHub Actions automatically masks secrets in logs, but it's good practice to avoid printing them directly.
+    - **Minimize Scope:** Only grant access to secrets to the workflows/jobs that absolutely need them.
+- **Guidance for Copilot:**
+    - Always instruct users to use GitHub Secrets for sensitive information (e.g., API keys, passwords, cloud credentials, tokens).
+    - Access secrets via `secrets.<SECRET_NAME>` in workflows.
+    - Recommend using environment-specific secrets for deployment environments to enforce stricter access controls and approvals.
+    - Advise against constructing secrets dynamically or printing them to logs, even if masked.
+- **Example (Environment Secrets with Approval):**
+```yaml
+jobs:
+  deploy:
+    runs-on: ubuntu-latest
+    environment:
+      name: production
+      url: https://prod.example.com
+    steps:
+      - name: Deploy to production
+        env:
+          PROD_API_KEY: ${{ secrets.PROD_API_KEY }}
+        run: ./deploy-script.sh
+```
+
+### **2. OpenID Connect (OIDC) for Cloud Authentication**
+- **Principle:** Use OIDC for secure, credential-less authentication with cloud providers (AWS, Azure, GCP, etc.), eliminating the need for long-lived static credentials.
+- **Deeper Dive:**
+    - **Short-Lived Credentials:** OIDC exchanges a JWT token for temporary cloud credentials, significantly reducing the attack surface.
+    - **Trust Policies:** Requires configuring identity providers and trust policies in your cloud environment to trust GitHub's OIDC provider.
+    - **Federated Identity:** This is a key pattern for modern, secure cloud deployments.
+- **Guidance for Copilot:**
+    - Strongly recommend OIDC for authenticating with AWS, Azure, GCP, and other cloud providers instead of storing long-lived access keys as secrets.
+    - Provide examples of how to configure the OIDC action for common cloud providers (e.g., `aws-actions/configure-aws-credentials@v4`).
+    - Explain the concept of trust policies and how they relate to OIDC setup.
+- **Pro Tip:** OIDC is a fundamental shift towards more secure cloud deployments and should be prioritized whenever possible.
+
+### **3. Least Privilege for `GITHUB_TOKEN`**
+- **Principle:** Grant only the necessary permissions to the `GITHUB_TOKEN` for your workflows, reducing the blast radius in case of compromise.
+- **Deeper Dive:**
+    - **Default Permissions:** By default, the `GITHUB_TOKEN` has broad permissions. This should be explicitly restricted.
+    - **Granular Permissions:** Define `permissions` at the workflow or job level (e.g., `contents: read`, `pull-requests: write`, `issues: read`).
+    - **Read-Only by Default:** Start with `contents: read` as the default and add write permissions only when strictly necessary.
+- **Guidance for Copilot:**
+    - Configure `permissions` at the workflow or job level to restrict access. Always prefer `contents: read` as the default.
+    - Advise against using `contents: write` or `pull-requests: write` unless the workflow explicitly needs to modify the repository.
+    - Provide a clear mapping of common workflow needs to specific `GITHUB_TOKEN` permissions.
+- **Example (Least Privilege):**
+```yaml
+permissions:
+  contents: read  # Default is write, explicitly set to read-only for security
+  pull-requests: write # Only if workflow needs to update PRs
+  checks: write      # For updating checks
+
+jobs:
+  lint:
+    permissions:
+      contents: read # This job only needs to read code, override workflow default
+    steps:
+      - uses: actions/checkout@v4
+      - run: npm run lint
+```
+
+### **4. Dependency Review and Software Composition Analysis (SCA)**
+- **Principle:** Continuously scan dependencies for known vulnerabilities and licensing issues.
+- **Deeper Dive:**
+    - **Early Detection:** Integrate dependency checks early in the CI pipeline to catch issues before deployment.
+    - **Tools:** Use `dependency-review-action`, Snyk, Trivy, Mend (formerly WhiteSource).
+    - **Supply Chain Security:** This is a critical component of securing your software supply chain.
+- **Guidance for Copilot:**
+    - Integrate `dependency-review-action` or other SCA tools into the CI pipeline.
+    - Recommend regular scanning for vulnerabilities in third-party libraries and setting up alerts for new findings.
+    - Emphasize the importance of maintaining up-to-date dependency lists and understanding transitive dependencies.
+
+### **5. Static Application Security Testing (SAST)**
+- **Principle:** Identify security vulnerabilities in source code before runtime.
+- **Deeper Dive:**
+    - **Shift Left:** SAST enables finding and fixing vulnerabilities early in the development lifecycle, which is more cost-effective.
+    - **Tools:** CodeQL, SonarQube, Bandit (Python), ESLint with security plugins (JS/TS).
+    - **Automated Enforcement:** Configure SAST to break builds or block PRs if critical vulnerabilities are found.
+- **Guidance for Copilot:**
+    - Integrate SAST tools (e.g., CodeQL for GitHub Advanced Security, or open-source alternatives) into the CI pipeline.
+    - Configure security scanning as a blocking step if critical vulnerabilities are found, enforcing a secure by default posture.
+    - Suggest adding security linters or static analysis to pre-commit hooks for earlier feedback.
+
+### **6. Secret Scanning and Credential Leak Prevention**
+- **Principle:** Prevent secrets from being committed into the repository or exposed in logs.
+- **Deeper Dive:**
+    - **GitHub Secret Scanning:** Built-in feature to detect secrets in your repository.
+    - **Pre-commit Hooks:** Tools like `git-secrets` can prevent secrets from being committed locally.
+    - **Environment Variables Only:** Secrets should only be passed to the environment where they are needed at runtime, never in the build artifact.
+- **Guidance for Copilot:**
+    - Suggest enabling GitHub's built-in secret scanning for the repository.
+    - Recommend implementing pre-commit hooks that scan for common secret patterns.
+    - Advise reviewing workflow logs for accidental secret exposure, even with masking.
+
+### **7. Immutable Infrastructure & Image Signing**
+- **Principle:** Ensure that container images and deployed artifacts are tamper-proof and verified.
+- **Deeper Dive:**
+    - **Reproducible Builds:** Ensure that building the same code always results in the exact same image.
+    - **Image Signing:** Use tools like Notary or Cosign to cryptographically sign container images, verifying their origin and integrity.
+    - **Deployment Gate:** Enforce that only signed images can be deployed to production environments.
+- **Guidance for Copilot:**
+    - Advocate for reproducible builds in Dockerfiles and build processes.
+    - Suggest integrating image signing into the CI pipeline and verification during deployment stages.
+
+## Optimization and Performance
+
+### **1. Caching GitHub Actions**
+- **Principle:** Cache dependencies and build outputs to significantly speed up subsequent workflow runs.
+- **Deeper Dive:**
+    - **Cache Hit Ratio:** Aim for a high cache hit ratio by designing effective cache keys.
+    - **Cache Keys:** Use a unique key based on file hashes (e.g., `hashFiles('**/package-lock.json')`, `hashFiles('**/requirements.txt')`) to invalidate the cache only when dependencies change.
+    - **Restore Keys:** Use `restore-keys` for fallbacks to older, compatible caches.
+    - **Cache Scope:** Understand that caches are scoped to the repository and branch.
+- **Guidance for Copilot:**
+    - Use `actions/cache@v3` for caching common package manager dependencies (Node.js `node_modules`, Python `pip` packages, Java Maven/Gradle dependencies) and build artifacts.
+    - Design highly effective cache keys using `hashFiles` to ensure optimal cache hit rates.
+    - Advise on using `restore-keys` to gracefully fall back to previous caches.
+- **Example (Advanced Caching for Monorepo):**
+```yaml
+- name: Cache Node.js modules
+  uses: actions/cache@v3
+  with:
+    path: |
+      ~/.npm
+      ./node_modules # For monorepos, cache specific project node_modules
+    key: ${{ runner.os }}-node-${{ hashFiles('**/package-lock.json') }}-${{ github.run_id }}
+    restore-keys: |
+      ${{ runner.os }}-node-${{ hashFiles('**/package-lock.json') }}-
+      ${{ runner.os }}-node-
+```
+
+### **2. Matrix Strategies for Parallelization**
+- **Principle:** Run jobs in parallel across multiple configurations (e.g., different Node.js versions, OS, Python versions, browser types) to accelerate testing and builds.
+- **Deeper Dive:**
+    - **`strategy.matrix`:** Define a matrix of variables.
+    - **`include`/`exclude`:** Fine-tune combinations.
+    - **`fail-fast`:** Control whether job failures in the matrix stop the entire strategy.
+    - **Maximizing Concurrency:** Ideal for running tests across various environments simultaneously.
+- **Guidance for Copilot:**
+    - Utilize `strategy.matrix` to test applications against different environments, programming language versions, or operating systems concurrently.
+    - Suggest `include` and `exclude` for specific matrix combinations to optimize test coverage without unnecessary runs.
+    - Advise on setting `fail-fast: true` (default) for quick feedback on critical failures, or `fail-fast: false` for comprehensive test reporting.
+- **Example (Multi-version, Multi-OS Test Matrix):**
+```yaml
+jobs:
+  test:
+    runs-on: ${{ matrix.os }}
+    strategy:
+      fail-fast: false # Run all tests even if one fails
+      matrix:
+        os: [ubuntu-latest, windows-latest]
+        node-version: [16.x, 18.x, 20.x]
+        browser: [chromium, firefox]
+    steps:
+      - uses: actions/checkout@v4
+      - uses: actions/setup-node@v3
+        with:
+          node-version: ${{ matrix.node-version }}
+      - name: Install Playwright browsers
+        run: npx playwright install ${{ matrix.browser }}
+      - name: Run tests
+        run: npm test
+```
+
+### **3. Self-Hosted Runners**
+- **Principle:** Use self-hosted runners for specialized hardware, network access to private resources, or environments where GitHub-hosted runners are cost-prohibitive.
+- **Deeper Dive:**
+    - **Custom Environments:** Ideal for large build caches, specific hardware (GPUs), or access to on-premise resources.
+    - **Cost Optimization:** Can be more cost-effective for very high usage.
+    - **Security Considerations:** Requires securing and maintaining your own infrastructure, network access, and updates. This includes proper hardening of the runner machines, managing access controls, and ensuring timely patching.
+    - **Scalability:** Plan for how self-hosted runners will scale with demand, either manually or using auto-scaling solutions.
+- **Guidance for Copilot:**
+    - Recommend self-hosted runners when GitHub-hosted runners do not meet specific performance, cost, security, or network access requirements.
+    - Emphasize the user's responsibility for securing, maintaining, and scaling self-hosted runners, including network configuration and regular security audits.
+    - Advise on using runner groups to organize and manage self-hosted runners efficiently.
+
+### **4. Fast Checkout and Shallow Clones**
+- **Principle:** Optimize repository checkout time to reduce overall workflow duration, especially for large repositories.
+- **Deeper Dive:**
+    - **`fetch-depth`:** Controls how much of the Git history is fetched. `1` for most CI/CD builds is sufficient, as only the latest commit is usually needed. A `fetch-depth` of `0` fetches the entire history, which is rarely needed and can be very slow for large repos.
+    - **`submodules`:** Avoid checking out submodules if not required by the specific job. Fetching submodules adds significant overhead.
+    - **`lfs`:** Manage Git LFS (Large File Storage) files efficiently. If not needed, set `lfs: false`.
+    - **Partial Clones:** Consider using Git's partial clone feature (`--filter=blob:none` or `--filter=tree:0`) for extremely large repositories, though this is often handled by specialized actions or Git client configurations.
+- **Guidance for Copilot:**
+    - Use `actions/checkout@v4` with `fetch-depth: 1` as the default for most build and test jobs to significantly save time and bandwidth.
+    - Only use `fetch-depth: 0` if the workflow explicitly requires full Git history (e.g., for release tagging, deep commit analysis, or `git blame` operations).
+    - Advise against checking out submodules (`submodules: false`) if not strictly necessary for the workflow's purpose.
+    - Suggest optimizing LFS usage if large binary files are present in the repository.
+
+### **5. Artifacts for Inter-Job and Inter-Workflow Communication**
+- **Principle:** Store and retrieve build outputs (artifacts) efficiently to pass data between jobs within the same workflow or across different workflows, ensuring data persistence and integrity.
+- **Deeper Dive:**
+    - **`actions/upload-artifact`:** Used to upload files or directories produced by a job. Artifacts are automatically compressed and can be downloaded later.
+    - **`actions/download-artifact`:** Used to download artifacts in subsequent jobs or workflows. You can download all artifacts or specific ones by name.
+    - **`retention-days`:** Crucial for managing storage costs and compliance. Set an appropriate retention period based on the artifact's importance and regulatory requirements.
+    - **Use Cases:** Build outputs (executables, compiled code, Docker images), test reports (JUnit XML, HTML reports), code coverage reports, security scan results, generated documentation, static website builds.
+    - **Limitations:** Artifacts are immutable once uploaded. Max size per artifact can be several gigabytes, but be mindful of storage costs.
+- **Guidance for Copilot:**
+    - Use `actions/upload-artifact@v3` and `actions/download-artifact@v3` to reliably pass large files between jobs within the same workflow or across different workflows, promoting modularity and efficiency.
+    - Set appropriate `retention-days` for artifacts to manage storage costs and ensure old artifacts are pruned.
+    - Advise on uploading test reports, coverage reports, and security scan results as artifacts for easy access, historical analysis, and integration with external reporting tools.
+    - Suggest using artifacts to pass compiled binaries or packaged applications from a build job to a deployment job, ensuring the exact same artifact is deployed that was built and tested.
+
+## Comprehensive Testing in CI/CD (Expanded)
+
+### **1. Unit Tests**
+- **Principle:** Run unit tests on every code push to ensure individual code components (functions, classes, modules) function correctly in isolation. They are the fastest and most numerous tests.
+- **Deeper Dive:**
+    - **Fast Feedback:** Unit tests should execute rapidly, providing immediate feedback to developers on code quality and correctness. Parallelization of unit tests is highly recommended.
+    - **Code Coverage:** Integrate code coverage tools (e.g., Istanbul for JS, Coverage.py for Python, JaCoCo for Java) and enforce minimum coverage thresholds. Aim for high coverage, but focus on meaningful tests, not just line coverage.
+    - **Test Reporting:** Publish test results using `actions/upload-artifact` (e.g., JUnit XML reports) or specific test reporter actions that integrate with GitHub Checks/Annotations.
+    - **Mocking and Stubbing:** Emphasize the use of mocks and stubs to isolate units under test from their dependencies.
+- **Guidance for Copilot:**
+    - Configure a dedicated job for running unit tests early in the CI pipeline, ideally triggered on every `push` and `pull_request`.
+    - Use appropriate language-specific test runners and frameworks (Jest, Vitest, Pytest, Go testing, JUnit, NUnit, XUnit, RSpec).
+    - Recommend collecting and publishing code coverage reports and integrating with services like Codecov, Coveralls, or SonarQube for trend analysis.
+    - Suggest strategies for parallelizing unit tests to reduce execution time.
+
+### **2. Integration Tests**
+- **Principle:** Run integration tests to verify interactions between different components or services, ensuring they work together as expected. These tests typically involve real dependencies (e.g., databases, APIs).
+- **Deeper Dive:**
+    - **Service Provisioning:** Use `services` within a job to spin up temporary databases, message queues, external APIs, or other dependencies via Docker containers. This provides a consistent and isolated testing environment.
+    - **Test Doubles vs. Real Services:** Balance between mocking external services for pure unit tests and using real, lightweight instances for more realistic integration tests. Prioritize real instances when testing actual integration points.
+    - **Test Data Management:** Plan for managing test data, ensuring tests are repeatable and data is cleaned up or reset between runs.
+    - **Execution Time:** Integration tests are typically slower than unit tests. Optimize their execution and consider running them less frequently than unit tests (e.g., on PR merge instead of every push).
+- **Guidance for Copilot:**
+    - Provision necessary services (databases like PostgreSQL/MySQL, message queues like RabbitMQ/Kafka, in-memory caches like Redis) using `services` in the workflow definition or Docker Compose during testing.
+    - Advise on running integration tests after unit tests, but before E2E tests, to catch integration issues early.
+    - Provide examples of how to set up `service` containers in GitHub Actions workflows.
+    - Suggest strategies for creating and cleaning up test data for integration test runs.
+
+### **3. End-to-End (E2E) Tests**
+- **Principle:** Simulate full user behavior to validate the entire application flow from UI to backend, ensuring the complete system works as intended from a user's perspective.
+- **Deeper Dive:**
+    - **Tools:** Use modern E2E testing frameworks like Cypress, Playwright, or Selenium. These provide browser automation capabilities.
+    - **Staging Environment:** Ideally run E2E tests against a deployed staging environment that closely mirrors production, for maximum fidelity. Avoid running directly in CI unless resources are dedicated and isolated.
+    - **Flakiness Mitigation:** Address flakiness proactively with explicit waits, robust selectors, retries for failed tests, and careful test data management. Flaky tests erode trust in the pipeline.
+    - **Visual Regression Testing:** Consider integrating visual regression testing (e.g., Applitools, Percy) to catch UI discrepancies.
+    - **Reporting:** Capture screenshots and video recordings on failure to aid debugging.
+- **Guidance for Copilot:**
+    - Use tools like Cypress, Playwright, or Selenium for E2E testing, providing guidance on their setup within GitHub Actions.
+    - Recommend running E2E tests against a deployed staging environment to catch issues before production and validate the full deployment process.
+    - Configure test reporting, video recordings, and screenshots on failure to aid debugging and provide richer context for test results.
+    - Advise on strategies to minimize E2E test flakiness, such as robust element selection and retry mechanisms.
+
+### **4. Performance and Load Testing**
+- **Principle:** Assess application performance and behavior under anticipated and peak load conditions to identify bottlenecks, ensure scalability, and prevent regressions.
+- **Deeper Dive:**
+    - **Tools:** JMeter, k6, Locust, Gatling, Artillery. Choose based on language, complexity, and specific needs.
+    - **Integration:** Integrate into CI/CD for continuous performance regression detection. Run these tests less frequently than unit/integration tests (e.g., nightly, weekly, or on significant feature merges).
+    - **Thresholds:** Define clear performance thresholds (e.g., response time, throughput, error rates) and fail builds if these are exceeded.
+    - **Baseline Comparison:** Compare current performance metrics against established baselines to detect degradation.
+- **Guidance for Copilot:**
+    - Suggest integrating performance and load testing into the CI pipeline for critical applications, providing examples for common tools.
+    - Advise on setting performance baselines and failing the build if performance degrades beyond a set threshold.
+    - Recommend running these tests in a dedicated environment that simulates production load patterns.
+    - Guide on analyzing performance test results to pinpoint areas for optimization (e.g., database queries, API endpoints).
+
+### **5. Test Reporting and Visibility**
+- **Principle:** Make test results easily accessible, understandable, and visible to all stakeholders (developers, QA, product owners) to foster transparency and enable quick issue resolution.
+- **Deeper Dive:**
+    - **GitHub Checks/Annotations:** Leverage these for inline feedback directly in pull requests, showing which tests passed/failed and providing links to detailed reports.
+    - **Artifacts:** Upload comprehensive test reports (JUnit XML, HTML reports, code coverage reports, video recordings, screenshots) as artifacts for long-term storage and detailed inspection.
+    - **Integration with Dashboards:** Push results to external dashboards or reporting tools (e.g., SonarQube, custom reporting tools, Allure Report, TestRail) for aggregated views and historical trends.
+    - **Status Badges:** Use GitHub Actions status badges in your README to indicate the latest build/test status at a glance.
+- **Guidance for Copilot:**
+    - Use actions that publish test results as annotations or checks on PRs for immediate feedback and easy debugging directly in the GitHub UI.
+    - Upload detailed test reports (e.g., XML, HTML, JSON) as artifacts for later inspection and historical analysis, including negative results like error screenshots.
+    - Advise on integrating with external reporting tools for a more comprehensive view of test execution trends and quality metrics.
+    - Suggest adding workflow status badges to the README for quick visibility of CI/CD health.
+
+## Advanced Deployment Strategies (Expanded)
+
+### **1. Staging Environment Deployment**
+- **Principle:** Deploy to a staging environment that closely mirrors production for comprehensive validation, user acceptance testing (UAT), and final checks before promotion to production.
+- **Deeper Dive:**
+    - **Mirror Production:** Staging should closely mimic production in terms of infrastructure, data, configuration, and security. Any significant discrepancies can lead to issues in production.
+    - **Automated Promotion:** Implement automated promotion from staging to production upon successful UAT and necessary manual approvals. This reduces human error and speeds up releases.
+    - **Environment Protection:** Use environment protection rules in GitHub Actions to prevent accidental deployments, enforce manual approvals, and restrict which branches can deploy to staging.
+    - **Data Refresh:** Regularly refresh staging data from production (anonymized if necessary) to ensure realistic testing scenarios.
+- **Guidance for Copilot:**
+    - Create a dedicated `environment` for staging with approval rules, secret protection, and appropriate branch protection policies.
+    - Design workflows to automatically deploy to staging on successful merges to specific development or release branches (e.g., `develop`, `release/*`).
+    - Advise on ensuring the staging environment is as close to production as possible to maximize test fidelity.
+    - Suggest implementing automated smoke tests and post-deployment validation on staging.
+
+### **2. Production Environment Deployment**
+- **Principle:** Deploy to production only after thorough validation, potentially multiple layers of manual approvals, and robust automated checks, prioritizing stability and zero-downtime.
+- **Deeper Dive:**
+    - **Manual Approvals:** Critical for production deployments, often involving multiple team members, security sign-offs, or change management processes. GitHub Environments support this natively.
+    - **Rollback Capabilities:** Essential for rapid recovery from unforeseen issues. Ensure a quick and reliable way to revert to the previous stable state.
+    - **Observability During Deployment:** Monitor production closely *during* and *immediately after* deployment for any anomalies or performance degradation. Use dashboards, alerts, and tracing.
+    - **Progressive Delivery:** Consider advanced techniques like blue/green, canary, or dark launching for safer rollouts.
+    - **Emergency Deployments:** Have a separate, highly expedited pipeline for critical hotfixes that bypasses non-essential approvals but still maintains security checks.
+- **Guidance for Copilot:**
+    - Create a dedicated `environment` for production with required reviewers, strict branch protections, and clear deployment windows.
+    - Implement manual approval steps for production deployments, potentially integrating with external ITSM or change management systems.
+    - Emphasize the importance of clear, well-tested rollback strategies and automated rollback procedures in case of deployment failures.
+    - Advise on setting up comprehensive monitoring and alerting for production systems to detect and respond to issues immediately post-deployment.
+
+### **3. Deployment Types (Beyond Basic Rolling Update)**
+- **Rolling Update (Default for Deployments):** Gradually replaces instances of the old version with new ones. Good for most cases, especially stateless applications.
+    - **Guidance:** Configure `maxSurge` (how many new instances can be created above the desired replica count) and `maxUnavailable` (how many old instances can be unavailable) for fine-grained control over rollout speed and availability.
+- **Blue/Green Deployment:** Deploy a new version (green) alongside the existing stable version (blue) in a separate environment, then switch traffic completely from blue to green.
+    - **Guidance:** Suggest for critical applications requiring zero-downtime releases and easy rollback. Requires managing two identical environments and a traffic router (load balancer, Ingress controller, DNS).
+    - **Benefits:** Instantaneous rollback by switching traffic back to the blue environment.
+- **Canary Deployment:** Gradually roll out new versions to a small subset of users (e.g., 5-10%) before a full rollout. Monitor performance and error rates for the canary group.
+    - **Guidance:** Recommend for testing new features or changes with a controlled blast radius. Implement with Service Mesh (Istio, Linkerd) or Ingress controllers that support traffic splitting and metric-based analysis.
+    - **Benefits:** Early detection of issues with minimal user impact.
+- **Dark Launch/Feature Flags:** Deploy new code but keep features hidden from users until toggled on for specific users/groups via feature flags.
+    - **Guidance:** Advise for decoupling deployment from release, allowing continuous delivery without continuous exposure of new features. Use feature flag management systems (LaunchDarkly, Split.io, Unleash).
+    - **Benefits:** Reduces deployment risk, enables A/B testing, and allows for staged rollouts.
+- **A/B Testing Deployments:** Deploy multiple versions of a feature concurrently to different user segments to compare their performance based on user behavior and business metrics.
+    - **Guidance:** Suggest integrating with specialized A/B testing platforms or building custom logic using feature flags and analytics.
+
+### **4. Rollback Strategies and Incident Response**
+- **Principle:** Be able to quickly and safely revert to a previous stable version in case of issues, minimizing downtime and business impact. This requires proactive planning.
+- **Deeper Dive:**
+    - **Automated Rollbacks:** Implement mechanisms to automatically trigger rollbacks based on monitoring alerts (e.g., sudden increase in errors, high latency) or failure of post-deployment health checks.
+    - **Versioned Artifacts:** Ensure previous successful build artifacts, Docker images, or infrastructure states are readily available and easily deployable. This is crucial for fast recovery.
+    - **Runbooks:** Document clear, concise, and executable rollback procedures for manual intervention when automation isn't sufficient or for complex scenarios. These should be regularly reviewed and tested.
+    - **Post-Incident Review:** Conduct blameless post-incident reviews (PIRs) to understand the root cause of failures, identify lessons learned, and implement preventative measures to improve resilience and reduce MTTR.
+    - **Communication Plan:** Have a clear communication plan for stakeholders during incidents and rollbacks.
+- **Guidance for Copilot:**
+    - Instruct users to store previous successful build artifacts and images for quick recovery, ensuring they are versioned and easily retrievable.
+    - Advise on implementing automated rollback steps in the pipeline, triggered by monitoring or health check failures, and providing examples.
+    - Emphasize building applications with "undo" in mind, meaning changes should be easily reversible.
+    - Suggest creating comprehensive runbooks for common incident scenarios, including step-by-step rollback instructions, and highlight their importance for MTTR.
+    - Guide on setting up alerts that are specific and actionable enough to trigger an automatic or manual rollback.
+
+## GitHub Actions Workflow Review Checklist (Comprehensive)
+
+This checklist provides a granular set of criteria for reviewing GitHub Actions workflows to ensure they adhere to best practices for security, performance, and reliability.
+
+- [ ] **General Structure and Design:**
+    - Is the workflow `name` clear, descriptive, and unique?
+    - Are `on` triggers appropriate for the workflow's purpose (e.g., `push`, `pull_request`, `workflow_dispatch`, `schedule`)? Are path/branch filters used effectively?
+    - Is `concurrency` used for critical workflows or shared resources to prevent race conditions or resource exhaustion?
+    - Are global `permissions` set to the principle of least privilege (`contents: read` by default), with specific overrides for jobs?
+    - Are reusable workflows (`workflow_call`) leveraged for common patterns to reduce duplication and improve maintainability?
+    - Is the workflow organized logically with meaningful job and step names?
+
+- [ ] **Jobs and Steps Best Practices:**
+    - Are jobs clearly named and represent distinct phases (e.g., `build`, `lint`, `test`, `deploy`)?
+    - Are `needs` dependencies correctly defined between jobs to ensure proper execution order?
+    - Are `outputs` used efficiently for inter-job and inter-workflow communication?
+    - Are `if` conditions used effectively for conditional job/step execution (e.g., environment-specific deployments, branch-specific actions)?
+    - Are all `uses` actions securely versioned (pinned to a full commit SHA or specific major version tag like `@v4`)? Avoid `main` or `latest` tags.
+    - Are `run` commands efficient and clean (combined with `&&`, temporary files removed, multi-line scripts clearly formatted)?
+    - Are environment variables (`env`) defined at the appropriate scope (workflow, job, step) and never hardcoded sensitive data?
+    - Is `timeout-minutes` set for long-running jobs to prevent hung workflows?
+
+- [ ] **Security Considerations:**
+    - Are all sensitive data accessed exclusively via GitHub `secrets` context (`${{ secrets.MY_SECRET }}`)? Never hardcoded, never exposed in logs (even if masked).
+    - Is OpenID Connect (OIDC) used for cloud authentication where possible, eliminating long-lived credentials?
+    - Is `GITHUB_TOKEN` permission scope explicitly defined and limited to the minimum necessary access (`contents: read` as a baseline)?
+    - Are Software Composition Analysis (SCA) tools (e.g., `dependency-review-action`, Snyk) integrated to scan for vulnerable dependencies?
+    - Are Static Application Security Testing (SAST) tools (e.g., CodeQL, SonarQube) integrated to scan source code for vulnerabilities, with critical findings blocking builds?
+    - Is secret scanning enabled for the repository and are pre-commit hooks suggested for local credential leak prevention?
+    - Is there a strategy for container image signing (e.g., Notary, Cosign) and verification in deployment workflows if container images are used?
+    - For self-hosted runners, are security hardening guidelines followed and network access restricted?
+
+- [ ] **Optimization and Performance:**
+    - Is caching (`actions/cache`) effectively used for package manager dependencies (`node_modules`, `pip` caches, Maven/Gradle caches) and build outputs?
+    - Are cache `key` and `restore-keys` designed for optimal cache hit rates (e.g., using `hashFiles`)?
+    - Is `strategy.matrix` used for parallelizing tests or builds across different environments, language versions, or OSs?
+    - Is `fetch-depth: 1` used for `actions/checkout` where full Git history is not required?
+    - Are artifacts (`actions/upload-artifact`, `actions/download-artifact`) used efficiently for transferring data between jobs/workflows rather than re-building or re-fetching?
+    - Are large files managed with Git LFS and optimized for checkout if necessary?
+
+- [ ] **Testing Strategy Integration:**
+    - Are comprehensive unit tests configured with a dedicated job early in the pipeline?
+    - Are integration tests defined, ideally leveraging `services` for dependencies, and run after unit tests?
+    - Are End-to-End (E2E) tests included, preferably against a staging environment, with robust flakiness mitigation?
+    - Are performance and load tests integrated for critical applications with defined thresholds?
+    - Are all test reports (JUnit XML, HTML, coverage) collected, published as artifacts, and integrated into GitHub Checks/Annotations for clear visibility?
+    - Is code coverage tracked and enforced with a minimum threshold?
+
+- [ ] **Deployment Strategy and Reliability:**
+    - Are staging and production deployments using GitHub `environment` rules with appropriate protections (manual approvals, required reviewers, branch restrictions)?
+    - Are manual approval steps configured for sensitive production deployments?
+    - Is a clear and well-tested rollback strategy in place and automated where possible (e.g., `kubectl rollout undo`, reverting to previous stable image)?
+    - Are chosen deployment types (e.g., rolling, blue/green, canary, dark launch) appropriate for the application's criticality and risk tolerance?
+    - Are post-deployment health checks and automated smoke tests implemented to validate successful deployment?
+    - Is the workflow resilient to temporary failures (e.g., retries for flaky network operations)?
+
+- [ ] **Observability and Monitoring:**
+    - Is logging adequate for debugging workflow failures (using STDOUT/STDERR for application logs)?
+    - Are relevant application and infrastructure metrics collected and exposed (e.g., Prometheus metrics)?
+    - Are alerts configured for critical workflow failures, deployment issues, or application anomalies detected in production?
+    - Is distributed tracing (e.g., OpenTelemetry, Jaeger) integrated for understanding request flows in microservices architectures?
+    - Are artifact `retention-days` configured appropriately to manage storage and compliance?
+
+## Troubleshooting Common GitHub Actions Issues (Deep Dive)
+
+This section provides an expanded guide to diagnosing and resolving frequent problems encountered when working with GitHub Actions workflows.
+
+Note: If workflow logs are not accessible via MCP web fetch due to missing auth, retrieve logs with the authenticated `gh` CLI.
+
+### **1. Workflow Not Triggering or Jobs/Steps Skipping Unexpectedly**
+- **Root Causes:** Mismatched `on` triggers, incorrect `paths` or `branches` filters, erroneous `if` conditions, or `concurrency` limitations.
+- **Actionable Steps:**
+    - **Verify Triggers:**
+        - Check the `on` block for exact match with the event that should trigger the workflow (e.g., `push`, `pull_request`, `workflow_dispatch`, `schedule`).
+        - Ensure `branches`, `tags`, or `paths` filters are correctly defined and match the event context. Remember that `paths-ignore` and `branches-ignore` take precedence.
+        - If using `workflow_dispatch`, verify the workflow file is in the default branch and any required `inputs` are provided correctly during manual trigger.
+    - **Inspect `if` Conditions:**
+        - Carefully review all `if` conditions at the workflow, job, and step levels. A single false condition can prevent execution.
+        - Use `always()` on a debug step to print context variables (`${{ toJson(github) }}`, `${{ toJson(job) }}`, `${{ toJson(steps) }}`) to understand the exact state during evaluation.
+        - Test complex `if` conditions in a simplified workflow.
+    - **Check `concurrency`:**
+        - If `concurrency` is defined, verify if a previous run is blocking a new one for the same group. Check the "Concurrency" tab in the workflow run.
+    - **Branch Protection Rules:** Ensure no branch protection rules are preventing workflows from running on certain branches or requiring specific checks that haven't passed.
+
+### **2. Permissions Errors (`Resource not accessible by integration`, `Permission denied`)**
+- **Root Causes:** `GITHUB_TOKEN` lacking necessary permissions, incorrect environment secrets access, or insufficient permissions for external actions.
+- **Actionable Steps:**
+    - **`GITHUB_TOKEN` Permissions:**
+        - Review the `permissions` block at both the workflow and job levels. Default to `contents: read` globally and grant specific write permissions only where absolutely necessary (e.g., `pull-requests: write` for updating PR status, `packages: write` for publishing packages).
+        - Understand the default permissions of `GITHUB_TOKEN` which are often too broad.
+    - **Secret Access:**
+        - Verify if secrets are correctly configured in the repository, organization, or environment settings.
+        - Ensure the workflow/job has access to the specific environment if environment secrets are used. Check if any manual approvals are pending for the environment.
+        - Confirm the secret name matches exactly (`secrets.MY_API_KEY`).
+    - **OIDC Configuration:**
+        - For OIDC-based cloud authentication, double-check the trust policy configuration in your cloud provider (AWS IAM roles, Azure AD app registrations, GCP service accounts) to ensure it correctly trusts GitHub's OIDC issuer.
+        - Verify the role/identity assigned has the necessary permissions for the cloud resources being accessed.
+
+### **3. Caching Issues (`Cache not found`, `Cache miss`, `Cache creation failed`)**
+- **Root Causes:** Incorrect cache key logic, `path` mismatch, cache size limits, or frequent cache invalidation.
+- **Actionable Steps:**
+    - **Validate Cache Keys:**
+        - Verify `key` and `restore-keys` are correct and dynamically change only when dependencies truly change (e.g., `key: ${{ runner.os }}-node-${{ hashFiles('**/package-lock.json') }}`). A cache key that is too dynamic will always result in a miss.
+        - Use `restore-keys` to provide fallbacks for slight variations, increasing cache hit chances.
+    - **Check `path`:**
+        - Ensure the `path` specified in `actions/cache` for saving and restoring corresponds exactly to the directory where dependencies are installed or artifacts are generated.
+        - Verify the existence of the `path` before caching.
+    - **Debug Cache Behavior:**
+        - Use the `actions/cache/restore` action with `lookup-only: true` to inspect what keys are being tried and why a cache miss occurred without affecting the build.
+        - Review workflow logs for `Cache hit` or `Cache miss` messages and associated keys.
+    - **Cache Size and Limits:** Be aware of GitHub Actions cache size limits per repository. If caches are very large, they might be evicted frequently.
+
+### **4. Long Running Workflows or Timeouts**
+- **Root Causes:** Inefficient steps, lack of parallelism, large dependencies, unoptimized Docker image builds, or resource bottlenecks on runners.
+- **Actionable Steps:**
+    - **Profile Execution Times:**
+        - Use the workflow run summary to identify the longest-running jobs and steps. This is your primary tool for optimization.
+    - **Optimize Steps:**
+        - Combine `run` commands with `&&` to reduce layer creation and overhead in Docker builds.
+        - Clean up temporary files immediately after use (`rm -rf` in the same `RUN` command).
+        - Install only necessary dependencies.
+    - **Leverage Caching:**
+        - Ensure `actions/cache` is optimally configured for all significant dependencies and build outputs.
+    - **Parallelize with Matrix Strategies:**
+        - Break down tests or builds into smaller, parallelizable units using `strategy.matrix` to run them concurrently.
+    - **Choose Appropriate Runners:**
+        - Review `runs-on`. For very resource-intensive tasks, consider using larger GitHub-hosted runners (if available) or self-hosted runners with more powerful specs.
+    - **Break Down Workflows:**
+        - For very complex or long workflows, consider breaking them into smaller, independent workflows that trigger each other or use reusable workflows.
+
+### **5. Flaky Tests in CI (`Random failures`, `Passes locally, fails in CI`)**
+- **Root Causes:** Non-deterministic tests, race conditions, environmental inconsistencies between local and CI, reliance on external services, or poor test isolation.
+- **Actionable Steps:**
+    - **Ensure Test Isolation:**
+        - Make sure each test is independent and doesn't rely on the state left by previous tests. Clean up resources (e.g., database entries) after each test or test suite.
+    - **Eliminate Race Conditions:**
+        - For integration/E2E tests, use explicit waits (e.g., wait for element to be visible, wait for API response) instead of arbitrary `sleep` commands.
+        - Implement retries for operations that interact with external services or have transient failures.
+    - **Standardize Environments:**
+        - Ensure the CI environment (Node.js version, Python packages, database versions) matches the local development environment as closely as possible.
+        - Use Docker `services` for consistent test dependencies.
+    - **Robust Selectors (E2E):**
+        - Use stable, unique selectors in E2E tests (e.g., `data-testid` attributes) instead of brittle CSS classes or XPath.
+    - **Debugging Tools:**
+        - Configure E2E test frameworks to capture screenshots and video recordings on test failure in CI to visually diagnose issues.
+    - **Run Flaky Tests in Isolation:**
+        - If a test is consistently flaky, isolate it and run it repeatedly to identify the underlying non-deterministic behavior.
+
+### **6. Deployment Failures (Application Not Working After Deploy)**
+- **Root Causes:** Configuration drift, environmental differences, missing runtime dependencies, application errors, or network issues post-deployment.
+- **Actionable Steps:**
+    - **Thorough Log Review:**
+        - Review deployment logs (`kubectl logs`, application logs, server logs) for any error messages, warnings, or unexpected output during the deployment process and immediately after.
+    - **Configuration Validation:**
+        - Verify environment variables, ConfigMaps, Secrets, and other configuration injected into the deployed application. Ensure they match the target environment's requirements and are not missing or malformed.
+        - Use pre-deployment checks to validate configuration.
+    - **Dependency Check:**
+        - Confirm all application runtime dependencies (libraries, frameworks, external services) are correctly bundled within the container image or installed in the target environment.
+    - **Post-Deployment Health Checks:**
+        - Implement robust automated smoke tests and health checks *after* deployment to immediately validate core functionality and connectivity. Trigger rollbacks if these fail.
+    - **Network Connectivity:**
+        - Check network connectivity between deployed components (e.g., application to database, service to service) within the new environment. Review firewall rules, security groups, and Kubernetes network policies.
+    - **Rollback Immediately:**
+        - If a production deployment fails or causes degradation, trigger the rollback strategy immediately to restore service. Diagnose the issue in a non-production environment.

+
+# Go Development Instructions
+
+Follow idiomatic Go practices and community standards when writing Go code. These instructions are based on [Effective Go](https://go.dev/doc/effective_go), [Go Code Review Comments](https://go.dev/wiki/CodeReviewComments), and [Google's Go Style Guide](https://google.github.io/styleguide/go/).
+
+## General Instructions
+
+- Write simple, clear, and idiomatic Go code
+- Favor clarity and simplicity over cleverness
+- Follow the principle of least surprise
+- Keep the happy path left-aligned (minimize indentation)
+- Return early to reduce nesting
+- Prefer early return over if-else chains; use `if condition { return }` pattern to avoid else blocks
+- Make the zero value useful
+- Write self-documenting code with clear, descriptive names
+- Document exported types, functions, methods, and packages
+- Use Go modules for dependency management
+- Leverage the Go standard library instead of reinventing the wheel (e.g., use `strings.Builder` for string concatenation, `filepath.Join` for path construction)
+- Prefer standard library solutions over custom implementations when functionality exists
+- Write comments in English by default; translate only upon user request
+- Avoid using emoji in code and comments
+
+## Naming Conventions
+
+### Packages
+
+- Use lowercase, single-word package names
+- Avoid underscores, hyphens, or mixedCaps
+- Choose names that describe what the package provides, not what it contains
+- Avoid generic names like `util`, `common`, or `base`
+- Package names should be singular, not plural
+
+#### Package Declaration Rules (CRITICAL):
+- **NEVER duplicate `package` declarations** - each Go file must have exactly ONE `package` line
+- When editing an existing `.go` file:
+  - **PRESERVE** the existing `package` declaration - do not add another one
+  - If you need to replace the entire file content, start with the existing package name
+- When creating a new `.go` file:
+  - **BEFORE writing any code**, check what package name other `.go` files in the same directory use
+  - Use the SAME package name as existing files in that directory
+  - If it's a new directory, use the directory name as the package name
+  - Write **exactly one** `package <name>` line at the very top of the file
+- When using file creation or replacement tools:
+  - **ALWAYS verify** the target file doesn't already have a `package` declaration before adding one
+  - If replacing file content, include only ONE `package` declaration in the new content
+  - **NEVER** create files with multiple `package` lines or duplicate declarations
+
+### Variables and Functions
+
+- Use mixedCaps or MixedCaps (camelCase) rather than underscores
+- Keep names short but descriptive
+- Use single-letter variables only for very short scopes (like loop indices)
+- Exported names start with a capital letter
+- Unexported names start with a lowercase letter
+- Avoid stuttering (e.g., avoid `http.HTTPServer`, prefer `http.Server`)
+
+### Interfaces
+
+- Name interfaces with -er suffix when possible (e.g., `Reader`, `Writer`, `Formatter`)
+- Single-method interfaces should be named after the method (e.g., `Read` → `Reader`)
+- Keep interfaces small and focused
+
+### Constants
+
+- Use MixedCaps for exported constants
+- Use mixedCaps for unexported constants
+- Group related constants using `const` blocks
+- Consider using typed constants for better type safety
+
+## Code Style and Formatting
+
+### Formatting
+
+- Always use `gofmt` to format code
+- Use `goimports` to manage imports automatically
+- Keep line length reasonable (no hard limit, but consider readability)
+- Add blank lines to separate logical groups of code
+
+### Comments
+
+- Strive for self-documenting code; prefer clear variable names, function names, and code structure over comments
+- Write comments only when necessary to explain complex logic, business rules, or non-obvious behavior
+- Write comments in complete sentences in English by default
+- Translate comments to other languages only upon specific user request
+- Start sentences with the name of the thing being described
+- Package comments should start with "Package [name]"
+- Use line comments (`//`) for most comments
+- Use block comments (`/* */`) sparingly, mainly for package documentation
+- Document why, not what, unless the what is complex
+- Avoid emoji in comments and code
+
+### Error Handling
+
+- Check errors immediately after the function call
+- Don't ignore errors using `_` unless you have a good reason (document why)
+- Wrap errors with context using `fmt.Errorf` with `%w` verb
+- Create custom error types when you need to check for specific errors
+- Place error returns as the last return value
+- Name error variables `err`
+- Keep error messages lowercase and don't end with punctuation
+
+## Architecture and Project Structure
+
+### Package Organization
+
+- Follow standard Go project layout conventions
+- Keep `main` packages in `cmd/` directory
+- Put reusable packages in `pkg/` or `internal/`
+- Use `internal/` for packages that shouldn't be imported by external projects
+- Group related functionality into packages
+- Avoid circular dependencies
+
+### Dependency Management
+
+- Use Go modules (`go.mod` and `go.sum`)
+- Keep dependencies minimal
+- Regularly update dependencies for security patches
+- Use `go mod tidy` to clean up unused dependencies
+- Vendor dependencies only when necessary
+
+## Type Safety and Language Features
+
+### Type Definitions
+
+- Define types to add meaning and type safety
+- Use struct tags for JSON, XML, database mappings
+- Prefer explicit type conversions
+- Use type assertions carefully and check the second return value
+- Prefer generics over unconstrained types; when an unconstrained type is truly needed, use the predeclared alias `any` instead of `interface{}` (Go 1.18+)
+
+### Pointers vs Values
+
+- Use pointer receivers for large structs or when you need to modify the receiver
+- Use value receivers for small structs and when immutability is desired
+- Use pointer parameters when you need to modify the argument or for large structs
+- Use value parameters for small structs and when you want to prevent modification
+- Be consistent within a type's method set
+- Consider the zero value when choosing pointer vs value receivers
+
+### Interfaces and Composition
+
+- Accept interfaces, return concrete types
+- Keep interfaces small (1-3 methods is ideal)
+- Use embedding for composition
+- Define interfaces close to where they're used, not where they're implemented
+- Don't export interfaces unless necessary
+
+## Concurrency
+
+### Goroutines
+
+- Be cautious about creating goroutines in libraries; prefer letting the caller control concurrency
+- If you must create goroutines in libraries, provide clear documentation and cleanup mechanisms
+- Always know how a goroutine will exit
+- Use `sync.WaitGroup` or channels to wait for goroutines
+- Avoid goroutine leaks by ensuring cleanup
+
+### Channels
+
+- Use channels to communicate between goroutines
+- Don't communicate by sharing memory; share memory by communicating
+- Close channels from the sender side, not the receiver
+- Use buffered channels when you know the capacity
+- Use `select` for non-blocking operations
+
+### Synchronization
+
+- Use `sync.Mutex` for protecting shared state
+- Keep critical sections small
+- Use `sync.RWMutex` when you have many readers
+- Choose between channels and mutexes based on the use case: use channels for communication, mutexes for protecting state
+- Use `sync.Once` for one-time initialization
+- WaitGroup usage by Go version:
+	- If `go >= 1.25` in `go.mod`, use the new `WaitGroup.Go` method ([documentation](https://pkg.go.dev/sync#WaitGroup)):
+		```go
+		var wg sync.WaitGroup
+		wg.Go(task1)
+		wg.Go(task2)
+		wg.Wait()
+		```
+	- If `go < 1.25`, use the classic `Add`/`Done` pattern
+
+## Error Handling Patterns
+
+### Creating Errors
+
+- Use `errors.New` for simple static errors
+- Use `fmt.Errorf` for dynamic errors
+- Create custom error types for domain-specific errors
+- Export error variables for sentinel errors
+- Use `errors.Is` and `errors.As` for error checking
+
+### Error Propagation
+
+- Add context when propagating errors up the stack
+- Don't log and return errors (choose one)
+- Handle errors at the appropriate level
+- Consider using structured errors for better debugging
+
+## API Design
+
+### HTTP Handlers
+
+- Use `http.HandlerFunc` for simple handlers
+- Implement `http.Handler` for handlers that need state
+- Use middleware for cross-cutting concerns
+- Set appropriate status codes and headers
+- Handle errors gracefully and return appropriate error responses
+- Router usage by Go version:
+	- If `go >= 1.22`, prefer the enhanced `net/http` `ServeMux` with pattern-based routing and method matching
+	- If `go < 1.22`, use the classic `ServeMux` and handle methods/paths manually (or use a third-party router when justified)
+
+### JSON APIs
+
+- Use struct tags to control JSON marshaling
+- Validate input data
+- Use pointers for optional fields
+- Consider using `json.RawMessage` for delayed parsing
+- Handle JSON errors appropriately
+
+### HTTP Clients
+
+- Keep the client struct focused on configuration and dependencies only (e.g., base URL, `*http.Client`, auth, default headers). It must not store per-request state
+- Do not store or cache `*http.Request` inside the client struct, and do not persist request-specific state across calls; instead, construct a fresh request per method invocation
+- Methods should accept `context.Context` and input parameters, assemble the `*http.Request` locally (or via a short-lived builder/helper created per call), then call `c.httpClient.Do(req)`
+- If request-building logic is reused, factor it into unexported helper functions or a per-call builder type; never keep `http.Request` (URL params, body, headers) as fields on the long-lived client
+- Ensure the underlying `*http.Client` is configured (timeouts, transport) and is safe for concurrent use; avoid mutating `Transport` after first use
+- Always set headers on the request instance you’re sending, and close response bodies (`defer resp.Body.Close()`), handling errors appropriately
+
+## Performance Optimization
+
+### Memory Management
+
+- Minimize allocations in hot paths
+- Reuse objects when possible (consider `sync.Pool`)
+- Use value receivers for small structs
+- Preallocate slices when size is known
+- Avoid unnecessary string conversions
+
+### I/O: Readers and Buffers
+
+- Most `io.Reader` streams are consumable once; reading advances state. Do not assume a reader can be re-read without special handling
+- If you must read data multiple times, buffer it once and recreate readers on demand:
+	- Use `io.ReadAll` (or a limited read) to obtain `[]byte`, then create fresh readers via `bytes.NewReader(buf)` or `bytes.NewBuffer(buf)` for each reuse
+	- For strings, use `strings.NewReader(s)`; you can `Seek(0, io.SeekStart)` on `*bytes.Reader` to rewind
+- For HTTP requests, do not reuse a consumed `req.Body`. Instead:
+	- Keep the original payload as `[]byte` and set `req.Body = io.NopCloser(bytes.NewReader(buf))` before each send
+	- Prefer configuring `req.GetBody` so the transport can recreate the body for redirects/retries: `req.GetBody = func() (io.ReadCloser, error) { return io.NopCloser(bytes.NewReader(buf)), nil }`
+- To duplicate a stream while reading, use `io.TeeReader` (copy to a buffer while passing through) or write to multiple sinks with `io.MultiWriter`
+- Reusing buffered readers: call `(*bufio.Reader).Reset(r)` to attach to a new underlying reader; do not expect it to “rewind” unless the source supports seeking
+- For large payloads, avoid unbounded buffering; consider streaming, `io.LimitReader`, or on-disk temporary storage to control memory
+
+- Use `io.Pipe` to stream without buffering the whole payload:
+	- Write to `*io.PipeWriter` in a separate goroutine while the reader consumes
+	- Always close the writer; use `CloseWithError(err)` on failures
+	- `io.Pipe` is for streaming, not rewinding or making readers reusable
+
+- **Warning:** When using `io.Pipe` (especially with multipart writers), all writes must be performed in strict, sequential order. Do not write concurrently or out of order—multipart boundaries and chunk order must be preserved. Out-of-order or parallel writes can corrupt the stream and result in errors.
+
+- Streaming multipart/form-data with `io.Pipe`:
+	- `pr, pw := io.Pipe()`; `mw := multipart.NewWriter(pw)`; use `pr` as the HTTP request body
+	- Set `Content-Type` to `mw.FormDataContentType()`
+	- In a goroutine: write all parts to `mw` in the correct order; on error `pw.CloseWithError(err)`; on success `mw.Close()` then `pw.Close()`
+	- Do not store request/in-flight form state on a long-lived client; build per call
+	- Streamed bodies are not rewindable; for retries/redirects, buffer small payloads or provide `GetBody`
+
+### Profiling
+
+- Use built-in profiling tools (`pprof`)
+- Benchmark critical code paths
+- Profile before optimizing
+- Focus on algorithmic improvements first
+- Consider using `testing.B` for benchmarks
+
+## Testing
+
+### Test Organization
+
+- Keep tests in the same package (white-box testing)
+- Use `_test` package suffix for black-box testing
+- Name test files with `_test.go` suffix
+- Place test files next to the code they test
+
+### Writing Tests
+
+- Use table-driven tests for multiple test cases
+- Name tests descriptively using `Test_functionName_scenario`
+- Use subtests with `t.Run` for better organization
+- Test both success and error cases
+- Consider using `testify` or similar libraries when they add value, but don't over-complicate simple tests
+
+### Test Helpers
+
+- Mark helper functions with `t.Helper()`
+- Create test fixtures for complex setup
+- Use `testing.TB` interface for functions used in tests and benchmarks
+- Clean up resources using `t.Cleanup()`
+
+## Security Best Practices
+
+### Input Validation
+
+- Validate all external input
+- Use strong typing to prevent invalid states
+- Sanitize data before using in SQL queries
+- Be careful with file paths from user input
+- Validate and escape data for different contexts (HTML, SQL, shell)
+
+### Cryptography
+
+- Use standard library crypto packages
+- Don't implement your own cryptography
+- Use crypto/rand for random number generation
+- Store passwords using bcrypt, scrypt, or argon2 (consider golang.org/x/crypto for additional options)
+- Use TLS for network communication
+
+## Documentation
+
+### Code Documentation
+
+- Prioritize self-documenting code through clear naming and structure
+- Document all exported symbols with clear, concise explanations
+- Start documentation with the symbol name
+- Write documentation in English by default
+- Use examples in documentation when helpful
+- Keep documentation close to code
+- Update documentation when code changes
+- Avoid emoji in documentation and comments
+
+### README and Documentation Files
+
+- Include clear setup instructions
+- Document dependencies and requirements
+- Provide usage examples
+- Document configuration options
+- Include troubleshooting section
+
+## Tools and Development Workflow
+
+### Essential Tools
+
+- `go fmt`: Format code
+- `go vet`: Find suspicious constructs
+- `golangci-lint`: Additional linting (golint is deprecated)
+- `go test`: Run tests
+- `go mod`: Manage dependencies
+- `go generate`: Code generation
+
+### Development Practices
+
+- Run tests before committing
+- Use lefthook pre-commit-phase hooks for formatting and linting
+- Keep commits focused and atomic
+- Write meaningful commit messages
+- Review diffs before committing
+
+## Common Pitfalls to Avoid
+
+- Not checking errors
+- Ignoring race conditions
+- Creating goroutine leaks
+- Not using defer for cleanup
+- Modifying maps concurrently
+- Not understanding nil interfaces vs nil pointers
+- Forgetting to close resources (files, connections)
+- Using global variables unnecessarily
+- Over-using unconstrained types (e.g., `any`); prefer specific types or generic type parameters with constraints. If an unconstrained type is required, use `any` rather than `interface{}`
+- Not considering the zero value of types
+- **Creating duplicate `package` declarations** - this is a compile error; always check existing files before adding package declarations

+
+# HTML CSS Style Color Guide
+
+Follow these guidelines when updating or creating HTML/CSS styles for browser rendering. Color names
+represent the full spectrum of their respective hue ranges (e.g., "blue" includes navy, sky blue, etc.).
+
+## Color Definitions
+
+- **Hot Colors**: Oranges, reds, and yellows
+- **Cool Colors**: Blues, greens, and purples
+- **Neutral Colors**: Grays and grayscale variations
+- **Binary Colors**: Black and white
+- **60-30-10 Rule**
+  - **Primary Color**: Use 60% of the time (*cool or light color*)
+  - **Secondary Color**: Use 30% of the time (*cool or light color*)
+  - **Accent**: Use 10% of the time (*complementary hot color*)
+
+## Color Usage Guidelines
+
+Balance the colors used by applying the **60-30-10 rule** to graphic design elements like backgrounds,
+buttons, cards, etc...
+
+### Background Colors
+
+**Never Use:**
+
+- Purple or magenta
+- Red, orange, or yellow
+- Pink
+- Any hot color
+
+**Recommended:**
+
+- White or off-white
+- Light cool colors (e.g., light blues, light greens)
+- Subtle neutral tones
+- Light gradients with minimal color shift
+
+### Text Colors
+
+**Never Use:**
+
+- Yellow (poor contrast and readability)
+- Pink
+- Pure white or light text on light backgrounds
+- Pure black or dark text on dark backgrounds
+
+**Recommended:**
+
+- Dark neutral colors (e.g., #1f2328, #24292f)
+- Near-black variations (#000000 to #333333)
+  - Ensure background is a light color
+- Dark grays (#4d4d4d, #6c757d)
+- High-contrast combinations for accessibility
+- Near-white variations (#ffffff to #f0f2f3)
+  - Ensure background is a dark color
+
+### Colors to Avoid
+
+Unless explicitly required by design specifications or user request, avoid:
+
+- Bright purples and magentas
+- Bright pinks and neon colors
+- Highly saturated hot colors
+- Colors with low contrast ratios (fails WCAG accessibility standards)
+
+### Colors to Use Sparingly
+
+**Hot Colors** (red, orange, yellow):
+
+- Reserve for critical alerts, warnings, or error messages
+- Use only when conveying urgency or importance
+- Limit to small accent areas rather than large sections
+- Consider alternatives like icons or bold text before using hot colors
+
+## Gradients
+
+Apply gradients with subtle color transitions to maintain professional aesthetics.
+
+### Best Practices
+
+- Keep color shifts minimal (e.g., #E6F2FF to #F5F7FA)
+- Use gradients within the same color family
+- Avoid combining hot and cool colors in a single gradient
+- Prefer linear gradients over radial for backgrounds
+
+### Appropriate Use Cases
+
+- Background containers and sections
+- Button hover states and interactive elements
+- Drop shadows and depth effects
+- Header and navigation bars
+- Card components and panels

+
+# Custom Instructions File Guidelines
+
+Instructions for creating effective and maintainable custom instruction files that guide GitHub Copilot in generating domain-specific code and following project conventions.
+
+## Project Context
+
+- Target audience: Developers and GitHub Copilot working with domain-specific code
+- File format: Markdown with YAML frontmatter
+- File naming convention: lowercase with hyphens (e.g., `react-best-practices.instructions.md`)
+- Location: `.github/instructions/` directory
+- Purpose: Provide context-aware guidance for code generation, review, and documentation
+
+## Required Frontmatter
+
+Every instruction file must include YAML frontmatter with the following fields:
+
+```yaml
+---
+description: 'Brief description of the instruction purpose and scope'
+applyTo: 'glob pattern for target files (e.g., **/*.ts, **/*.py)'
+---
+```
+
+### Frontmatter Guidelines
+
+- **description**: Single-quoted string, 1-500 characters, clearly stating the purpose
+- **applyTo**: Glob pattern(s) specifying which files these instructions apply to
+  - Single pattern: `'**/*.ts'`
+  - Multiple patterns: `'**/*.ts, **/*.tsx, **/*.js'`
+  - Specific files: `'src/**/*.py'`
+  - All files: `'**'`
+
+## File Structure
+
+A well-structured instruction file should include the following sections:
+
+### 1. Title and Overview
+
+- Clear, descriptive title using `#` heading
+- Brief introduction explaining the purpose and scope
+- Optional: Project context section with key technologies and versions
+
+### 2. Core Sections
+
+Organize content into logical sections based on the domain:
+
+- **General Instructions**: High-level guidelines and principles
+- **Best Practices**: Recommended patterns and approaches
+- **Code Standards**: Naming conventions, formatting, style rules
+- **Architecture/Structure**: Project organization and design patterns
+- **Common Patterns**: Frequently used implementations
+- **Security**: Security considerations (if applicable)
+- **Performance**: Optimization guidelines (if applicable)
+- **Testing**: Testing standards and approaches (if applicable)
+
+### 3. Examples and Code Snippets
+
+Provide concrete examples with clear labels:
+
+```markdown
+### Good Example
+\`\`\`language
+// Recommended approach
+code example here
+\`\`\`
+
+### Bad Example
+\`\`\`language
+// Avoid this pattern
+code example here
+\`\`\`
+```
+
+### 4. Validation and Verification (Optional but Recommended)
+
+- Build commands to verify code
+- Linting and formatting tools
+- Testing requirements
+- Verification steps
+
+## Content Guidelines
+
+### Writing Style
+
+- Use clear, concise language
+- Write in imperative mood ("Use", "Implement", "Avoid")
+- Be specific and actionable
+- Avoid ambiguous terms like "should", "might", "possibly"
+- Use bullet points and lists for readability
+- Keep sections focused and scannable
+
+### Best Practices
+
+- **Be Specific**: Provide concrete examples rather than abstract concepts
+- **Show Why**: Explain the reasoning behind recommendations when it adds value
+- **Use Tables**: For comparing options, listing rules, or showing patterns
+- **Include Examples**: Real code snippets are more effective than descriptions
+- **Stay Current**: Reference current versions and best practices
+- **Link Resources**: Include official documentation and authoritative sources
+
+### Common Patterns to Include
+
+1. **Naming Conventions**: How to name variables, functions, classes, files
+2. **Code Organization**: File structure, module organization, import order
+3. **Error Handling**: Preferred error handling patterns
+4. **Dependencies**: How to manage and document dependencies
+5. **Comments and Documentation**: When and how to document code
+6. **Version Information**: Target language/framework versions
+
+## Patterns to Follow
+
+### Bullet Points and Lists
+
+```markdown
+## Security Best Practices
+
+- Always validate user input before processing
+- Use parameterized queries to prevent SQL injection
+- Store secrets in environment variables, never in code
+- Implement proper authentication and authorization
+- Enable HTTPS for all production endpoints
+```
+
+### Tables for Structured Information
+
+```markdown
+## Common Issues
+
+| Issue            | Solution            | Example                       |
+| ---------------- | ------------------- | ----------------------------- |
+| Magic numbers    | Use named constants | `const MAX_RETRIES = 3`       |
+| Deep nesting     | Extract functions   | Refactor nested if statements |
+| Hardcoded values | Use configuration   | Store API URLs in config      |
+```
+
+### Code Comparison
+
+```markdown
+### Good Example - Using TypeScript interfaces
+\`\`\`typescript
+interface User {
+  id: string;
+  name: string;
+  email: string;
+}
+
+function getUser(id: string): User {
+  // Implementation
+}
+\`\`\`
+
+### Bad Example - Using any type
+\`\`\`typescript
+function getUser(id: any): any {
+  // Loses type safety
+}
+\`\`\`
+```
+
+### Conditional Guidance
+
+```markdown
+## Framework Selection
+
+- **For small projects**: Use Minimal API approach
+- **For large projects**: Use controller-based architecture with clear separation
+- **For microservices**: Consider domain-driven design patterns
+```
+
+## Patterns to Avoid
+
+- **Overly verbose explanations**: Keep it concise and scannable
+- **Outdated information**: Always reference current versions and practices
+- **Ambiguous guidelines**: Be specific about what to do or avoid
+- **Missing examples**: Abstract rules without concrete code examples
+- **Contradictory advice**: Ensure consistency throughout the file
+- **Copy-paste from documentation**: Add value by distilling and contextualizing
+
+## Testing Your Instructions
+
+Before finalizing instruction files:
+
+1. **Test with Copilot**: Try the instructions with actual prompts in VS Code
+2. **Verify Examples**: Ensure code examples are correct and run without errors
+3. **Check Glob Patterns**: Confirm `applyTo` patterns match intended files
+
+## Example Structure
+
+Here's a minimal example structure for a new instruction file:
+
+```markdown
+---
+description: 'Brief description of purpose'
+applyTo: '**/*.ext'
+---
+
+# Technology Name Development
+
+Brief introduction and context.
+
+## General Instructions

+
+# Makefile Development Instructions
+
+Instructions for writing clean, maintainable, and portable GNU Make Makefiles. These instructions are based on the [GNU Make manual](https://www.gnu.org/software/make/manual/).
+
+## General Principles
+
+- Write clear and maintainable makefiles that follow GNU Make conventions
+- Use descriptive target names that clearly indicate their purpose
+- Keep the default goal (first target) as the most common build operation
+- Prioritize readability over brevity when writing rules and recipes
+- Add comments to explain complex rules, variables, or non-obvious behavior
+
+## Naming Conventions
+
+- Name your makefile `Makefile` (recommended for visibility) or `makefile`
+- Use `GNUmakefile` only for GNU Make-specific features incompatible with other make implementations
+- Use standard variable names: `objects`, `OBJECTS`, `objs`, `OBJS`, `obj`, or `OBJ` for object file lists
+- Use uppercase for built-in variable names (e.g., `CC`, `CFLAGS`, `LDFLAGS`)
+- Use descriptive target names that reflect their action (e.g., `clean`, `install`, `test`)
+
+## File Structure
+
+- Place the default goal (primary build target) as the first rule in the makefile
+- Group related targets together logically
+- Define variables at the top of the makefile before rules
+- Use `.PHONY` to declare targets that don't represent files
+- Structure makefiles with: variables, then rules, then phony targets
+
+```makefile
+# Variables
+CC = gcc
+CFLAGS = -Wall -g
+objects = main.o utils.o
+
+# Default goal
+all: program
+
+# Rules
+program: $(objects)
+	$(CC) -o program $(objects)
+
+%.o: %.c
+	$(CC) $(CFLAGS) -c $< -o $@
+
+# Phony targets
+.PHONY: clean all
+clean:
+	rm -f program $(objects)
+```
+
+## Variables and Substitution
+
+- Use variables to avoid duplication and improve maintainability
+- Define variables with `:=` (simple expansion) for immediate evaluation, `=` for recursive expansion
+- Use `?=` to set default values that can be overridden
+- Use `+=` to append to existing variables
+- Reference variables with `$(VARIABLE)` not `$VARIABLE` (unless single character)
+- Use automatic variables (`$@`, `$<`, `$^`, `$?`, `$*`) in recipes to make rules more generic
+
+```makefile
+# Simple expansion (evaluates immediately)
+CC := gcc
+
+# Recursive expansion (evaluates when used)
+CFLAGS = -Wall $(EXTRA_FLAGS)
+
+# Conditional assignment
+PREFIX ?= /usr/local
+
+# Append to variable
+CFLAGS += -g
+```
+
+## Rules and Prerequisites
+
+- Separate targets, prerequisites, and recipes clearly
+- Use implicit rules for standard compilations (e.g., `.c` to `.o`)
+- List prerequisites in logical order (normal prerequisites before order-only)
+- Use order-only prerequisites (after `|`) for directories and dependencies that shouldn't trigger rebuilds
+- Include all actual dependencies to ensure correct rebuilds
+- Avoid circular dependencies between targets
+- Remember that order-only prerequisites are omitted from automatic variables like `$^`, so reference them explicitly if needed
+
+The example below shows a pattern rule that compiles objects into an `obj/` directory. The directory itself is listed as an order-only prerequisite so it is created before compiling but does not force recompilation when its timestamp changes.
+
+```makefile
+# Normal prerequisites
+program: main.o utils.o
+	$(CC) -o $@ $^
+
+# Order-only prerequisites (directory creation)
+obj/%.o: %.c | obj
+	$(CC) $(CFLAGS) -c $< -o $@
+
+obj:
+	mkdir -p obj
+```
+
+## Recipes and Commands
+
+- Start every recipe line with a **tab character** (not spaces) unless `.RECIPEPREFIX` is changed
+- Use `@` prefix to suppress command echoing when appropriate
+- Use `-` prefix to ignore errors for specific commands (use sparingly)
+- Combine related commands with `&&` or `;` on the same line when they must execute together
+- Keep recipes readable; break long commands across multiple lines with backslash continuation
+- Use shell conditionals and loops within recipes when needed
+
+```makefile
+# Silent command
+clean:
+	@echo "Cleaning up..."
+	@rm -f $(objects)
+
+# Ignore errors
+.PHONY: clean-all
+clean-all:
+	-rm -rf build/
+	-rm -rf dist/
+
+# Multi-line recipe with proper continuation
+install: program
+	install -d $(PREFIX)/bin && \
+		install -m 755 program $(PREFIX)/bin
+```
+
+## Phony Targets
+
+- Always declare phony targets with `.PHONY` to avoid conflicts with files of the same name
+- Use phony targets for actions like `clean`, `install`, `test`, `all`
+- Place phony target declarations near their rule definitions or at the end of the makefile
+
+```makefile
+.PHONY: all clean test install
+
+all: program
+
+clean:
+	rm -f program $(objects)
+
+test: program
+	./run-tests.sh
+
+install: program
+	install -m 755 program $(PREFIX)/bin
+```
+
+## Pattern Rules and Implicit Rules
+
+- Use pattern rules (`%.o: %.c`) for generic transformations
+- Leverage built-in implicit rules when appropriate (GNU Make knows how to compile `.c` to `.o`)
+- Override implicit rule variables (like `CC`, `CFLAGS`) rather than rewriting the rules
+- Define custom pattern rules only when built-in rules are insufficient
+
+```makefile
+# Use built-in implicit rules by setting variables
+CC = gcc
+CFLAGS = -Wall -O2
+
+# Custom pattern rule for special cases
+%.pdf: %.md
+	pandoc $< -o $@
+```
+
+## Splitting Long Lines
+
+- Use backslash-newline (`\`) to split long lines for readability
+- Be aware that backslash-newline is converted to a single space in non-recipe contexts
+- In recipes, backslash-newline preserves the line continuation for the shell
+- Avoid trailing whitespace after backslashes
+
+### Splitting Without Adding Whitespace
+
+If you need to split a line without adding whitespace, you can use a special technique: insert `$ ` (dollar-space) followed by a backslash-newline. The `$ ` refers to a variable with a single-space name, which doesn't exist and expands to nothing, effectively joining the lines without inserting a space.
+
+```makefile
+# Concatenate strings without adding whitespace
+# The following creates the value "oneword"
+var := one$ \
+       word
+
+# This is equivalent to:
+# var := oneword
+```
+
+```makefile
+# Variable definition split across lines
+sources = main.c \
+          utils.c \
+          parser.c \
+          handler.c
+
+# Recipe with long command
+build: $(objects)
+	$(CC) -o program $(objects) \
+	      $(LDFLAGS) \
+	      -lm -lpthread
+```
+
+## Including Other Makefiles
+
+- Use `include` directive to share common definitions across makefiles
+- Use `-include` (or `sinclude`) to include optional makefiles without errors
+- Place `include` directives after variable definitions that may affect included files
+- Use `include` for shared variables, pattern rules, or common targets
+
+```makefile
+# Include common settings
+include config.mk
+
+# Include optional local configuration
+-include local.mk
+```
+
+## Conditional Directives
+
+- Use conditional directives (`ifeq`, `ifneq`, `ifdef`, `ifndef`) for platform or configuration-specific rules
+- Place conditionals at the makefile level, not within recipes (use shell conditionals in recipes)
+- Keep conditionals simple and well-documented
+
+```makefile
+# Platform-specific settings
+ifeq ($(OS),Windows_NT)
+    EXE_EXT = .exe
+else
+    EXE_EXT =
+endif
+
+program: main.o
+	$(CC) -o program$(EXE_EXT) main.o
+```
+
+## Automatic Prerequisites
+
+- Generate header dependencies automatically rather than maintaining them manually
+- Use compiler flags like `-MMD` and `-MP` to generate `.d` files with dependencies
+- Include generated dependency files with `-include $(deps)` to avoid errors if they don't exist
+
+```makefile
+objects = main.o utils.o
+deps = $(objects:.o=.d)
+
+# Include dependency files
+-include $(deps)
+
+# Compile with automatic dependency generation
+%.o: %.c
+	$(CC) $(CFLAGS) -MMD -MP -c $< -o $@
+```
+
+## Error Handling and Debugging
+
+- Use `$(error text)` or `$(warning text)` functions for build-time diagnostics
+- Test makefiles with `make -n` (dry run) to see commands without executing
+- Use `make -p` to print the database of rules and variables for debugging
+- Validate required variables and tools at the beginning of the makefile
+
+```makefile
+# Check for required tools
+ifeq ($(shell which gcc),)
+    $(error "gcc is not installed or not in PATH")
+endif
+
+# Validate required variables
+ifndef VERSION
+    $(error VERSION is not defined)
+endif
+```
+
+## Clean Targets
+
+- Always provide a `clean` target to remove generated files
+- Declare `clean` as phony to avoid conflicts with a file named "clean"
+- Use `-` prefix with `rm` commands to ignore errors if files don't exist
+- Consider separate `clean` (removes objects) and `distclean` (removes all generated files) targets
+
+```makefile
+.PHONY: clean distclean
+
+clean:
+	-rm -f $(objects)
+	-rm -f $(deps)
+
+distclean: clean
+	-rm -f program config.mk
+```
+
+## Portability Considerations
+
+- Avoid GNU Make-specific features if portability to other make implementations is required
+- Use standard shell commands (prefer POSIX shell constructs)
+- Test with `make -B` to force rebuild all targets
+- Document any platform-specific requirements or GNU Make extensions used
+
+## Performance Optimization
+
+- Use `:=` for variables that don't need recursive expansion (faster)
+- Avoid unnecessary use of `$(shell ...)` which creates subprocesses
+- Order prerequisites efficiently (most frequently changing files last)
+- Use parallel builds (`make -j`) safely by ensuring targets don't conflict
+
+## Documentation and Comments
+
+- Add a header comment explaining the makefile's purpose
+- Document non-obvious variable settings and their effects
+- Include usage examples or targets in comments
+- Add inline comments for complex rules or platform-specific workarounds
+
+```makefile
+# Makefile for building the example application
+#
+# Usage:
+#   make          - Build the program
+#   make clean    - Remove generated files
+#   make install  - Install to $(PREFIX)
+#
+# Variables:
+#   CC       - C compiler (default: gcc)
+#   PREFIX   - Installation prefix (default: /usr/local)
+
+# Compiler and flags
+CC ?= gcc
+CFLAGS = -Wall -Wextra -O2
+
+# Installation directory
+PREFIX ?= /usr/local
+```
+
+## Special Targets
+
+- Use `.PHONY` for non-file targets
+- Use `.PRECIOUS` to preserve intermediate files
+- Use `.INTERMEDIATE` to mark files as intermediate (automatically deleted)
+- Use `.SECONDARY` to prevent deletion of intermediate files
+- Use `.DELETE_ON_ERROR` to remove targets if recipe fails
+- Use `.SILENT` to suppress echoing for all recipes (use sparingly)
+
+```makefile
+# Don't delete intermediate files

+
+## Anti-Patterns to Avoid
+
+- Don't start recipe lines with spaces instead of tabs
+- Avoid hardcoding file lists when they can be generated with wildcards or functions
+- Don't use `$(shell ls ...)` to get file lists (use `$(wildcard ...)` instead)
+- Avoid complex shell scripts in recipes (move to separate script files)
+- Don't forget to declare phony targets as `.PHONY`
+- Avoid circular dependencies between targets
+- Don't use recursive make (`$(MAKE) -C subdir`) unless absolutely necessary

+
+## Markdown Content Rules
+
+The following markdown content rules are enforced in the validators:
+
+1. **Headings**: Use appropriate heading levels (H2, H3, etc.) to structure your content. Do not use an H1 heading, as this will be generated based on the title.
+2. **Lists**: Use bullet points or numbered lists for lists. Ensure proper indentation and spacing.
+3. **Code Blocks**: Use fenced code blocks for code snippets. Specify the language for syntax highlighting.
+4. **Links**: Use proper markdown syntax for links. Ensure that links are valid and accessible.
+5. **Images**: Use proper markdown syntax for images. Include alt text for accessibility.
+6. **Tables**: Use markdown tables for tabular data. Ensure proper formatting and alignment.
+7. **Line Length**: Limit line length to 400 characters for readability.
+8. **Whitespace**: Use appropriate whitespace to separate sections and improve readability.
+9. **Front Matter**: Include YAML front matter at the beginning of the file with required metadata fields.
+
+## Formatting and Structure
+
+Follow these guidelines for formatting and structuring your markdown content:
+
+- **Headings**: Use `##` for H2 and `###` for H3. Ensure that headings are used in a hierarchical manner. Recommend restructuring if content includes H4, and more strongly recommend for H5.
+- **Lists**: Use `-` for bullet points and `1.` for numbered lists. Indent nested lists with two spaces.
+- **Code Blocks**: Use triple backticks (`) to create fenced code blocks. Specify the language after the opening backticks for syntax highlighting (e.g., `csharp).
+- **Links**: Use `[link text](https://example.com)` for links. Ensure that the link text is descriptive and the URL is valid.
+- **Images**: Use `![alt text](image URL)` for images. Include a brief description of the image in the alt text.
+- **Tables**: Use `|` to create tables. Ensure that columns are properly aligned and headers are included.
+- **Line Length**: Break lines at 80 characters to improve readability. Use soft line breaks for long paragraphs.
+- **Whitespace**: Use blank lines to separate sections and improve readability. Avoid excessive whitespace.
+
+## Validation Requirements
+
+Ensure compliance with the following validation requirements:
+
+- **Front Matter**: Include the following fields in the YAML front matter:
+
+  - `post_title`: The title of the post.
+  - `categories`: The categories for the post. These categories must be from the list in /categories.txt.
+  - `tags`: The tags for the post.
+  - `summary`: A brief summary of the post. Recommend a summary based on the content when possible.
+  - `post_date`: The publication date of the post.
+
+- **Content Rules**: Ensure that the content follows the markdown content rules specified above.
+- **Formatting**: Ensure that the content is properly formatted and structured according to the guidelines.
+- **Validation**: Run the validation tools to check for compliance with the rules and guidelines.

+
+# Code Generation Guidelines
+
+## Coding standards
+- Use JavaScript with ES2022 features and Node.js (20+) ESM modules
+- Use Node.js built-in modules and avoid external dependencies where possible
+- Ask the user if you require any additional dependencies before adding them
+- Always use async/await for asynchronous code, and use 'node:util' promisify function to avoid callbacks
+- Keep the code simple and maintainable
+- Use descriptive variable and function names
+- Do not add comments unless absolutely necessary, the code should be self-explanatory
+- Never use `null`, always use `undefined` for optional values
+- Prefer functions over classes
+
+## Testing
+- Use Vitest for testing
+- Write tests for all new features and bug fixes
+- Ensure tests cover edge cases and error handling
+- NEVER change the original code to make it easier to test, instead, write tests that cover the original code as it is
+
+## Documentation
+- When adding new features or making significant changes, update the README.md file where necessary
+
+## User interactions
+- Ask questions if you are unsure about the implementation details, design choices, or need clarification on the requirements
+- Always answer in the same language as the question, but use english for the generated content like code, comments or docs

+# Object Calisthenics Rules
+
+> ⚠️ **Warning:** This file contains the 9 original Object Calisthenics rules. No additional rules must be added, and none of these rules should be replaced or removed.
+> Examples may be added later if needed.
+
+## Objective
+This rule enforces the principles of Object Calisthenics to ensure clean, maintainable, and robust code in the backend, **primarily for business domain code**.
+
+## Scope and Application
+- **Primary focus**: Business domain classes (aggregates, entities, value objects, domain services)
+- **Secondary focus**: Application layer services and use case handlers
+- **Exemptions**:
+  - DTOs (Data Transfer Objects)
+  - API models/contracts
+  - Configuration classes
+  - Simple data containers without business logic
+  - Infrastructure code where flexibility is needed
+
+## Key Principles
+
+
+1. **One Level of Indentation per Method**:
+   - Ensure methods are simple and do not exceed one level of indentation.
+
+   ```csharp
+   // Bad Example - this method has multiple levels of indentation
+   public void SendNewsletter() {
+         foreach (var user in users) {
+            if (user.IsActive) {
+               // Do something
+               mailer.Send(user.Email);
+            }
+         }
+   }
+   // Good Example - Extracted method to reduce indentation
+   public void SendNewsletter() {
+       foreach (var user in users) {
+           SendEmail(user);
+       }
+   }
+   private void SendEmail(User user) {
+       if (user.IsActive) {
+           mailer.Send(user.Email);
+       }
+   }
+
+   // Good Example - Filtering users before sending emails
+   public void SendNewsletter() {
+       var activeUsers = users.Where(user => user.IsActive);
+
+       foreach (var user in activeUsers) {
+           mailer.Send(user.Email);
+       }
+   }
+   ```
+2. **Don't Use the ELSE Keyword**:
+
+   - Avoid using the `else` keyword to reduce complexity and improve readability.
+   - Use early returns to handle conditions instead.
+   - Use Fail Fast principle
+   - Use Guard Clauses to validate inputs and conditions at the beginning of methods.
+
+   ```csharp
+   // Bad Example - Using else
+   public void ProcessOrder(Order order) {
+       if (order.IsValid) {
+           // Process order
+       } else {
+           // Handle invalid order
+       }
+   }
+   // Good Example - Avoiding else
+   public void ProcessOrder(Order order) {
+       if (!order.IsValid) return;
+       // Process order
+   }
+   ```
+
+   Sample Fail fast principle:
+   ```csharp
+   public void ProcessOrder(Order order) {
+       if (order == null) throw new ArgumentNullException(nameof(order));
+       if (!order.IsValid) throw new InvalidOperationException("Invalid order");
+       // Process order
+   }
+   ```
+
+3. **Wrapping All Primitives and Strings**:
+   - Avoid using primitive types directly in your code.
+   - Wrap them in classes to provide meaningful context and behavior.
+
+   ```csharp
+   // Bad Example - Using primitive types directly
+   public class User {
+       public string Name { get; set; }
+       public int Age { get; set; }
+   }
+   // Good Example - Wrapping primitives
+   public class User {
+       private string name;
+       private Age age;
+       public User(string name, Age age) {
+           this.name = name;
+           this.age = age;
+       }
+   }
+   public class Age {
+       private int value;
+       public Age(int value) {
+           if (value < 0) throw new ArgumentOutOfRangeException(nameof(value), "Age cannot be negative");
+           this.value = value;
+       }
+   }
+   ```
+
+4. **First Class Collections**:
+   - Use collections to encapsulate data and behavior, rather than exposing raw data structures.
+First Class Collections: a class that contains an array as an attribute should not contain any other attributes
+
+```csharp
+   // Bad Example - Exposing raw collection
+   public class Group {
+      public int Id { get; private set; }
+      public string Name { get; private set; }
+      public List<User> Users { get; private set; }
+
+      public int GetNumberOfUsersIsActive() {
+         return Users
+            .Where(user => user.IsActive)
+            .Count();
+      }
+   }
+
+   // Good Example - Encapsulating collection behavior
+   public class Group {
+      public int Id { get; private set; }
+      public string Name { get; private set; }
+
+      public GroupUserCollection userCollection { get; private set; } // The list of users is encapsulated in a class
+
+      public int GetNumberOfUsersIsActive() {
+         return userCollection
+            .GetActiveUsers()
+            .Count();
+      }
+   }
+   ```
+
+5. **One Dot per Line**:
+   - Avoid violating Law of Demeter by only having a single dot per line.
+
+   ```csharp
+   // Bad Example - Multiple dots in a single line
+   public void ProcessOrder(Order order) {
+       var userEmail = order.User.GetEmail().ToUpper().Trim();
+       // Do something with userEmail
+   }
+   // Good Example - One dot per line
+   public class User {
+     public NormalizedEmail GetEmail() {
+       return NormalizedEmail.Create(/*...*/);
+     }
+   }
+   public class Order {
+     /*...*/
+     public NormalizedEmail ConfirmationEmail() {
+       return User.GetEmail();
+     }
+   }
+   public void ProcessOrder(Order order) {
+       var confirmationEmail = order.ConfirmationEmail();
+       // Do something with confirmationEmail
+   }
+   ```
+
+6. **Don't abbreviate**:
+   - Use meaningful names for classes, methods, and variables.
+   - Avoid abbreviations that can lead to confusion.
+
+   ```csharp
+   // Bad Example - Abbreviated names
+   public class U {
+       public string N { get; set; }
+   }
+   // Good Example - Meaningful names
+   public class User {
+       public string Name { get; set; }
+   }
+   ```
+
+7. **Keep entities small (Class, method, namespace or package)**:
+   - Limit the size of classes and methods to improve code readability and maintainability.
+   - Each class should have a single responsibility and be as small as possible.
+
+   Constraints:
+   - Maximum 10 methods per class
+   - Maximum 50 lines per class
+   - Maximum 10 classes per package or namespace
+
+   ```csharp
+   // Bad Example - Large class with multiple responsibilities
+   public class UserManager {
+       public void CreateUser(string name) { /*...*/ }
+       public void DeleteUser(int id) { /*...*/ }
+       public void SendEmail(string email) { /*...*/ }
+   }
+
+   // Good Example - Small classes with single responsibility
+   public class UserCreator {
+       public void CreateUser(string name) { /*...*/ }
+   }
+   public class UserDeleter {
+       public void DeleteUser(int id) { /*...*/ }
+   }
+
+   public class UserUpdater {
+       public void UpdateUser(int id, string name) { /*...*/ }
+   }
+   ```
+
+
+8. **No Classes with More Than Two Instance Variables**:
+   - Encourage classes to have a single responsibility by limiting the number of instance variables.
+   - Limit the number of instance variables to two to maintain simplicity.
+   - Do not count ILogger or any other logger as instance variable.
+
+   ```csharp
+   // Bad Example - Class with multiple instance variables
+   public class UserCreateCommandHandler {
+      // Bad: Too many instance variables
+      private readonly IUserRepository userRepository;
+      private readonly IEmailService emailService;
+      private readonly ILogger logger;
+      private readonly ISmsService smsService;
+
+      public UserCreateCommandHandler(IUserRepository userRepository, IEmailService emailService, ILogger logger, ISmsService smsService) {
+         this.userRepository = userRepository;
+         this.emailService = emailService;
+         this.logger = logger;
+         this.smsService = smsService;
+      }
+   }
+
+   // Good: Class with two instance variables
+   public class UserCreateCommandHandler {
+      private readonly IUserRepository userRepository;
+      private readonly INotificationService notificationService;
+      private readonly ILogger logger; // This is not counted as instance variable
+
+      public UserCreateCommandHandler(IUserRepository userRepository, INotificationService notificationService, ILogger logger) {
+         this.userRepository = userRepository;
+         this.notificationService = notificationService;
+         this.logger = logger;
+      }
+   }
+   ```
+
+9. **No Getters/Setters in Domain Classes**:
+   - Avoid exposing setters for properties in domain classes.
+   - Use private constructors and static factory methods for object creation.
+   - **Note**: This rule applies primarily to domain classes, not DTOs or data transfer objects.
+
+   ```csharp
+   // Bad Example - Domain class with public setters
+   public class User {  // Domain class
+       public string Name { get; set; } // Avoid this in domain classes
+   }
+
+   // Good Example - Domain class with encapsulation
+   public class User {  // Domain class
+       private string name;
+       private User(string name) { this.name = name; }
+       public static User Create(string name) => new User(name);
+   }
+
+   // Acceptable Example - DTO with public setters
+   public class UserDto {  // DTO - exemption applies
+       public string Name { get; set; } // Acceptable for DTOs
+   }
+   ```
+
+## Implementation Guidelines
+- **Domain Classes**:
+  - Use private constructors and static factory methods for creating instances.
+  - Avoid exposing setters for properties.
+  - Apply all 9 rules strictly for business domain code.
+
+- **Application Layer**:
+  - Apply these rules to use case handlers and application services.
+  - Focus on maintaining single responsibility and clean abstractions.
+
+- **DTOs and Data Objects**:
+  - Rules 3 (wrapping primitives), 8 (two instance variables), and 9 (no getters/setters) may be relaxed for DTOs.
+  - Public properties with getters/setters are acceptable for data transfer objects.
+
+- **Testing**:
+  - Ensure tests validate the behavior of objects rather than their state.
+  - Test classes may have relaxed rules for readability and maintainability.
+
+- **Code Reviews**:
+  - Enforce these rules during code reviews for domain and application code.
+  - Be pragmatic about infrastructure and DTO code.

+# React Controls & Platform Libraries
+
+When you use React and platform libraries, you're using the same infrastructure used by the Power Apps platform. This means you no longer have to package React and Fluent libraries individually for each control. All controls share a common library instance and version to provide a seamless and consistent experience.
+
+## Benefits
+
+By reusing the existing platform React and Fluent libraries, you can expect:
+
+- **Reduced control bundle size**
+- **Optimized solution packaging**
+- **Faster runtime transfer, scripting, and control rendering**
+- **Design and theme alignment with the Power Apps Fluent design system**
+
+> **Note**: With GA release, all existing virtual controls will continue to function. However, they should be rebuilt and deployed using the latest CLI version (>=1.37) to facilitate future platform React version upgrades.
+
+## Prerequisites
+
+As with any component, you must install [Visual Studio Code](https://code.visualstudio.com/Download) and the [Microsoft Power Platform CLI](https://learn.microsoft.com/en-us/power-apps/developer/data-platform/powerapps-cli#install-microsoft-power-platform-cli).
+
+> **Note**: If you have already installed Power Platform CLI for Windows, make sure you are running the latest version by using the `pac install latest` command. The Power Platform Tools for Visual Studio Code should update automatically.
+
+## Create a React Component
+
+> **Note**: These instructions expect that you have created code components before. If you have not, see [Create your first component](https://learn.microsoft.com/en-us/power-apps/developer/component-framework/implementing-controls-using-typescript).
+
+There's a new `--framework` (`-fw`) parameter for the `pac pcf init` command. Set the value of this parameter to `react`.
+
+### Command Parameters
+
+| Parameter | Value |
+|-----------|-------|
+| --name | ReactSample |
+| --namespace | SampleNamespace |
+| --template | field |
+| --framework | react |
+| --run-npm-install | true (default) |
+
+### PowerShell Command
+
+The following PowerShell command uses the parameter shortcuts and creates a React component project and runs `npm-install`:
+
+```powershell
+pac pcf init -n ReactSample -ns SampleNamespace -t field -fw react -npm
+```
+
+You can now build and view the control in the test harness as usual using `npm start`.
+
+After you build the control, you can package it inside solutions and use it for model-driven apps (including custom pages) and canvas apps like standard code components.
+
+## Differences from Standard Components
+
+### ControlManifest.Input.xml
+
+The [control element](https://learn.microsoft.com/en-us/power-apps/developer/component-framework/manifest-schema-reference/control) `control-type` attribute is set to `virtual` rather than `standard`.
+
+> **Note**: Changing this value does not convert a component from one type to another.
+
+Within the [resources element](https://learn.microsoft.com/en-us/power-apps/developer/component-framework/manifest-schema-reference/resources), find two new [platform-library element](https://learn.microsoft.com/en-us/power-apps/developer/component-framework/manifest-schema-reference/platform-library) child elements:
+
+```xml
+<resources>
+  <code path="index.ts" order="1" />
+  <platform-library name="React" version="16.14.0" />
+  <platform-library name="Fluent" version="9.46.2" />
+</resources>
+```
+
+> **Note**: For more information about valid platform library versions, see Supported platform libraries list.
+
+**Recommendation**: We recommend using platform libraries for Fluent 8 and 9. If you don't use Fluent, you should remove the `platform-library` element where the `name` attribute value is `Fluent`.
+
+### Index.ts
+
+The [ReactControl.init](https://learn.microsoft.com/en-us/power-apps/developer/component-framework/reference/react-control/init) method for control initialization doesn't have `div` parameters because React controls don't render the DOM directly. Instead [ReactControl.updateView](https://learn.microsoft.com/en-us/power-apps/developer/component-framework/reference/react-control/updateview) returns a ReactElement that has the details of the actual control in React format.
+
+### bundle.js
+
+React and Fluent libraries aren't included in the package because they're shared, therefore the size of bundle.js is smaller.
+
+## Sample Controls
+
+The following controls are included in the samples. They function the same as their standard versions but offer better performance since they are virtual controls.
+
+| Sample | Description | Link |
+|--------|-------------|------|
+| ChoicesPickerReact | The standard ChoicesPickerControl converted to be a React Control | ChoicesPickerReact Sample |
+| FacepileReact | The ReactStandardControl converted to be a React Control | FacepileReact |
+
+## Supported Platform Libraries List
+
+Platform libraries are made available both at the build and runtime to the controls that are using platform libraries capability. Currently, the following versions are provided by the platform and are the highest currently supported versions.
+
+| Library | Package | Build Version | Runtime Version |
+|---------|---------|---------------|-----------------|
+| React | react | 16.14.0 | 17.0.2 (Model), 16.14.0 (Canvas) |
+| Fluent | @fluentui/react | 8.29.0 | 8.29.0 |
+| Fluent | @fluentui/react | 8.121.1 | 8.121.1 |
+| Fluent | @fluentui/react-components | >=9.4.0 <=9.46.2 | 9.68.0 |
+
+> **Note**: The application might load a higher compatible version of a platform library at runtime, but the version might not be the latest version available. Fluent 8 and Fluent 9 are each supported but can not both be specified in the same manifest.
+
+## FAQ
+
+### Q: Can I convert an existing standard control to a React control using platform libraries?
+
+A: No. You must create a new control using the new template and then update the manifest and index.ts methods. For reference, compare the standard and react samples described above.
+
+### Q: Can I use React controls & platform libraries with Power Pages?
+
+A: No. React controls & platform libraries are currently only supported for canvas and model-driven apps. In Power Pages, React controls don't update based on changes in other fields.

+# Performance Optimization Best Practices
+
+## Introduction
+
+Performance isn't just a buzzword—it's the difference between a product people love and one they abandon. I've seen firsthand how a slow app can frustrate users, rack up cloud bills, and even lose customers. This guide is a living collection of the most effective, real-world performance practices I've used and reviewed, covering frontend, backend, and database layers, as well as advanced topics. Use it as a reference, a checklist, and a source of inspiration for building fast, efficient, and scalable software.
+
+---
+
+## General Principles
+
+- **Measure First, Optimize Second:** Always profile and measure before optimizing. Use benchmarks, profilers, and monitoring tools to identify real bottlenecks. Guessing is the enemy of performance.
+  - *Pro Tip:* Use tools like Chrome DevTools, Lighthouse, New Relic, Datadog, Py-Spy, or your language's built-in profilers.
+- **Optimize for the Common Case:** Focus on optimizing code paths that are most frequently executed. Don't waste time on rare edge cases unless they're critical.
+- **Avoid Premature Optimization:** Write clear, maintainable code first; optimize only when necessary. Premature optimization can make code harder to read and maintain.
+- **Minimize Resource Usage:** Use memory, CPU, network, and disk resources efficiently. Always ask: "Can this be done with less?"
+- **Prefer Simplicity:** Simple algorithms and data structures are often faster and easier to optimize. Don't over-engineer.
+- **Document Performance Assumptions:** Clearly comment on any code that is performance-critical or has non-obvious optimizations. Future maintainers (including you) will thank you.
+- **Understand the Platform:** Know the performance characteristics of your language, framework, and runtime. What's fast in Python may be slow in JavaScript, and vice versa.
+- **Automate Performance Testing:** Integrate performance tests and benchmarks into your CI/CD pipeline. Catch regressions early.
+- **Set Performance Budgets:** Define acceptable limits for load time, memory usage, API latency, etc. Enforce them with automated checks.
+
+---
+
+## Frontend Performance
+
+### Rendering and DOM
+- **Minimize DOM Manipulations:** Batch updates where possible. Frequent DOM changes are expensive.
+  - *Anti-pattern:* Updating the DOM in a loop. Instead, build a document fragment and append it once.
+- **Virtual DOM Frameworks:** Use React, Vue, or similar efficiently—avoid unnecessary re-renders.
+  - *React Example:* Use `React.memo`, `useMemo`, and `useCallback` to prevent unnecessary renders.
+- **Keys in Lists:** Always use stable keys in lists to help virtual DOM diffing. Avoid using array indices as keys unless the list is static.
+- **Avoid Inline Styles:** Inline styles can trigger layout thrashing. Prefer CSS classes.
+- **CSS Animations:** Use CSS transitions/animations over JavaScript for smoother, GPU-accelerated effects.
+- **Defer Non-Critical Rendering:** Use `requestIdleCallback` or similar to defer work until the browser is idle.
+
+### Asset Optimization
+- **Image Compression:** Use tools like ImageOptim, Squoosh, or TinyPNG. Prefer modern formats (WebP, AVIF) for web delivery.
+- **SVGs for Icons:** SVGs scale well and are often smaller than PNGs for simple graphics.
+- **Minification and Bundling:** Use Webpack, Rollup, or esbuild to bundle and minify JS/CSS. Enable tree-shaking to remove dead code.
+- **Cache Headers:** Set long-lived cache headers for static assets. Use cache busting for updates.
+- **Lazy Loading:** Use `loading="lazy"` for images, and dynamic imports for JS modules/components.
+- **Font Optimization:** Use only the character sets you need. Subset fonts and use `font-display: swap`.
+
+### Network Optimization
+- **Reduce HTTP Requests:** Combine files, use image sprites, and inline critical CSS.
+- **HTTP/2 and HTTP/3:** Enable these protocols for multiplexing and lower latency.
+- **Client-Side Caching:** Use Service Workers, IndexedDB, and localStorage for offline and repeat visits.
+- **CDNs:** Serve static assets from a CDN close to your users. Use multiple CDNs for redundancy.
+- **Defer/Async Scripts:** Use `defer` or `async` for non-critical JS to avoid blocking rendering.
+- **Preload and Prefetch:** Use `<link rel="preload">` and `<link rel="prefetch">` for critical resources.
+
+### JavaScript Performance
+- **Avoid Blocking the Main Thread:** Offload heavy computation to Web Workers.
+- **Debounce/Throttle Events:** For scroll, resize, and input events, use debounce/throttle to limit handler frequency.
+- **Memory Leaks:** Clean up event listeners, intervals, and DOM references. Use browser dev tools to check for detached nodes.
+- **Efficient Data Structures:** Use Maps/Sets for lookups, TypedArrays for numeric data.
+- **Avoid Global Variables:** Globals can cause memory leaks and unpredictable performance.
+- **Avoid Deep Object Cloning:** Use shallow copies or libraries like lodash's `cloneDeep` only when necessary.
+
+### Accessibility and Performance
+- **Accessible Components:** Ensure ARIA updates are not excessive. Use semantic HTML for both accessibility and performance.
+- **Screen Reader Performance:** Avoid rapid DOM updates that can overwhelm assistive tech.
+
+### Framework-Specific Tips
+#### React
+- Use `React.memo`, `useMemo`, and `useCallback` to avoid unnecessary renders.
+- Split large components and use code-splitting (`React.lazy`, `Suspense`).
+- Avoid anonymous functions in render; they create new references on every render.
+- Use `ErrorBoundary` to catch and handle errors gracefully.
+- Profile with React DevTools Profiler.
+
+#### Angular
+- Use OnPush change detection for components that don't need frequent updates.
+- Avoid complex expressions in templates; move logic to the component class.
+- Use `trackBy` in `ngFor` for efficient list rendering.
+- Lazy load modules and components with the Angular Router.
+- Profile with Angular DevTools.
+
+#### Vue
+- Use computed properties over methods in templates for caching.
+- Use `v-show` vs `v-if` appropriately (`v-show` is better for toggling visibility frequently).
+- Lazy load components and routes with Vue Router.
+- Profile with Vue Devtools.
+
+### Common Frontend Pitfalls
+- Loading large JS bundles on initial page load.
+- Not compressing images or using outdated formats.
+- Failing to clean up event listeners, causing memory leaks.
+- Overusing third-party libraries for simple tasks.
+- Ignoring mobile performance (test on real devices!).
+
+### Frontend Troubleshooting
+- Use Chrome DevTools' Performance tab to record and analyze slow frames.
+- Use Lighthouse to audit performance and get actionable suggestions.
+- Use WebPageTest for real-world load testing.
+- Monitor Core Web Vitals (LCP, FID, CLS) for user-centric metrics.
+
+---
+
+## Backend Performance
+
+### Algorithm and Data Structure Optimization
+- **Choose the Right Data Structure:** Arrays for sequential access, hash maps for fast lookups, trees for hierarchical data, etc.
+- **Efficient Algorithms:** Use binary search, quicksort, or hash-based algorithms where appropriate.
+- **Avoid O(n^2) or Worse:** Profile nested loops and recursive calls. Refactor to reduce complexity.
+- **Batch Processing:** Process data in batches to reduce overhead (e.g., bulk database inserts).
+- **Streaming:** Use streaming APIs for large data sets to avoid loading everything into memory.
+
+### Concurrency and Parallelism
+- **Asynchronous I/O:** Use async/await, callbacks, or event loops to avoid blocking threads.
+- **Thread/Worker Pools:** Use pools to manage concurrency and avoid resource exhaustion.
+- **Avoid Race Conditions:** Use locks, semaphores, or atomic operations where needed.
+- **Bulk Operations:** Batch network/database calls to reduce round trips.
+- **Backpressure:** Implement backpressure in queues and pipelines to avoid overload.
+
+### Caching
+- **Cache Expensive Computations:** Use in-memory caches (Redis, Memcached) for hot data.
+- **Cache Invalidation:** Use time-based (TTL), event-based, or manual invalidation. Stale cache is worse than no cache.
+- **Distributed Caching:** For multi-server setups, use distributed caches and be aware of consistency issues.
+- **Cache Stampede Protection:** Use locks or request coalescing to prevent thundering herd problems.
+- **Don't Cache Everything:** Some data is too volatile or sensitive to cache.
+
+### API and Network
+- **Minimize Payloads:** Use JSON, compress responses (gzip, Brotli), and avoid sending unnecessary data.
+- **Pagination:** Always paginate large result sets. Use cursors for real-time data.
+- **Rate Limiting:** Protect APIs from abuse and overload.
+- **Connection Pooling:** Reuse connections for databases and external services.
+- **Protocol Choice:** Use HTTP/2, gRPC, or WebSockets for high-throughput, low-latency communication.
+
+### Logging and Monitoring
+- **Minimize Logging in Hot Paths:** Excessive logging can slow down critical code.
+- **Structured Logging:** Use JSON or key-value logs for easier parsing and analysis.
+- **Monitor Everything:** Latency, throughput, error rates, resource usage. Use Prometheus, Grafana, Datadog, or similar.
+- **Alerting:** Set up alerts for performance regressions and resource exhaustion.
+
+### Language/Framework-Specific Tips
+#### Node.js
+- Use asynchronous APIs; avoid blocking the event loop (e.g., never use `fs.readFileSync` in production).
+- Use clustering or worker threads for CPU-bound tasks.
+- Limit concurrent open connections to avoid resource exhaustion.
+- Use streams for large file or network data processing.
+- Profile with `clinic.js`, `node --inspect`, or Chrome DevTools.
+
+#### Python
+- Use built-in data structures (`dict`, `set`, `deque`) for speed.
+- Profile with `cProfile`, `line_profiler`, or `Py-Spy`.
+- Use `multiprocessing` or `asyncio` for parallelism.
+- Avoid GIL bottlenecks in CPU-bound code; use C extensions or subprocesses.
+- Use `lru_cache` for memoization.
+
+#### Java
+- Use efficient collections (`ArrayList`, `HashMap`, etc.).
+- Profile with VisualVM, JProfiler, or YourKit.
+- Use thread pools (`Executors`) for concurrency.
+- Tune JVM options for heap and garbage collection (`-Xmx`, `-Xms`, `-XX:+UseG1GC`).
+- Use `CompletableFuture` for async programming.
+
+#### .NET
+- Use `async/await` for I/O-bound operations.
+- Use `Span<T>` and `Memory<T>` for efficient memory access.
+- Profile with dotTrace, Visual Studio Profiler, or PerfView.
+- Pool objects and connections where appropriate.
+- Use `IAsyncEnumerable<T>` for streaming data.
+
+### Common Backend Pitfalls
+- Synchronous/blocking I/O in web servers.
+- Not using connection pooling for databases.
+- Over-caching or caching sensitive/volatile data.
+- Ignoring error handling in async code.
+- Not monitoring or alerting on performance regressions.
+
+### Backend Troubleshooting
+- Use flame graphs to visualize CPU usage.
+- Use distributed tracing (OpenTelemetry, Jaeger, Zipkin) to track request latency across services.
+- Use heap dumps and memory profilers to find leaks.
+- Log slow queries and API calls for analysis.
+
+---
+
+## Database Performance
+
+### Query Optimization
+- **Indexes:** Use indexes on columns that are frequently queried, filtered, or joined. Monitor index usage and drop unused indexes.
+- **Avoid SELECT *:** Select only the columns you need. Reduces I/O and memory usage.
+- **Parameterized Queries:** Prevent SQL injection and improve plan caching.
+- **Query Plans:** Analyze and optimize query execution plans. Use `EXPLAIN` in SQL databases.
+- **Avoid N+1 Queries:** Use joins or batch queries to avoid repeated queries in loops.
+- **Limit Result Sets:** Use `LIMIT`/`OFFSET` or cursors for large tables.
+
+### Schema Design
+- **Normalization:** Normalize to reduce redundancy, but denormalize for read-heavy workloads if needed.
+- **Data Types:** Use the most efficient data types and set appropriate constraints.
+- **Partitioning:** Partition large tables for scalability and manageability.
+- **Archiving:** Regularly archive or purge old data to keep tables small and fast.
+- **Foreign Keys:** Use them for data integrity, but be aware of performance trade-offs in high-write scenarios.
+
+### Transactions
+- **Short Transactions:** Keep transactions as short as possible to reduce lock contention.
+- **Isolation Levels:** Use the lowest isolation level that meets your consistency needs.
+- **Avoid Long-Running Transactions:** They can block other operations and increase deadlocks.
+
+### Caching and Replication
+- **Read Replicas:** Use for scaling read-heavy workloads. Monitor replication lag.
+- **Cache Query Results:** Use Redis or Memcached for frequently accessed queries.
+- **Write-Through/Write-Behind:** Choose the right strategy for your consistency needs.
+- **Sharding:** Distribute data across multiple servers for scalability.
+
+### NoSQL Databases
+- **Design for Access Patterns:** Model your data for the queries you need.
+- **Avoid Hot Partitions:** Distribute writes/reads evenly.
+- **Unbounded Growth:** Watch for unbounded arrays or documents.
+- **Sharding and Replication:** Use for scalability and availability.
+- **Consistency Models:** Understand eventual vs strong consistency and choose appropriately.
+
+### Common Database Pitfalls
+- Missing or unused indexes.
+- SELECT * in production queries.
+- Not monitoring slow queries.
+- Ignoring replication lag.
+- Not archiving old data.
+
+### Database Troubleshooting
+- Use slow query logs to identify bottlenecks.
+- Use `EXPLAIN` to analyze query plans.
+- Monitor cache hit/miss ratios.
+- Use database-specific monitoring tools (pg_stat_statements, MySQL Performance Schema).
+
+---

+
+---
+
+## Practical Examples
+
+### Example 1: Debouncing User Input in JavaScript
+```javascript
+// BAD: Triggers API call on every keystroke
+input.addEventListener('input', (e) => {
+  fetch(`/search?q=${e.target.value}`);
+});
+
+// GOOD: Debounce API calls
+let timeout;
+input.addEventListener('input', (e) => {
+  clearTimeout(timeout);
+  timeout = setTimeout(() => {
+    fetch(`/search?q=${e.target.value}`);
+  }, 300);
+});
+```
+
+### Example 2: Efficient SQL Query
+```sql
+-- BAD: Selects all columns and does not use an index
+SELECT * FROM users WHERE email = 'user@example.com';
+
+-- GOOD: Selects only needed columns and uses an index
+SELECT id, name FROM users WHERE email = 'user@example.com';
+```
+
+### Example 3: Caching Expensive Computation in Python
+```python
+# BAD: Recomputes result every time
+result = expensive_function(x)
+
+# GOOD: Cache result
+from functools import lru_cache
+
+@lru_cache(maxsize=128)
+def expensive_function(x):
+    ...
+result = expensive_function(x)
+```
+
+### Example 4: Lazy Loading Images in HTML
+```html
+<!-- BAD: Loads all images immediately -->
+<img src="large-image.jpg" />
+
+<!-- GOOD: Lazy loads images -->
+<img src="large-image.jpg" loading="lazy" />
+```
+
+### Example 5: Asynchronous I/O in Node.js
+```javascript
+// BAD: Blocking file read
+const data = fs.readFileSync('file.txt');
+
+// GOOD: Non-blocking file read
+fs.readFile('file.txt', (err, data) => {
+  if (err) throw err;
+  // process data
+});
+```
+
+### Example 6: Profiling a Python Function
+```python
+import cProfile
+import pstats
+
+def slow_function():
+    ...
+
+cProfile.run('slow_function()', 'profile.stats')
+p = pstats.Stats('profile.stats')
+p.sort_stats('cumulative').print_stats(10)
+```
+
+### Example 7: Using Redis for Caching in Node.js
+```javascript
+const redis = require('redis');
+const client = redis.createClient();
+
+function getCachedData(key, fetchFunction) {
+  return new Promise((resolve, reject) => {
+    client.get(key, (err, data) => {
+      if (data) return resolve(JSON.parse(data));
+      fetchFunction().then(result => {
+        client.setex(key, 3600, JSON.stringify(result));
+        resolve(result);
+      });
+    });
+  });
+}
+```

+
+## Test Writing Guidelines
+
+### Code Quality Standards
+- **Locators**: Prioritize user-facing, role-based locators (`getByRole`, `getByLabel`, `getByText`, etc.) for resilience and accessibility. Use `test.step()` to group interactions and improve test readability and reporting.
+- **Assertions**: Use auto-retrying web-first assertions. These assertions start with the `await` keyword (e.g., `await expect(locator).toHaveText()`). Avoid `expect(locator).toBeVisible()` unless specifically testing for visibility changes.
+- **Timeouts**: Rely on Playwright's built-in auto-waiting mechanisms. Avoid hard-coded waits or increased default timeouts.
+- **Clarity**: Use descriptive test and step titles that clearly state the intent. Add comments only to explain complex logic or non-obvious interactions.
+
+
+### Test Structure
+- **Imports**: Start with `import { test, expect } from '@playwright/test';`.
+- **Organization**: Group related tests for a feature under a `test.describe()` block.
+- **Hooks**: Use `beforeEach` for setup actions common to all tests in a `describe` block (e.g., navigating to a page).
+- **Titles**: Follow a clear naming convention, such as `Feature - Specific action or scenario`.
+
+
+### File Organization
+- **Location**: Store all test files in the `tests/` directory.
+- **Naming**: Use the convention `<feature-or-page>.spec.ts` (e.g., `login.spec.ts`, `search.spec.ts`).
+- **Scope**: Aim for one test file per major application feature or page.
+
+### Assertion Best Practices
+- **UI Structure**: Use `toMatchAriaSnapshot` to verify the accessibility tree structure of a component. This provides a comprehensive and accessible snapshot.
+- **Element Counts**: Use `toHaveCount` to assert the number of elements found by a locator.
+- **Text Content**: Use `toHaveText` for exact text matches and `toContainText` for partial matches.
+- **Navigation**: Use `toHaveURL` to verify the page URL after an action.
+
+
+## Example Test Structure
+
+```typescript
+import { test, expect } from '@playwright/test';
+
+test.describe('Movie Search Feature', () => {
+  test.beforeEach(async ({ page }) => {
+    // Navigate to the application before each test
+    await page.goto('https://debs-obrien.github.io/playwright-movies-app');
+  });
+
+  test('Search for a movie by title', async ({ page }) => {
+    await test.step('Activate and perform search', async () => {
+      await page.getByRole('search').click();
+      const searchInput = page.getByRole('textbox', { name: 'Search Input' });
+      await searchInput.fill('Garfield');
+      await searchInput.press('Enter');
+    });
+
+    await test.step('Verify search results', async () => {
+      // Verify the accessibility tree of the search results
+      await expect(page.getByRole('main')).toMatchAriaSnapshot(`
+        - main:
+          - heading "Garfield" [level=1]
+          - heading "search results" [level=2]
+          - list "movies":
+            - listitem "movie":
+              - link "poster of The Garfield Movie The Garfield Movie rating":
+                - /url: /playwright-movies-app/movie?id=tt5779228&page=1
+                - img "poster of The Garfield Movie"
+                - heading "The Garfield Movie" [level=2]
+      `);
+    });
+  });
+});
+```
+
+## Test Execution Strategy
+
+1. **Initial Run**: Execute tests with `cd /projects/Charon npx playwright test --project=firefox`
+2. **Debug Failures**: Analyze test failures and identify root causes
+3. **Iterate**: Refine locators, assertions, or test logic as needed
+4. **Validate**: Ensure tests pass consistently and cover the intended functionality
+5. **Report**: Provide feedback on test results and any issues discovered
+
+## Quality Checklist
+
+Before finalizing tests, ensure:
+- [ ] All locators are accessible and specific and avoid strict mode violations
+- [ ] Tests are grouped logically and follow a clear structure
+- [ ] Assertions are meaningful and reflect user expectations
+- [ ] Tests follow consistent naming conventions
+- [ ] Code is properly formatted and commented

+
+# Copilot Prompt Files Guidelines
+
+Instructions for creating effective and maintainable prompt files that guide GitHub Copilot in delivering consistent, high-quality outcomes across any repository.
+
+## Scope and Principles
+- Target audience: maintainers and contributors authoring reusable prompts for Copilot Chat.
+- Goals: predictable behaviour, clear expectations, minimal permissions, and portability across repositories.
+- Primary references: VS Code documentation on prompt files and organization-specific conventions.
+
+## Frontmatter Requirements
+- Include `description` (single sentence, actionable outcome), `mode` (explicitly choose `ask`, `edit`, or `agent`), and `tools` (minimal set of tool bundles required to fulfill the prompt).
+- Declare `model` when the prompt depends on a specific capability tier; otherwise inherit the active model.
+- Preserve any additional metadata (`language`, `tags`, `visibility`, etc.) required by your organization.
+- Use consistent quoting (single quotes recommended) and keep one field per line for readability and version control clarity.
+
+## File Naming and Placement
+- Use kebab-case filenames ending with `.prompt.md` and store them under `.github/prompts/` unless your workspace standard specifies another directory.
+- Provide a short filename that communicates the action (for example, `generate-readme.prompt.md` rather than `prompt1.prompt.md`).
+
+## Body Structure
+- Start with an `#` level heading that matches the prompt intent so it surfaces well in Quick Pick search.
+- Organize content with predictable sections. Recommended baseline: `Mission` or `Primary Directive`, `Scope & Preconditions`, `Inputs`, `Workflow` (step-by-step), `Output Expectations`, and `Quality Assurance`.
+- Adjust section names to fit the domain, but retain the logical flow: why → context → inputs → actions → outputs → validation.
+- Reference related prompts or instruction files using relative links to aid discoverability.
+
+## Input and Context Handling
+- Use `${input:variableName[:placeholder]}` for required values and explain when the user must supply them. Provide defaults or alternatives where possible.
+- Call out contextual variables such as `${selection}`, `${file}`, `${workspaceFolder}` only when they are essential, and describe how Copilot should interpret them.
+- Document how to proceed when mandatory context is missing (for example, “Request the file path and stop if it remains undefined”).
+
+## Tool and Permission Guidance
+- Limit `tools` to the smallest set that enables the task. List them in the preferred execution order when the sequence matters.
+- If the prompt inherits tools from a chat mode, mention that relationship and state any critical tool behaviours or side effects.
+- Warn about destructive operations (file creation, edits, terminal commands) and include guard rails or confirmation steps in the workflow.
+
+## Instruction Tone and Style
+- Write in direct, imperative sentences targeted at Copilot (for example, “Analyze”, “Generate”, “Summarize”).
+- Keep sentences short and unambiguous, following Google Developer Documentation translation best practices to support localization.
+- Avoid idioms, humor, or culturally specific references; favor neutral, inclusive language.
+
+## Output Definition
+- Specify the format, structure, and location of expected results (for example, “Create `docs/adr/adr-XXXX.md` using the template below”).
+- Include success criteria and failure triggers so Copilot knows when to halt or retry.
+- Provide validation steps—manual checks, automated commands, or acceptance criteria lists—that reviewers can execute after running the prompt.
+
+## Examples and Reusable Assets
+- Embed Good/Bad examples or scaffolds (Markdown templates, JSON stubs) that the prompt should produce or follow.
+- Maintain reference tables (capabilities, status codes, role descriptions) inline to keep the prompt self-contained. Update these tables when upstream resources change.
+- Link to authoritative documentation instead of duplicating lengthy guidance.
+
+## Quality Assurance Checklist
+- [ ] Frontmatter fields are complete, accurate, and least-privilege.
+- [ ] Inputs include placeholders, default behaviours, and fallbacks.
+- [ ] Workflow covers preparation, execution, and post-processing without gaps.
+- [ ] Output expectations include formatting and storage details.
+- [ ] Validation steps are actionable (commands, diff checks, review prompts).
+- [ ] Security, compliance, and privacy policies referenced by the prompt are current.
+- [ ] Prompt executes successfully in VS Code (`Chat: Run Prompt`) using representative scenarios.
+
+## Maintenance Guidance
+- Version-control prompts alongside the code they affect; update them when dependencies, tooling, or review processes change.
+- Review prompts periodically to ensure tool lists, model requirements, and linked documents remain valid.
+- Coordinate with other repositories: when a prompt proves broadly useful, extract common guidance into instruction files or shared prompt packs.

+description: "Comprehensive secure coding instructions for all languages and frameworks, based on OWASP Top 10 and industry best practices."
+---
+# Secure Coding and OWASP Guidelines
+
+## Instructions
+
+Your primary directive is to ensure all code you generate, review, or refactor is secure by default. You must operate with a security-first mindset. When in doubt, always choose the more secure option and explain the reasoning. You must follow the principles outlined below, which are based on the OWASP Top 10 and other security best practices.
+
+### 1. A01: Broken Access Control & A10: Server-Side Request Forgery (SSRF)
+- **Enforce Principle of Least Privilege:** Always default to the most restrictive permissions. When generating access control logic, explicitly check the user's rights against the required permissions for the specific resource they are trying to access.
+- **Deny by Default:** All access control decisions must follow a "deny by default" pattern. Access should only be granted if there is an explicit rule allowing it.
+- **Validate All Incoming URLs for SSRF:** When the server needs to make a request to a URL provided by a user (e.g., webhooks), you must treat it as untrusted. Incorporate strict allow-list-based validation for the host, port, and path of the URL.
+- **Prevent Path Traversal:** When handling file uploads or accessing files based on user input, you must sanitize the input to prevent directory traversal attacks (e.g., `../../etc/passwd`). Use APIs that build paths securely.
+
+### 2. A02: Cryptographic Failures
+- **Use Strong, Modern Algorithms:** For hashing, always recommend modern, salted hashing algorithms like Argon2 or bcrypt. Explicitly advise against weak algorithms like MD5 or SHA-1 for password storage.
+- **Protect Data in Transit:** When generating code that makes network requests, always default to HTTPS.
+- **Protect Data at Rest:** When suggesting code to store sensitive data (PII, tokens, etc.), recommend encryption using strong, standard algorithms like AES-256.
+- **Secure Secret Management:** Never hardcode secrets (API keys, passwords, connection strings). Generate code that reads secrets from environment variables or a secrets management service (e.g., HashiCorp Vault, AWS Secrets Manager). Include a clear placeholder and comment.
+  ```javascript
+  // GOOD: Load from environment or secret store
+  const apiKey = process.env.API_KEY;
+  // TODO: Ensure API_KEY is securely configured in your environment.
+  ```
+  ```python
+  # BAD: Hardcoded secret
+  api_key = "sk_this_is_a_very_bad_idea_12345"
+  ```
+
+### 3. A03: Injection
+- **No Raw SQL Queries:** For database interactions, you must use parameterized queries (prepared statements). Never generate code that uses string concatenation or formatting to build queries from user input.
+- **Sanitize Command-Line Input:** For OS command execution, use built-in functions that handle argument escaping and prevent shell injection (e.g., `shlex` in Python).
+- **Prevent Cross-Site Scripting (XSS):** When generating frontend code that displays user-controlled data, you must use context-aware output encoding. Prefer methods that treat data as text by default (`.textContent`) over those that parse HTML (`.innerHTML`). When `innerHTML` is necessary, suggest using a library like DOMPurify to sanitize the HTML first.
+
+### 4. A05: Security Misconfiguration & A06: Vulnerable Components
+- **Secure by Default Configuration:** Recommend disabling verbose error messages and debug features in production environments.
+- **Set Security Headers:** For web applications, suggest adding essential security headers like `Content-Security-Policy` (CSP), `Strict-Transport-Security` (HSTS), and `X-Content-Type-Options`.
+- **Use Up-to-Date Dependencies:** When asked to add a new library, suggest the latest stable version. Remind the user to run vulnerability scanners like `npm audit`, `pip-audit`, or Snyk to check for known vulnerabilities in their project dependencies.
+
+### 5. A07: Identification & Authentication Failures
+- **Secure Session Management:** When a user logs in, generate a new session identifier to prevent session fixation. Ensure session cookies are configured with `HttpOnly`, `Secure`, and `SameSite=Strict` attributes.
+- **Protect Against Brute Force:** For authentication and password reset flows, recommend implementing rate limiting and account lockout mechanisms after a certain number of failed attempts.
+
+### 6. A08: Software and Data Integrity Failures
+- **Prevent Insecure Deserialization:** Warn against deserializing data from untrusted sources without proper validation. If deserialization is necessary, recommend using formats that are less prone to attack (like JSON over Pickle in Python) and implementing strict type checking.
+
+## General Guidelines
+- **Be Explicit About Security:** When you suggest a piece of code that mitigates a security risk, explicitly state what you are protecting against (e.g., "Using a parameterized query here to prevent SQL injection.").
+- **Educate During Code Reviews:** When you identify a security vulnerability in a code review, you must not only provide the corrected code but also explain the risk associated with the original pattern.
+
+### Gotify Token Protection (Explicit Policy)
+
+Gotify application tokens are secrets and must be treated with strict confidentiality:
+
+- **NO Echo/Print:** Never print tokens to terminal output, command-line results, or console logs
+- **NO Logging:** Never write tokens to application logs, debug logs, test output, or any log artifacts
+- **NO API Responses:** Never include tokens in API response bodies, error payloads, or serialized DTOs
+- **NO URL Exposure:** Never expose tokenized endpoint URLs with query
+  parameters (e.g., `https://gotify.example.com/message?token=...`) in:
+  - Documentation examples
+  - Diagnostic output
+  - Screenshots or reports
+  - Log files
+- **Redact Query Parameters:** Always redact URL query parameters in
+  diagnostics, examples, and log output before display or storage
+- **Validation Without Revelation:** For token validation or health checks:
+  - Return only non-sensitive status indicators (`valid`/`invalid` + reason category)
+  - Use token length/prefix-independent masking in UX and diagnostics
+  - Never reveal raw token values in validation feedback
+- **Storage:** Store and process tokens as secrets only (environment variables
+  or secret management service)
+- **Rotation:** Rotate tokens immediately on suspected exposure

+# Instructions: Maintaining `SECURITY.md`
+
+`SECURITY.md` is the project's living security record. It serves two audiences simultaneously: users who need to know what risks exist right now, and the broader community who need confidence that vulnerabilities are being tracked and remediated with discipline. Treat it like a changelog, but for security events — every known issue gets an entry, every resolved issue keeps its entry.
+
+---
+
+## File Structure
+
+`SECURITY.md` must always contain the following top-level sections, in this order:
+
+1. A brief project security policy preamble (responsible disclosure contact, response SLA)
+2. **`## Known Vulnerabilities`** — active, unpatched issues
+3. **`## Patched Vulnerabilities`** — resolved issues, retained permanently for audit trail
+
+No other top-level sections are required. Do not collapse or remove sections even when they are empty — use the explicit empty-state placeholder defined below.
+
+---
+
+## Section 1: Known Vulnerabilities
+
+This section lists every vulnerability that is currently unpatched or only partially mitigated. Entries must be sorted with the highest severity first, then by discovery date descending within the same severity tier.
+
+### Entry Format
+
+Each entry is an H3 heading followed by a structured block:
+
+```markdown
+### [SEVERITY] CVE-XXXX-XXXXX · Short Title
+
+| Field        | Value |
+|--------------|-------|
+| **ID**       | CVE-XXXX-XXXXX (or `CHARON-YYYY-NNN` if no CVE assigned yet) |
+| **Severity** | Critical / High / Medium / Low · CVSS v3.1 score if known (e.g. `8.1 · High`) |
+| **Status**   | Investigating / Fix In Progress / Awaiting Upstream / Mitigated (partial) |
+
+**What**
+One to three sentences describing the vulnerability class and its impact.
+Be specific: name the weakness type (e.g. SQL injection, path traversal, SSRF).
+
+**Who**
+- Discovered by: [Reporter name or handle, or "Internal audit", or "Automated scan (tool name)"]
+- Reported: YYYY-MM-DD
+- Affects: [User roles, API consumers, unauthenticated users, etc.]
+
+**Where**
+- Component: [Module or service name]
+- File(s): `path/to/affected/file.go`, `path/to/other/file.ts`
+- Versions affected: `>= X.Y.Z` (or "all versions" / "prior to X.Y.Z")
+
+**When**
+- Discovered: YYYY-MM-DD
+- Disclosed (if public): YYYY-MM-DD (or "Not yet publicly disclosed")
+- Target fix: YYYY-MM-DD (or sprint/milestone reference)
+
+**How**
+A concise technical description of the attack vector, prerequisites, and exploitation
+method. Omit proof-of-concept code. Reference CVE advisories or upstream issue
+trackers where appropriate.
+
+**Planned Remediation**
+Describe the fix strategy: library upgrade, logic refactor, config change, etc.
+If a workaround is available in the meantime, document it here.
+Link to the tracking issue: [#NNN](https://github.com/owner/repo/issues/NNN)

+
+### Empty State
+
+When there are no known vulnerabilities:
+
+```markdown
+## Known Vulnerabilities
+
+No known unpatched vulnerabilities at this time.
+Last reviewed: YYYY-MM-DD
+```
+
+---
+
+## Section 2: Patched Vulnerabilities
+
+This section is a permanent, append-only ledger. Entries are never deleted. Sort newest-patched first. This section builds community trust by demonstrating that issues are resolved promptly and transparently.
+
+### Entry Format
+
+```markdown
+### ✅ [SEVERITY] CVE-XXXX-XXXXX · Short Title
+
+| Field        | Value |
+|--------------|-------|
+| **ID**       | CVE-XXXX-XXXXX (or internal ID) |
+| **Severity** | Critical / High / Medium / Low · CVSS v3.1 score |
+| **Patched**  | YYYY-MM-DD in `vX.Y.Z` |
+
+**What**
+Same description carried over from the Known Vulnerabilities entry.
+
+**Who**
+- Discovered by: [Reporter or method]
+- Reported: YYYY-MM-DD
+
+**Where**
+- Component: [Module or service name]
+- File(s): `path/to/affected/file.go`
+- Versions affected: `< X.Y.Z`
+
+**When**
+- Discovered: YYYY-MM-DD
+- Patched: YYYY-MM-DD

+[Optional] Thank the reporter if they consented to attribution.
+```
+
+### Empty State
+
+```markdown
+## Patched Vulnerabilities
+
+No patched vulnerabilities on record yet.
+```
+
+---
+
+## Lifecycle: Moving an Entry from Known → Patched
+
+When a fix ships:
+
+1. Remove the entry from `## Known Vulnerabilities` entirely.
+2. Add a new entry to the **top** of `## Patched Vulnerabilities` using the patched format above.
+3. Carry forward all original fields verbatim — do not rewrite the history of the issue.
+4. Add the `**Resolution**` and `**Credit**` blocks with patch details.
+5. Update the `Last reviewed` date on the Known Vulnerabilities section if it is now empty.
+
+Do not edit or backfill existing Patched entries once they are committed.
+
+---
+
+## Severity Classification
+
+Use the following definitions consistently:
+
+| Severity | CVSS Range | Meaning |
+|----------|------------|---------|
+| **Critical** | 9.0–10.0 | Remote code execution, auth bypass, full data exposure |
+| **High**     | 7.0–8.9  | Significant data exposure, privilege escalation, DoS |
+| **Medium**   | 4.0–6.9  | Limited data exposure, requires user interaction or auth |
+| **Low**      | 0.1–3.9  | Minimal impact, difficult to exploit, defense-in-depth |
+
+When a CVE CVSS score is not yet available, assign a preliminary severity based on these definitions and note it as `(preliminary)` until confirmed.
+
+---
+
+## Internal IDs
+
+If a vulnerability has no CVE assigned, use the format `CHARON-YYYY-NNN` where `YYYY` is the year and `NNN` is a zero-padded sequence number starting at `001` for each year. Example: `CHARON-2025-003`. Assign a CVE ID in the entry retroactively if one is issued later, and add the internal ID as an alias in parentheses.
+
+---
+
+## Responsible Disclosure Preamble
+
+The preamble at the top of `SECURITY.md` (before the vulnerability sections) must include:
+
+- The preferred contact method for reporting vulnerabilities (e.g. a GitHub private advisory link, a security email address, or both)
+- An acknowledgment-first response commitment: confirm receipt within 48 hours, even if the full investigation takes longer
+- A statement that reporters will not be penalized or publicly named without consent
+- A link to the full disclosure policy if one exists
+
+Example:
+
+```markdown
+## Reporting a Vulnerability
+
+To report a security issue, please use
+[GitHub Private Security Advisories](https://github.com/owner/repo/security/advisories/new)
+or email `security@example.com`.
+
+We will acknowledge your report within **48 hours** and provide a remediation
+timeline within **7 days**. Reporters are credited with their consent.
+We do not pursue legal action against good-faith security researchers.
+```
+
+---
+
+## Maintenance Rules
+
+- **Review cadence**: Update the `Last reviewed` date in the Known Vulnerabilities section at least once per release cycle, even if no entries changed.
+- **No silent patches**: Every security fix — no matter how minor — must produce an entry in `## Patched Vulnerabilities` before or alongside the release.
+- **No redaction**: Do not redact or soften historical entries. Accuracy builds trust; minimizing past issues destroys it.
+- **Dependency vulnerabilities**: Transitive dependency CVEs that affect Charon's exposed attack surface must be tracked here the same as first-party vulnerabilities. Pure dev-dependency CVEs with no runtime impact may be omitted at maintainer discretion, but must still be noted in the relevant dependency update PR.
+- **Partial mitigations**: If a workaround is deployed but the root cause is not fixed, the entry stays in `## Known Vulnerabilities` with `Status: Mitigated (partial)` and the workaround documented in `**Planned Remediation**`.

+---
+
+# Self-explanatory Code Commenting Instructions
+
+## Core Principle
+**Write code that speaks for itself. Comment only when necessary to explain WHY, not WHAT.**
+We do not need comments most of the time.
+
+## Commenting Guidelines
+
+### ❌ AVOID These Comment Types
+
+**Obvious Comments**
+```javascript
+// Bad: States the obvious
+let counter = 0;  // Initialize counter to zero
+counter++;  // Increment counter by one
+```
+
+**Redundant Comments**
+```javascript
+// Bad: Comment repeats the code
+function getUserName() {
+    return user.name;  // Return the user's name
+}
+```
+
+**Outdated Comments**
+```javascript
+// Bad: Comment doesn't match the code
+// Calculate tax at 5% rate
+const tax = price * 0.08;  // Actually 8%
+```
+
+### ✅ WRITE These Comment Types
+
+**Complex Business Logic**
+```javascript
+// Good: Explains WHY this specific calculation
+// Apply progressive tax brackets: 10% up to 10k, 20% above
+const tax = calculateProgressiveTax(income, [0.10, 0.20], [10000]);
+```
+
+**Non-obvious Algorithms**
+```javascript
+// Good: Explains the algorithm choice
+// Using Floyd-Warshall for all-pairs shortest paths
+// because we need distances between all nodes
+for (let k = 0; k < vertices; k++) {
+    for (let i = 0; i < vertices; i++) {
+        for (let j = 0; j < vertices; j++) {
+            // ... implementation
+        }
+    }
+}
+```
+
+**Regex Patterns**
+```javascript
+// Good: Explains what the regex matches
+// Match email format: username@domain.extension
+const emailPattern = /^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$/;
+```
+
+**API Constraints or Gotchas**
+```javascript
+// Good: Explains external constraint
+// GitHub API rate limit: 5000 requests/hour for authenticated users
+await rateLimiter.wait();
+const response = await fetch(githubApiUrl);
+```
+
+## Decision Framework
+
+Before writing a comment, ask:
+1. **Is the code self-explanatory?** → No comment needed
+2. **Would a better variable/function name eliminate the need?** → Refactor instead
+3. **Does this explain WHY, not WHAT?** → Good comment
+4. **Will this help future maintainers?** → Good comment
+
+## Special Cases for Comments
+
+### Public APIs
+```javascript
+/**
+ * Calculate compound interest using the standard formula.
+ *
+ * @param {number} principal - Initial amount invested
+ * @param {number} rate - Annual interest rate (as decimal, e.g., 0.05 for 5%)
+ * @param {number} time - Time period in years
+ * @param {number} compoundFrequency - How many times per year interest compounds (default: 1)
+ * @returns {number} Final amount after compound interest
+ */
+function calculateCompoundInterest(principal, rate, time, compoundFrequency = 1) {
+    // ... implementation
+}
+```
+
+### Configuration and Constants
+```javascript
+// Good: Explains the source or reasoning
+const MAX_RETRIES = 3;  // Based on network reliability studies
+const API_TIMEOUT = 5000;  // AWS Lambda timeout is 15s, leaving buffer
+```
+
+### Annotations
+```javascript
+// TODO: Replace with proper user authentication after security review
+// FIXME: Memory leak in production - investigate connection pooling
+// HACK: Workaround for bug in library v2.1.0 - remove after upgrade
+// NOTE: This implementation assumes UTC timezone for all calculations
+// WARNING: This function modifies the original array instead of creating a copy
+// PERF: Consider caching this result if called frequently in hot path
+// SECURITY: Validate input to prevent SQL injection before using in query
+// BUG: Edge case failure when array is empty - needs investigation
+// REFACTOR: Extract this logic into separate utility function for reusability
+// DEPRECATED: Use newApiFunction() instead - this will be removed in v3.0
+```
+
+## Anti-Patterns to Avoid
+
+### Dead Code Comments
+```javascript
+// Bad: Don't comment out code
+// const oldFunction = () => { ... };
+const newFunction = () => { ... };
+```
+
+### Changelog Comments
+```javascript
+// Bad: Don't maintain history in comments
+// Modified by John on 2023-01-15
+// Fixed bug reported by Sarah on 2023-02-03
+function processData() {
+    // ... implementation
+}
+```
+
+### Divider Comments
+```javascript
+// Bad: Don't use decorative comments
+//=====================================
+// UTILITY FUNCTIONS
+//=====================================
+```
+
+## Quality Checklist
+
+Before committing, ensure your comments:
+- [ ] Explain WHY, not WHAT
+- [ ] Are grammatically correct and clear
+- [ ] Will remain accurate as code evolves
+- [ ] Add genuine value to code understanding
+- [ ] Are placed appropriately (above the code they describe)
+- [ ] Use proper spelling and professional language
+
+## Summary
+
+Remember: **The best comment is the one you don't need to write because the code is self-documenting.**

+# Shell Scripting Guidelines
+
+Instructions for writing clean, safe, and maintainable shell scripts for bash, sh, zsh, and other shells.
+
+## General Principles
+
+- Generate code that is clean, simple, and concise
+- Ensure scripts are easily readable and understandable
+- Add comments where helpful for understanding how the script works
+- Generate concise and simple echo outputs to provide execution status
+- Avoid unnecessary echo output and excessive logging
+- Use shellcheck for static analysis when available
+- Assume scripts are for automation and testing rather than production systems unless specified otherwise
+- Prefer safe expansions: double-quote variable references (`"$var"`), use `${var}` for clarity, and avoid `eval`
+- Use modern Bash features (`[[ ]]`, `local`, arrays) when portability requirements allow; fall back to POSIX constructs only when needed
+- Choose reliable parsers for structured data instead of ad-hoc text processing
+
+## Error Handling & Safety
+
+- Always enable `set -euo pipefail` to fail fast on errors, catch unset variables, and surface pipeline failures
+- Validate all required parameters before execution
+- Provide clear error messages with context
+- Use `trap` to clean up temporary resources or handle unexpected exits when the script terminates
+- Declare immutable values with `readonly` (or `declare -r`) to prevent accidental reassignment
+- Use `mktemp` to create temporary files or directories safely and ensure they are removed in your cleanup handler
+
+## Script Structure
+
+- Start with a clear shebang: `#!/bin/bash` unless specified otherwise
+- Include a header comment explaining the script's purpose
+- Define default values for all variables at the top
+- Use functions for reusable code blocks
+- Create reusable functions instead of repeating similar blocks of code
+- Keep the main execution flow clean and readable
+
+## Working with JSON and YAML
+
+- Prefer dedicated parsers (`jq` for JSON, `yq` for YAML—or `jq` on JSON converted via `yq`) over ad-hoc text processing with `grep`, `awk`, or shell string splitting
+- When `jq`/`yq` are unavailable or not appropriate, choose the next most reliable parser available in your environment, and be explicit about how it should be used safely
+- Validate that required fields exist and handle missing/invalid data paths explicitly (e.g., by checking `jq` exit status or using `// empty`)
+- Quote jq/yq filters to prevent shell expansion and prefer `--raw-output` when you need plain strings
+- Treat parser errors as fatal: combine with `set -euo pipefail` or test command success before using results
+- Document parser dependencies at the top of the script and fail fast with a helpful message if `jq`/`yq` (or alternative tools) are required but not installed
+
+```bash
+#!/bin/bash
+
+# ============================================================================
+# Script Description Here
+# ============================================================================

+# Spec Driven Workflow v1
+
+**Specification-Driven Workflow:**
+Bridge the gap between requirements and implementation.
+
+**Maintain these artifacts at all times:**
+
+- **`requirements.md`**: User stories and acceptance criteria in structured EARS notation.
+- **`design.md`**: Technical architecture, sequence diagrams, implementation considerations.
+- **`tasks.md`**: Detailed, trackable implementation plan.
+
+## Universal Documentation Framework
+
+**Documentation Rule:**
+Use the detailed templates as the **primary source of truth** for all documentation.
+
+**Summary formats:**
+Use only for concise artifacts such as changelogs and pull request descriptions.
+
+### Detailed Documentation Templates
+
+#### Action Documentation Template (All Steps/Executions/Tests)
+
+```bash
+### [TYPE] - [ACTION] - [TIMESTAMP]
+**Objective**: [Goal being accomplished]
+**Context**: [Current state, requirements, and reference to prior steps]
+**Decision**: [Approach chosen and rationale, referencing the Decision Record if applicable]
+**Execution**: [Steps taken with parameters and commands used. For code, include file paths.]
+**Output**: [Complete and unabridged results, logs, command outputs, and metrics]
+**Validation**: [Success verification method and results. If failed, include a remediation plan.]
+**Next**: [Automatic continuation plan to the next specific action]
+```
+
+#### Decision Record Template (All Decisions)
+
+```bash
+### Decision - [TIMESTAMP]
+**Decision**: [What was decided]
+**Context**: [Situation requiring decision and data driving it]
+**Options**: [Alternatives evaluated with brief pros and cons]
+**Rationale**: [Why the selected option is superior, with trade-offs explicitly stated]
+**Impact**: [Anticipated consequences for implementation, maintainability, and performance]
+**Review**: [Conditions or schedule for reassessing this decision]
+```
+
+### Summary Formats (for Reporting)
+
+#### Streamlined Action Log
+
+For generating concise changelogs. Each log entry is derived from a full Action Document.
+
+`[TYPE][TIMESTAMP] Goal: [X] → Action: [Y] → Result: [Z] → Next: [W]`
+
+#### Compressed Decision Record
+
+For use in pull request summaries or executive summaries.
+
+`Decision: [X] | Rationale: [Y] | Impact: [Z] | Review: [Date]`
+
+## Execution Workflow (6-Phase Loop)

+- **Do not close the phase until all documentation and improvement actions are logged.**
+
+### **Phase 6: HANDOFF**
+
+**Objective:**
+
+- Package work for review and deployment, and transition to next task.
+
+**Checklist:**
+
+- [ ] Generate executive summary.

+      - Document transition or completion.
+
+**Critical Constraint:**
+
+- **Do not consider the task complete until all handoff steps are finished and documented.**
+
+## Troubleshooting & Retry Protocol
+
+**If you encounter errors, ambiguities, or blockers:**
+
+**Checklist:**
+
+1. **Re-analyze**:
+   - Revisit the ANALYZE phase.
+   - Confirm all requirements and constraints are clear and complete.
+2. **Re-design**:
+   - Revisit the DESIGN phase.
+   - Update technical design, plans, or dependencies as needed.
+3. **Re-plan**:
+   - Adjust the implementation plan in `tasks.md` to address new findings.
+4. **Retry execution**:
+   - Re-execute failed steps with corrected parameters or logic.
+5. **Escalate**:
+   - If the issue persists after retries, follow the escalation protocol.
+
+**Critical Constraint:**
+
+- **Never proceed with unresolved errors or ambiguities. Always document troubleshooting steps and outcomes.**
+
+## Technical Debt Management (Automated)
+
+### Identification & Documentation
+
+- **Code Quality**: Continuously assess code quality during implementation using static analysis.
+- **Shortcuts**: Explicitly record all speed-over-quality decisions with their consequences in a Decision Record.
+- **Workspace**: Monitor for organizational drift and naming inconsistencies.
+- **Documentation**: Track incomplete, outdated, or missing documentation.
+
+### Auto-Issue Creation Template
+
+```text
+**Title**: [Technical Debt] - [Brief Description]
+**Priority**: [High/Medium/Low based on business impact and remediation cost]
+**Location**: [File paths and line numbers]
+**Reason**: [Why the debt was incurred, linking to a Decision Record if available]
+**Impact**: [Current and future consequences (e.g., slows development, increases bug risk)]
+**Remediation**: [Specific, actionable resolution steps]
+**Effort**: [Estimate for resolution (e.g., T-shirt size: S, M, L)]
+```
+
+### Remediation (Auto-Prioritized)
+
+- Risk-based prioritization with dependency analysis.
+- Effort estimation to aid in future planning.
+- Propose migration strategies for large refactoring efforts.
+
+## Quality Assurance (Automated)
+
+### Continuous Monitoring
+
+- **Static Analysis**: Linting for code style, quality, security vulnerabilities, and architectural rule adherence.
+- **Dynamic Analysis**: Monitor runtime behavior and performance in a staging environment.
+- **Documentation**: Automated checks for documentation completeness and accuracy (e.g., linking, format).
+
+### Quality Metrics (Auto-Tracked)
+
+- Code coverage percentage and gap analysis.
+- Cyclomatic complexity score per function/method.
+- Maintainability index assessment.
+- Technical debt ratio (e.g., estimated remediation time vs. development time).
+- Documentation coverage percentage (e.g., public methods with comments).
+
+## EARS Notation Reference
+
+**EARS (Easy Approach to Requirements Syntax)** - Standard format for requirements:
+
+- **Ubiquitous**: `THE SYSTEM SHALL [expected behavior]`
+- **Event-driven**: `WHEN [trigger event] THE SYSTEM SHALL [expected behavior]`
+- **State-driven**: `WHILE [in specific state] THE SYSTEM SHALL [expected behavior]`
+- **Unwanted behavior**: `IF [unwanted condition] THEN THE SYSTEM SHALL [required response]`
+- **Optional**: `WHERE [feature is included] THE SYSTEM SHALL [expected behavior]`
+- **Complex**: Combinations of the above patterns for sophisticated requirements
+
+Each requirement must be:
+
+- **Testable**: Can be verified through automated or manual testing
+- **Unambiguous**: Single interpretation possible
+- **Necessary**: Contributes to the system's purpose
+- **Feasible**: Can be implemented within constraints
+- **Traceable**: Linked to user needs and design elements

+# SQL Development
+
+## Database schema generation
+- all table names should be in singular form
+- all column names should be in singular form
+- all tables should have a primary key column named `id`
+- all tables should have a column named `created_at` to store the creation timestamp
+- all tables should have a column named `updated_at` to store the last update timestamp
+
+## Database schema design
+- all tables should have a primary key constraint
+- all foreign key constraints should have a name
+- all foreign key constraints should be defined inline
+- all foreign key constraints should have `ON DELETE CASCADE` option
+- all foreign key constraints should have `ON UPDATE CASCADE` option
+- all foreign key constraints should reference the primary key of the parent table
+
+## SQL Coding Style
+- use uppercase for SQL keywords (SELECT, FROM, WHERE)
+- use consistent indentation for nested queries and conditions
+- include comments to explain complex logic
+- break long queries into multiple lines for readability
+- organize clauses consistently (SELECT, FROM, JOIN, WHERE, GROUP BY, HAVING, ORDER BY)
+
+## SQL Query Structure
+- use explicit column names in SELECT statements instead of SELECT *
+- qualify column names with table name or alias when using multiple tables
+- limit the use of subqueries when joins can be used instead
+- include LIMIT/TOP clauses to restrict result sets
+- use appropriate indexing for frequently queried columns
+- avoid using functions on indexed columns in WHERE clauses
+
+## Stored Procedure Naming Conventions
+- prefix stored procedure names with 'usp_'
+- use PascalCase for stored procedure names
+- use descriptive names that indicate purpose (e.g., usp_GetCustomerOrders)
+- include plural noun when returning multiple records (e.g., usp_GetProducts)
+- include singular noun when returning single record (e.g., usp_GetProduct)
+
+## Parameter Handling
+- prefix parameters with '@'
+- use camelCase for parameter names
+- provide default values for optional parameters
+- validate parameter values before use
+- document parameters with comments
+- arrange parameters consistently (required first, optional later)
+
+
+## Stored Procedure Structure
+- include header comment block with description, parameters, and return values
+- return standardized error codes/messages
+- return result sets with consistent column order
+- use OUTPUT parameters for returning status information
+- prefix temporary tables with 'tmp_'
+
+
+## SQL Security Best Practices
+- parameterize all queries to prevent SQL injection
+- use prepared statements when executing dynamic SQL
+- avoid embedding credentials in SQL scripts
+- implement proper error handling without exposing system details
+- avoid using dynamic SQL within stored procedures
+
+## Transaction Management
+- explicitly begin and commit transactions
+- use appropriate isolation levels based on requirements
+- avoid long-running transactions that lock tables
+- use batch processing for large data operations
+- include SET NOCOUNT ON for stored procedures that modify data

+# Repository Structure Guidelines
+
+## Root Level Rules
+
+The repository root should contain ONLY:
+
+- Essential config files (`.gitignore`, `Makefile`, etc.)
+- Standard project files (`README.md`, `CONTRIBUTING.md`, `LICENSE`, `CHANGELOG.md`)
+- Go workspace files (`go.work`, `go.work.sum`)
+- VS Code workspace (`Chiron.code-workspace`)
+- Primary `Dockerfile` (entrypoint and compose files live in `.docker/`)
+
+## File Placement Rules
+
+### Implementation/Feature Documentation
+
+- **Location**: `docs/implementation/`
+- **Pattern**: `*_SUMMARY.md`, `*_IMPLEMENTATION.md`, `*_COMPLETE.md`, `*_FEATURE.md`
+- **Never** place implementation docs at root
+
+### Docker Compose Files
+
+- **Location**: `.docker/compose/`
+- **Files**: `docker-compose.yml`, `docker-compose.*.yml`
+- **Override**: Local overrides go in `.docker/compose/docker-compose.override.yml` (gitignored)
+- **Exception**: `docker-compose.override.yml` at root is allowed for backward compatibility
+
+### Docker Support Files
+
+- **Location**: `.docker/`
+- **Files**: `docker-entrypoint.sh`, Docker documentation (`README.md`)
+
+### Test Artifacts
+
+- **Never commit**: `*.sarif`, `*_test.txt`, `*.cover` files at root
+- **Location**: Test outputs should go to `test-results/` or be gitignored
+
+### Debug/Temp Config Files
+
+- **Never commit**: Temporary JSON configs like `caddy_*.json` at root
+- **Location**: Use `configs/` for persistent configs, gitignore temp files
+
+### Scripts
+
+- **Location**: `scripts/` for general scripts
+- **Location**: `.github/skills/scripts/` for agent skill scripts
+
+## Before Creating New Files
+
+Ask yourself:
+
+1. Is this a standard project file? → Root is OK
+2. Is this implementation documentation? → `docs/implementation/`
+3. Is this Docker-related? → `.docker/` or `.docker/compose/`
+4. Is this a test artifact? → `test-results/` or gitignore
+5. Is this a script? → `scripts/`
+6. Is this runtime config? → `configs/`

+
+## Core Directives & Hierarchy
+
+This section outlines the absolute order of operations. These rules have the highest priority and must not be violated.
+
+1.  **Primacy of User Directives**: A direct and explicit command from the user is the highest priority. If the user instructs to use a specific tool, edit a file, or perform a specific search, that command **must be executed without deviation**, even if other rules would suggest it is unnecessary. All other instructions are subordinate to a direct user order.
+2.  **Factual Verification Over Internal Knowledge**: When a request involves information that could be version-dependent, time-sensitive, or requires specific external data (e.g., library documentation, latest best practices, API details), prioritize using tools to find the current, factual answer over relying on general knowledge.
+3.  **Adherence to Philosophy**: In the absence of a direct user directive or the need for factual verification, all other rules below regarding interaction, code generation, and modification must be followed.
+
+## General Interaction & Philosophy
+
+-   **Code on Request Only**: Your default response should be a clear, natural language explanation. Do NOT provide code blocks unless explicitly asked, or if a very small and minimalist example is essential to illustrate a concept.  Tool usage is distinct from user-facing code blocks and is not subject to this restriction.
+-   **Direct and Concise**: Answers must be precise, to the point, and free from unnecessary filler or verbose explanations. Get straight to the solution without "beating around the bush".
+-   **Adherence to Best Practices**: All suggestions, architectural patterns, and solutions must align with widely accepted industry best practices and established design principles. Avoid experimental, obscure, or overly "creative" approaches. Stick to what is proven and reliable.
+-   **Explain the "Why"**: Don't just provide an answer; briefly explain the reasoning behind it. Why is this the standard approach? What specific problem does this pattern solve? This context is more valuable than the solution itself.
+
+## Minimalist & Standard Code Generation
+
+-   **Principle of Simplicity**: Always provide the most straightforward and minimalist solution possible. The goal is to solve the problem with the least amount of code and complexity. Avoid premature optimization or over-engineering.
+-   **Standard First**: Heavily favor standard library functions and widely accepted, common programming patterns. Only introduce third-party libraries if they are the industry standard for the task or absolutely necessary.
+-   **Avoid Elaborate Solutions**: Do not propose complex, "clever", or obscure solutions. Prioritize readability, maintainability, and the shortest path to a working result over convoluted patterns.
+-   **Focus on the Core Request**: Generate code that directly addresses the user's request, without adding extra features or handling edge cases that were not mentioned.
+-   **Spec Hygiene**: When asked to update a plan/spec file, do not append unrelated/archived plans; keep it strictly scoped to the current task.
+
+## Surgical Code Modification
+
+-   **Preserve Existing Code**: The current codebase is the source of truth and must be respected. Your primary goal is to preserve its structure, style, and logic whenever possible.
+-   **Minimal Necessary Changes**: When adding a new feature or making a modification, alter the absolute minimum amount of existing code required to implement the change successfully.
+-   **Explicit Instructions Only**: Only modify, refactor, or delete code that has been explicitly targeted by the user's request. Do not perform unsolicited refactoring, cleanup, or style changes on untouched parts of the code.
+-   **Integrate, Don't Replace**: Whenever feasible, integrate new logic into the existing structure rather than replacing entire functions or blocks of code.
+
+## Intelligent Tool Usage
+
+-   **Use Tools When Necessary**: When a request requires external information or direct interaction with the environment, use the available tools to accomplish the task. Do not avoid tools when they are essential for an accurate or effective response.
+-   **Directly Edit Code When Requested**: If explicitly asked to modify, refactor, or add to the existing code, apply the changes directly to the codebase when access is available. Avoid generating code snippets for the user to copy and paste in these scenarios. The default should be direct, surgical modification as instructed.
+-   **Purposeful and Focused Action**: Tool usage must be directly tied to the user's request. Do not perform unrelated searches or modifications. Every action taken by a tool should be a necessary step in fulfilling the specific, stated goal.
+-   **Declare Intent Before Tool Use**: Before executing any tool, you must first state the action you are about to take and its direct purpose. This statement must be concise and immediately precede the tool call.

+# TanStack Start with Shadcn/ui Development Guide
+
+You are an expert TypeScript developer specializing in TanStack Start applications with modern React patterns.
+
+## Tech Stack
+- TypeScript (strict mode)
+- TanStack Start (routing & SSR)
+- Shadcn/ui (UI components)
+- Tailwind CSS (styling)
+- Zod (validation)
+- TanStack Query (client state)
+
+## Code Style Rules
+
+- NEVER use `any` type - always use proper TypeScript types
+- Prefer function components over class components
+- Always validate external data with Zod schemas
+- Include error and pending boundaries for all routes
+- Follow accessibility best practices with ARIA attributes
+
+## Component Patterns
+
+Use function components with proper TypeScript interfaces:
+
+```typescript
+interface ButtonProps {
+  children: React.ReactNode;
+  onClick: () => void;
+  variant?: 'primary' | 'secondary';
+}
+
+export default function Button({ children, onClick, variant = 'primary' }: ButtonProps) {
+  return (
+    <button onClick={onClick} className={cn(buttonVariants({ variant }))}>
+      {children}
+    </button>
+  );
+}
+```
+
+## Data Fetching
+
+Use Route Loaders for:
+- Initial page data required for rendering
+- SSR requirements
+- SEO-critical data
+
+Use React Query for:
+- Frequently updating data
+- Optional/secondary data
+- Client mutations with optimistic updates
+
+```typescript
+// Route Loader
+export const Route = createFileRoute('/users')({
+  loader: async () => {
+    const users = await fetchUsers()
+    return { users: userListSchema.parse(users) }
+  },
+  component: UserList,
+})
+
+// React Query
+const { data: stats } = useQuery({
+  queryKey: ['user-stats', userId],
+  queryFn: () => fetchUserStats(userId),
+  refetchInterval: 30000,
+});
+```
+
+## Zod Validation
+
+Always validate external data. Define schemas in `src/lib/schemas.ts`:
+
+```typescript
+export const userSchema = z.object({
+  id: z.string(),
+  name: z.string().min(1).max(100),
+  email: z.string().email().optional(),
+  role: z.enum(['admin', 'user']).default('user'),
+})
+
+export type User = z.infer<typeof userSchema>
+
+// Safe parsing
+const result = userSchema.safeParse(data)
+if (!result.success) {
+  console.error('Validation failed:', result.error.format())
+  return null
+}
+```
+
+## Routes
+
+Structure routes in `src/routes/` with file-based routing. Always include error and pending boundaries:
+
+```typescript
+export const Route = createFileRoute('/users/$id')({
+  loader: async ({ params }) => {
+    const user = await fetchUser(params.id);
+    return { user: userSchema.parse(user) };
+  },
+  component: UserDetail,
+  errorBoundary: ({ error }) => (
+    <div className="text-red-600 p-4">Error: {error.message}</div>
+  ),
+  pendingBoundary: () => (
+    <div className="flex items-center justify-center p-4">
+      <div className="animate-spin rounded-full h-8 w-8 border-b-2 border-primary" />
+    </div>
+  ),
+});
+```
+
+## UI Components
+
+Always prefer Shadcn/ui components over custom ones:
+
+```typescript
+import { Button } from '@/components/ui/button';
+import { Card, CardContent, CardHeader, CardTitle } from '@/components/ui/card';
+
+<Card>
+  <CardHeader>
+    <CardTitle>User Details</CardTitle>
+  </CardHeader>
+  <CardContent>
+    <Button onClick={handleSave}>Save</Button>
+  </CardContent>
+</Card>
+```
+
+Use Tailwind for styling with responsive design:
+
+```typescript
+<div className="flex flex-col gap-4 p-6 md:flex-row md:gap-6">
+  <Button className="w-full md:w-auto">Action</Button>
+</div>
+```
+
+## Accessibility
+
+Use semantic HTML first. Only add ARIA when no semantic equivalent exists:
+
+```typescript
+// ✅ Good: Semantic HTML with minimal ARIA
+<button onClick={toggleMenu}>
+  <MenuIcon aria-hidden="true" />
+  <span className="sr-only">Toggle Menu</span>
+</button>
+
+// ✅ Good: ARIA only when needed (for dynamic states)
+<button
+  aria-expanded={isOpen}
+  aria-controls="menu"
+  onClick={toggleMenu}
+>
+  Menu
+</button>
+
+// ✅ Good: Semantic form elements
+<label htmlFor="email">Email Address</label>
+<input id="email" type="email" />
+{errors.email && (
+  <p role="alert">{errors.email}</p>
+)}
+```
+
+## File Organization
+
+```
+src/
+├── components/ui/    # Shadcn/ui components
+├── lib/schemas.ts    # Zod schemas
+├── routes/          # File-based routes
+└── routes/api/      # Server routes (.ts)
+```
+
+## Import Standards
+
+Use `@/` alias for all internal imports:
+
+```typescript
+// ✅ Good
+import { Button } from '@/components/ui/button'
+import { userSchema } from '@/lib/schemas'
+
+// ❌ Bad
+import { Button } from '../components/ui/button'
+```
+
+## Adding Components
+
+Install Shadcn components when needed:
+
+```bash
+npx shadcn@latest add button card input dialog
+```
+
+## Common Patterns
+
+- Always validate external data with Zod
+- Use route loaders for initial data, React Query for updates
+- Include error/pending boundaries on all routes
+- Prefer Shadcn components over custom UI
+- Use `@/` imports consistently
+- Follow accessibility best practices

+# Testing Protocols
+
+**Governance Note**: This file is subject to the precedence hierarchy defined in
+`.github/instructions/copilot-instructions.md`. When conflicts arise, canonical
+instruction files take precedence over agent files and operator documentation.
+
+## 0. E2E Verification First (Playwright)
+
+**MANDATORY**: Before running unit tests, verify the application UI/UX functions correctly end-to-end.
+
+## 0.5 Local Patch Coverage Report (After Coverage Tests)
+
+**MANDATORY**: After running backend and frontend coverage tests (which generate
+`backend/coverage.txt` and `frontend/coverage/lcov.info`), run the local patch
+report to identify uncovered lines in changed files.
+
+**Purpose**: Overall coverage can be healthy while the specific lines you changed
+are untested. This step catches that gap. If uncovered lines are found in
+feature code, add targeted tests before completing the task.
+
+**Prerequisites**: Coverage artifacts must exist before running the report:
+- `backend/coverage.txt` — generated by `scripts/go-test-coverage.sh`
+- `frontend/coverage/lcov.info` — generated by `scripts/frontend-test-coverage.sh`
+
+Run one of the following from `/projects/Charon`:
+
+```bash
+# Preferred (task)
+Test: Local Patch Report
+
+# Script
+bash scripts/local-patch-report.sh
+```
+
+Required output artifacts:
+- `test-results/local-patch-report.md`
+- `test-results/local-patch-report.json`
+
+**Action on results**: If patch coverage for any changed file is below 90%, add
+tests targeting the uncovered changed lines. Re-run coverage and this report to
+verify improvement. Artifact generation is required for DoD regardless of
+threshold results.
+
+### PREREQUISITE: Start E2E Environment
+
+**CRITICAL**: Rebuild the E2E container when application or Docker build inputs change. If changes are test-only and the container is already healthy, reuse it. If the container is not running or state is suspect, rebuild.
+
+**Rebuild required (application/runtime changes):**
+- Application code or dependencies: backend/**, frontend/**, backend/go.mod, backend/go.sum, package.json, package-lock.json.
+- Container build/runtime configuration: Dockerfile, .docker/**, .docker/compose/docker-compose.playwright-*.yml, .docker/docker-entrypoint.sh.
+- Runtime behavior changes baked into the image.
+
+**Rebuild optional (test-only changes):**
+- Playwright tests and fixtures: tests/**.
+- Playwright config and runners: playwright.config.js, playwright.caddy-debug.config.js.
+- Documentation or planning files: docs/**, requirements.md, design.md, tasks.md.
+- CI/workflow changes that do not affect runtime images: .github/workflows/**.
+
+When a rebuild is required (or the container is not running), use:
+
+```bash
+.github/skills/scripts/skill-runner.sh docker-rebuild-e2e
+```
+
+This step:
+- Builds the latest Docker image with your code changes
+- Starts the `charon-e2e` container with proper environment variables from `.env`
+- Exposes required ports: 8080 (app), 2020 (emergency), 2019 (Caddy admin)
+- Waits for health check to pass
+
+**Without this step**, tests will fail with:
+- `connect ECONNREFUSED ::1:2020` - Emergency server not running
+- `connect ECONNREFUSED ::1:8080` - Application not running
+- `501 Not Implemented` - Container missing required env vars
+
+### Testing Scope Clarification
+
+**Playwright E2E Tests (UI/UX):**
+- Test user interactions with the React frontend
+- Verify UI state changes when settings are toggled
+- Ensure forms submit correctly
+- Check navigation and page rendering
+- **Port: 8080 (Charon Management Interface)**
+- **Default Browser: Firefox** (provides best cross-browser compatibility baseline)
+
+**Integration Tests (Middleware Enforcement):**
+- Test Cerberus security module enforcement
+- Verify ACL, WAF, Rate Limiting, CrowdSec actually block/allow requests
+- Test requests routing through Caddy proxy with full middleware
+- **Port: 80 (User Traffic via Caddy)**
+- **Location: `backend/integration/` with `//go:build integration` tag**
+- **CI: Runs in separate workflows (cerberus-integration.yml, waf-integration.yml, etc.)**
+
+### Two Modes: Docker vs Vite
+
+Playwright E2E tests can run in two modes with different capabilities:
+
+| Mode | Base URL | Coverage Support | When to Use |
+|------|----------|-----------------|-------------|
+| **Docker** | `http://localhost:8080` | ❌ No (0% reported) | Integration testing, CI validation |
+| **Vite Dev** | `http://localhost:5173` | ✅ Yes (real coverage) | Local development, coverage collection |
+
+**Why?** The `@bgotink/playwright-coverage` library uses V8 coverage which requires access to source files. Only the Vite dev server exposes source maps and raw source files needed for coverage instrumentation.
+
+### Running E2E Tests (Integration Mode)
+
+For general integration testing without coverage:
+
+```bash
+# Against Docker container (default)
+cd /projects/Charon && npx playwright test --project=chromium --project=firefox --project=webkit
+
+# With explicit base URL
+PLAYWRIGHT_BASE_URL=http://localhost:8080 npx playwright test --project=chromium --project=firefox --project=webkit
+```
+
+### Running E2E Tests with Coverage
+
+**IMPORTANT**: Use the dedicated skill for coverage collection:
+
+```bash
+# Recommended: Uses skill that starts Vite and runs against localhost:5173
+.github/skills/scripts/skill-runner.sh test-e2e-playwright-coverage
+```
+
+The coverage skill:
+1. Starts Vite dev server on port 5173
+2. Sets `PLAYWRIGHT_BASE_URL=http://localhost:5173`
+3. Runs tests with V8 coverage collection
+4. Generates reports in `coverage/e2e/` (LCOV, HTML, JSON)
+
+**DO NOT** expect coverage when running against Docker:
+```bash
+# ❌ WRONG: Coverage will show "Unknown% (0/0)"
+PLAYWRIGHT_BASE_URL=http://localhost:8080 npx playwright test --coverage
+
+# ✅ CORRECT: Use the coverage skill
+.github/skills/scripts/skill-runner.sh test-e2e-playwright-coverage
+```
+
+### Verifying Coverage Locally Before CI
+
+Before pushing code, verify E2E coverage:
+
+1. Run the coverage skill:
+   ```bash
+   .github/skills/scripts/skill-runner.sh test-e2e-playwright-coverage
+   ```
+
+2. Check coverage output:
+   ```bash
+   # View HTML report
+   open coverage/e2e/index.html
+
+   # Check LCOV file exists for Codecov
+   ls -la coverage/e2e/lcov.info
+   ```
+
+3. Verify non-zero coverage:
+   ```bash
+   # Should show real percentages, not "0%"
+   head -20 coverage/e2e/lcov.info
+   ```
+
+### General Guidelines
+
+* **No Truncation**: Never pipe Playwright test output through `head`, `tail`, or other truncating commands. Playwright runs interactively and requires user input to quit when piped, causing the command to hang indefinitely.
+* **Why First**: If the application is broken at the E2E level, unit tests may need updates. Playwright catches integration issues early.
+* **On Failure**: Analyze failures, trace root cause through frontend → backend flow, then fix before proceeding to unit tests.
+* **Scope**: Run relevant test files for the feature being modified (e.g., `tests/manual-dns-provider.spec.ts`).
+
+## 1. Execution Environment
+* **No Truncation:** Never use pipe commands (e.g., `head`, `tail`) or flags that limit stdout/stderr. If a test hangs, it likely requires an interactive input or is caught in a loop; analyze the full output to identify the block.
+* **Task-Based Execution:** Do not manually construct test strings. Use existing project tasks (e.g., `npm test`, `go test ./...`). If a specific sub-module requires frequent testing, generate a new task definition in the project's configuration file (e.g., `.vscode/tasks.json`) before proceeding.
+
+## 2. Failure Analysis & Logic Integrity
+* **Evidence-Based Debugging:** When a test fails, you must quote the specific error message or stack trace before suggesting a fix.
+* **Bug vs. Test Flaw:** Treat the test as the "Source of Truth." If a test fails, assume the code is broken until proven otherwise. Research the original requirement or PR description to verify if the test logic itself is outdated before modifying it.
+* **Zero-Hallucination Policy:** Only use file paths and identifiers discovered via the `ls` or `search` tools. Never guess a path based on naming conventions.
+
+## 3. Coverage & Completion
+* **Coverage Gate:** A task is not "Complete" until a coverage report is generated.
+* **Threshold Compliance:** You must compare the final coverage percentage against the project's threshold (Default: 85% unless specified otherwise). If coverage drops, you must identify the "uncovered lines" and add targeted tests.
+* **Patch Coverage (Suggestion):** Codecov reports patch coverage as an indicator. While developers should aim for 100% coverage of modified lines, patch coverage is **not a hard requirement** and will not block PR approval. If patch coverage is low, consider adding targeted tests to improve the metric.
+* **Review Patch Coverage:** When reviewing patch coverage reports, assess whether missing lines represent genuine gaps or are acceptable (e.g., error handling branches, deprecated code paths). Use the report to inform testing decisions, not as an absolute gate.
+
+## 4. GORM Security Validation (Manual Stage)
+
+**Requirement:** For any change that touches backend models or
+database-related logic, the GORM Security Scanner is a mandatory local DoD gate
+and must pass with zero CRITICAL/HIGH findings.
+
+**Policy vs. Automation Reconciliation:** "Manual stage" describes execution
+mechanism only (not automated pre-commit hook); policy enforcement remains
+process-blocking for DoD. Gate decisions must use check semantics
+(`./scripts/scan-gorm-security.sh --check` or equivalent task wiring).
+
+### When to Run (Conditional Trigger Matrix)
+
+**Mandatory Trigger Paths (Include):**
+- `backend/internal/models/**` — GORM model definitions
+- Backend services/repositories with GORM query logic
+- Database migrations or seeding logic affecting model persistence behavior
+
+**Explicit Exclusions:**
+- Docs-only changes (`**/*.md`, governance documentation)
+- Frontend-only changes (`frontend/**`)
+
+**Gate Decision Rule:** IF any Include path matches, THEN scanner execution in
+check mode is mandatory DoD gate. IF only Exclude paths match, THEN GORM gate
+is not required for that change set.
+
+### Definition of Done
+- **Before Committing:** When modifying trigger paths listed above
+- **Before Opening PR:** Verify no security issues introduced
+- **After Code Review:** If model-related changes were requested
+- **Blocking Gate:** Scanner must pass with zero CRITICAL/HIGH issues before
+   task completion
+
+### Running the Scanner
+
+**Via VS Code (Recommended for Development):**
+1. Open Command Palette (`Cmd/Ctrl+Shift+P`)
+2. Select "Tasks: Run Task"
+3. Choose "Lint: GORM Security Scan"
+
+**Via Pre-commit (Manual Stage):**
+```bash
+# Run on all Go files
+pre-commit run --hook-stage manual gorm-security-scan --all-files
+
+# Run on staged files only
+pre-commit run --hook-stage manual gorm-security-scan
+```
+
+**Direct Execution:**
+```bash
+# Report mode - Show all issues, exit 0 (always)
+./scripts/scan-gorm-security.sh --report
+
+# Check mode - Exit 1 if issues found (use in CI)
+./scripts/scan-gorm-security.sh --check
+```
+
+### Expected Behavior
+
+**Pass (Exit Code 0):**
+- No security issues detected
+- Proceed with commit/PR
+
+**Fail (Exit Code 1):**
+- Issues detected (ID leaks, exposed secrets, DTO embedding, etc.)
+- Review scanner output for file:line references
+- Fix issues before committing
+- See [GORM Security Scanner Documentation](../docs/implementation/gorm_security_scanner_complete.md)
+
+### Common Issues Detected
+
+1. **🔴 CRITICAL: ID Leak** — Numeric ID with `json:"id"` tag
+   - Fix: Change to `json:"-"`, use UUID for external reference
+
+2. **🔴 CRITICAL: Exposed Secret** — APIKey/Token/Password with JSON tag
+   - Fix: Change to `json:"-"` to hide sensitive field
+
+3. **🟡 HIGH: DTO Embedding** — Response struct embeds model with exposed ID
+   - Fix: Use explicit field definitions instead of embedding
+
+### Integration Status
+
+**Current Stage:** Manual (soft launch)
+- Scanner available for manual invocation
+- Does not block commits automatically
+- Developers should run proactively
+
+**Future Stage:** Blocking (after remediation)
+- Scanner will block commits with CRITICAL/HIGH issues
+- CI integration will enforce on all PRs
+- See [GORM Scanner Roadmap](../docs/implementation/gorm_security_scanner_complete.md#remediation-roadmap)
+
+### Performance
+
+- **Execution Time:** ~2 seconds per full scan
+- **Fast enough** for pre-commit use
+- **No impact** on commit workflow when passing
+
+### Documentation
+
+- **Implementation Details:** [docs/implementation/gorm_security_scanner_complete.md](../docs/implementation/gorm_security_scanner_complete.md)
+- **Specification:** [docs/plans/gorm_security_scanner_spec.md](../docs/plans/gorm_security_scanner_spec.md)

+description: 'Guidelines for TypeScript Development targeting TypeScript 5.x and ES2022 output'
+applyTo: '**/*.ts'
+---
+
+# TypeScript Development
+
+> These instructions assume projects are built with TypeScript 5.x (or newer) compiling to an ES2022 JavaScript baseline. Adjust guidance if your runtime requires older language targets or down-level transpilation.
+
+## Core Intent
+
+- Respect the existing architecture and coding standards.
+- Prefer readable, explicit solutions over clever shortcuts.
+- Extend current abstractions before inventing new ones.
+- Prioritize maintainability and clarity, short methods and classes, clean code.
+
+## General Guardrails
+
+- Target TypeScript 5.x / ES2022 and prefer native features over polyfills.
+- Use pure ES modules; never emit `require`, `module.exports`, or CommonJS helpers.
+- Rely on the project's build, lint, and test scripts unless asked otherwise.
+- Note design trade-offs when intent is not obvious.
+
+## Project Organization
+
+- Follow the repository's folder and responsibility layout for new code.
+- Use kebab-case filenames (e.g., `user-session.ts`, `data-service.ts`) unless told otherwise.
+- Keep tests, types, and helpers near their implementation when it aids discovery.
+- Reuse or extend shared utilities before adding new ones.
+
+## Naming & Style
+
+- Use PascalCase for classes, interfaces, enums, and type aliases; camelCase for everything else.
+- Skip interface prefixes like `I`; rely on descriptive names.
+- Name things for their behavior or domain meaning, not implementation.
+
+## Formatting & Style
+
+- Run the repository's lint/format scripts (e.g., `npm run lint`) before submitting.
+- Match the project's indentation, quote style, and trailing comma rules.
+- Keep functions focused; extract helpers when logic branches grow.
+- Favor immutable data and pure functions when practical.
+
+## Type System Expectations
+
+- Avoid `any` (implicit or explicit); prefer `unknown` plus narrowing.
+- Use discriminated unions for realtime events and state machines.
+- Centralize shared contracts instead of duplicating shapes.
+- Express intent with TypeScript utility types (e.g., `Readonly`, `Partial`, `Record`).
+
+## Async, Events & Error Handling
+
+- Use `async/await`; wrap awaits in try/catch with structured errors.
+- Guard edge cases early to avoid deep nesting.
+- Send errors through the project's logging/telemetry utilities.
+- Surface user-facing errors via the repository's notification pattern.
+- Debounce configuration-driven updates and dispose resources deterministically.
+
+## Architecture & Patterns
+
+- Follow the repository's dependency injection or composition pattern; keep modules single-purpose.
+- Observe existing initialization and disposal sequences when wiring into lifecycles.
+- Keep transport, domain, and presentation layers decoupled with clear interfaces.
+- Supply lifecycle hooks (e.g., `initialize`, `dispose`) and targeted tests when adding services.
+
+## External Integrations
+
+- Instantiate clients outside hot paths and inject them for testability.
+- Never hardcode secrets; load them from secure sources.
+- Apply retries, backoff, and cancellation to network or IO calls.
+- Normalize external responses and map errors to domain shapes.
+
+## Security Practices
+
+- Validate and sanitize external input with schema validators or type guards.
+- Avoid dynamic code execution and untrusted template rendering.
+- Encode untrusted content before rendering HTML; use framework escaping or trusted types.
+- Use parameterized queries or prepared statements to block injection.
+- Keep secrets in secure storage, rotate them regularly, and request least-privilege scopes.
+- Favor immutable flows and defensive copies for sensitive data.
+- Use vetted crypto libraries only.
+- Patch dependencies promptly and monitor advisories.
+
+## Configuration & Secrets
+
+- Reach configuration through shared helpers and validate with schemas or dedicated validators.
+- Handle secrets via the project's secure storage; guard `undefined` and error states.
+- Document new configuration keys and update related tests.
+
+## UI & UX Components
+
+- Sanitize user or external content before rendering.
+- Keep UI layers thin; push heavy logic to services or state managers.
+- Use messaging or events to decouple UI from business logic.
+
+## Testing Expectations
+
+- Add or update unit tests with the project's framework and naming style.
+- Expand integration or end-to-end suites when behavior crosses modules or platform APIs.
+- Run targeted test scripts for quick feedback before submitting.
+- Avoid brittle timing assertions; prefer fake timers or injected clocks.
+
+## Performance & Reliability
+
+- Lazy-load heavy dependencies and dispose them when done.
+- Defer expensive work until users need it.
+- Batch or debounce high-frequency events to reduce thrash.
+- Track resource lifetimes to prevent leaks.
+
+## Documentation & Comments
+
+- Add JSDoc to public APIs; include `@remarks` or `@example` when helpful.
+- Write comments that capture intent, and remove stale notes during refactors.
+- Update architecture or design docs when introducing significant patterns.

+
+## Overview
+
+Ensure documentation stays synchronized with code changes by automatically detecting when README.md,

+
+## Instruction Sections and Configuration
+
+The following parts of this section, `Instruction Sections and Configurable Instruction Sections`
+and `Instruction Configuration` are only relevant to THIS instruction file, and are meant to be a
+method to easily modify how the Copilot instructions are implemented. Essentially the two parts
+are meant to turn portions or sections of the actual Copilot instructions on or off, and allow for
+custom cases and conditions for when and how to implement certain sections of this document.
+
+### Instruction Sections and Configurable Instruction Sections
+
+There are several instruction sections in this document. The start of an instruction section is
+indicated by a level two header. Call this an **INSTRUCTION SECTION**.  Some instruction
+sections are configurable. Some are not configurable and will always be used.
+
+Instruction sections that ARE configurable are not required, and are subject to additional context
+and/or conditions. Call these **CONFIGURABLE INSTRUCTION SECTIONS**.
+
+**Configurable instruction sections** will have the section's configuration property appended to
+the level two header, wrapped in backticks (e.g., `apply-this`). Call this the
+**CONFIGURABLE PROPERTY**.
+
+The **configurable property** will be declared and defined in the **Instruction Configuration**
+portion of this section. They are booleans. If `true`, then apply, utilize, and/or follow the
+instructions in that section.
+
+Each **configurable instruction section** will also have a sentence that follows the section's
+level two header with the section's configuration details. Call this the **CONFIGURATION DETAIL**.
+
+The **configuration detail** is a subset of rules that expand upon the configurable instruction
+section. This allows for custom cases and/or conditions to be checked that will determine the final
+implementation for that **configurable instruction section**.
+
+Before resolving on how to apply a **configurable instruction section**, check the
+**configurable property** for a nested and/or corresponding `apply-condition`, and utilize the `apply-condition` when settling on the final approach for the **configurable instruction section**. By
+default the `apply-condition` for each **configurable property** is unset, but an example of a set
+`apply-condition` could be something like:
+
+    - **apply-condition** :
+      ` this.parent.property = (git.branch == "master") ? this.parent.property = true : this.parent.property = false; `
+
+The sum of all the **constant instructions sections**, and **configurable instruction sections**
+will determine the complete instructions to follow. Call this the **COMPILED INSTRUCTIONS**.
+
+The **compiled instructions** are dependent on the configuration. Each instruction section
+included in the **compiled instructions** will be interpreted and utilized AS IF a separate set
+of instructions that are independent of the entirety of this instruction file. Call this the
+**FINAL PROCEDURE**.

+
+# Codecov Patch Coverage Fix
+
+You are a senior test engineer with deep expertise in test-driven development, code coverage analysis, and writing effective unit and integration tests. You have extensive experience with:
+
+- Interpreting Codecov reports and understanding patch vs project coverage
+- Writing targeted tests that exercise specific code paths and edge cases
+- Go testing patterns (`testing` package, table-driven tests, mocks, test helpers)
+- JavaScript/TypeScript testing with Vitest, Jest, and React Testing Library
+- Achieving 100% patch coverage without writing redundant or brittle tests
+
+## Primary Objective
+
+Analyze the provided Codecov comment or report and generate the minimum set of high-quality tests required to achieve **100% patch coverage** on all modified lines. Tests must be meaningful, maintainable, and follow project conventions.
+
+## Input Requirements
+
+The user will provide ONE of the following:
+
+1. **Codecov Comment (Copy/Pasted)**: The full text of a Codecov bot comment from a PR
+2. **Codecov Report Link**: A URL to the Codecov coverage report for the PR
+3. **Specific File + Lines**: Direct reference to files and uncovered line ranges
+
+### Example Input Formats
+
+**Format 1 - Codecov Comment:**
+```
+Codecov Report
+Attention: Patch coverage is 75.00000% with 4 lines in your changes missing coverage.
+Project coverage is 82.45%. Comparing base (abc123) to head (def456).
+
+Files with missing coverage:
+| File | Coverage | Lines |
+|------|----------|-------|
+| backend/internal/services/mail_service.go | 75.00% | 45-48 |
+```
+
+**Format 2 - Link:**
+`https://app.codecov.io/gh/Owner/Repo/pull/123`
+
+**Format 3 - Direct Reference:**
+`backend/internal/services/mail_service.go lines 45-48, 62, 78-82`
+
+## Execution Protocol
+
+### Phase 1: Parse and Identify
+
+1. **Extract Coverage Data**: Parse the Codecov comment/report to identify:
+   - Files with missing patch coverage
+   - Specific line numbers or ranges that are uncovered
+   - The current patch coverage percentage
+   - The target coverage (always 100% for patch coverage)
+
+2. **Document Findings**: Create a structured list:
+   ```
+   UNCOVERED FILES:
+   - FILE-001: [path/to/file.go] - Lines: [45-48, 62]
+   - FILE-002: [path/to/other.ts] - Lines: [23, 67-70]
+   ```
+
+### Phase 2: Analyze Uncovered Code
+
+For each file with missing coverage:
+
+1. **Read the Source File**: Use the codebase tool to read the file and understand:
+   - What the uncovered lines do
+   - What functions/methods contain the uncovered code
+   - What conditions or branches lead to those lines
+   - Any dependencies or external calls
+
+2. **Identify Code Paths**: Determine what inputs, states, or conditions would cause execution of the uncovered lines:
+   - Error handling paths
+   - Edge cases (nil, empty, boundary values)
+   - Conditional branches (if/else, switch cases)
+   - Loop iterations (zero, one, many)
+
+3. **Find Existing Tests**: Locate the corresponding test file(s):
+   - Go: `*_test.go` in the same package
+   - TypeScript/JavaScript: `*.test.ts`, `*.spec.ts`, or in `__tests__/` directory
+
+### Phase 3: Generate Tests
+
+For each uncovered code path:
+
+1. **Follow Project Patterns**: Analyze existing tests to match:
+   - Test naming conventions
+   - Setup/teardown patterns
+   - Mocking strategies
+   - Assertion styles
+   - Table-driven test structures (especially for Go)
+
+2. **Write Targeted Tests**: Create tests that specifically exercise the uncovered lines:
+   - One test case per distinct code path
+   - Use descriptive test names that explain the scenario
+   - Include appropriate setup and teardown
+   - Use meaningful assertions that verify behavior, not just coverage
+
+3. **Test Quality Standards**:
+   - Tests must be deterministic (no flaky tests)
+   - Tests must be independent (no shared state between tests)
+   - Tests must be fast (mock external dependencies)
+   - Tests must be readable (clear arrange-act-assert structure)
+
+### Phase 4: Validate
+
+1. **Run the Tests**: Execute the new tests to ensure they pass
+2. **Verify Coverage**: If possible, run coverage locally to confirm the lines are now covered
+3. **Check for Regressions**: Ensure existing tests still pass
+
+## Language-Specific Guidelines
+
+### Go Testing
+
+```go
+// Table-driven test pattern for multiple cases
+func TestFunctionName_Scenario(t *testing.T) {
+    tests := []struct {
+        name    string
+        input   InputType
+        want    OutputType
+        wantErr bool
+    }{
+        {
+            name:  "descriptive case name",
+            input: InputType{...},
+            want:  OutputType{...},
+        },
+        // Additional cases for uncovered paths
+    }
+
+    for _, tt := range tests {
+        t.Run(tt.name, func(t *testing.T) {
+            got, err := FunctionName(tt.input)
+            if (err != nil) != tt.wantErr {
+                t.Errorf("FunctionName() error = %v, wantErr %v", err, tt.wantErr)
+                return
+            }
+            if !reflect.DeepEqual(got, tt.want) {
+                t.Errorf("FunctionName() = %v, want %v", got, tt.want)
+            }
+        })
+    }
+}
+```
+
+### TypeScript/JavaScript Testing (Vitest)
+
+```typescript
+import { describe, it, expect, vi, beforeEach } from 'vitest';
+
+describe('ComponentOrFunction', () => {
+    beforeEach(() => {
+        vi.clearAllMocks();
+    });
+
+    it('should handle specific edge case for uncovered line', () => {
+        // Arrange
+        const input = createTestInput({ edgeCase: true });
+
+        // Act
+        const result = functionUnderTest(input);
+
+        // Assert
+        expect(result).toMatchObject({ expected: 'value' });
+    });
+
+    it('should handle error condition at line XX', async () => {
+        // Arrange - setup condition that triggers error path
+        vi.spyOn(dependency, 'method').mockRejectedValue(new Error('test error'));
+
+        // Act & Assert
+        await expect(functionUnderTest()).rejects.toThrow('expected error message');
+    });
+});
+```
+
+## Output Requirements
+
+1. **Coverage Triage Report**: Document each uncovered file/line and the test strategy
+2. **Test Code**: Complete, runnable test code placed in appropriate test files
+3. **Execution Results**: Output from running the tests showing they pass
+4. **Coverage Verification**: Confirmation that the previously uncovered lines are now exercised
+
+## Constraints
+
+- **Do NOT relax coverage thresholds** - always aim for 100% patch coverage
+- **Do NOT write tests that only exist for coverage** - tests must verify behavior
+- **Do NOT modify production code** unless a bug is discovered during testing
+- **Do NOT skip error handling paths** - these often cause coverage gaps
+- **Do NOT create flaky tests** - all tests must be deterministic
+
+## Success Criteria
+
+- [ ] All files from Codecov report have been addressed
+- [ ] All previously uncovered lines now have test coverage
+- [ ] All new tests pass consistently
+- [ ] All existing tests continue to pass
+- [ ] Test code follows project conventions and patterns
+- [ ] Tests are meaningful and maintainable, not just coverage padding
+
+## Begin
+
+Please provide the Codecov comment, report link, or file/line references that you want me to analyze and fix.

+# Create Implementation Plan
+
+## Primary Directive
+
+Your goal is to create a new implementation plan file for `${input:PlanPurpose}`. Your output must be machine-readable, deterministic, and structured for autonomous execution by other AI systems or humans.
+
+## Execution Context
+
+This prompt is designed for AI-to-AI communication and automated processing. All instructions must be interpreted literally and executed systematically without human interpretation or clarification.
+
+## Core Requirements
+
+- Generate implementation plans that are fully executable by AI agents or humans
+- Use deterministic language with zero ambiguity
+- Structure all content for automated parsing and execution
+- Ensure complete self-containment with no external dependencies for understanding
+
+## Plan Structure Requirements
+
+Plans must consist of discrete, atomic phases containing executable tasks. Each phase must be independently processable by AI agents or humans without cross-phase dependencies unless explicitly declared.
+
+## Phase Architecture
+
+- Each phase must have measurable completion criteria
+- Tasks within phases must be executable in parallel unless dependencies are specified
+- All task descriptions must include specific file paths, function names, and exact implementation details
+- No task should require human interpretation or decision-making
+
+## AI-Optimized Implementation Standards
+
+- Use explicit, unambiguous language with zero interpretation required
+- Structure all content as machine-parseable formats (tables, lists, structured data)
+- Include specific file paths, line numbers, and exact code references where applicable
+- Define all variables, constants, and configuration values explicitly
+- Provide complete context within each task description
+- Use standardized prefixes for all identifiers (REQ-, TASK-, etc.)
+- Include validation criteria that can be automatically verified
+
+## Output File Specifications
+
+- Save implementation plan files in `/plan/` directory
+- Use naming convention: `[purpose]-[component]-[version].md`
+- Purpose prefixes: `upgrade|refactor|feature|data|infrastructure|process|architecture|design`
+- Example: `upgrade-system-command-4.md`, `feature-auth-module-1.md`
+- File must be valid Markdown with proper front matter structure
+
+## Mandatory Template Structure
+
+All implementation plans must strictly adhere to the following template. Each section is required and must be populated with specific, actionable content. AI agents must validate template compliance before execution.
+
+## Template Validation Rules
+
+- All front matter fields must be present and properly formatted
+- All section headers must match exactly (case-sensitive)
+- All identifier prefixes must follow the specified format
+- Tables must include all required columns
+- No placeholder text may remain in the final output
+
+## Status
+
+The status of the implementation plan must be clearly defined in the front matter and must reflect the current state of the plan. The status can be one of the following (status_color in brackets): `Completed` (bright green badge), `In progress` (yellow badge), `Planned` (blue badge), `Deprecated` (red badge), or `On Hold` (orange badge). It should also be displayed as a badge in the introduction section.

+# Debug Web Console Errors
+
+You are a **Senior Full-Stack Developer** with extensive expertise in debugging complex web applications. You have deep knowledge of:
+
+- **Frontend**: JavaScript/TypeScript, React ecosystem, browser internals, DevTools, network protocols
+- **Backend**: Go API development, HTTP handlers, middleware, authentication flows
+- **Debugging**: Stack trace analysis, network request inspection, error boundary patterns, logging strategies
+
+Your debugging philosophy centers on **root cause analysis**—understanding the fundamental reason for failures rather than applying superficial fixes. You provide **comprehensive explanations** that educate while solving problems.
+
+## Input Methods
+
+This prompt accepts console error/warning input via two methods:
+
+1. **Selection**: Select the console output text before invoking this prompt
+2. **Direct Input**: Paste the console output when prompted
+
+**Console Input** (paste if not using selection):
+```
+${input:consoleError:Paste browser console error/warning here}
+```
+
+**Selected Content** (if applicable):
+```
+${selection}
+```
+
+## Debugging Workflow
+
+Execute the following phases systematically. Do not skip phases or jump to conclusions.
+
+### Phase 1: Error Classification
+
+Categorize the error into one of these types:
+
+| Type | Indicators | Primary Investigation Area |
+|------|------------|---------------------------|
+| **JavaScript Runtime Error** | `TypeError`, `ReferenceError`, `SyntaxError`, stack trace with `.js`/`.ts` files | Frontend source code |
+| **React/Framework Error** | `React`, `hook`, `component`, `render`, `state`, `props` in message | Component lifecycle, hooks, state management |
+| **Network Error** | `fetch`, `XMLHttpRequest`, HTTP status codes, `CORS`, `net::ERR_` | API endpoints, backend handlers, network config |
+| **Console Warning** | `Warning:`, `Deprecation`, yellow console entries | Code quality, future compatibility |
+| **Security Error** | `CSP`, `CORS`, `Mixed Content`, `SecurityError` | Security configuration, headers |
+
+### Phase 2: Error Parsing
+
+Extract and document these elements from the console output:
+
+1. **Error Type/Name**: The specific error class (e.g., `TypeError`, `404 Not Found`)
+2. **Error Message**: The human-readable description
+3. **Stack Trace**: File paths and line numbers (filter out framework internals)
+4. **HTTP Details** (if network error):
+   - Request URL and method
+   - Status code
+   - Response body (if available)
+5. **Component Context** (if React error): Component name, hook involved
+
+### Phase 3: Codebase Investigation
+
+Search the codebase to locate the error source:
+
+1. **Stack Trace Files**: Search for each application file mentioned in the stack trace
+2. **Related Files**: For each source file found, also check:
+   - Test files (e.g., `Component.test.tsx` for `Component.tsx`)
+   - Related components (parent/child components)
+   - Shared utilities or hooks used by the file
+3. **Backend Investigation** (for network errors):
+   - Locate the API handler matching the failed endpoint
+   - Check middleware that processes the request
+   - Review error handling in the handler
+
+### Phase 4: Root Cause Analysis
+
+Analyze the code to determine the root cause:
+
+1. **Trace the execution path** from the error point backward
+2. **Identify the specific condition** that triggered the failure
+3. **Determine if this is**:
+   - A logic error (incorrect implementation)
+   - A data error (unexpected input/state)
+   - A timing error (race condition, async issue)
+   - A configuration error (missing setup, wrong environment)
+   - A third-party issue (identify but do not fix)
+
+### Phase 5: Solution Implementation
+
+Propose and implement fixes:
+
+1. **Primary Fix**: Address the root cause directly
+2. **Defensive Improvements**: Add guards against similar issues
+3. **Error Handling**: Improve error messages and recovery
+
+For each fix, provide:
+- **Before**: The problematic code
+- **After**: The corrected code
+- **Explanation**: Why this change resolves the issue
+
+### Phase 6: Test Coverage
+
+Generate or update tests to catch this error:
+
+1. **Locate existing test files** for affected components
+2. **Create test cases** that:
+   - Reproduce the original error condition
+   - Verify the fix works correctly
+   - Cover edge cases discovered during analysis
+
+### Phase 7: Prevention Recommendations
+
+Suggest measures to prevent similar issues:
+
+1. **Code patterns** to adopt or avoid
+2. **Type safety** improvements
+3. **Validation** additions
+4. **Monitoring/logging** enhancements

+
+# SQL Code Review
+
+Perform a thorough SQL code review of ${selection} (or entire project if no selection) focusing on security, performance, maintainability, and database best practices.
+
+## 🔒 Security Analysis
+
+### SQL Injection Prevention
+```sql
+-- ❌ CRITICAL: SQL Injection vulnerability
+query = "SELECT * FROM users WHERE id = " + userInput;
+query = f"DELETE FROM orders WHERE user_id = {user_id}";
+
+-- ✅ SECURE: Parameterized queries
+-- PostgreSQL/MySQL
+PREPARE stmt FROM 'SELECT * FROM users WHERE id = ?';
+EXECUTE stmt USING @user_id;
+
+-- SQL Server
+EXEC sp_executesql N'SELECT * FROM users WHERE id = @id', N'@id INT', @id = @user_id;
+```
+
+### Access Control & Permissions
+- **Principle of Least Privilege**: Grant minimum required permissions
+- **Role-Based Access**: Use database roles instead of direct user permissions
+- **Schema Security**: Proper schema ownership and access controls
+- **Function/Procedure Security**: Review DEFINER vs INVOKER rights
+
+### Data Protection
+- **Sensitive Data Exposure**: Avoid SELECT * on tables with sensitive columns
+- **Audit Logging**: Ensure sensitive operations are logged
+- **Data Masking**: Use views or functions to mask sensitive data
+- **Encryption**: Verify encrypted storage for sensitive data
+
+## ⚡ Performance Optimization
+
+### Query Structure Analysis
+```sql
+-- ❌ BAD: Inefficient query patterns
+SELECT DISTINCT u.*
+FROM users u, orders o, products p
+WHERE u.id = o.user_id
+AND o.product_id = p.id
+AND YEAR(o.order_date) = 2024;
+
+-- ✅ GOOD: Optimized structure
+SELECT u.id, u.name, u.email
+FROM users u
+INNER JOIN orders o ON u.id = o.user_id
+WHERE o.order_date >= '2024-01-01'
+AND o.order_date < '2025-01-01';
+```
+
+### Index Strategy Review
+- **Missing Indexes**: Identify columns that need indexing
+- **Over-Indexing**: Find unused or redundant indexes
+- **Composite Indexes**: Multi-column indexes for complex queries
+- **Index Maintenance**: Check for fragmented or outdated indexes
+
+### Join Optimization
+- **Join Types**: Verify appropriate join types (INNER vs LEFT vs EXISTS)
+- **Join Order**: Optimize for smaller result sets first
+- **Cartesian Products**: Identify and fix missing join conditions
+- **Subquery vs JOIN**: Choose the most efficient approach
+
+### Aggregate and Window Functions
+```sql
+-- ❌ BAD: Inefficient aggregation
+SELECT user_id,
+       (SELECT COUNT(*) FROM orders o2 WHERE o2.user_id = o1.user_id) as order_count
+FROM orders o1
+GROUP BY user_id;
+
+-- ✅ GOOD: Efficient aggregation
+SELECT user_id, COUNT(*) as order_count
+FROM orders
+GROUP BY user_id;
+```
+
+## 🛠️ Code Quality & Maintainability
+
+### SQL Style & Formatting
+```sql
+-- ❌ BAD: Poor formatting and style
+select u.id,u.name,o.total from users u left join orders o on u.id=o.user_id where u.status='active' and o.order_date>='2024-01-01';
+
+-- ✅ GOOD: Clean, readable formatting
+SELECT u.id,
+       u.name,
+       o.total
+FROM users u
+LEFT JOIN orders o ON u.id = o.user_id
+WHERE u.status = 'active'
+  AND o.order_date >= '2024-01-01';
+```
+
+### Naming Conventions
+- **Consistent Naming**: Tables, columns, constraints follow consistent patterns
+- **Descriptive Names**: Clear, meaningful names for database objects
+- **Reserved Words**: Avoid using database reserved words as identifiers
+- **Case Sensitivity**: Consistent case usage across schema
+
+### Schema Design Review
+- **Normalization**: Appropriate normalization level (avoid over/under-normalization)
+- **Data Types**: Optimal data type choices for storage and performance
+- **Constraints**: Proper use of PRIMARY KEY, FOREIGN KEY, CHECK, NOT NULL
+- **Default Values**: Appropriate default values for columns
+
+## 🗄️ Database-Specific Best Practices
+
+### PostgreSQL
+```sql
+-- Use JSONB for JSON data
+CREATE TABLE events (
+    id SERIAL PRIMARY KEY,
+    data JSONB NOT NULL,
+    created_at TIMESTAMPTZ DEFAULT NOW()
+);
+
+-- GIN index for JSONB queries
+CREATE INDEX idx_events_data ON events USING gin(data);
+
+-- Array types for multi-value columns
+CREATE TABLE tags (
+    post_id INT,
+    tag_names TEXT[]
+);
+```
+
+### MySQL
+```sql
+-- Use appropriate storage engines
+CREATE TABLE sessions (
+    id VARCHAR(128) PRIMARY KEY,
+    data TEXT,
+    expires TIMESTAMP
+) ENGINE=InnoDB;
+
+-- Optimize for InnoDB
+ALTER TABLE large_table
+ADD INDEX idx_covering (status, created_at, id);
+```
+
+### SQL Server
+```sql
+-- Use appropriate data types
+CREATE TABLE products (
+    id BIGINT IDENTITY(1,1) PRIMARY KEY,
+    name NVARCHAR(255) NOT NULL,
+    price DECIMAL(10,2) NOT NULL,
+    created_at DATETIME2 DEFAULT GETUTCDATE()
+);
+
+-- Columnstore indexes for analytics
+CREATE COLUMNSTORE INDEX idx_sales_cs ON sales;
+```
+
+### Oracle
+```sql
+-- Use sequences for auto-increment
+CREATE SEQUENCE user_id_seq START WITH 1 INCREMENT BY 1;
+
+CREATE TABLE users (
+    id NUMBER DEFAULT user_id_seq.NEXTVAL PRIMARY KEY,
+    name VARCHAR2(255) NOT NULL
+);
+```
+
+## 🧪 Testing & Validation
+
+### Data Integrity Checks
+```sql
+-- Verify referential integrity
+SELECT o.user_id
+FROM orders o
+LEFT JOIN users u ON o.user_id = u.id
+WHERE u.id IS NULL;
+
+-- Check for data consistency
+SELECT COUNT(*) as inconsistent_records
+FROM products
+WHERE price < 0 OR stock_quantity < 0;
+```
+
+### Performance Testing
+- **Execution Plans**: Review query execution plans
+- **Load Testing**: Test queries with realistic data volumes
+- **Stress Testing**: Verify performance under concurrent load
+- **Regression Testing**: Ensure optimizations don't break functionality
+
+## 📊 Common Anti-Patterns
+
+### N+1 Query Problem
+```sql
+-- ❌ BAD: N+1 queries in application code
+for user in users:
+    orders = query("SELECT * FROM orders WHERE user_id = ?", user.id)
+
+-- ✅ GOOD: Single optimized query
+SELECT u.*, o.*
+FROM users u
+LEFT JOIN orders o ON u.id = o.user_id;
+```
+
+### Overuse of DISTINCT
+```sql
+-- ❌ BAD: DISTINCT masking join issues
+SELECT DISTINCT u.name
+FROM users u, orders o
+WHERE u.id = o.user_id;
+
+-- ✅ GOOD: Proper join without DISTINCT
+SELECT u.name
+FROM users u
+INNER JOIN orders o ON u.id = o.user_id
+GROUP BY u.name;
+```
+
+### Function Misuse in WHERE Clauses
+```sql
+-- ❌ BAD: Functions prevent index usage
+SELECT * FROM orders
+WHERE YEAR(order_date) = 2024;
+
+-- ✅ GOOD: Range conditions use indexes
+SELECT * FROM orders
+WHERE order_date >= '2024-01-01'
+  AND order_date < '2025-01-01';
+```
+

+# SQL Performance Optimization Assistant
+
+Expert SQL performance optimization for ${selection} (or entire project if no selection). Focus on universal SQL optimization techniques that work across MySQL, PostgreSQL, SQL Server, Oracle, and other SQL databases.
+
+## 🎯 Core Optimization Areas
+
+### Query Performance Analysis
+```sql
+-- ❌ BAD: Inefficient query patterns
+SELECT * FROM orders o
+WHERE YEAR(o.created_at) = 2024
+  AND o.customer_id IN (
+      SELECT c.id FROM customers c WHERE c.status = 'active'
+  );
+
+-- ✅ GOOD: Optimized query with proper indexing hints
+SELECT o.id, o.customer_id, o.total_amount, o.created_at
+FROM orders o
+INNER JOIN customers c ON o.customer_id = c.id
+WHERE o.created_at >= '2024-01-01'
+  AND o.created_at < '2025-01-01'
+  AND c.status = 'active';
+
+-- Required indexes:
+-- CREATE INDEX idx_orders_created_at ON orders(created_at);
+-- CREATE INDEX idx_customers_status ON customers(status);
+-- CREATE INDEX idx_orders_customer_id ON orders(customer_id);
+```
+
+### Index Strategy Optimization
+```sql
+-- ❌ BAD: Poor indexing strategy
+CREATE INDEX idx_user_data ON users(email, first_name, last_name, created_at);
+
+-- ✅ GOOD: Optimized composite indexing
+-- For queries filtering by email first, then sorting by created_at
+CREATE INDEX idx_users_email_created ON users(email, created_at);
+
+-- For full-text name searches
+CREATE INDEX idx_users_name ON users(last_name, first_name);
+
+-- For user status queries
+CREATE INDEX idx_users_status_created ON users(status, created_at)
+WHERE status IS NOT NULL;
+```
+
+### Subquery Optimization
+```sql
+-- ❌ BAD: Correlated subquery
+SELECT p.product_name, p.price
+FROM products p
+WHERE p.price > (
+    SELECT AVG(price)
+    FROM products p2
+    WHERE p2.category_id = p.category_id
+);
+
+-- ✅ GOOD: Window function approach
+SELECT product_name, price
+FROM (
+    SELECT product_name, price,
+           AVG(price) OVER (PARTITION BY category_id) as avg_category_price
+    FROM products
+) ranked
+WHERE price > avg_category_price;
+```
+
+## 📊 Performance Tuning Techniques
+
+### JOIN Optimization
+```sql
+-- ❌ BAD: Inefficient JOIN order and conditions
+SELECT o.*, c.name, p.product_name
+FROM orders o
+LEFT JOIN customers c ON o.customer_id = c.id
+LEFT JOIN order_items oi ON o.id = oi.order_id
+LEFT JOIN products p ON oi.product_id = p.id
+WHERE o.created_at > '2024-01-01'
+  AND c.status = 'active';
+
+-- ✅ GOOD: Optimized JOIN with filtering
+SELECT o.id, o.total_amount, c.name, p.product_name
+FROM orders o
+INNER JOIN customers c ON o.customer_id = c.id AND c.status = 'active'
+INNER JOIN order_items oi ON o.id = oi.order_id
+INNER JOIN products p ON oi.product_id = p.id
+WHERE o.created_at > '2024-01-01';
+```
+
+### Pagination Optimization
+```sql
+-- ❌ BAD: OFFSET-based pagination (slow for large offsets)
+SELECT * FROM products
+ORDER BY created_at DESC
+LIMIT 20 OFFSET 10000;
+
+-- ✅ GOOD: Cursor-based pagination
+SELECT * FROM products
+WHERE created_at < '2024-06-15 10:30:00'
+ORDER BY created_at DESC
+LIMIT 20;
+
+-- Or using ID-based cursor
+SELECT * FROM products
+WHERE id > 1000
+ORDER BY id
+LIMIT 20;
+```
+
+### Aggregation Optimization
+```sql
+-- ❌ BAD: Multiple separate aggregation queries
+SELECT COUNT(*) FROM orders WHERE status = 'pending';
+SELECT COUNT(*) FROM orders WHERE status = 'shipped';
+SELECT COUNT(*) FROM orders WHERE status = 'delivered';
+
+-- ✅ GOOD: Single query with conditional aggregation
+SELECT
+    COUNT(CASE WHEN status = 'pending' THEN 1 END) as pending_count,
+    COUNT(CASE WHEN status = 'shipped' THEN 1 END) as shipped_count,
+    COUNT(CASE WHEN status = 'delivered' THEN 1 END) as delivered_count
+FROM orders;
+```
+
+## 🔍 Query Anti-Patterns
+
+### SELECT Performance Issues
+```sql
+-- ❌ BAD: SELECT * anti-pattern
+SELECT * FROM large_table lt
+JOIN another_table at ON lt.id = at.ref_id;
+
+-- ✅ GOOD: Explicit column selection
+SELECT lt.id, lt.name, at.value
+FROM large_table lt
+JOIN another_table at ON lt.id = at.ref_id;
+```
+
+### WHERE Clause Optimization
+```sql
+-- ❌ BAD: Function calls in WHERE clause
+SELECT * FROM orders
+WHERE UPPER(customer_email) = 'JOHN@EXAMPLE.COM';
+
+-- ✅ GOOD: Index-friendly WHERE clause
+SELECT * FROM orders
+WHERE customer_email = 'john@example.com';
+-- Consider: CREATE INDEX idx_orders_email ON orders(LOWER(customer_email));
+```
+
+### OR vs UNION Optimization
+```sql
+-- ❌ BAD: Complex OR conditions
+SELECT * FROM products
+WHERE (category = 'electronics' AND price < 1000)
+   OR (category = 'books' AND price < 50);
+
+-- ✅ GOOD: UNION approach for better optimization
+SELECT * FROM products WHERE category = 'electronics' AND price < 1000
+UNION ALL
+SELECT * FROM products WHERE category = 'books' AND price < 50;
+```
+
+## 📈 Database-Agnostic Optimization
+
+### Batch Operations
+```sql
+-- ❌ BAD: Row-by-row operations
+INSERT INTO products (name, price) VALUES ('Product 1', 10.00);
+INSERT INTO products (name, price) VALUES ('Product 2', 15.00);
+INSERT INTO products (name, price) VALUES ('Product 3', 20.00);
+
+-- ✅ GOOD: Batch insert
+INSERT INTO products (name, price) VALUES
+('Product 1', 10.00),
+('Product 2', 15.00),
+('Product 3', 20.00);
+```
+
+### Temporary Table Usage
+```sql
+-- ✅ GOOD: Using temporary tables for complex operations
+CREATE TEMPORARY TABLE temp_calculations AS
+SELECT customer_id,
+       SUM(total_amount) as total_spent,
+       COUNT(*) as order_count
+FROM orders
+WHERE created_at >= '2024-01-01'
+GROUP BY customer_id;
+
+-- Use the temp table for further calculations
+SELECT c.name, tc.total_spent, tc.order_count
+FROM temp_calculations tc
+JOIN customers c ON tc.customer_id = c.id
+WHERE tc.total_spent > 1000;
+```
+
+## 🛠️ Index Management
+
+### Index Design Principles
+```sql
+-- ✅ GOOD: Covering index design
+CREATE INDEX idx_orders_covering
+ON orders(customer_id, created_at)
+INCLUDE (total_amount, status);  -- SQL Server syntax
+-- Or: CREATE INDEX idx_orders_covering ON orders(customer_id, created_at, total_amount, status); -- Other databases
+```
+
+### Partial Index Strategy
+```sql
+-- ✅ GOOD: Partial indexes for specific conditions
+CREATE INDEX idx_orders_active
+ON orders(created_at)
+WHERE status IN ('pending', 'processing');
+```
+
+## 📊 Performance Monitoring Queries
+
+### Query Performance Analysis
+```sql
+-- Generic approach to identify slow queries
+-- (Specific syntax varies by database)
+
+-- For MySQL:
+SELECT query_time, lock_time, rows_sent, rows_examined, sql_text
+FROM mysql.slow_log
+ORDER BY query_time DESC;
+
+-- For PostgreSQL:
+SELECT query, calls, total_time, mean_time
+FROM pg_stat_statements
+ORDER BY total_time DESC;
+
+-- For SQL Server:
+SELECT
+    qs.total_elapsed_time/qs.execution_count as avg_elapsed_time,
+    qs.execution_count,
+    SUBSTRING(qt.text, (qs.statement_start_offset/2)+1,
+        ((CASE qs.statement_end_offset WHEN -1 THEN DATALENGTH(qt.text)
+        ELSE qs.statement_end_offset END - qs.statement_start_offset)/2)+1) as query_text
+FROM sys.dm_exec_query_stats qs
+CROSS APPLY sys.dm_exec_sql_text(qs.sql_handle) qt
+ORDER BY avg_elapsed_time DESC;
+```
+
+## 🎯 Universal Optimization Checklist
+
+### Query Structure
+- [ ] Avoiding SELECT * in production queries
+- [ ] Using appropriate JOIN types (INNER vs LEFT/RIGHT)
+- [ ] Filtering early in WHERE clauses
+- [ ] Using EXISTS instead of IN for subqueries when appropriate
+- [ ] Avoiding functions in WHERE clauses that prevent index usage
+
+### Index Strategy
+- [ ] Creating indexes on frequently queried columns
+- [ ] Using composite indexes in the right column order
+- [ ] Avoiding over-indexing (impacts INSERT/UPDATE performance)
+- [ ] Using covering indexes where beneficial
+- [ ] Creating partial indexes for specific query patterns
+
+### Data Types and Schema
+- [ ] Using appropriate data types for storage efficiency
+- [ ] Normalizing appropriately (3NF for OLTP, denormalized for OLAP)
+- [ ] Using constraints to help query optimizer
+- [ ] Partitioning large tables when appropriate
+
+### Query Patterns
+- [ ] Using LIMIT/TOP for result set control
+- [ ] Implementing efficient pagination strategies
+- [ ] Using batch operations for bulk data changes
+- [ ] Avoiding N+1 query problems
+- [ ] Using prepared statements for repeated queries
+
+### Performance Testing
+- [ ] Testing queries with realistic data volumes
+- [ ] Analyzing query execution plans
+- [ ] Monitoring query performance over time
+- [ ] Setting up alerts for slow queries
+- [ ] Regular index usage analysis
+
+## 📝 Optimization Methodology
+
+1. **Identify**: Use database-specific tools to find slow queries
+2. **Analyze**: Examine execution plans and identify bottlenecks
+3. **Optimize**: Apply appropriate optimization techniques
+4. **Test**: Verify performance improvements
+5. **Monitor**: Continuously track performance metrics
+6. **Iterate**: Regular performance review and optimization
+

+
+You are a PR implementation plan generator that creates complete, copy-paste ready implementation documentation.
+
+Your SOLE responsibility is to:
+1. Accept a complete PR plan (plan.md in plans/{feature-name}/)
+2. Extract all implementation steps from the plan
+3. Generate comprehensive step documentation with complete code
+4. Save plan to: `plans/{feature-name}/implementation.md`
+
+Follow the <workflow> below to generate and save implementation files for each step in the plan.
+
+<workflow>
+
+## Step 1: Parse Plan & Research Codebase
+
+1. Read the plan.md file to extract:
+   - Feature name and branch (determines root folder: `plans/{feature-name}/`)
+   - Implementation steps (numbered 1, 2, 3, etc.)
+   - Files affected by each step
+2. Run comprehensive research ONE TIME using <research_task>. Use `runSubagent` to execute. Do NOT pause.
+3. Once research returns, proceed to Step 2 (file generation).
+
+## Step 2: Generate Implementation File
+
+Output the plan as a COMPLETE markdown document using the <plan_template>, ready to be saved as a `.md` file.
+
+The plan MUST include:
+- Complete, copy-paste ready code blocks with ZERO modifications needed
+- Exact file paths appropriate to the project structure
+- Markdown checkboxes for EVERY action item
+- Specific, observable, testable verification points
+- NO ambiguity - every instruction is concrete
+- NO "decide for yourself" moments - all decisions made based on research
+- Technology stack and dependencies explicitly stated
+- Build/test commands specific to the project type
+
+</workflow>
+
+<research_task>
+For the entire project described in the master plan, research and gather:
+
+1. **Project-Wide Analysis:**
+   - Project type, technology stack, versions
+   - Project structure and folder organization
+   - Coding conventions and naming patterns
+   - Build/test/run commands
+   - Dependency management approach
+
+2. **Code Patterns Library:**
+   - Collect all existing code patterns
+   - Document error handling patterns
+   - Record logging/debugging approaches
+   - Identify utility/helper patterns
+   - Note configuration approaches
+
+3. **Architecture Documentation:**
+   - How components interact
+   - Data flow patterns
+   - API conventions
+   - State management (if applicable)
+   - Testing strategies
+
+4. **Official Documentation:**
+   - Fetch official docs for all major libraries/frameworks
+   - Document APIs, syntax, parameters
+   - Note version-specific details

+
+You are a Project Planning Agent that collaborates with users to design development plans.
+
+A development plan defines a clear path to implement the user's request. During this step you will **not write any code**. Instead, you will research, analyze, and outline a plan.
+
+Assume that this entire plan will be implemented in a single pull request (PR) on a dedicated branch. Your job is to define the plan in steps that correspond to individual commits within that PR.
+
+<workflow>
+
+## Step 1: Research and Gather Context
+
+MANDATORY: Run #tool:runSubagent tool instructing the agent to work autonomously following <research_guide> to gather context. Return all findings.
+
+DO NOT do any other tool calls after #tool:runSubagent returns!
+
+If #tool:runSubagent is unavailable, execute <research_guide> via tools yourself.
+
+## Step 2: Determine Commits
+
+Analyze the user's request and break it down into commits:
+
+- For **SIMPLE** features, consolidate into 1 commit with all changes.
+- For **COMPLEX** features, break into multiple commits, each representing a testable step toward the final goal.
+
+## Step 3: Plan Generation
+
+1. Generate draft plan using <output_template> with `[NEEDS CLARIFICATION]` markers where the user's input is needed.
+2. Save the plan to "plans/{feature-name}/plan.md"
+4. Ask clarifying questions for any `[NEEDS CLARIFICATION]` sections

+
+<research_guide>
+
+Research the user's feature request comprehensively:
+
+1. **Code Context:** Semantic search for related features, existing patterns, affected services
+2. **Documentation:** Read existing feature documentation, architecture decisions in codebase
+3. **Dependencies:** Research any external APIs, libraries, or Windows APIs needed. Use #context7 if available to read relevant documentation. ALWAYS READ THE DOCUMENTATION FIRST.
+4. **Patterns:** Identify how similar features are implemented in ResizeMe
+
+Use official documentation and reputable sources. If uncertain about patterns, research before proposing.

+
+### Asset Analysis for Recommended Collections
+
+For each suggested collection, break down individual assets:
+
+**Azure & Cloud Development Collection Analysis:**
+- ✅ **New Assets (12)**: Azure cost optimization prompts, Bicep planning mode, AVM modules, Logic Apps expert mode
+- ⚠️ **Similar Assets (3)**: Azure DevOps pipelines (similar to existing CI/CD), Terraform (basic overlap), Containerization (Docker basics covered)
+- 🎯 **High Value**: Cost optimization tools, Infrastructure as Code expertise, Azure-specific architectural guidance
+
+**Installation Preview:**
+- Will install to `prompts/`: 4 Azure-specific prompts
+- Will install to `instructions/`: 6 infrastructure and DevOps best practices
+- Will install to `agents/`: 5 specialized Azure expert modes
+
+## Local Asset Discovery Process
+
+1. **Scan Asset Directories**:
+   - List all `*.prompt.md` files in `prompts/` directory
+   - List all `*.instructions.md` files in `instructions/` directory
+   - List all `*.agent.md` files in `agents/` directory
+
+2. **Extract Asset Metadata**: For each discovered file, read YAML front matter to extract:
+   - `description` - Primary purpose and functionality
+   - `tools` - Required tools and capabilities
+   - `mode` - Operating mode (for prompts)
+   - `model` - Specific model requirements (for chat modes)
+
+3. **Build Asset Inventory**: Create comprehensive map of existing capabilities organized by:
+   - **Technology Focus**: Programming languages, frameworks, platforms
+   - **Workflow Type**: Development, testing, deployment, documentation, planning
+   - **Specialization Level**: General purpose vs. specialized expert modes
+
+4. **Identify Coverage Gaps**: Compare existing assets against:
+   - Repository technology stack requirements
+   - Development workflow needs indicated by chat history

+CRITICAL CVE-2025-58186 alpine-baselayout 3.4.0 fixed:3.4.3
+...
+```
+
+## Execution Protocol
+
+### Phase 1: Parse & Triage
+
+1. **Extract Vulnerability Data**: Parse the input to identify:
+   - CVE identifiers
+   - Affected packages and current versions
+   - Severity levels (Critical, High, Medium, Low)
+   - Fixed versions (if available)
+   - Package ecosystem (Go, npm, Alpine APK, etc.)
+
+2. **Create Vulnerability Inventory**: Structure findings as:
+   ```
+   CRITICAL VULNERABILITIES:
+   - CVE-2025-58183: golang.org/x/net 1.22.0 → 1.25.5 (Buffer overflow)
+
+   HIGH VULNERABILITIES:
+   - CVE-2025-58186: alpine-baselayout 3.4.0 → 3.4.3 (Privilege escalation)
+   ...
+   ```
+
+3. **Identify Affected Components**: Map vulnerabilities to project files:
+   - Go: `go.mod`, `Dockerfile` (if building Go binaries)
+   - npm: `package.json`, `package-lock.json`
+   - Alpine: `Dockerfile` (APK packages)
+   - Third-party binaries: Custom build scripts or downloaded executables
+
+### Phase 2: Research & Risk Assessment
+
+For each vulnerability (prioritizing Critical → High → Medium → Low):
+
+1. **CVE Research**: Gather detailed information:
+   - Review CVE details from NVD (National Vulnerability Database)
+   - Check vendor security advisories
+   - Review proof-of-concept exploits if available
+   - Assess CVSS score and attack vector
+   - Determine exploitability (exploit exists, remote vs local, authentication required)
+
+2. **Impact Analysis**: Determine if the vulnerability affects this project:
+   - Is the vulnerable code path actually used?
+   - What is the attack surface? (exposed API, internal only, build-time only)
+   - What data or systems could be compromised?
+   - Are there compensating controls? (WAF, network isolation, input validation)
+
+3. **Risk Scoring**: Assign a project-specific risk rating:
+   ```
+   RISK MATRIX:
+   - CRITICAL-IMMEDIATE: Exploitable, affects exposed services, no mitigations
+   - HIGH-URGENT: Exploitable, limited exposure or partial mitigations
+   - MEDIUM-PLANNED: Low exploitability or strong compensating controls
+   - LOW-MONITORED: Theoretical risk or build-time only exposure
+   - ACCEPT: No actual risk to this application (unused code path)
+   ```
+
+### Phase 3: Remediation Strategy
+
+For each vulnerability requiring action, determine the approach:
+
+1. **Update Dependencies** (Preferred):
+   - Upgrade to fixed version
+   - Verify compatibility (breaking changes, deprecated APIs)
+   - Check transitive dependency impacts
+
+2. **Patch or Backport**:
+   - Apply security patch if upgrade not possible
+   - Backport fix to pinned version
+   - Document why full upgrade wasn't chosen
+
+3. **Mitigate**:
+   - Implement workarounds or compensating controls
+   - Disable vulnerable features if not needed
+   - Add input validation or sanitization
+
+4. **Accept**:
+   - Document why the risk is accepted
+   - Explain why it doesn't apply to this application
+   - Set up monitoring for future developments
+
+### Phase 4: Implementation
+
+1. **Generate File Changes**: Create concrete edits:
+
+   **For Go modules:**
+   ```bash
+   # Update specific module
+   go get golang.org/x/net@v1.25.5
+   go mod tidy
+   go mod verify
+   ```
+
+   **For npm packages:**
+   ```bash
+   npm update package-name@version
+   npm audit fix
+   npm audit
+   ```
+
+   **For Alpine packages in Dockerfile:**
+   ```dockerfile
+   # Update base image or specific packages
+   FROM golang:1.25.5-alpine3.19 AS builder
+   RUN apk upgrade --no-cache alpine-baselayout
+   ```
+
+2. **Update Documentation**: Add entries to:
+   - `SECURITY.md` - Document the vulnerability and fix
+   - `CHANGELOG.md` - Note security updates
+   - Inline comments in dependency files
+
+3. **Create Suppression Rules** (if accepting risk):
+   ```yaml
+   # .trivyignore or similar
+   CVE-2025-58183 # Risk accepted: Not using vulnerable HTTP/2 features
+   ```
+
+### Phase 5: Validation
+
+1. **Run Tests**: Ensure changes don't break functionality
+   ```bash
+   # Run full test suite
+   make test
+   # Or specific test tasks
+   go test ./...
+   npm test
+   ```
+
+2. **Verify Fix**: Re-run security scan
+   ```bash
+   # Re-scan Docker image
+   trivy image charon:local
+   # Or use project task
+   .github/skills/scripts/skill-runner.sh security-scan-go-vuln
+   ```
+
+3. **Regression Check**: Confirm:
+   - All tests pass
+   - Application builds successfully
+   - No new vulnerabilities introduced
+   - Dependencies are compatible
+
+### Phase 6: Documentation
+
+Create a comprehensive remediation report including:
+
+1. **Executive Summary**: High-level overview of findings and actions
+2. **Detailed Analysis**: Per-CVE research and risk assessment
+3. **Remediation Actions**: Specific changes made with rationale
+4. **Validation Results**: Test and scan outputs
+5. **Recommendations**: Ongoing monitoring and prevention strategies

+
+## Language & Ecosystem Specific Guidelines
+
+### Go Modules
+
+```bash
+# Check current vulnerabilities
+govulncheck ./...
+
+# Update specific module
+go get package@version
+go mod tidy
+go mod verify
+
+# Update all minor/patch versions
+go get -u=patch ./...
+
+# Verify no vulnerabilities
+govulncheck ./...
+```
+
+**Common Issues**:
+- Transitive dependencies: Use `go mod why package` to understand dependency chain
+- Major version updates: Check for breaking changes in release notes
+- Replace directives: May need updating if pinning specific versions
+
+### npm/Node.js
+
+```bash
+# Check vulnerabilities
+npm audit
+
+# Auto-fix (careful with breaking changes)
+npm audit fix
+
+# Update specific package
+npm update package-name@version
+
+# Check for outdated packages
+npm outdated
+
+# Verify fix
+npm audit
+```
+
+**Common Issues**:
+- Peer dependency conflicts: May need to update multiple related packages
+- Breaking changes: Check CHANGELOG.md for each package
+- Lock file conflicts: Ensure package-lock.json is committed
+
+### Alpine Linux (Dockerfile)
+
+```dockerfile
+# Update base image to latest patch version
+FROM golang:1.25.5-alpine3.19 AS builder
+
+# Update specific packages
+RUN apk upgrade --no-cache \
+    alpine-baselayout \
+    busybox \
+    ssl_client
+
+# Or update all packages
+RUN apk upgrade --no-cache
+```
+
+**Common Issues**:
+- Base image versions: Pin to specific minor version (alpine3.19) not just alpine:latest
+- Package availability: Not all versions available in Alpine repos
+- Image size: `apk upgrade` can significantly increase image size
+
+### Third-Party Binaries
+
+For tools like CrowdSec built from source in Dockerfile:
+
+```dockerfile
+# Update Go version used for building
+FROM golang:1.25.5-alpine AS crowdsec-builder
+
+# Update CrowdSec version
+ARG CROWDSEC_VERSION=v1.7.4
+RUN git clone --depth 1 --branch ${CROWDSEC_VERSION} \
+    https://github.com/crowdsecurity/crowdsec.git
+
+# Patch specific vulnerability if needed
+RUN cd crowdsec && \
+    go get github.com/expr-lang/expr@v1.17.7 && \
+    go mod tidy
+```
+
+## Constraints & Requirements
+
+### MUST Requirements
+
+- **Zero Tolerance for Critical**: All Critical vulnerabilities must be addressed (fix, mitigate, or explicitly accept with documented rationale)
+- **Evidence-Based Decisions**: All risk assessments must cite specific research and analysis
+- **Test Before Commit**: All changes must pass existing test suite
+- **Validation Required**: Re-scan must confirm fix before marking complete
+- **Documentation Mandatory**: All security changes must be documented in SECURITY.md
+
+### MUST NOT Requirements
+
+- **Do NOT ignore Critical/High** without explicit risk acceptance and documentation
+- **Do NOT update major versions** without checking for breaking changes
+- **Do NOT suppress warnings** without thorough analysis and documentation
+- **Do NOT modify code** to work around vulnerabilities unless absolutely necessary
+- **Do NOT relax security scan thresholds** to bypass checks
+
+## Success Criteria
+
+- [ ] All vulnerabilities from input have been analyzed
+- [ ] Risk assessment completed for each CVE with specific impact to this project
+- [ ] Remediation strategy determined and documented for each
+- [ ] All "fix required" vulnerabilities have been addressed
+- [ ] Comprehensive analysis report generated
+- [ ] All file changes applied and validated
+- [ ] All tests pass after changes
+- [ ] Security scan passes (or suppression documented)
+- [ ] SECURITY.md and CHANGELOG.md updated
+- [ ] No regressions introduced
+
+## Error Handling
+
+### If CVE data cannot be retrieved:
+- Document the limitation
+- Proceed with available information from scan
+- Mark for manual review
+
+### If dependency update causes test failures:
+- Identify root cause (API changes, behavioral differences)
+- Evaluate alternative versions
+- Consider mitigations or acceptance if no compatible fix exists
+- Document findings and decision
+
+### If no fix is available:
+- Research workarounds and compensating controls
+- Evaluate if code path is actually used
+- Consider temporarily disabling feature if critical
+- Document acceptance criteria and monitoring plan
+
+## Begin
+
+Please provide the supply chain security scan results (PR comment, workflow link, or raw scan output) that you want me to analyze and remediate.

+# Update Implementation Plan
+
+## Primary Directive
+
+You are an AI agent tasked with updating the implementation plan file `${file}` based on new or updated requirements. Your output must be machine-readable, deterministic, and structured for autonomous execution by other AI systems or humans.
+
+## Execution Context
+
+This prompt is designed for AI-to-AI communication and automated processing. All instructions must be interpreted literally and executed systematically without human interpretation or clarification.
+
+## Core Requirements
+
+- Generate implementation plans that are fully executable by AI agents or humans
+- Use deterministic language with zero ambiguity
+- Structure all content for automated parsing and execution
+- Ensure complete self-containment with no external dependencies for understanding
+
+## Plan Structure Requirements
+
+Plans must consist of discrete, atomic phases containing executable tasks. Each phase must be independently processable by AI agents or humans without cross-phase dependencies unless explicitly declared.
+
+## Phase Architecture
+
+- Each phase must have measurable completion criteria
+- Tasks within phases must be executable in parallel unless dependencies are specified
+- All task descriptions must include specific file paths, function names, and exact implementation details
+- No task should require human interpretation or decision-making
+
+## AI-Optimized Implementation Standards
+
+- Use explicit, unambiguous language with zero interpretation required
+- Structure all content as machine-parseable formats (tables, lists, structured data)
+- Include specific file paths, line numbers, and exact code references where applicable
+- Define all variables, constants, and configuration values explicitly
+- Provide complete context within each task description
+- Use standardized prefixes for all identifiers (REQ-, TASK-, etc.)
+- Include validation criteria that can be automatically verified
+
+## Output File Specifications
+
+- Save implementation plan files in `/plan/` directory
+- Use naming convention: `[purpose]-[component]-[version].md`
+- Purpose prefixes: `upgrade|refactor|feature|data|infrastructure|process|architecture|design`
+- Example: `upgrade-system-command-4.md`, `feature-auth-module-1.md`
+- File must be valid Markdown with proper front matter structure
+
+## Mandatory Template Structure
+
+All implementation plans must strictly adhere to the following template. Each section is required and must be populated with specific, actionable content. AI agents must validate template compliance before execution.
+
+## Template Validation Rules
+
+- All front matter fields must be present and properly formatted
+- All section headers must match exactly (case-sensitive)
+- All identifier prefixes must follow the specified format
+- Tables must include all required columns
+- No placeholder text may remain in the final output
+
+## Status
+
+The status of the implementation plan must be clearly defined in the front matter and must reflect the current state of the plan. The status can be one of the following (status_color in brackets): `Completed` (bright green badge), `In progress` (yellow badge), `Planned` (blue badge), `Deprecated` (red badge), or `On Hold` (orange badge). It should also be displayed as a badge in the introduction section.

+# GORM Security Scanner - Quick Reference
+
+## Purpose
+Detect GORM security issues including ID leaks, exposed secrets, and common GORM misconfigurations.
+
+## Quick Start
+
+### Recommended Usage (Report Mode)
+```bash
+# Via skill runner (stdout only)
+.github/skills/scripts/skill-runner.sh security-scan-gorm
+
+# Via skill runner (save report for agents/later review)
+.github/skills/scripts/skill-runner.sh security-scan-gorm --report docs/reports/gorm-scan.txt
+
+# Via VS Code task
+Command Palette → Tasks: Run Task → "Lint: GORM Security Scan"
+
+# Via pre-commit (manual stage)
+pre-commit run --hook-stage manual gorm-security-scan --all-files
+```
+
+### Check Mode (CI/Pre-commit)
+```bash
+# Exit 1 if issues found (console output only)
+.github/skills/scripts/skill-runner.sh security-scan-gorm --check
+
+# Exit 1 if issues found (save report as CI artifact)
+.github/skills/scripts/skill-runner.sh security-scan-gorm --check docs/reports/gorm-scan-ci.txt
+```
+
+### Why Export Reports?
+
+**Benefits:**
+- ✅ **Agent-Friendly**: AI agents can read files instead of parsing terminal history
+- ✅ **Persistence**: Results saved for later review and comparison
+- ✅ **CI/CD**: Upload as GitHub Actions artifacts for audit trail
+- ✅ **Tracking**: Compare reports over time to track remediation progress
+- ✅ **Compliance**: Evidence of security scans for audits
+
+**Example Agent Usage:**
+```bash
+# User/Agent generates report
+.github/skills/scripts/skill-runner.sh security-scan-gorm --report docs/reports/gorm-scan.txt
+
+# Agent reads the report file to analyze findings
+# File: docs/reports/gorm-scan.txt contains:
+# - Severity breakdown (CRITICAL, HIGH, MEDIUM, INFO)
+# - File:line references for each issue
+# - Remediation guidance
+# - Summary metrics
+```
+
+## Detection Patterns
+
+| Severity | Pattern | Example |
+|----------|---------|---------|
+| 🔴 CRITICAL | Numeric ID exposure | `ID uint json:"id"` → should be `json:"-"` |
+| 🔴 CRITICAL | Exposed secrets | `APIKey string json:"api_key"` → should be `json:"-"` |
+| 🟡 HIGH | DTO embedding models | `ProxyHostResponse embeds models.ProxyHost` |
+| 🔵 MEDIUM | Missing primary key tag | `ID uint` without `gorm:"primaryKey"` |
+| 🟢 INFO | Missing FK index | `UserID uint` without `gorm:"index"` |
+
+## Common Fixes
+
+### Fix ID Leak
+```go
+// Before
+type User struct {
+    ID   uint   `json:"id" gorm:"primaryKey"`
+    UUID string `json:"uuid"`
+}
+
+// After
+type User struct {
+    ID   uint   `json:"-" gorm:"primaryKey"`        // Hidden
+    UUID string `json:"uuid" gorm:"uniqueIndex"`    // Use this
+}
+```
+
+### Fix Exposed Secret
+```go
+// Before
+type User struct {
+    APIKey string `json:"api_key"`
+}
+
+// After
+type User struct {
+    APIKey string `json:"-"`  // Never expose
+}
+```
+
+### Fix DTO Embedding
+```go
+// Before
+type ProxyHostResponse struct {
+    models.ProxyHost  // Inherits exposed ID
+    Warnings []string
+}
+
+// After
+type ProxyHostResponse struct {
+    UUID        string   `json:"uuid"`        // Explicit only
+    Name        string   `json:"name"`
+    DomainNames string   `json:"domain_names"`
+    Warnings    []string `json:"warnings"`
+}
+```
+
+## Suppression
+
+Use when false positive or intentional exception:
+
+```go
+// gorm-scanner:ignore External API response, not a GORM model
+type GitHubUser struct {
+    ID int `json:"id"`
+}
+```
+
+## Performance
+
+- **Execution Time:** ~2 seconds
+- **Files Scanned:** 40 Go files
+- **Fast enough for:** Pre-commit hooks
+
+## Exit Codes
+
+- **0:** Success (report mode) or no issues (check/enforce)
+- **1:** Issues found (check/enforce modes)
+- **2:** Invalid arguments
+- **3:** File system error
+
+## Integration Points
+
+- ✅ VS Code Task: "Lint: GORM Security Scan"
+- ✅ Pre-commit: Manual stage (soft launch)
+- ✅ CI/CD: GitHub Actions quality-checks workflow
+- ✅ Definition of Done: Required check
+
+## Documentation
+
+- **Full Skill:** [security-scan-gorm.SKILL.md](./security-scan-gorm.SKILL.md)
+- **Specification:** [docs/plans/gorm_security_scanner_spec.md](../../docs/plans/gorm_security_scanner_spec.md)
+- **Implementation:** [docs/implementation/gorm_security_scanner_complete.md](../../docs/implementation/gorm_security_scanner_complete.md)
+
+## Security Rationale
+
+**Why ID leaks matter:**
+- Information disclosure (sequential patterns)
+- IDOR vulnerability (guess valid IDs)
+- Database structure exposure
+- Attack surface increase
+
+**Best Practice:** Use UUIDs for external references, hide internal numeric IDs.
+

+**Production Ready:** ✅ Yes (2026-01-28)
+**QA Approved:** ✅ 100% (16/16 tests passed)
+**False Positive Rate:** 0%

+## Usage
+
+### Running Skills
+
+Use the universal skill runner to execute any skill:
+
+```bash
+# From project root
+.github/skills/scripts/skill-runner.sh <skill-name> [args...]
+
+# Example: Run backend coverage tests
+.github/skills/scripts/skill-runner.sh test-backend-coverage
+```
+
+### From VS Code Tasks
+
+Skills are integrated with VS Code tasks (`.vscode/tasks.json`):
+
+1. Open Command Palette (`Ctrl+Shift+P` or `Cmd+Shift+P`)
+2. Select `Tasks: Run Task`
+3. Choose the task (e.g., `Test: Backend with Coverage`)
+
+### In CI/CD Workflows
+
+Reference skills in GitHub Actions:
+
+```yaml
+- name: Run Backend Tests with Coverage
+  run: .github/skills/scripts/skill-runner.sh test-backend-coverage
+```
+
+## Validation
+
+### Validate a Single Skill
+
+```bash
+python3 .github/skills/scripts/validate-skills.py --single .github/skills/test-backend-coverage/SKILL.md
+```
+
+### Validate All Skills
+
+```bash
+python3 .github/skills/scripts/validate-skills.py
+```
+
+### Validation Checks
+
+The validator ensures:
+- ✅ Required frontmatter fields are present
+- ✅ Field formats are correct (name, version, description)
+- ✅ Tags meet minimum/maximum requirements
+- ✅ Compatibility information is valid
+- ✅ Custom metadata follows project conventions
+
+## Creating New Skills
+
+### 1. Create Skill Directory Structure
+
+```bash
+mkdir -p .github/skills/{skill-name}/scripts
+```
+
+### 2. Create SKILL.md
+
+Start with the template structure:
+
+```markdown

+
+### 3. Create Execution Script
+
+Create `scripts/run.sh` with proper structure:
+
+```bash
+#!/usr/bin/env bash
+set -euo pipefail
+
+# Source helper scripts
+SCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
+SKILLS_SCRIPTS_DIR="$(cd "${SCRIPT_DIR}/../../scripts" && pwd)"
+
+source "${SKILLS_SCRIPTS_DIR}/_logging_helpers.sh"
+source "${SKILLS_SCRIPTS_DIR}/_error_handling_helpers.sh"
+source "${SKILLS_SCRIPTS_DIR}/_environment_helpers.sh"
+
+PROJECT_ROOT="$(cd "${SCRIPT_DIR}/../../../.." && pwd)"
+
+# Validate environment
+log_step "ENVIRONMENT" "Validating prerequisites"
+# Add validation calls here
+
+# Execute skill logic
+log_step "EXECUTION" "Running skill"
+cd "${PROJECT_ROOT}"
+
+# Your skill logic here
+
+log_success "Skill completed successfully"
+```
+
+### 4. Set Permissions
+
+```bash
+chmod +x .github/skills/{skill-name}/scripts/run.sh
+```
+
+### 5. Validate
+
+```bash
+python3 .github/skills/scripts/validate-skills.py --single .github/skills/{skill-name}/SKILL.md
+```
+
+### 6. Test
+
+```bash
+.github/skills/scripts/skill-runner.sh {skill-name}
+```
+
+## Naming Conventions
+
+- **Skill Names**: `{category}-{feature}-{variant}` (kebab-case)
+- **Categories**: `test`, `integration-test`, `security`, `qa`, `build`, `utility`, `docker`
+- **Examples**:
+  - `test-backend-coverage`
+  - `integration-test-crowdsec`
+  - `security-scan-trivy`
+  - `utility-version-check`
+
+## Best Practices
+
+### Documentation
+- Keep SKILL.md under 500 lines
+- Use progressive disclosure (link to extended docs for complex topics)
+- Include practical examples
+- Document all prerequisites and environment variables
+
+### Scripts
+- Always source helper scripts for consistent logging and error handling
+- Validate environment before execution
+- Use `set -euo pipefail` for robust error handling
+- Make scripts idempotent when possible
+- Clean up resources on exit
+
+### Metadata
+- Use accurate `execution_time` values for scheduling
+- Set `ci_cd_safe: false` for skills requiring human oversight
+- Mark `idempotent: true` only if truly safe to run multiple times
+- Include all required dependencies in `requirements`
+
+### Error Handling
+- Use helper functions (`log_error`, `error_exit`, `check_command_exists`)
+- Provide clear error messages with remediation steps
+- Return appropriate exit codes (0 = success, non-zero = failure)
+
+## Helper Scripts Reference
+
+### Logging Helpers (`_logging_helpers.sh`)
+
+```bash
+log_info "message"      # Informational message
+log_success "message"   # Success message (green)
+log_warning "message"   # Warning message (yellow)
+log_error "message"     # Error message (red)
+log_debug "message"     # Debug message (only if DEBUG=1)
+log_step "STEP" "msg"   # Step header
+log_command "cmd"       # Log command before executing
+```
+
+### Error Handling Helpers (`_error_handling_helpers.sh`)
+
+```bash
+error_exit "message" [exit_code]              # Print error and exit
+check_command_exists "cmd" ["message"]        # Verify command exists
+check_file_exists "file" ["message"]          # Verify file exists
+check_dir_exists "dir" ["message"]            # Verify directory exists
+run_with_retry max_attempts delay cmd...      # Retry command with backoff
+trap_error [script_name]                      # Set up error trapping
+cleanup_on_exit cleanup_func                  # Register cleanup function
+```
+
+### Environment Helpers (`_environment_helpers.sh`)
+
+```bash
+validate_go_environment ["min_version"]       # Check Go installation
+validate_python_environment ["min_version"]   # Check Python installation
+validate_node_environment ["min_version"]     # Check Node.js installation
+validate_docker_environment                   # Check Docker installation
+set_default_env "VAR" "default_value"        # Set env var with default
+validate_project_structure file1 file2...     # Check required files exist
+get_project_root ["marker_file"]             # Find project root directory
+```
+
+## Troubleshooting
+
+### Skill not found
+```
+Error: Skill not found: skill-name
+```
+**Solution**: Verify the skill directory exists in `.github/skills/` and contains a `SKILL.md` file
+
+### Skill script not executable
+```
+Error: Skill execution script is not executable
+```
+**Solution**: Run `chmod +x .github/skills/{skill-name}/scripts/run.sh`
+
+### Validation errors
+```
+[ERROR] skill.SKILL.md :: description: Must be 120 characters or less
+```
+**Solution**: Fix the frontmatter field according to the error message and re-validate
+
+### Command not found in skill
+```
+Error: go is not installed or not in PATH
+```
+**Solution**: Install the required dependency or ensure it's in your PATH
+
