fix(ci): force push nightly branch to handle divergence from development

fix(docker): update GeoLite2-Country.mmdb checksum + automation

Fixes critical Docker build failure caused by upstream GeoLite2 database
update without corresponding Dockerfile checksum update.

**Root Cause:**
- GeoLite2-Country.mmdb file updated upstream
- Dockerfile still referenced old SHA256 checksum
- Build aborted at checksum verification (line 352)
- Cascade "blob not found" errors for all COPY commands

**Changes:**
- Update Dockerfile ARG GEOLITE2_COUNTRY_SHA256 to current value
- Add automated weekly checksum update workflow (.github/workflows/update-geolite2.yml)
- Implement error handling: retry logic, format validation, failure notifications
- Document rollback decision matrix with 10 failure scenarios
- Create comprehensive maintenance guide (docs/maintenance/geolite2-checksum-update.md)
- Update CHANGELOG.md and README.md with maintenance references

**Verification:**
- Checksum verified against current upstream file: 436135ee...
- Pre-commit hooks: PASSED (EOF/whitespace auto-fixed)
- Trivy security scan: PASSED (no critical/high issues)
- Dockerfile syntax: VALID
- GitHub Actions YAML: VALID
- No hardcoded secrets or injection vulnerabilities

**Automation Features:**
- Weekly scheduled checks (Monday 2 AM UTC)
- Auto-PR creation when checksum changes
- GitHub issue creation on workflow failure
- Comprehensive error handling and retry logic

**Impact:**
- Unblocks all CI/CD Docker image builds
- Enables publishing to GHCR/Docker Hub
- Prevents future checksum failures via automation
- Zero application code changes (no regression risk)

**Documentation:**
- Implementation plan: docs/plans/geolite2_checksum_fix_spec.md
- QA report: docs/reports/qa_geolite2_checksum_fix.md
- Maintenance guide: docs/maintenance/geolite2-checksum-update.md

**Supervisor Recommendations Implemented:**
- #1: Checksum freshness verification before update
- #3: Rollback decision criteria (10 scenarios)
- #4: Automated workflow error handling

-# 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.

-1.  **Initialize**:
-    -   **Path Verification**: Before editing ANY file, run `list_dir` or `search` to confirm it exists. Do not rely on your memory.

-
-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.

-description: Security Engineer and QA specialist focused on breaking the implementation.
-argument-hint: The feature or endpoint to audit (e.g., "Audit the new Proxy Host creation flow")
-
-
----
-You are a SECURITY ENGINEER and QA SPECIALIST.
-Your job is to act as an ADVERSARY. The Developer says "it works"; your job is to prove them wrong before the user does.
-
-<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)
-</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?
-
-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.

-## 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>
-- **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`.
-- **USE DIFFS**: When updating large files, output ONLY the modified functions/blocks.

-## 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.

-<workflow>
+## Your Mission: Prevent 3AM Deployment Disasters
 
-1.  **Discovery (The "What Broke?" Phase)**:
-    -   **Read Instructions**: Read `.github/instructions` and `.github/DevOps.agent.md`.
-    -   **List Runs**: Run `gh run list --limit 3`. Identify the `run-id` of the failure.
-    -   **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.
+Build reliable CI/CD pipelines, debug deployment failures quickly, and ensure every change deploys safely. Focus on automation, monitoring, and rapid recovery.
 
-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)**.
+## Step 1: Triage Deployment Failures
 
-    - **Case A: Infrastructure Failure**:
-        - **Action**: YOU fix this. Edit the workflow or Dockerfile directly.
-        - **Verify**: Commit, push, and watch the run.
+**Mandatory** Make sure implementation follows best practices outlined in `.github/instructions/github-actions-ci-cd-best-practices.instructions.md`.
 
-    - **Case B: Application Failure**:
-        - **Action**: STOP. You are strictly forbidden from editing application code.
-        - **Output**: Generate a **Bug Report** using the format below.
+**When investigating a failure, ask:**
 
-3. **Remediation (If Case A)**:
-    - Edit the `.github/workflows/*.yml` or `Dockerfile`.
-    - Commit and push.
+1. **What changed?**
+   - "What commit/PR triggered this?"
+   - "Dependencies updated?"
+   - "Infrastructure changes?"
 
-</workflow>
+2. **When did it break?**
+   - "Last successful deploy?"
+   - "Pattern of failures or one-time?"
 
-<coverage_and_ci>
-**Coverage Tests in CI**: GitHub Actions workflows run coverage tests automatically:
-- `.github/workflows/codecov-upload.yml`: Uploads coverage to Codecov
-- `.github/workflows/quality-checks.yml`: Enforces coverage thresholds
+3. **Scope of impact?**
+   - "Production down or staging?"
+   - "Partial failure or complete?"
+   - "How many users affected?"
 
-**Your Role as DevOps**:
-- You do NOT write coverage tests (that's `Backend_Dev` and `Frontend_Dev`).
-- You DO ensure CI workflows run coverage scripts correctly.
-- You DO verify that coverage thresholds match local requirements (85% by default).
-- If CI coverage fails but local tests pass, check for:
-    1. Different `CHARON_MIN_COVERAGE` values between local and CI
-    2. Missing test files in CI (check `.gitignore`, `.dockerignore`)
-    3. Race condition timeouts (check `PERF_MAX_MS_*` environment variables)
-</coverage_and_ci>
+4. **Can we rollback?**
+   - "Is previous version stable?"
+   - "Data migration complications?"

-(Only use this if handing off to a Developer Agent)
+## Step 2: Common Failure Patterns & Solutions
 
-## 🐛 CI Failure Report
-
-**Offending File**: `{path/to/file}`
-**Job Name**: `{name of failing job}`
-**Error Log**:
-
-```text
-{paste the specific error lines here}
+### **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?
+
+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.

 <workflow>
 
-1.  **Initialize**:
-    -   **Read Instructions**: Read `.github/instructions` and `.github/Frontend_Dev.agent.md`.
-    -   **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).
+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/`
 
-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.
+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. **Verification (Quality Gates)**:
-    - **Gate 1: Static Analysis (CRITICAL)**:
-        - **Type Check (MANDATORY)**: Run the VS Code task "Lint: TypeScript Check" or execute `npm run type-check`.
-            - **Why**: This check is in manual stage of pre-commit for performance. You MUST run it explicitly before completing your task.
-            - **STOP**: If *any* errors appear, you **MUST** fix them immediately. Do not say "I'll leave this for later."
-        - **Lint**: Run `npm run lint`.
-            - This runs automatically in pre-commit, but verify locally before final submission.
-    - **Gate 2: Logic**:
-        - Run `npm run test:ci`.
-    - **Gate 3: Coverage (MANDATORY)**:
-        - **VS Code Task**: Use "Test: Frontend with Coverage" (recommended)
-        - **Manual Script**: Execute `/projects/Charon/scripts/frontend-test-coverage.sh` from the root directory
-        - **Minimum**: 85% coverage (configured via `CHARON_MIN_COVERAGE` or `CPM_MIN_COVERAGE`)
-        - **Critical**: If coverage drops below threshold, write additional tests immediately. Do not skip this step.
-        - **Why**: Coverage tests are in manual stage of pre-commit for performance. You MUST run them via VS Code tasks or scripts before completing your task.
-        - 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.
-    - **Gate 4: Pre-commit**:
-        - Run `pre-commit run --all-files` as final check (this runs fast hooks only; coverage and type-check were verified above).
+3. **Testing**:
+   - 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 `npm run lint` to check for linting issues
+   - Run `npm run typecheck` for TypeScript errors
+   - Ensure accessibility with proper ARIA attributes

-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
+<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/instructions` and `.github/Planning.agent.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.
+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
 
-2.  **Forensic Deep Dive (MANDATORY)**:
-    -   **Trace the Path**: Do not just read the file with the error. You must trace the data flow upstream (callers) and downstream (callees).
-    -   **Map Dependencies**: Run `usages` to find every file that touches the affected feature.
-    -   **Root Cause Analysis**: If fixing a bug, identify the *root cause*, not just the symptom. Ask: "Why was the data malformed before it got here?"
-    -   **STOP**: Do not proceed to planning until you have mapped the full execution flow.
+2. **Design Phase**:
+   - 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
 
-3. **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.
-
-4. **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.
-
-5. **Review**:
-    - Ask the Management agent for review.
+3. **Documentation**:
+   - Write plan to `docs/plans/current_spec.md`
+   - Include acceptance criteria
+   - Break down into implementable tasks
+   - Estimate complexity for each component
 
+4. **Handoff**:
+   - Once plan is approved, delegate to Backend_Dev and Frontend_Dev
+   - Provide clear context and references

-
-  1. Build tests for coverage of perposed code additions and chages based on how the code SHOULD work

-  2. UI: {Components in src/components}
-  3. Tests: {Unit tests to verify UX states}
-  4. Triage any issues found during testing
-
-### 🕵️ Phase 3: QA & Security
-
-  1. Edge Cases: {List specific scenarios to test}
-  2. **Coverage Tests (MANDATORY)**:
-     - Backend: Run VS Code task "Test: Backend with Coverage" or execute `scripts/go-test-coverage.sh`
-     - Frontend: Run VS Code task "Test: Frontend with Coverage" or execute `scripts/frontend-test-coverage.sh`
-     - Minimum coverage: 85% for both backend and frontend
-     - **Critical**: These are in manual stage of pre-commit for performance. Agents MUST run them via VS Code tasks or scripts before marking tasks complete.
-  3. Security: Run CodeQL and Trivy scans. Triage and fix any new errors or warnings.
-  4. **Type Safety (Frontend)**: Run VS Code task "Lint: TypeScript Check" or execute `cd frontend && npm run type-check`
-  5. Linting: Run `pre-commit` hooks on all files and triage anything not auto-fixed.

 <constraints>
 
-- NO HALLUCINATIONS: Do not guess file paths. Verify them.
-
-- 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.
-
-- New Code and Edits: Don't just suggest adding or editing code. Deep research all possible impacts and dependencies before making changes. If X file is changed, what other files are affected? Do those need changes too? New code and partial edits are both leading causes of bugs when the entire scope isn't considered.
-
-- Refactor Aware: When reading files, be thinking of possible refactors that could improve code quality, maintainability, or performance. Suggest those as part of the plan if relevant. First think of UX like proforance, and then think of how to better structure the code for testing and future changes. Include those suggestions in the plan.
-
-- Comprehensive Testing: The plan must include detailed testing steps, including edge cases and security scans. Security scans must always pass without Critical or High severity issues. Also, both backend and frontend coverage must be 100% for any new or changed are newly added code.
-
-- Ignore Files: Always keep the .gitignore, .dockerignore, and .codecove.yml files in mind when suggesting new files or directories.
-
-- Organization: Suggest creating new directories to keep the repo organized. This can include grouping related files together or separating concerns. Include already existing files in the new structure if relevant. Keep track in /docs/plans/structure.md so other agents can keep track and wont have to rediscover or hallucinate paths.
-
+- **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

-1.  **Reconnaissance**:
-    -   **Read Instructions**: Read `.github/instructions` and `.github/QA_Security.agent.md`.
-    -   **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.
+1. **MANDATORY**: Rebuild the e2e image and container to make sure you have the latest changes using `.github/skills/scripts/skill-runner.sh docker-rebuild-e2e`. Rebuild every time code changes are made before running tests again.
 
-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?
+2. **Test Analysis**:
+   - Review existing test coverage
+   - Identify gaps in test coverage
+   - Review test failure outputs with `test_failure` tool
 
-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 `.github/skills`, `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.
+3. **Security Scanning**:
+   - Run Trivy scans on filesystem and container images
+   - Analyze vulnerabilities with `mcp_trivy_mcp_findings_list`

-## DEFINITION OF DONE ##
-
-The task is not complete until ALL of the following pass with zero issues:
-
-1. **Coverage Tests (MANDATORY - Run Explicitly)**:
-    - **Backend**: Run VS Code task "Test: Backend with Coverage" or execute `scripts/go-test-coverage.sh`
-    - **Frontend**: Run VS Code task "Test: Frontend with Coverage" or execute `scripts/frontend-test-coverage.sh`
-    - **Why**: These are in manual stage of pre-commit for performance. You MUST run them via VS Code tasks or scripts.
-    - Minimum coverage: 85% for both backend and frontend.
-    - All tests must pass with zero failures.
-
-2. **Type Safety (Frontend)**:
-    - Run VS Code task "Lint: TypeScript Check" or execute `cd frontend && npm run type-check`
-    - **Why**: This check is in manual stage of pre-commit for performance. You MUST run it explicitly.
-    - Fix all type errors immediately.
-
-3. **Pre-commit Hooks**: Run `pre-commit run --all-files` (this runs fast hooks only; coverage was verified in step 1)
-
-4. **Security Scans**:
-    - CodeQL: Run as VS Code task or via GitHub Actions
-    - Trivy: Run as VS Code task or via Docker
-    - Zero issues allowed
-
-5. **Linting**: All language-specific linters must pass (Go vet, ESLint, markdownlint)
-
-**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>
 
-- **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`.
-- **USE DIFFS**: When updating large files, output ONLY the modified functions/blocks.
-- **NO PARTIAL FIXES**: If an issue is found, write tests to prove it. Do not fix it yourself. Report back to Management or the appropriate Dev subagent.
-- **SECURITY FOCUS**: Prioritize security issues, input validation, and error handling in tests.
-- **EDGE CASES**: Always think of edge cases and unexpected inputs. Write tests to cover these scenarios.
-- **TEST FIRST**: Always write tests that prove an issue exists. Do not write tests to pass the code as-is. If the code is broken, your tests should fail until it's fixed by Dev.
-- **NO MOCKING**: Avoid mocking dependencies unless absolutely necessary. Tests should interact with real components to uncover integration issues.
+- **PRIORITIZE CRITICAL/HIGH**: Always address CRITICAL and HIGH severity issues first
+- **NO FALSE POSITIVES**: Verify findings before reporting
+- **ACTIONABLE REPORTS**: Every finding must include remediation steps
+- **COMPLETE COVERAGE**: Aim for 85%+ code coverage on critical paths

-## Your Core Mandate
-Your goal is not to do the work, but to prevent 'Agent Drift'—where agents make decisions in isolation that harm the overall project integrity.
-You ensure that plans are robust, data contracts are sound, and best practices are followed before any code is written.
 <workflow>
 
-  -   **Read Instructions**: Read `.github/instructions` and `.github/Management.agent.md`.
-  -   **Read Spec**: Read `docs/plans/current_spec.md` and or any relevant plan documents.
-  -   **Critical Analysis**:
-      -   **Plan Completeness**: Does the plan cover all edge cases? Are there any missing components or unclear requirements?
-      -   **Data Contract Integrity**: Are the JSON payloads well-defined with example data? Do they align with best practices for API design?
-      -   **Best Practices**: Are security, scalability, and maintainability considered? Are there any risky shortcuts proposed?
-      -   **Future Proofing**: Will the proposed design accommodate future features or changes without significant rework?
-      -   **Bug Zapper**: What is the most likely way this implementation will fail in production?
+1. **Understand Changes**:
+   - Use `get_changed_files` to see what was modified
+   - Read the PR description and linked issues
+   - Understand the intent behind the changes
 
+2. **Code Review**:
+   - Check for adherence to project conventions
+   - Verify error handling is appropriate
+   - Review for security vulnerabilities (OWASP Top 10)
+   - Check for performance implications
+   - Ensure tests cover the changes
+   - Verify documentation is updated
+
+3. **Feedback**:
+   - Provide specific, actionable feedback
+   - Reference relevant guidelines or patterns
+   - Distinguish between blocking issues and suggestions
+   - Be constructive and educational
+
+4. **Approval**:
+   - Only approve when all blocking issues are resolved
+   - Verify CI checks pass
+   - Ensure the change aligns with project goals
 </workflow>
 
-## Operational Rules
-1. **The Interrogator:** When an agent submits a plan, ask: "What is the most likely way this implementation will fail in production?"
-2. **Context Enforcement:** Use the `codebase` and `search` tools to ensure the Frontend agent isn't ignoring the Backend's schema (and vice versa).
-3. **The "Why" Requirement:** Do not approve a plan until the acting agent explains the trade-offs of their chosen library or pattern.
-4. **Socratic Guardrails:** If an agent proposes a risky shortcut (e.g., skipping validation), do not correct the code. Instead, ask: "How does this approach affect our data integrity long-term?"
-5. **Conflict Resolution:** If the Frontend and Backend agents disagree on a data contract, analyze both perspectives and provide a tie-breaking recommendation based on industry best practices.
+<constraints>
+
+- **READ-ONLY**: Do not modify code, only review and provide feedback
+- **CONSTRUCTIVE**: Focus on improvement, not criticism

+- Use the `use()` hook for promise handling and async data fetching
+- Implement forms with Actions API and `useFormStatus` for loading states
+- Use `useOptimistic` for optimistic UI updates during async operations
+- Use `useActionState` for managing action state and form submissions
+- Leverage `useEffectEvent()` to extract non-reactive logic from effects (React 19.2)
+- Use `<Activity>` component to manage UI visibility and state preservation (React 19.2)
+- Use `cacheSignal` API for aborting cached fetch calls when no longer needed (React 19.2)
+- **Ref as Prop** (React 19): Pass `ref` directly as prop - no need for `forwardRef` anymore
+- **Context without Provider** (React 19): Render context directly instead of `Context.Provider`
+- Implement Server Components for data-heavy components when using frameworks like Next.js
+- Mark Client Components explicitly with `'use client'` directive when needed
+- Use `startTransition` for non-urgent updates to keep the UI responsive
+- Leverage Suspense boundaries for async data fetching and code splitting
+- No need to import React in every file - new JSX transform handles it
+- Use strict TypeScript with proper interface design and discriminated unions
+- Implement proper error boundaries for graceful error handling
+- Use semantic HTML elements (`<button>`, `<nav>`, `<main>`, etc.) for accessibility
+- Ensure all interactive elements are keyboard accessible

+import { use, Suspense } from "react";
+
+interface User {
+  id: number;
+  name: string;
+  email: string;
+}
+
+async function fetchUser(id: number): Promise<User> {
+  const res = await fetch(`https://api.example.com/users/${id}`);
+  if (!res.ok) throw new Error("Failed to fetch user");
+  return res.json();
+}
+
+function UserProfile({ userPromise }: { userPromise: Promise<User> }) {
+  // use() hook suspends rendering until promise resolves
+  const user = use(userPromise);
+
+  return (
+    <div>
+      <h2>{user.name}</h2>
+      <p>{user.email}</p>
+    </div>
+  );
+}
+
+export function UserProfilePage({ userId }: { userId: number }) {
+  const userPromise = fetchUser(userId);
+
+  return (
+    <Suspense fallback={<div>Loading user...</div>}>
+      <UserProfile userPromise={userPromise} />
+    </Suspense>
+  );
+}
+```
+
+### Form with Actions and useFormStatus (React 19)
+
+```typescript
+import { useFormStatus } from "react-dom";
+import { useActionState } from "react";
+
+// Submit button that shows pending state
+function SubmitButton() {
+  const { pending } = useFormStatus();
+
+  return (
+    <button type="submit" disabled={pending}>
+      {pending ? "Submitting..." : "Submit"}
+    </button>
+  );
+}
+
+interface FormState {
+  error?: string;
+  success?: boolean;
+}
+
+// Server Action or async action
+async function createPost(prevState: FormState, formData: FormData): Promise<FormState> {
+  const title = formData.get("title") as string;
+  const content = formData.get("content") as string;
+
+  if (!title || !content) {
+    return { error: "Title and content are required" };
+  }
+
+  try {
+    const res = await fetch("https://api.example.com/posts", {
+      method: "POST",
+      headers: { "Content-Type": "application/json" },
+      body: JSON.stringify({ title, content }),
+    });
+
+    if (!res.ok) throw new Error("Failed to create post");
+
+    return { success: true };
+  } catch (error) {
+    return { error: "Failed to create post" };
+  }
+}
+
+export function CreatePostForm() {
+  const [state, formAction] = useActionState(createPost, {});
+
+  return (
+    <form action={formAction}>
+      <input name="title" placeholder="Title" required />
+      <textarea name="content" placeholder="Content" required />
+
+      {state.error && <p className="error">{state.error}</p>}
+      {state.success && <p className="success">Post created!</p>}
+
+      <SubmitButton />
+    </form>
+  );
+}
+```
+
+### Optimistic Updates with useOptimistic (React 19)
+
+```typescript

+    body: JSON.stringify({ text }),
+  });
+  return res.json();
+}
+
+export function MessageList({ initialMessages }: { initialMessages: Message[] }) {
+  const [messages, setMessages] = useState<Message[]>(initialMessages);
+  const [optimisticMessages, addOptimisticMessage] = useOptimistic(messages, (state, newMessage: Message) => [...state, newMessage]);
+  const [isPending, startTransition] = useTransition();
+
+  const handleSend = async (text: string) => {
+    const tempMessage: Message = {
+      id: `temp-${Date.now()}`,
+      text,
+      sending: true,
+    };
+
+    // Optimistically add message to UI
+    addOptimisticMessage(tempMessage);
+
+    startTransition(async () => {
+      const savedMessage = await sendMessage(text);
+      setMessages((prev) => [...prev, savedMessage]);
+    });
+  };
+
+  return (
+    <div>
+      {optimisticMessages.map((msg) => (
+        <div key={msg.id} className={msg.sending ? "opacity-50" : ""}>
+          {msg.text}
+        </div>
+      ))}
+      <MessageInput onSend={handleSend} disabled={isPending} />
+    </div>
+  );
+}
+```
+
+### Using useEffectEvent (React 19.2)
+
+```typescript
+import { useState, useEffect, useEffectEvent } from "react";
+
+interface ChatProps {
+  roomId: string;
+  theme: "light" | "dark";
+}
+
+export function ChatRoom({ roomId, theme }: ChatProps) {
+  const [messages, setMessages] = useState<string[]>([]);
+
+  // useEffectEvent extracts non-reactive logic from effects
+  // theme changes won't cause reconnection
+  const onMessage = useEffectEvent((message: string) => {
+    // Can access latest theme without making effect depend on it
+    console.log(`Received message in ${theme} theme:`, message);
+    setMessages((prev) => [...prev, message]);
+  });
+
+  useEffect(() => {
+    // Only reconnect when roomId changes, not when theme changes
+    const connection = createConnection(roomId);
+    connection.on("message", onMessage);
+    connection.connect();
+
+    return () => {
+      connection.disconnect();
+    };
+  }, [roomId]); // theme not in dependencies!
+
+  return (
+    <div className={theme}>
+      {messages.map((msg, i) => (
+        <div key={i}>{msg}</div>
+      ))}
+    </div>
+  );
+}
+```
+
+### Using <Activity> Component (React 19.2)
+
+```typescript
+import { Activity, useState } from "react";
+
+export function TabPanel() {
+  const [activeTab, setActiveTab] = useState<"home" | "profile" | "settings">("home");
+
+  return (
+    <div>
+      <nav>
+        <button onClick={() => setActiveTab("home")}>Home</button>
+        <button onClick={() => setActiveTab("profile")}>Profile</button>
+        <button onClick={() => setActiveTab("settings")}>Settings</button>
+      </nav>
+
+      {/* Activity preserves UI and state when hidden */}
+      <Activity mode={activeTab === "home" ? "visible" : "hidden"}>
+        <HomeTab />
+      </Activity>
+
+      <Activity mode={activeTab === "profile" ? "visible" : "hidden"}>

+
+      <Activity mode={activeTab === "settings" ? "visible" : "hidden"}>
+        <SettingsTab />
+      </Activity>
+    </div>
+  );
+}
+
+function HomeTab() {
+  // State is preserved when tab is hidden and restored when visible
+  const [count, setCount] = useState(0);
+
+  return (
+    <div>
+      <p>Count: {count}</p>
+      <button onClick={() => setCount(count + 1)}>Increment</button>
+    </div>
+  );
+}
+```
+
+### Custom Hook with TypeScript Generics
+
+```typescript
+import { useState, useEffect } from "react";
+
+interface UseFetchResult<T> {
+  data: T | null;
+  loading: boolean;
+  error: Error | null;
+  refetch: () => void;
+}
+
+export function useFetch<T>(url: string): UseFetchResult<T> {
+  const [data, setData] = useState<T | null>(null);
+  const [loading, setLoading] = useState(true);
+  const [error, setError] = useState<Error | null>(null);
+  const [refetchCounter, setRefetchCounter] = useState(0);
+
+  useEffect(() => {

+
+# 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="Tuesday, June 3, 2025">3</button>
+  <button role="gridcell" tabindex="-1" aria-label="Wednesday, June 4, 2025">4</button>
+  <button role="gridcell" tabindex="-1" aria-label="Thursday, June 5, 2025">5</button>

+  <button role="gridcell" tabindex="-1" aria-label="Thursday, June 19, 2025">19</button>
+  <button role="gridcell" tabindex="-1" aria-label="Friday, June 20, 2025">20</button>

+  <button role="gridcell" tabindex="-1" aria-label="Wednesday, June 25, 2025">25</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
+│   └── helper.ps1        # PowerShell 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.

+- 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
+- **Documentation**: Comment why specific tools are required for complex configurations
+
+## 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
+```
+```

+## Prompt Engineering Tips
+
+When performing a code review, apply these prompt engineering principles from the [GitHub Copilot documentation](https://docs.github.com/en/copilot/concepts/prompting/prompt-engineering):
+
+1. **Start General, Then Get Specific**: Begin with high-level architecture review, then drill into implementation details
+2. **Give Examples**: Reference similar patterns in the codebase when suggesting changes
+3. **Break Complex Tasks**: Review large PRs in logical chunks (security → tests → logic → style)
+4. **Avoid Ambiguity**: Be specific about which file, line, and issue you're addressing
+5. **Indicate Relevant Code**: Reference related code that might be affected by changes
+6. **Experiment and Iterate**: If initial review misses something, review again with focused questions
+
+## Project Context

 Before marking an implementation task as complete, perform the following in order:
 
-1. **Pre-Commit Triage**: Run `pre-commit run --all-files`.
+1. **Playwright E2E Tests** (MANDATORY - Run First):
+    - **Run**: `npx playwright test --project=chromium` 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
+
+2. **Security Scans** (MANDATORY - Zero Tolerance):
+    - **CodeQL Go Scan**: Run VS Code task "Security: CodeQL Go Scan (CI-Aligned)" OR `pre-commit run codeql-go-scan --all-files`
+        - 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 `pre-commit run codeql-js-scan --all-files`

+        - Medium/low findings should be documented and triaged
+    - **Validate Findings**: Run `pre-commit run codeql-check-findings --all-files` 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`

     - If errors occur, **fix them immediately**.
     - If logic errors occur, analyze and propose a fix.
     - Do not output code that violates pre-commit standards.

+    - 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)

+# 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.

+# 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

+## 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

+## 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

+# 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
+.SECONDARY:
+
+# Delete targets if recipe fails
+.DELETE_ON_ERROR:
+
+# Preserve specific files
+.PRECIOUS: %.o
+```
+
+## Common Patterns
+
+### Standard Project Structure
+
+```makefile
+CC = gcc
+CFLAGS = -Wall -O2
+objects = main.o utils.o parser.o
+
+.PHONY: all clean install
+
+all: program
+
+program: $(objects)
+	$(CC) -o $@ $^
+
+%.o: %.c
+	$(CC) $(CFLAGS) -c $< -o $@
+
+clean:
+	-rm -f program $(objects)
+
+install: program
+	install -d $(PREFIX)/bin
+	install -m 755 program $(PREFIX)/bin
+```
+
+### Managing Multiple Programs
+
+```makefile
+programs = prog1 prog2 prog3
+
+.PHONY: all clean
+
+all: $(programs)
+
+prog1: prog1.o common.o
+	$(CC) -o $@ $^
+
+prog2: prog2.o common.o
+	$(CC) -o $@ $^
+
+prog3: prog3.o
+	$(CC) -o $@ $^
+
+clean:
+	-rm -f $(programs) *.o
+```
+
+## Anti-Patterns to Avoid
+
+- Don't start recipe lines with spaces instead of tabs
+- Avoid hardcoding file lists when they can be generated with wildcards or functions
+- Don't use `$(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

+
+# 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.

+### Testing Scope: E2E vs Integration
+
+**CRITICAL:** Playwright E2E tests verify **UI/UX functionality** on the Charon management interface (port 8080). They should NOT test middleware enforcement behavior.
+
+#### What E2E Tests SHOULD Cover
+
+✅ **User Interface Interactions:**
+- Form submissions and validation
+- Navigation and routing
+- Visual state changes (toggles, badges, status indicators)
+- Authentication flows (login, logout, session management)
+- CRUD operations via the management API
+- Responsive design (mobile vs desktop layouts)
+- Accessibility (ARIA labels, keyboard navigation)
+
+✅ **Example E2E Assertions:**
+```typescript
+// GOOD: Testing UI state
+await expect(aclToggle).toBeChecked();
+await expect(statusBadge).toHaveText('Active');
+await expect(page).toHaveURL('/proxy-hosts');
+
+// GOOD: Testing API responses in management interface
+const response = await request.post('/api/v1/proxy-hosts', { data: hostConfig });
+expect(response.ok()).toBeTruthy();
+```
+
+#### What E2E Tests should NOT Cover
+
+❌ **Middleware Enforcement Behavior:**
+- Rate limiting blocking requests (429 responses)
+- ACL denying access based on IP rules (403 responses)
+- WAF blocking malicious payloads (SQL injection, XSS)
+- CrowdSec IP bans
+
+❌ **Example Wrong E2E Assertions:**
+```typescript
+// BAD: Testing middleware behavior (rate limiting)
+for (let i = 0; i < 6; i++) {
+  await request.post('/api/v1/emergency/reset');
+}
+expect(response.status()).toBe(429); // ❌ This tests Caddy middleware
+
+// BAD: Testing WAF blocking
+await request.post('/api/v1/data', { data: "'; DROP TABLE users--" });
+expect(response.status()).toBe(403); // ❌ This tests Coraza WAF
+```
+
+#### Integration Tests for Middleware
+
+Middleware enforcement is verified by **integration tests** in `backend/integration/`:
+
+- `cerberus_integration_test.go` - Overall security suite behavior
+- `coraza_integration_test.go` - WAF blocking (SQL injection, XSS)
+- `crowdsec_integration_test.go` - IP reputation and bans
+- `rate_limit_integration_test.go` - Request throttling
+
+These tests run in Docker Compose with full Caddy+Cerberus stack and are executed in separate CI workflows.
+
+#### When to Skip Tests
+
+Use `test.skip()` for tests that require middleware enforcement:
+
+```typescript
+test('should rate limit after 5 attempts', async ({ request }) => {
+  test.skip(
+    true,
+    'Rate limiting enforced via Cerberus middleware (port 80). Verified in integration tests (backend/integration/).'
+  );
+  // Test body...
+});
+```
+
+**Skip Reason Template:**

+# 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.

+
+# 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

+# 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)
+
+**Never skip any step. Use consistent terminology. Reduce ambiguity.**
+
+### **Phase 1: ANALYZE**
+
+**Objective:**

+    - Prioritize a **Proof-of-Concept (PoC)** or **Minimum Viable Product (MVP)**.
+    - Define clear success criteria for PoC/MVP.
+    - Build and validate PoC/MVP first, then expand plan incrementally.
+    - Document PoC/MVP goals, execution, and validation results.
+  - **Low Confidence (<66%)**
+    - Dedicate first phase to research and knowledge-building.
+    - Use semantic search and analyze similar implementations.
+    - Synthesize findings into a research document.
+    - Re-run ANALYZE phase after research.
+    - Escalate only if confidence remains low.
+
+- [ ] **Document technical design in `design.md`:**
+  - **Architecture:** High-level overview of components and interactions.
+  - **Data Flow:** Diagrams and descriptions.
+  - **Interfaces:** API contracts, schemas, public-facing function signatures.

+      - Document resolution order, justification, and verification.
+- [ ] Follow conventions.
+      - Document adherence and any deviations with a Decision Record.
+- [ ] Add meaningful comments.
+      - Focus on intent ("why"), not mechanics ("what").
+- [ ] Create files as planned.
+      - Document file creation log.
+- [ ] Update task status in real time.
+
+**Critical Constraint:**
+
+- **Do not merge or deploy code until all implementation steps are documented and tested.**
+
+### **Phase 4: VALIDATE**
+
+**Objective:**
+
+- Verify that implementation meets all requirements and quality standards.
+
+**Checklist:**
+
+- [ ] Execute automated tests.
+      - Document outputs, logs, and coverage reports.
+      - For failures, document root cause analysis and remediation.
+- [ ] Perform manual verification if necessary.
+      - Document procedures, checklists, and results.

+      - Document path analysis and runtime behavior.
+
+**Critical Constraint:**
+
+- **Do not proceed until all validation steps are complete and all issues are resolved.**
+
+### **Phase 5: REFLECT**
+
+**Objective:**
+
+- Improve codebase, update documentation, and analyze performance.
+
+**Checklist:**
+
+- [ ] Refactor for maintainability.
+      - Document decisions, before/after comparisons, and impact.
+- [ ] Update all project documentation.
+      - Ensure all READMEs, diagrams, and comments are current.
+- [ ] Identify potential improvements.
+      - Document backlog with prioritization.
+- [ ] Validate success criteria.
+      - Document final verification matrix.
+- [ ] Perform meta-analysis.
+      - Reflect on efficiency, tool usage, and protocol adherence.
+- [ ] Auto-create technical debt issues.
+      - Document inventory and remediation plans.
+
+**Critical Constraint:**
+
+- **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.
+      - Use **Compressed Decision Record** format.
+- [ ] Prepare pull request (if applicable):
+    1. Executive summary.
+    2. Changelog from **Streamlined Action Log**.
+    3. Links to validation artifacts and Decision Records.
+    4. Links to final `requirements.md`, `design.md`, and `tasks.md`.
+- [ ] Finalize workspace.
+      - Archive intermediate files, logs, and temporary artifacts to `.agent_work/`.
+- [ ] Continue to next task.
+      - 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

+
+# 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
 
+## 0. E2E Verification First (Playwright)
+
+**MANDATORY**: Before running unit tests, verify the application UI/UX functions correctly end-to-end.
+
+### 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)**
+
+**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)
+npx playwright test --project=chromium
+
+# With explicit base URL
+PLAYWRIGHT_BASE_URL=http://localhost:8080 npx playwright test --project=chromium
+```
+
+### 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.
@@ -16,3 +115,87 @@ description: 'Strict protocols for test execution, debugging, and coverage valid
 ## 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 Gate (Codecov):** If production code is modified, Codecov **patch coverage must be 100%** for the modified lines. Do not relax thresholds; add targeted tests.
+* **Patch Triage Requirement:** Plans must include the exact missing/partial patch line ranges copied from Codecov’s **Patch** view.
+## 4. GORM Security Validation (Manual Stage)
+
+**Requirement:** All backend changes involving GORM models or database interactions must pass the GORM Security Scanner.
+
+### When to Run
+
+* **Before Committing:** When modifying GORM models (files in `backend/internal/models/`)
+* **Before Opening PR:** Verify no security issues introduced
+* **After Code Review:** If model-related changes were requested
+* **Definition of Done:** Scanner must pass with zero CRITICAL/HIGH issues
+
+### 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)
+- **QA Report:** [docs/reports/gorm_scanner_qa_report.md](../docs/reports/gorm_scanner_qa_report.md)

+# Update Documentation on Code Change
+
+## Overview
+
+Ensure documentation stays synchronized with code changes by automatically detecting when README.md,
+API documentation, configuration guides, and other documentation files need updates based on code
+modifications.
+
+## 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
+
+## Output Format
+
+Structure your response as follows:
+
+```markdown

+- **DO** follow existing code standards in the repository (TypeScript, React, Go conventions)
+- **DO** filter framework internals from stack traces to focus on application code
+- **DO** consider both frontend and backend when investigating network errors
+
+## Error-Specific Handling
+
+### JavaScript Runtime Errors
+- Focus on type safety and null checks
+- Look for incorrect assumptions about data shapes
+- Check async/await and Promise handling
+
+### React Errors
+- Examine component lifecycle and hook dependencies
+- Check for stale closures in useEffect/useCallback
+- Verify prop types and default values
+- Look for missing keys in lists
+
+### Network Errors
+- Trace the full request path: frontend → backend → response
+- Check authentication/authorization middleware
+- Verify CORS configuration
+- Examine request/response payload shapes
+
+### Console Warnings
+- Assess severity (blocking vs. informational)
+- Prioritize deprecation warnings for future compatibility
+- Address React key warnings and dependency array warnings

+# 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

+# 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;
+```
+

+
+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

+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
+

+# Suggest Awesome GitHub Copilot Custom Agents
+
+Analyze current repository context and suggest relevant Custom Agents files from the [GitHub awesome-copilot repository](https://github.com/github/awesome-copilot/blob/main/docs/README.agents.md) that are not already available in this repository. Custom Agent files are located in the [agents](https://github.com/github/awesome-copilot/tree/main/agents) folder of the awesome-copilot repository.
+
+## Process
+
+1. **Fetch Available Custom Agents**: Extract Custom Agents list and descriptions from [awesome-copilot README.agents.md](https://github.com/github/awesome-copilot/blob/main/docs/README.agents.md). Must use `fetch` tool.
+2. **Scan Local Custom Agents**: Discover existing custom agent files in `.github/agents/` folder
+3. **Extract Descriptions**: Read front matter from local custom agent files to get descriptions
+4. **Analyze Context**: Review chat history, repository files, and current project needs
+5. **Compare Existing**: Check against custom agents already available in this repository
+6. **Match Relevance**: Compare available custom agents against identified patterns and requirements
+7. **Present Options**: Display relevant custom agents with descriptions, rationale, and availability status
+8. **Validate**: Ensure suggested agents would add value not already covered by existing agents
+9. **Output**: Provide structured table with suggestions, descriptions, and links to both awesome-copilot custom agents and similar local custom agents
+   **AWAIT** user request to proceed with installation of specific custom agents. DO NOT INSTALL UNLESS DIRECTED TO DO SO.
+10. **Download Assets**: For requested agents, automatically download and install individual agents to `.github/agents/` folder. Do NOT adjust content of the files. Use `#todos` tool to track progress. Prioritize use of `#fetch` tool to download assets, but may use `curl` using `#runInTerminal` tool to ensure all content is retrieved.

+...
+```
+
+## 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
+```
+

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

+# Docker: Rebuild E2E Environment
+
+## Overview
+
+Rebuilds the Charon Docker image and restarts the Playwright E2E testing environment with fresh code. This skill handles the complete lifecycle: stopping existing containers, optionally cleaning volumes, rebuilding the image, and starting fresh containers with health check verification.
+
+**Use this skill when:**
+- You've made code changes and need to test them in E2E tests
+- E2E tests are failing due to stale container state
+- You need a clean slate for debugging
+- The container is in an inconsistent state
+
+## Prerequisites
+
+- Docker Engine installed and running
+- Docker Compose V2 installed
+- Dockerfile in repository root
+  - `.docker/compose/docker-compose.playwright-ci.yml` file (used in CI)
+- Network access for pulling base images (if needed)
+- Sufficient disk space for image rebuild
+
+## Usage
+
+### Basic Usage
+
+Rebuild image and restart E2E container:
+
+```bash
+.github/skills/scripts/skill-runner.sh docker-rebuild-e2e
+```
+
+### Force Rebuild (No Cache)
+
+Rebuild from scratch without Docker cache:
+
+```bash
+.github/skills/scripts/skill-runner.sh docker-rebuild-e2e --no-cache
+```
+
+### Clean Rebuild
+
+Remove test volumes and rebuild with fresh state:
+
+```bash
+.github/skills/scripts/skill-runner.sh docker-rebuild-e2e --clean
+```
+
+### With Security Testing Services
+
+Enable CrowdSec for security testing:
+
+```bash
+.github/skills/scripts/skill-runner.sh docker-rebuild-e2e --profile=security-tests
+```
+
+### With Notification Testing Services
+
+Enable MailHog for email testing:
+
+```bash
+.github/skills/scripts/skill-runner.sh docker-rebuild-e2e --profile=notification-tests
+```
+
+### Full Clean Rebuild with All Services
+
+```bash
+.github/skills/scripts/skill-runner.sh docker-rebuild-e2e --no-cache --clean --profile=security-tests
+```
+
+## Parameters
+
+| Parameter | Type | Required | Default | Description |
+|-----------|------|----------|---------|-------------|
+| no-cache  | boolean | No | false | Force rebuild without Docker cache |
+| clean     | boolean | No | false | Remove test volumes for fresh state |
+| profile   | string | No | "" | Docker Compose profile to enable |
+
+## Environment Variables
+
+| Variable | Required | Default | Description |
+|----------|----------|---------|-------------|
+| DOCKER_NO_CACHE | No | false | Force rebuild without cache |
+| SKIP_VOLUME_CLEANUP | No | false | Preserve test data volumes |
+
+## What This Skill Does
+
+1. **Stop Existing Containers**: Gracefully stops any running Playwright containers
+2. **Clean Volumes** (if `--clean`): Removes test data volumes for fresh state
+3. **Rebuild Image**: Builds `charon:local` image from Dockerfile
+4. **Start Containers**: Starts the Playwright compose environment
+5. **Wait for Health**: Verifies container health before returning
+6. **Report Status**: Outputs container status and connection info
+
+## Docker Compose Configuration
+
+This skill uses `.docker/compose/docker-compose.playwright-ci.yml` which includes:
+
+- **charon-app**: Main application container on port 8080
+- **crowdsec** (profile: security-tests): Security bouncer for WAF testing
+- **mailhog** (profile: notification-tests): Email testing service
+
+### Volumes Created
+
+| Volume | Purpose |
+|--------|---------|
+| playwright_data | Application data and SQLite database |
+| playwright_caddy_data | Caddy server data |
+| playwright_caddy_config | Caddy configuration |
+| playwright_crowdsec_data | CrowdSec data (if enabled) |
+| playwright_crowdsec_config | CrowdSec config (if enabled) |
+
+## Examples
+
+### Example 1: Quick Rebuild After Code Change
+
+```bash
+# Rebuild and restart after making backend changes
+.github/skills/scripts/skill-runner.sh docker-rebuild-e2e
+
+# Run E2E tests
+.github/skills/scripts/skill-runner.sh test-e2e-playwright
+```
+
+### Example 2: Debug Failing Tests with Clean State
+
+```bash
+# Complete clean rebuild
+.github/skills/scripts/skill-runner.sh docker-rebuild-e2e --clean --no-cache
+
+# Run specific test in debug mode
+.github/skills/scripts/skill-runner.sh test-e2e-playwright-debug --grep="failing-test"
+```
+
+### Example 3: Test Security Features
+
+```bash
+# Start with CrowdSec enabled
+.github/skills/scripts/skill-runner.sh docker-rebuild-e2e --profile=security-tests
+
+# Run security-related E2E tests
+.github/skills/scripts/skill-runner.sh test-e2e-playwright --grep="security"
+```
+
+## Health Check Verification
+
+After starting, the skill waits for the health check to pass:
+
+```bash
+# Health endpoint checked
+curl -sf http://localhost:8080/api/v1/health
+```
+
+The skill will:
+- Wait up to 60 seconds for container to be healthy
+- Check every 5 seconds
+- Report final health status
+- Exit with error if health check fails
+
+## Error Handling
+
+### Common Issues
+
+#### Docker Build Failed
+```
+Error: docker build failed
+```
+**Solution**: Check Dockerfile syntax, ensure all COPY sources exist
+
+#### Port Already in Use
+```
+Error: bind: address already in use
+```
+**Solution**: Stop conflicting services on port 8080
+
+#### Health Check Timeout
+```
+Error: Container did not become healthy in 60s
+```
+**Solution**: Check container logs with `docker logs charon-playwright`
+
+#### Volume Permission Issues
+```
+Error: permission denied
+```
+**Solution**: Run with `--clean` to recreate volumes with proper permissions
+
+## Verifying the Environment
+
+After the skill completes, verify the environment:
+
+```bash
+# Check container status
+docker ps --filter "name=charon-playwright"
+
+# Check logs
+docker logs charon-playwright --tail 50
+
+# Test health endpoint
+curl http://localhost:8080/api/v1/health
+
+# Check database state
+docker exec charon-playwright sqlite3 /app/data/charon.db ".tables"
+```

+## Key File Locations
+
+| File | Purpose |
+|------|---------|
+| `Dockerfile` | Main application Dockerfile |
+| `.docker/compose/docker-compose.playwright-ci.yml` | CI E2E test compose config |
+| `.docker/compose/docker-compose.playwright-local.yml` | Local E2E test compose config |
+| `playwright.config.js` | Playwright test configuration |
+| `tests/` | E2E test files |
+| `playwright/.auth/user.json` | Stored authentication state |
+
+## Notes
+
+- **Build Time**: Full rebuild takes 2-5 minutes depending on cache
+- **Disk Space**: Image is ~500MB, volumes add ~100MB
+- **Network**: Base images may need to be pulled on first run
+- **Idempotent**: Safe to run multiple times
+- **CI/CD Safe**: Designed for use in automated pipelines

+# Security Scan CodeQL
+
+## Overview
+
+Executes GitHub CodeQL static analysis security testing (SAST) for Go and JavaScript/TypeScript code. Uses the **security-and-quality** query suite to match GitHub Actions CI configuration exactly.
+
+This skill ensures local development catches the same security issues that CI would detect, preventing CI failures due to security findings.
+
+## Prerequisites
+
+- CodeQL CLI 2.17.0 or higher installed
+- Query packs: `codeql/go-queries`, `codeql/javascript-queries`
+- Sufficient disk space for CodeQL databases (~500MB per language)
+
+## Usage
+
+### Basic Usage
+
+Scan all languages with summary output:
+
+```bash
+cd /path/to/charon
+.github/skills/scripts/skill-runner.sh security-scan-codeql
+```
+
+### Scan Specific Language
+
+Scan only Go code:
+
+```bash
+.github/skills/scripts/skill-runner.sh security-scan-codeql go
+```
+
+Scan only JavaScript/TypeScript code:
+
+```bash
+.github/skills/scripts/skill-runner.sh security-scan-codeql javascript
+```
+
+### Full SARIF Output
+
+Get detailed SARIF output for integration with tools:
+
+```bash
+.github/skills/scripts/skill-runner.sh security-scan-codeql all sarif
+```
+
+### Text Output
+
+Get text-formatted detailed findings:
+
+```bash
+.github/skills/scripts/skill-runner.sh security-scan-codeql all text
+```
+
+## Parameters
+
+| Parameter | Type | Required | Default | Description |
+|-----------|------|----------|---------|-------------|
+| language  | string | No     | all     | Language to scan (go, javascript, all) |
+| format    | string | No     | summary | Output format (sarif, text, summary) |
+
+## Environment Variables
+
+| Variable | Required | Default | Description |
+|----------|----------|---------|-------------|
+| CODEQL_THREADS | No | 0 | Analysis threads (0 = auto-detect) |
+| CODEQL_FAIL_ON_ERROR | No | true | Fail on HIGH/CRITICAL findings |
+
+## Query Suite
+
+This skill uses the **security-and-quality** suite to match CI:
+
+| Language | Suite | Queries | Coverage |
+|----------|-------|---------|----------|
+| Go | go-security-and-quality.qls | 61 | Security + quality issues |
+| JavaScript | javascript-security-and-quality.qls | 204 | Security + quality issues |
+
+**Note:** This matches GitHub Actions CodeQL default configuration exactly.
+
+## Outputs
+
+- **SARIF Files**:
+  - `codeql-results-go.sarif` - Go findings
+  - `codeql-results-js.sarif` - JavaScript/TypeScript findings
+- **Databases**:
+  - `codeql-db-go/` - Go CodeQL database
+  - `codeql-db-js/` - JavaScript CodeQL database
+- **Exit Codes**:
+  - 0: No HIGH/CRITICAL findings
+  - 1: HIGH/CRITICAL findings detected
+  - 2: Scanner error
+
+## Security Categories
+
+### CWE Coverage
+
+| Category | Description | Languages |
+|----------|-------------|-----------|
+| CWE-079 | Cross-Site Scripting (XSS) | JS |
+| CWE-089 | SQL Injection | Go, JS |
+| CWE-117 | Log Injection | Go |
+| CWE-200 | Information Exposure | Go, JS |
+| CWE-312 | Cleartext Storage | Go, JS |
+| CWE-327 | Weak Cryptography | Go, JS |

+
+## Examples
+
+### Example 1: Full Scan (Default)
+
+```bash
+# Scan all languages, show summary
+.github/skills/scripts/skill-runner.sh security-scan-codeql
+```
+
+Output:
+```
+[STEP] CODEQL: Scanning Go code...
+[INFO] Creating database for backend/
+[INFO] Analyzing with security-and-quality suite (61 queries)
+[INFO] Found: 0 errors, 5 warnings, 3 notes
+[STEP] CODEQL: Scanning JavaScript code...
+[INFO] Creating database for frontend/
+[INFO] Analyzing with security-and-quality suite (204 queries)
+[INFO] Found: 0 errors, 2 warnings, 8 notes
+[SUCCESS] CodeQL scan complete - no HIGH/CRITICAL issues
+```
+
+### Example 2: Go Only with Text Output
+
+```bash
+# Detailed text output for Go findings
+.github/skills/scripts/skill-runner.sh security-scan-codeql go text
+```
+
+### Example 3: CI/CD Pipeline Integration
+
+```yaml
+# GitHub Actions example (already integrated in codeql.yml)
+- name: Run CodeQL Security Scan
+  run: .github/skills/scripts/skill-runner.sh security-scan-codeql all summary
+  continue-on-error: false
+```
+
+### Example 4: Pre-Commit Integration
+
+```bash
+# Already available via pre-commit
+pre-commit run codeql-go-scan --all-files
+pre-commit run codeql-js-scan --all-files
+pre-commit run codeql-check-findings --all-files
+```
+
+## Error Handling
+
+### Common Issues
+
+**CodeQL version too old**:
+```bash
+Error: Extensible predicate API mismatch
+Solution: Upgrade CodeQL CLI: gh codeql set-version latest
+```
+
+**Query pack not found**:
+```bash
+Error: Could not resolve pack codeql/go-queries
+Solution: codeql pack download codeql/go-queries codeql/javascript-queries
+```
+
+**Database creation failed**:
+```bash
+Error: No source files found
+Solution: Verify source-root points to correct directory
+```
+
+## Exit Codes
+
+- **0**: No HIGH/CRITICAL (error-level) findings
+- **1**: HIGH/CRITICAL findings detected (blocks CI)
+- **2**: Scanner error or invalid arguments

+
+## CI Alignment
+
+This skill is specifically designed to match GitHub Actions CodeQL workflow:
+
+| Parameter | Local | CI | Aligned |
+|-----------|-------|-----|---------|
+| Query Suite | security-and-quality | security-and-quality | ✅ |
+| Go Queries | 61 | 61 | ✅ |
+| JS Queries | 204 | 204 | ✅ |
+| Threading | auto | auto | ✅ |
+| Baseline Info | enabled | enabled | ✅ |
+
+## Viewing Results
+
+### VS Code SARIF Viewer (Recommended)
+
+1. Install extension: `MS-SarifVSCode.sarif-viewer`
+2. Open `codeql-results-go.sarif` or `codeql-results-js.sarif`
+3. Navigate findings with inline annotations
+
+### Command Line (jq)
+
+```bash
+# Count findings
+jq '.runs[].results | length' codeql-results-go.sarif
+
+# List findings
+jq -r '.runs[].results[] | "\(.level): \(.message.text)"' codeql-results-go.sarif
+```
+
+### GitHub Security Tab
+
+SARIF files are automatically uploaded to GitHub Security tab in CI.
+
+## Performance
+
+| Language | Database Creation | Analysis | Total |
+|----------|------------------|----------|-------|
+| Go | ~30s | ~30s | ~60s |
+| JavaScript | ~45s | ~45s | ~90s |
+| All | ~75s | ~75s | ~150s |
+
+**Note:** First run downloads query packs; subsequent runs are faster.
+
+## Notes
+
+- Requires CodeQL CLI 2.17.0+ (use `gh codeql set-version latest` to upgrade)
+- Databases are regenerated each run (not cached)
+- SARIF files are gitignored (see `.gitignore`)
+- Query results may vary between CodeQL versions
+- Use `.codeql/` directory for custom queries or suppressions

+# Security: Scan Docker Image (Local)
+
+## Overview
+
+**CRITICAL GAP ADDRESSED**: This skill closes a critical security gap discovered in the Charon project's local development workflow. While the existing Trivy filesystem scanner catches some issues, it misses vulnerabilities that only exist in the actual built Docker image, including:
+
+- **Alpine package vulnerabilities** in the base image
+- **Compiled binary vulnerabilities** in Go dependencies
+- **Embedded dependencies** that only exist post-build
+- **Multi-stage build artifacts** not present in source
+- **Runtime dependencies** added during Docker build
+
+This skill replicates the **exact CI supply chain verification process** used in the `supply-chain-pr.yml` workflow, ensuring local scans match CI scans precisely. This prevents the "works locally but fails in CI" scenario and catches image-only vulnerabilities before they reach production.
+
+## Key Differences from Trivy Filesystem Scan
+
+| Aspect | Trivy (Filesystem) | This Skill (Image Scan) |
+|--------|-------------------|------------------------|
+| **Scan Target** | Source code + dependencies | Built Docker image |
+| **Alpine Packages** | ❌ Not detected | ✅ Detected |
+| **Compiled Binaries** | ❌ Not detected | ✅ Detected |
+| **Build Artifacts** | ❌ Not detected | ✅ Detected |
+| **CI Alignment** | ⚠️ Different results | ✅ Exact match |
+| **Supply Chain** | Partial coverage | Full coverage |
+
+## Features
+
+- **Exact CI Matching**: Uses same Syft and Grype versions as supply-chain-pr.yml
+- **Image-Based Scanning**: Scans the actual Docker image, not just filesystem
+- **SBOM Generation**: Creates CycloneDX JSON SBOM from the built image
+- **Severity-Based Failures**: Fails on Critical/High severity by default
+- **Detailed Reporting**: Counts vulnerabilities by severity
+- **Build Integration**: Builds the Docker image first, ensuring latest code
+- **Idempotent Scans**: Can be run repeatedly with consistent results
+
+## Prerequisites
+
+- Docker 24.0 or higher installed and running
+- Syft 1.17.0 or higher (auto-checked, installation instructions provided)
+- Grype 0.85.0 or higher (auto-checked, installation instructions provided)
+- jq 1.6 or higher (for JSON processing)
+- Internet connection (for vulnerability database updates)
+- Sufficient disk space for Docker image build (~2GB recommended)

+
+### Example 3: CI/CD Pipeline Integration
+
+```yaml
+# .github/workflows/local-verify.yml (example)
+- name: Scan Docker Image Locally
+  run: .github/skills/scripts/skill-runner.sh security-scan-docker-image
+  continue-on-error: false
+
+- name: Upload SBOM Artifact
+  uses: actions/upload-artifact@v4
+  with:
+    name: local-sbom
+    path: sbom.cyclonedx.json
+```
+
+### Example 4: Pre-Commit Hook Integration
+
+```bash
+# .git/hooks/pre-push
+#!/bin/bash
+echo "Running local Docker image security scan..."
+if ! .github/skills/scripts/skill-runner.sh security-scan-docker-image; then
+    echo "❌ Security scan failed - please fix vulnerabilities before pushing"
+    exit 1
+fi
+```
+
+## How It Works
+
+### Build Phase
+
+1. **Docker Build**: Builds the Docker image using the project's Dockerfile
+   - Uses multi-stage build for frontend and backend
+   - Applies build args: VERSION, BUILD_DATE, VCS_REF
+   - Tags with specified image tag (default: charon:local)
+
+### SBOM Generation Phase
+
+2. **Image Analysis**: Syft analyzes the built Docker image (not filesystem)
+   - Scans all layers in the final image
+   - Detects Alpine packages, Go modules, npm packages
+   - Identifies compiled binaries and their dependencies
+   - Catalogs runtime dependencies added during build
+
+3. **SBOM Creation**: Generates CycloneDX JSON SBOM
+   - Industry-standard format for supply chain visibility
+   - Contains full package inventory with versions
+   - Includes checksums and license information
+
+### Vulnerability Scanning Phase
+
+4. **Database Update**: Grype updates its vulnerability database
+   - Fetches latest CVE information
+   - Ensures scan uses current vulnerability data
+
+5. **Image Scan**: Grype scans the SBOM against vulnerability database
+   - Matches packages against known CVEs
+   - Calculates CVSS scores for each vulnerability
+   - Generates SARIF output for GitHub Security
+
+6. **Severity Analysis**: Counts vulnerabilities by severity
+   - Critical: CVSS 9.0-10.0
+   - High: CVSS 7.0-8.9
+   - Medium: CVSS 4.0-6.9
+   - Low: CVSS 0.1-3.9
+
+### Reporting Phase
+
+7. **Results Summary**: Displays vulnerability counts and details
+8. **Exit Code**: Returns appropriate exit code based on severity findings
+
+## Vulnerability Severity Thresholds
+
+**Project Standards (Matches CI)**:
+
+| Severity | CVSS Range | Action | Exit Code |
+|----------|-----------|--------|-----------|
+| 🔴 **CRITICAL** | 9.0-10.0 | **MUST FIX** - Blocks commit/push | 1 |
+| 🟠 **HIGH** | 7.0-8.9 | **SHOULD FIX** - Blocks commit/push | 1 |
+| 🟡 **MEDIUM** | 4.0-6.9 | Fix in next release (logged) | 0 |
+| 🟢 **LOW** | 0.1-3.9 | Optional, fix as time permits | 0 |
+
+## Error Handling
+
+### Common Issues
+
+**Docker not running**:
+```bash
+[ERROR] Docker daemon is not running
+Solution: Start Docker Desktop or Docker service
+```
+
+**Syft not installed**:
+```bash
+[ERROR] Syft not found - install from: https://github.com/anchore/syft
+Solution: Install Syft v1.17.0 using installation instructions above
+```
+
+**Grype not installed**:
+```bash
+[ERROR] Grype not found - install from: https://github.com/anchore/grype
+Solution: Install Grype v0.107.0 using installation instructions above
+```
+
+**Build failure**:
+```bash
+[ERROR] Docker build failed with exit code 1
+Solution: Check Dockerfile syntax and dependency availability
+```
+
+**Network timeout (vulnerability scan)**:
+```bash
+[WARNING] Failed to update Grype vulnerability database
+Solution: Check internet connection or retry later
+```
+
+**Disk space insufficient**:
+```bash
+[ERROR] No space left on device
+Solution: Clean up Docker images and containers: docker system prune -a
+```
+
+## Integration with Definition of Done
+
+This skill is **MANDATORY** in the Management agent's Definition of Done checklist:
+
+### When to Run
+
+- ✅ **Before every commit** that changes application code
+- ✅ **After dependency updates** (Go modules, npm packages)
+- ✅ **Before creating a Pull Request**
+- ✅ **After Dockerfile modifications**
+- ✅ **Before release/tag creation**
+
+### QA_Security Requirements
+
+The QA_Security agent **MUST**:
+
+1. Run this skill after running Trivy filesystem scan
+2. Verify that both scans pass with zero Critical/High issues
+3. Document any differences between filesystem and image scans
+4. Block approval if image scan reveals additional vulnerabilities
+5. Report findings in the QA report at `docs/reports/qa_report.md`
+
+### Why This is Critical
+
+**Image-only vulnerabilities** can exist even when filesystem scans pass:
+
+- Alpine base image CVEs (e.g., musl, busybox, apk-tools)
+- Compiled Go binary vulnerabilities (e.g., stdlib CVEs)
+- Caddy plugin vulnerabilities added during build
+- Multi-stage build artifacts with known issues
+
+**Without this scan**, these vulnerabilities reach production undetected.
+
+## Comparison with CI Supply Chain Workflow
+
+This skill **exactly replicates** the supply-chain-pr.yml workflow:
+
+| Step | CI Workflow | This Skill | Match |
+|------|------------|------------|-------|
+| Build Image | ✅ Docker build | ✅ Docker build | ✅ |
+| Load Image | ✅ Load from artifact | ✅ Use built image | ✅ |
+| Syft Version | v1.17.0 | v1.17.0 | ✅ |
+| Grype Version | v0.107.0 | v0.107.0 | ✅ |
+| SBOM Format | CycloneDX JSON | CycloneDX JSON | ✅ |
+| Scan Target | Docker image | Docker image | ✅ |
+| Severity Counts | Critical/High/Medium/Low | Critical/High/Medium/Low | ✅ |
+| Exit on Critical/High | Yes | Yes | ✅ |
+| SARIF Output | Yes | Yes | ✅ |
+
+**Guarantee**: If this skill passes locally, the CI supply chain workflow will pass (assuming same code/dependencies).

+## Workflow Integration
+
+### Recommended Execution Order
+
+1. **Trivy Filesystem Scan** - Fast, catches obvious issues
+2. **Docker Image Scan (this skill)** - Comprehensive, catches image-only issues
+3. **CodeQL Scans** - Static analysis for code quality
+4. **SBOM Verification** - Supply chain drift detection
+
+### Combined DoD Checklist
+
+```bash
+# 1. Filesystem scan (fast)
+.github/skills/scripts/skill-runner.sh security-scan-trivy
+
+# 2. Image scan (comprehensive) - THIS SKILL
+.github/skills/scripts/skill-runner.sh security-scan-docker-image
+
+# 3. Code analysis
+.github/skills/scripts/skill-runner.sh security-scan-codeql
+
+# 4. Go vulnerabilities
+.github/skills/scripts/skill-runner.sh security-scan-go-vuln
+```
+
+## Performance Considerations
+
+### Execution Time
+
+- **Docker Build**: 2-5 minutes (cached), 5-10 minutes (no-cache)
+- **SBOM Generation**: 30-60 seconds
+- **Vulnerability Scan**: 30-60 seconds
+- **Total**: ~3-7 minutes (typical), ~6-12 minutes (no-cache)
+
+### Optimization Tips
+
+1. **Use Docker layer caching** (default) for faster builds
+2. **Run after code changes only** (not needed for doc-only changes)
+3. **Parallelize with other scans** (Trivy, CodeQL) for efficiency
+4. **Cache vulnerability database** (Grype auto-caches)
+
+## Security Considerations
+
+- SBOM files contain full package inventory (treat as sensitive)
+- Vulnerability results may contain CVE details (secure storage)
+- Never commit scan results with credentials/tokens
+- Review all Critical/High findings before production deployment
+- Keep Syft and Grype updated to latest versions
+
+## Troubleshooting
+
+### Build Always Fails
+
+Check Dockerfile syntax and build context:
+
+```bash
+# Test build manually
+docker build -t charon:test .
+
+# Check build args
+docker build --build-arg VERSION=test -t charon:test .
+```
+
+### Scan Detects False Positives
+
+Create `.grype.yaml` in project root to suppress known false positives:
+
+```yaml
+ignore:
+  - vulnerability: CVE-2024-12345
+    fix-state: wont-fix
+```
+
+### Different Results Than CI
+
+Verify versions match:
+
+```bash
+syft version  # Should be v1.17.0
+grype version # Should be v0.107.0
+```
+
+Update if needed:
+
+```bash
+# Reinstall specific versions
+curl -sSfL https://raw.githubusercontent.com/anchore/syft/main/install.sh | sh -s -- -b /usr/local/bin v1.17.0
+curl -sSfL https://raw.githubusercontent.com/anchore/grype/main/install.sh | sh -s -- -b /usr/local/bin v0.107.0
+```
+
+## Notes
+
+- This skill is **not idempotent** due to Docker build step
+- Scan results may vary as vulnerability database updates
+- Some vulnerabilities may have no fix available yet
+- Alpine base image updates may resolve multiple CVEs
+- Go stdlib updates may resolve compiled binary CVEs
+- Network access required for database updates
+- Recommended to run before each commit/push
+- Complements but does not replace Trivy filesystem scan

+# GORM Security Scanner
+
+## Overview
+
+The GORM Security Scanner is a **static analysis tool** that automatically detects GORM security issues and common mistakes in Go codebases. It focuses on preventing ID leak vulnerabilities (IDOR attacks), detecting exposed secrets, and enforcing GORM best practices.
+
+This skill is essential for maintaining secure database models and preventing information disclosure vulnerabilities before they reach production.
+
+## When to Use This Skill
+
+Use this skill when:
+- ✅ Creating or modifying GORM database models
+- ✅ Reviewing code for security issues before commit
+- ✅ Validating API response DTOs for ID exposure
+- ✅ Checking for exposed API keys, tokens, or passwords
+- ✅ Auditing codebase for GORM best practices compliance
+- ✅ Running pre-commit security checks
+- ✅ Performing security audits in CI/CD pipelines
+
+## Prerequisites
+
+- Bash 4.0 or higher
+- GNU grep (standard on Linux/macOS)
+- Read permissions for backend directory
+- Project must have Go code with GORM models
+
+## Security Issues Detected
+
+### 🔴 CRITICAL: Numeric ID Exposure
+
+**What:** GORM models with `uint`/`int` primary keys that have `json:"id"` tags
+
+**Risk:** Information disclosure, IDOR vulnerability, database enumeration
+
+**Example:**
+```go
+// ❌ BAD: Internal database ID exposed
+type User struct {
+    ID   uint   `json:"id" gorm:"primaryKey"`  // CRITICAL ISSUE
+    UUID string `json:"uuid"`
+}
+
+// ✅ GOOD: ID hidden, UUID exposed
+type User struct {
+    ID   uint   `json:"-" gorm:"primaryKey"`
+    UUID string `json:"uuid" gorm:"uniqueIndex"`
+}
+```
+
+**Note:** String-based IDs are **allowed** (assumed to be UUIDs/opaque identifiers)
+
+### 🔴 CRITICAL: Exposed API Keys/Secrets
+
+**What:** Fields with sensitive names (APIKey, Secret, Token, Password) that have visible JSON tags
+
+**Risk:** Credential exposure, unauthorized access
+
+**Example:**
+```go
+// ❌ BAD: API key visible in responses
+type User struct {
+    APIKey string `json:"api_key"`  // CRITICAL ISSUE
+}
+
+// ✅ GOOD: API key hidden
+type User struct {
+    APIKey string `json:"-"`
+}
+```
+
+### 🟡 HIGH: Response DTO Embedding Models
+
+**What:** Response structs that embed GORM models, inheriting exposed ID fields
+
+**Risk:** Unintentional ID exposure through embedding
+
+**Example:**
+```go
+// ❌ BAD: Inherits exposed ID from models.ProxyHost
+type ProxyHostResponse struct {
+    models.ProxyHost  // HIGH ISSUE
+    Warnings []string `json:"warnings"`
+}
+
+// ✅ GOOD: Explicitly define fields

+```
+
+### 🔵 MEDIUM: Missing Primary Key Tag
+
+**What:** ID fields with GORM tags but missing `primaryKey` directive
+
+**Risk:** GORM may not recognize field as primary key, causing indexing issues
+
+### 🟢 INFO: Missing Foreign Key Index
+
+**What:** Foreign key fields (ending with ID) without index tags
+
+**Impact:** Query performance degradation
+
+**Suggestion:** Add `gorm:"index"` for better performance

+
+## Detection Patterns
+
+### Pattern 1: ID Leak Detection
+
+**Target:** GORM models with numeric IDs exposed in JSON
+
+**Detection Logic:**
+1. Find `type XXX struct` declarations
+2. Apply GORM model detection heuristics:
+   - File in `internal/models/` directory, OR
+   - Struct has 2+ fields with `gorm:` tags, OR
+   - Struct embeds `gorm.Model`
+3. Check for `ID` field with numeric type (`uint`, `int`, `int64`, etc.)
+4. Check for `json:"id"` tag (not `json:"-"`)
+5. Flag as **CRITICAL**
+
+**String ID Policy:** String-based IDs are **NOT flagged** (assumed to be UUIDs)
+
+### Pattern 2: DTO Embedding
+
+**Target:** Response/DTO structs that embed GORM models
+
+**Detection Logic:**
+1. Find structs with "Response" or "DTO" in name
+2. Look for embedded model types (from `models` package)
+3. Check if embedded model has exposed ID field
+4. Flag as **HIGH**
+
+### Pattern 3: Exposed Secrets
+
+**Target:** API keys, tokens, passwords, secrets with visible JSON tags
+
+**Detection Logic:**
+1. Find fields matching: `APIKey`, `Secret`, `Token`, `Password`, `Hash`
+2. Check if JSON tag is NOT `json:"-"`
+3. Flag as **CRITICAL**
+
+### Pattern 4: Missing Primary Key Tag
+
+**Target:** ID fields without `gorm:"primaryKey"`
+
+**Detection Logic:**
+1. Find ID fields with GORM tags
+2. Check if `primaryKey` directive is missing
+3. Flag as **MEDIUM**
+
+### Pattern 5: Missing Foreign Key Index
+
+**Target:** Foreign key fields without index tags
+
+**Detection Logic:**
+1. Find fields ending with `ID` or `Id`
+2. Check if GORM tag lacks `index` directive
+3. Flag as **INFO**
+
+### Pattern 6: Missing UUID Fields
+
+**Target:** Models with exposed IDs but no external identifier
+
+**Detection Logic:**
+1. Find models with exposed `json:"id"`
+2. Check if `UUID` field exists
+3. Flag as **HIGH** if missing
+
+## Suppression Mechanism
+
+Use inline comments to suppress false positives:
+
+### Comment Format
+
+```go
+// gorm-scanner:ignore [optional reason]
+```
+
+### Examples
+
+**External API Response:**
+```go
+// gorm-scanner:ignore External API response, not a GORM model
+type GitHubUser struct {
+    ID int `json:"id"`  // Won't be flagged
+}
+```
+
+**Legacy Code During Migration:**
+```go
+// gorm-scanner:ignore Legacy model, scheduled for refactor in #1234
+type OldModel struct {
+    ID uint `json:"id" gorm:"primaryKey"`
+}
+```
+
+**Internal Service (Never Serialized):**
+```go
+// gorm-scanner:ignore Internal service struct, never serialized to HTTP
+type InternalProcessorState struct {
+    ID uint `json:"id"`
+}
+```
+
+## GORM Model Detection Heuristics
+
+The scanner uses three heuristics to identify GORM models (prevents false positives):
+
+1. **Location-based:** File is in `internal/models/` directory
+2. **Tag-based:** Struct has 2+ fields with `gorm:` tags
+3. **Embedding-based:** Struct embeds `gorm.Model`
+
+**Non-GORM structs are ignored:**
+- Docker container info structs
+- External API response structs
+- WebSocket connection tracking
+- Manual challenge structs
+
+## Performance Metrics
+
+**Measured Performance:**
+- **Execution Time:** 2.1 seconds (average)
+- **Target:** <5 seconds per full scan
+- **Performance Rating:** ✅ **Excellent** (58% faster than requirement)
+- **Files Scanned:** 40 Go files
+- **Lines Processed:** 2,031 lines
+
+## Examples
+
+### Example 1: Development Workflow
+
+```bash
+# Before committing changes to GORM models
+.github/skills/scripts/skill-runner.sh security-scan-gorm
+
+# Save report for later review
+.github/skills/scripts/skill-runner.sh security-scan-gorm --report docs/reports/gorm-scan-$(date +%Y%m%d).txt
+
+# If issues found, fix them
+# Re-run to verify fixes
+```
+
+### Example 2: CI/CD Pipeline
+
+```yaml
+# GitHub Actions workflow
+- name: GORM Security Scanner
+  run: .github/skills/scripts/skill-runner.sh security-scan-gorm --check docs/reports/gorm-scan-ci.txt
+  continue-on-error: false
+
+- name: Upload GORM Scan Report
+  if: always()
+  uses: actions/upload-artifact@v4
+  with:
+    name: gorm-security-report
+    path: docs/reports/gorm-scan-ci.txt
+    retention-days: 30
+```
+
+### Example 3: Pre-commit Hook
+
+```bash
+# Manual invocation
+pre-commit run --hook-stage manual gorm-security-scan --all-files
+
+# After remediation, move to blocking stage
+# Edit .pre-commit-config.yaml:
+# stages: [commit]  # Change from [manual]
+```
+
+### Example 4: Verbose Mode for Debugging
+
+```bash
+# Enable debug output
+VERBOSE=1 ./scripts/scan-gorm-security.sh --report
+
+# Shows:
+# - File scanning progress
+# - GORM model detection decisions
+# - Suppression comment handling
+# - Pattern matching logic
+```
+
+## Error Handling
+
+### Common Issues
+
+**Scanner not found:**
+```bash
+Error: ./scripts/scan-gorm-security.sh not found
+Solution: Ensure script has execute permissions: chmod +x scripts/scan-gorm-security.sh
+```
+
+**Permission denied:**
+```bash
+Error: Permission denied: backend/internal/models/user.go
+Solution: Check file permissions and current user access
+```
+
+**No Go files found:**
+```bash
+Warning: No Go files found in backend/
+Solution: Verify you're running from project root
+```
+
+**False positive on valid code:**
+```bash
+Solution: Add suppression comment: // gorm-scanner:ignore [reason]
+```
+
+## Troubleshooting
+
+### Issue: Scanner reports false positives
+
+**Cause:** Non-GORM struct incorrectly flagged
+
+**Solution:**
+1. Add suppression comment with reason
+2. Verify struct doesn't match GORM heuristics
+3. Report as enhancement if pattern needs refinement
+
+### Issue: Scanner misses known issues
+
+**Cause:** Custom MarshalJSON implementation or XML/YAML tags
+
+**Solution:**
+1. Manual code review for custom marshaling
+2. Check for `xml:` or `yaml:` tags (not yet supported)
+3. See "Known Limitations" section
+
+### Issue: Scanner runs slowly
+
+**Cause:** Large codebase or slow filesystem
+
+**Solution:**
+1. Run on specific directory: `cd backend && ../scripts/scan-gorm-security.sh`
+2. Use incremental scanning in pre-commit (only changed files)
+3. Check filesystem performance
+
+## Known Limitations
+
+1. **Custom MarshalJSON Not Detected**
+   - Scanner can't detect ID leaks in custom JSON marshaling logic
+   - Mitigation: Manual code review
+
+2. **XML and YAML Tags Not Checked**
+   - Only `json:` tags are scanned currently
+   - Future: Pattern 7 (XML) and Pattern 8 (YAML)
+
+3. **Multi-line Tag Handling**
+   - Tags split across lines may not be detected
+   - Enforce single-line tags in style guide
+
+4. **Interface Implementations**
+   - Models returned through interfaces may bypass detection
+   - Future: Type-based analysis
+
+5. **Map Conversions and Reflection**
+   - Runtime conversions not analyzed
+   - Mitigation: Code review, runtime monitoring
+
+## Security Thresholds
+
+**Project Standards:**
+- **🔴 CRITICAL**: Must fix immediately (blocking)
+- **🟡 HIGH**: Should fix before PR merge (warning)
+- **🔵 MEDIUM**: Fix in current sprint (informational)
+- **🟢 INFO**: Optimize when convenient (suggestion)
+
+## Integration Points
+
+- **Pre-commit:** Manual stage (soft launch), move to commit stage after remediation
+- **VS Code:** Command Palette → "Lint: GORM Security Scan"
+- **CI/CD:** GitHub Actions quality-checks workflow
+- **Definition of Done:** Required check before task completion

+
+## Best Practices
+
+1. **Run Before Every Commit**: Catch issues early in development
+2. **Fix Critical Issues Immediately**: Don't ignore CRITICAL/HIGH findings
+3. **Document Suppressions**: Always explain why an issue is suppressed
+4. **Review Periodically**: Audit suppression comments quarterly
+5. **Integrate in CI**: Prevent regressions from reaching production
+6. **Use UUIDs for External IDs**: Never expose internal database IDs
+7. **Hide Sensitive Fields**: All API keys, tokens, passwords should have `json:"-"`
+8. **Save Reports for Audit**: Export scan results to `docs/reports/` for tracking and compliance
+9. **Track Progress**: Compare reports over time to verify issue remediation
+
+## Remediation Guidance
+
+### 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"`    // Exposed
+}
+
+// Update API clients to use UUID instead of ID
+```
+
+### Fix Exposed Secret
+
+```go
+// Before
+type User struct {
+    APIKey string `json:"api_key"`
+}
+
+// After
+type User struct {
+    APIKey string `json:"-"`  // Never expose credentials
+}
+```
+
+### Fix DTO Embedding
+
+```go
+// Before
+type ProxyHostResponse struct {
+    models.ProxyHost  // Inherits exposed ID
+    Warnings []string `json:"warnings"`
+}
+
+// After
+type ProxyHostResponse struct {
+    UUID        string   `json:"uuid"`        // Explicit fields only
+    Name        string   `json:"name"`
+    DomainNames string   `json:"domain_names"`
+    Warnings    []string `json:"warnings"`
+}
+```
+
+## Report Files
+
+**Recommended Locations:**
+- **Development:** `docs/reports/gorm-scan-YYYYMMDD.txt` (dated reports)
+- **CI/CD:** `docs/reports/gorm-scan-ci.txt` (uploaded as artifact)
+- **Pre-Release:** `docs/reports/gorm-scan-release.txt` (audit trail)
+
+**Report Format:**
+- Plain text with ANSI color codes (terminal-friendly)
+- Includes severity breakdown and summary metrics
+- Contains file:line references for all issues
+- Provides remediation guidance for each finding
+
+**Agent Usage:**
+AI agents can read saved reports instead of parsing terminal output:
+```bash
+# Generate report
+.github/skills/scripts/skill-runner.sh security-scan-gorm --report docs/reports/gorm-scan.txt
+
+# Agent reads report
+# File contains structured findings with severity, location, and fixes
+```

+# Security: Sign with Cosign
+
+Sign Docker images and files using Cosign (Sigstore) for supply chain security and artifact integrity verification.
+
+## Overview
+
+This skill signs Docker images and arbitrary files using Cosign, creating cryptographic signatures that can be verified by consumers. It supports both keyless signing (using GitHub OIDC tokens in CI/CD) and key-based signing (using local private keys for development).
+
+Signatures are stored in Rekor transparency log for public accountability and can be verified without sharing private keys.
+
+## Features
+
+- Sign Docker images (stored in registry)
+- Sign arbitrary files (binaries, archives, etc.)
+- Keyless signing with GitHub OIDC (CI/CD)
+- Key-based signing with local keys (development)
+- Automatic verification after signing
+- Rekor transparency log integration
+- Non-interactive mode for automation
+
+## Prerequisites
+
+- Cosign 2.4.0 or higher
+- Docker (for image signing)
+- GitHub account (for keyless signing with OIDC)
+- Or: Local key pair (for key-based signing)
+
+## Usage
+
+### Sign Docker Image (Keyless - CI/CD)
+
+In GitHub Actions or environments with OIDC:
+
+```bash
+# Keyless signing (uses GitHub OIDC token)
+COSIGN_EXPERIMENTAL=1 .github/skills/scripts/skill-runner.sh \
+  security-sign-cosign docker ghcr.io/user/charon:latest
+```
+
+### Sign Docker Image (Key-Based - Local Development)
+
+For local development with generated keys:
+
+```bash
+# Generate key pair first (if you don't have one)
+# cosign generate-key-pair
+# Enter password when prompted
+
+# Sign with local key
+COSIGN_EXPERIMENTAL=0 COSIGN_PRIVATE_KEY="$(cat cosign.key)" \
+  COSIGN_PASSWORD="your-password" \
+  .github/skills/scripts/skill-runner.sh \
+  security-sign-cosign docker charon:local
+```
+
+### Sign File (Binary, Archive, etc.)
+
+```bash
+# Sign a file (creates .sig and .pem files)
+.github/skills/scripts/skill-runner.sh \
+  security-sign-cosign file ./dist/charon-linux-amd64
+```
+
+### Verify Signature
+
+```bash
+# Verify Docker image (keyless)
+cosign verify ghcr.io/user/charon:latest \
+  --certificate-identity-regexp="https://github.com/user/repo" \
+  --certificate-oidc-issuer="https://token.actions.githubusercontent.com"
+
+# Verify file (key-based)
+cosign verify-blob ./dist/charon-linux-amd64 \
+  --signature ./dist/charon-linux-amd64.sig \
+  --certificate ./dist/charon-linux-amd64.pem \
+  --certificate-identity-regexp="https://github.com/user/repo" \
+  --certificate-oidc-issuer="https://token.actions.githubusercontent.com"
+```
+
+## Parameters
+
+| Parameter | Type | Required | Default | Description |
+|-----------|------|----------|---------|-------------|
+| type      | string | No     | docker  | Artifact type (docker, file) |
+| target    | string | Yes    | -       | Docker image tag or file path |
+
+## Environment Variables
+
+| Variable | Required | Default | Description |
+|----------|----------|---------|-------------|
+| COSIGN_EXPERIMENTAL | No | 1 | Enable keyless signing (1=keyless, 0=key-based) |
+| COSIGN_YES | No | true | Non-interactive mode |
+| COSIGN_PRIVATE_KEY | No | "" | Base64-encoded private key (for key-based signing) |
+| COSIGN_PASSWORD | No | "" | Password for private key |
+
+## Signing Modes
+
+### Keyless Signing (Recommended for CI/CD)
+
+- Uses GitHub OIDC tokens for authentication
+- No long-lived keys to manage or secure
+- Signatures stored in Rekor transparency log
+- Certificates issued by Fulcio CA
+- Requires GitHub Actions or similar OIDC provider
+
+**Pros**:
+- No key management burden
+- Public transparency and auditability
+- Automatic certificate rotation
+- Secure by default
+
+**Cons**:
+- Requires network access
+- Depends on Sigstore infrastructure
+- Not suitable for air-gapped environments
+
+### Key-Based Signing (Local Development)
+
+- Uses local private key files
+- Keys managed by developer
+- Suitable for air-gapped environments
+- Requires secure key storage
+
+**Pros**:
+- Works offline
+- Full control over keys
+- No external dependencies
+
+**Cons**:
+- Key management complexity
+- Risk of key compromise
+- Manual key rotation
+- No public transparency log
+
+## Outputs
+
+### Docker Image Signing
+- Signature pushed to registry (no local file)
+- Rekor transparency log entry
+- Certificate (ephemeral for keyless)
+
+### File Signing
+- `<filename>.sig`: Signature file
+- `<filename>.pem`: Certificate file (for keyless)
+- Rekor transparency log entry (for keyless)
+
+## Examples
+
+### Example 1: Sign Local Docker Image (Development)
+
+```bash
+$ docker build -t charon:test .
+$ COSIGN_EXPERIMENTAL=0 \
+  COSIGN_PRIVATE_KEY="$(cat ~/.cosign/cosign.key)" \
+  COSIGN_PASSWORD="my-secure-password" \
+  .github/skills/scripts/skill-runner.sh security-sign-cosign docker charon:test
+
+[INFO] Signing Docker image: charon:test
+[COSIGN] Using key-based signing (COSIGN_EXPERIMENTAL=0)
+[COSIGN] Signing image...
+[SUCCESS] Image signed successfully
+[INFO] Signature pushed to registry
+[INFO] Verification command:
+  cosign verify charon:test --key cosign.pub
+```
+
+### Example 2: Sign Release Binary (Keyless)
+
+```bash
+$ .github/skills/scripts/skill-runner.sh \
+  security-sign-cosign file ./dist/charon-linux-amd64
+
+[INFO] Signing file: ./dist/charon-linux-amd64
+[COSIGN] Using keyless signing (GitHub OIDC)
+[COSIGN] Generating ephemeral certificate...
+[COSIGN] Signing with Fulcio certificate...
+[SUCCESS] File signed successfully
+[INFO] Signature: ./dist/charon-linux-amd64.sig
+[INFO] Certificate: ./dist/charon-linux-amd64.pem
+[INFO] Rekor entry: https://rekor.sigstore.dev/...
+```
+
+### Example 3: CI/CD Pipeline (GitHub Actions)
+
+```yaml
+- name: Install Cosign
+  uses: sigstore/cosign-installer@v3.8.1
+  with:
+    cosign-release: 'v2.4.1'
+
+- name: Sign Docker Image
+  env:
+    DIGEST: ${{ steps.build-and-push.outputs.digest }}
+    IMAGE: ghcr.io/${{ github.repository }}
+  run: |
+    cosign sign --yes ${IMAGE}@${DIGEST}
+
+- name: Verify Signature
+  run: |
+    cosign verify ghcr.io/${{ github.repository }}@${DIGEST} \
+      --certificate-identity-regexp="https://github.com/${{ github.repository }}" \
+      --certificate-oidc-issuer="https://token.actions.githubusercontent.com"
+```
+
+### Example 4: Batch Sign Release Artifacts
+
+```bash
+# Sign all binaries in dist/ directory
+for artifact in ./dist/charon-*; do
+  if [[ -f "$artifact" && ! "$artifact" == *.sig && ! "$artifact" == *.pem ]]; then
+    echo "Signing: $(basename $artifact)"
+    .github/skills/scripts/skill-runner.sh security-sign-cosign file "$artifact"
+  fi
+done
+```
+
+## Key Management Best Practices
+
+### Generating Keys
+
+```bash
+# Generate a new key pair
+cosign generate-key-pair
+
+# This creates:
+# - cosign.key (private key - keep secure!)
+# - cosign.pub (public key - share freely)
+```
+
+### Storing Keys Securely
+
+**DO**:
+- Store private keys in password manager or HSM
+- Encrypt private keys with strong passwords
+- Rotate keys periodically (every 90 days)
+- Use different keys for different environments
+- Backup keys securely (encrypted backups)
+
+**DON'T**:
+- Commit private keys to version control
+- Store keys in plaintext files
+- Share private keys via email or chat
+- Use the same key for CI/CD and local development
+- Hardcode passwords in scripts
+
+### Key Rotation
+
+```bash
+# Generate new key pair
+cosign generate-key-pair --output-key-prefix cosign-new
+
+# Sign new artifacts with new key
+COSIGN_PRIVATE_KEY="$(cat cosign-new.key)" ...
+
+# Update public key in documentation
+# Revoke old key after transition period
+```
+
+## Error Handling
+
+### Common Issues
+
+**Cosign not installed**:
+```bash
+Error: cosign command not found
+Solution: Install Cosign from https://github.com/sigstore/cosign
+Quick install: go install github.com/sigstore/cosign/v2/cmd/cosign@latest
+```
+
+**Missing OIDC token (keyless)**:
+```bash
+Error: OIDC token not available
+Solution: Run in GitHub Actions or use key-based signing (COSIGN_EXPERIMENTAL=0)
+```
+
+**Invalid private key**:
+```bash
+Error: Failed to decrypt private key
+Solution: Verify COSIGN_PASSWORD is correct and key file is valid
+```
+
+**Docker image not found**:
+```bash
+Error: Image not found: charon:test
+Solution: Build or pull the image first
+```
+
+**Registry authentication failed**:
+```bash
+Error: Failed to push signature to registry
+Solution: Authenticate with: docker login <registry>
+```
+
+### Rekor Outages
+
+If Rekor is unavailable, signing will fail. Fallback options:
+
+1. **Wait and retry**: Rekor usually recovers quickly
+2. **Use key-based signing**: Doesn't require Rekor
+3. **Sign without Rekor**: `cosign sign --insecure-ignore-tlog` (not recommended)
+
+## Exit Codes
+
+- **0**: Signing successful
+- **1**: Signing failed
+- **2**: Missing dependencies or invalid parameters

+
+## Notes
+
+- Keyless signing is recommended for CI/CD pipelines
+- Key-based signing is suitable for local development and air-gapped environments
+- All signatures are public and verifiable
+- Rekor transparency log provides audit trail
+- Docker image signatures are stored in the registry, not locally
+- File signatures are stored as `.sig` files alongside the original
+- Certificates for keyless signing are ephemeral and stored with the signature
+
+## Security Considerations
+
+- **Never commit private keys to version control**
+- Use strong passwords for private keys (20+ characters)
+- Rotate keys regularly (every 90 days recommended)
+- Verify signatures before trusting artifacts
+- Monitor Rekor logs for unauthorized signatures
+- Use different keys for different trust levels
+- Consider using HSM for production keys
+- Enable MFA on accounts with signing privileges

+# Security: SLSA Provenance
+
+Generate and verify SLSA (Supply-chain Levels for Software Artifacts) provenance attestations for build transparency and supply chain security.
+
+## Overview
+
+SLSA provenance provides verifiable metadata about how an artifact was built, including the source repository, build platform, dependencies, and build parameters. This skill generates provenance documents, verifies them against policy, and inspects provenance metadata.
+
+SLSA Level 2+ compliance ensures that:
+- Builds are executed on isolated, ephemeral systems
+- Provenance is generated automatically by the build platform
+- Provenance is tamper-proof and cryptographically verifiable
+
+## Features
+
+- Generate SLSA provenance for local artifacts
+- Verify provenance against source repository
+- Inspect provenance metadata
+- Check SLSA level compliance
+- Support Docker images and file artifacts
+- Parse and display provenance in human-readable format
+
+## Prerequisites
+
+- slsa-verifier 2.6.0 or higher
+- jq 1.6 or higher
+- gh (GitHub CLI) 2.62.0 or higher (for downloading attestations)
+- GitHub account (for downloading remote attestations)
+
+## Usage
+
+### Verify Docker Image Provenance
+
+```bash
+# Download and verify provenance from GitHub
+.github/skills/scripts/skill-runner.sh security-slsa-provenance \
+  verify ghcr.io/user/charon:latest github.com/user/charon
+```
+
+### Verify Local Provenance File
+
+```bash
+# Verify a local provenance file against an artifact
+.github/skills/scripts/skill-runner.sh security-slsa-provenance \
+  verify ./dist/charon-linux-amd64 github.com/user/charon provenance.json
+```
+
+### Inspect Provenance Metadata
+
+```bash
+# Parse and display provenance details
+.github/skills/scripts/skill-runner.sh security-slsa-provenance \
+  inspect provenance.json
+```
+
+### Generate Provenance (Local Development)

+
+## Actions
+
+### generate
+
+Generates a basic SLSA provenance document for a local artifact. **Note**: This is for development/testing only. Production provenance must be generated by a trusted build platform (GitHub Actions, Cloud Build, etc.).
+
+**Usage**:
+```bash
+security-slsa-provenance generate <artifact-path>
+```
+
+**Output**: `provenance-<artifact>.json`
+
+### verify
+
+Verifies a provenance document against an artifact and source repository. Checks:
+- Provenance signature is valid
+- Artifact digest matches provenance
+- Source URI matches expected repository
+- SLSA level meets minimum requirements
+
+**Usage**:
+```bash
+# Verify Docker image (downloads attestation automatically)
+security-slsa-provenance verify <image> <source-uri>
+
+# Verify local file with provenance file
+security-slsa-provenance verify <artifact> <source-uri> <provenance-file>
+```
+
+### inspect
+
+Parses and displays provenance metadata in human-readable format. Shows:
+- SLSA level
+- Builder identity
+- Source repository
+- Build parameters
+- Materials (dependencies)
+- Build invocation
+
+**Usage**:
+```bash
+security-slsa-provenance inspect <provenance-file>
+```
+
+## Outputs
+
+### Generate Action
+- `provenance-<artifact>.json`: Generated provenance document
+
+### Verify Action
+- Exit code 0: Verification successful
+- Exit code 1: Verification failed
+- stdout: Verification details and reasons
+
+### Inspect Action
+- Human-readable provenance metadata
+- SLSA level and builder information
+- Source and build details
+

+## SLSA Levels
+
+### Level 1
+- Build process is documented
+- Provenance is generated
+- **Not cryptographically verifiable**
+
+### Level 2 (Recommended Minimum)
+- Build on ephemeral, isolated system
+- Provenance generated by build platform
+- Provenance is signed and verifiable
+- **This skill enforces Level 2 minimum by default**
+
+### Level 3
+- Source and build platform are strongly hardened
+- Audit logs are retained
+- Hermetic, reproducible builds
+- **Recommended for production releases**
+
+## Provenance Structure
+
+A SLSA provenance document contains:
+
+```json
+{
+  "_type": "https://in-toto.io/Statement/v1",
+  "subject": [
+    {
+      "name": "ghcr.io/user/charon",
+      "digest": { "sha256": "..." }
+    }
+  ],
+  "predicateType": "https://slsa.dev/provenance/v1",
+  "predicate": {
+    "buildDefinition": {
+      "buildType": "https://github.com/slsa-framework/slsa-github-generator/...",
+      "externalParameters": {
+        "source": { "uri": "git+https://github.com/user/charon@refs/tags/v1.0.0" }
+      },
+      "internalParameters": {},
+      "resolvedDependencies": [...]
+    },
+    "runDetails": {
+      "builder": { "id": "https://github.com/slsa-framework/..." },

+        "invocationId": "...",
+        "startedOn": "2026-01-10T12:00:00Z",
+        "finishedOn": "2026-01-10T12:05:32Z"
+      }
+    }
+  }
+}
+```
+
+## Error Handling
+
+### Common Issues
+
+**slsa-verifier not installed**:
+```bash
+Error: slsa-verifier command not found
+Solution: Install from https://github.com/slsa-framework/slsa-verifier
+Quick install: go install github.com/slsa-framework/slsa-verifier/v2/cli/slsa-verifier@latest
+```
+
+**Provenance not found**:
+```bash
+Error: No provenance found for image
+Solution: Ensure the image was built with SLSA provenance generation enabled
+```
+
+**Source URI mismatch**:
+```bash
+Error: Source URI mismatch
+Expected: github.com/user/charon
+Found: github.com/attacker/charon
+Solution: Verify you're using the correct image/artifact
+```
+
+**SLSA level too low**:
+```bash
+Error: SLSA level 1 does not meet minimum requirement of 2
+Solution: Rebuild artifact with SLSA Level 2+ generator
+```
+
+**Invalid provenance signature**:
+```bash
+Error: Failed to verify provenance signature
+Solution: Provenance may be tampered or corrupted - do not trust artifact
+```
+
+## Exit Codes
+
+- **0**: Operation successful
+- **1**: Operation failed or verification mismatch
+- **2**: Missing dependencies or invalid parameters

+
+## Notes
+
+- **Production provenance MUST be generated by trusted build platform**
+- Local provenance generation is for testing only
+- SLSA Level 2 is the minimum recommended for production
+- Level 3 provides strongest guarantees but requires hermetic builds
+- Provenance verification requires network access to download attestations
+- GitHub attestations are public and verifiable by anyone
+- Provenance documents are immutable once generated
+
+## Security Considerations
+
+- Never trust artifacts without verified provenance
+- Always verify source URI matches expected repository
+- Require SLSA Level 2+ for production deployments
+- Provenance tampering indicates compromised supply chain
+- Provenance signature must be verified before trusting metadata
+- Local provenance generation bypasses security guarantees

+# Security: Verify SBOM
+
+Verify Software Bill of Materials (SBOM) completeness, scan for vulnerabilities, and perform semantic diff analysis.
+
+## Overview
+
+This skill generates an SBOM for Docker images or local files, compares it with a baseline (if provided), scans for known vulnerabilities using Grype, and reports any critical security issues. It supports both online vulnerability scanning and air-gapped operation modes.
+
+## Features
+
+- Generate SBOM in SPDX format (standardized)
+- Compare with baseline SBOM (semantic diff)
+- Scan for vulnerabilities (Critical/High/Medium/Low)
+- Validate SBOM structure and completeness
+- Support Docker images and local files
+- Air-gapped operation support (skip vulnerability scanning)
+- Detect added/removed packages between builds
+
+## Prerequisites
+
+- Syft 1.17.0 or higher (for SBOM generation)
+- Grype 0.85.0 or higher (for vulnerability scanning)
+- jq 1.6 or higher (for JSON processing)
+- Internet connection (for vulnerability database updates, unless air-gapped mode)
+- Docker (if scanning container images)
+
+## Usage
+
+### Basic Verification
+
+Run with default settings (generate SBOM + scan vulnerabilities):
+
+```bash
+cd /path/to/charon
+.github/skills/scripts/skill-runner.sh security-verify-sbom ghcr.io/user/charon:latest
+```
+
+### Verify Docker Image with Baseline Comparison
+
+Compare current SBOM against a known baseline:
+
+```bash
+.github/skills/scripts/skill-runner.sh security-verify-sbom \
+  charon:local sbom-baseline.json
+```
+
+### Air-Gapped Mode (No Vulnerability Scan)
+
+Verify SBOM structure only, without network access:
+
+```bash
+VULN_SCAN_ENABLED=false .github/skills/scripts/skill-runner.sh \
+  security-verify-sbom charon:local
+```
+
+### Custom SBOM Format
+
+Generate SBOM in CycloneDX format:
+
+```bash
+SBOM_FORMAT=cyclonedx-json .github/skills/scripts/skill-runner.sh \
+  security-verify-sbom charon:local
+```
+
+## Parameters
+
+| Parameter | Type | Required | Default | Description |
+|-----------|------|----------|---------|-------------|
+| target    | string | Yes    | -       | Docker image tag or local image name |
+| baseline  | string | No     | ""      | Path to baseline SBOM for comparison |
+| vuln_scan | boolean | No    | true    | Run vulnerability scan (set VULN_SCAN_ENABLED=false to disable) |
+
+## Environment Variables
+
+| Variable | Required | Default | Description |
+|----------|----------|---------|-------------|
+| SBOM_FORMAT | No | spdx-json | SBOM format (spdx-json or cyclonedx-json) |
+| VULN_SCAN_ENABLED | No | true | Enable vulnerability scanning (set to false for air-gapped) |
+
+## Outputs
+
+- **Success Exit Code**: 0 (no critical issues found)
+- **Error Exit Codes**:
+  - 1: Critical vulnerabilities found or verification failed
+  - 2: Missing dependencies or invalid parameters
+- **Generated Files**:
+  - `sbom-generated.json`: Generated SBOM file
+  - `vuln-results.json`: Vulnerability scan results (if enabled)
+- **Output**: Verification summary to stdout
+
+## Examples
+
+### Example 1: Verify Local Docker Image
+
+```bash
+$ .github/skills/scripts/skill-runner.sh security-verify-sbom charon:test
+[INFO] Generating SBOM for charon:test...
+[SBOM] Generated SBOM contains 247 packages
+[INFO] Scanning for vulnerabilities...
+[VULN] Found: 0 Critical, 2 High, 15 Medium, 42 Low
+[INFO] High vulnerabilities:
+  - CVE-2023-12345 in golang.org/x/crypto (CVSS: 7.5)
+  - CVE-2024-67890 in github.com/example/lib (CVSS: 8.2)
+[SUCCESS] Verification complete - review High severity vulnerabilities
+```
+
+### Example 2: With Baseline Comparison
+
+```bash
+$ .github/skills/scripts/skill-runner.sh security-verify-sbom \
+  charon:latest sbom-baseline.json
+[INFO] Generating SBOM for charon:latest...
+[SBOM] Generated SBOM contains 247 packages
+[INFO] Comparing with baseline...
+[BASELINE] Baseline: 245 packages, Current: 247 packages
+[BASELINE] Delta: +2 packages (0.8% increase)
+[BASELINE] Added packages:
+  - golang.org/x/crypto@v0.30.0
+  - github.com/pkg/errors@v0.9.1
+[BASELINE] Removed packages: (none)
+[INFO] Scanning for vulnerabilities...
+[VULN] Found: 0 Critical, 0 High, 5 Medium, 20 Low
+[SUCCESS] Verification complete (0.8% variance from baseline)
+```

+### Example 3: Air-Gapped Mode

+```bash
+$ VULN_SCAN_ENABLED=false .github/skills/scripts/skill-runner.sh \
+  security-verify-sbom charon:local
+[INFO] Generating SBOM for charon:local...
+[SBOM] Generated SBOM contains 247 packages
+[INFO] Vulnerability scanning disabled (air-gapped mode)
+[SUCCESS] SBOM generation complete
+```
+
+### Example 4: CI/CD Pipeline Integration
+
+```yaml
+# GitHub Actions example
+- name: Verify SBOM
+  run: |
+    .github/skills/scripts/skill-runner.sh \
+      security-verify-sbom ghcr.io/${{ github.repository }}:${{ github.sha }}
+  continue-on-error: false
+```
+
+## Semantic Diff Analysis
+
+When a baseline SBOM is provided, the skill performs semantic comparison:
+
+1. **Package Count Comparison**: Reports total package delta
+2. **Added Packages**: Lists new dependencies with versions
+3. **Removed Packages**: Lists removed dependencies
+4. **Variance Percentage**: Calculates percentage change
+5. **Threshold Check**: Warns if variance exceeds 5%
+
+## Vulnerability Severity Thresholds
+
+**Project Standards**:
+- **CRITICAL**: Must fix before release (blocking) - **Script exits with code 1**
+- **HIGH**: Should fix before release (warning) - **Script continues but logs warning**
+- **MEDIUM**: Fix in next release cycle (informational)
+- **LOW**: Optional, fix as time permits
+
+## Error Handling
+
+### Common Issues
+
+**Syft not installed**:
+```bash
+Error: syft command not found
+Solution: Install Syft from https://github.com/anchore/syft
+```
+
+**Grype not installed**:
+```bash
+Error: grype command not found
+Solution: Install Grype from https://github.com/anchore/grype
+```
+
+**Docker image not found**:
+```bash
+Error: Unable to find image 'charon:test' locally
+Solution: Build the image or pull from registry
+```
+
+**Invalid baseline SBOM**:
+```bash
+Error: Baseline SBOM file not found: sbom-baseline.json
+Solution: Verify the file path or omit baseline parameter
+```
+
+**Network timeout (vulnerability scan)**:
+```bash
+Warning: Failed to update vulnerability database
+Solution: Check internet connection or use air-gapped mode (VULN_SCAN_ENABLED=false)
+```
+
+## Exit Codes
+
+- **0**: Verification successful, no critical vulnerabilities
+- **1**: Critical vulnerabilities found or verification failed
+- **2**: Missing dependencies or invalid parameters

+
+## Notes
+
+- SBOM generation requires read access to Docker images
+- Vulnerability database is updated automatically by Grype
+- Baseline comparison is optional but recommended for drift detection
+- Critical vulnerabilities will cause the script to exit with code 1
+- High vulnerabilities generate warnings but don't block execution
+- Use air-gapped mode when network access is unavailable
+- SPDX format is standardized and recommended over CycloneDX
+
+## Security Considerations
+
+- Never commit SBOM files containing sensitive information
+- Review all High and Critical vulnerabilities before deployment
+- Baseline drift >5% should trigger manual review
+- Air-gapped mode skips vulnerability scanning - use with caution
+- SBOM files can reveal internal architecture - protect accordingly
