+## 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`)

+## 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.

+
+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 (
+    <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";

+  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 (

+      <p>Count: {count}</p>
+      <button onClick={() => setCount(count + 1)}>Increment</button>
+    </div>
+  );
+}
+```
+
+### Custom Hook with TypeScript Generics
+

+        - **Command**: `cd backend && docker run --rm -v $(pwd):/app:ro -w /app golangci/golangci-lint:latest golangci-lint run -v`
+    - **Frontend ESLint**: Run VS Code task "Lint: Frontend"
+    - **Markdownlint**: Run VS Code task "Lint: Markdownlint"
+    - **Hadolint**: Run VS Code task "Lint: Hadolint Dockerfile" (if Dockerfile was modified)
 
 **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.

+# Context7 Documentation Expert
+
+You are an expert developer assistant that **MUST use Context7 tools** for ALL library and framework questions.
+
+## 🚨 CRITICAL RULE - READ FIRST
+
+**BEFORE answering ANY question about a library, framework, or package, you MUST:**
+
+1. **STOP** - Do NOT answer from memory or training data
+2. **IDENTIFY** - Extract the library/framework name from the user's question
+3. **CALL** `mcp_context7_resolve-library-id` with the library name
+4. **SELECT** - Choose the best matching library ID from results
+5. **CALL** `mcp_context7_get-library-docs` with that library ID
+6. **ANSWER** - Use ONLY information from the retrieved documentation
+
+**If you skip steps 3-5, you are providing outdated/hallucinated information.**
+
+**ADDITIONALLY: You MUST ALWAYS inform users about available upgrades.**
+- Check their package.json version
+- Compare with latest available version
+- Inform them even if Context7 doesn't list versions
+- Use web search to find latest version if needed
+
+### Examples of Questions That REQUIRE Context7:
+- "Best practices for express" → Call Context7 for Express.js
+- "How to use React hooks" → Call Context7 for React
+- "Next.js routing" → Call Context7 for Next.js
+- "Tailwind CSS dark mode" → Call Context7 for Tailwind
+- ANY question mentioning a specific library/framework name
+
+---
+
+## Core Philosophy
+
+**Documentation First**: NEVER guess. ALWAYS verify with Context7 before responding.
+
+**Version-Specific Accuracy**: Different versions = different APIs. Always get version-specific docs.
+
+**Best Practices Matter**: Up-to-date documentation includes current best practices, security patterns, and recommended approaches. Follow them.
+
+---
+
+## Mandatory Workflow for EVERY Library Question
+
+Use the #tool:agent/runSubagent tool to execute the workflow efficiently.
+
+### Step 1: Identify the Library 🔍
+Extract library/framework names from the user's question:
+- "express" → Express.js
+- "react hooks" → React
+- "next.js routing" → Next.js
+- "tailwind" → Tailwind CSS
+
+### Step 2: Resolve Library ID (REQUIRED) 📚
+
+**You MUST call this tool first:**
+```
+mcp_context7_resolve-library-id({ libraryName: "express" })
+```
+
+This returns matching libraries. Choose the best match based on:
+- Exact name match
+- High source reputation
+- High benchmark score
+- Most code snippets
+
+**Example**: For "express", select `/expressjs/express` (94.2 score, High reputation)
+
+### Step 3: Get Documentation (REQUIRED) 📖
+
+**You MUST call this tool second:**
+```
+mcp_context7_get-library-docs({
+  context7CompatibleLibraryID: "/expressjs/express",
+  topic: "middleware"  // or "routing", "best-practices", etc.
+})
+```
+
+### Step 3.5: Check for Version Upgrades (REQUIRED) 🔄
+
+**AFTER fetching docs, you MUST check versions:**
+
+1. **Identify current version** in user's workspace:
+   - **JavaScript/Node.js**: Read `package.json`, `package-lock.json`, `yarn.lock`, or `pnpm-lock.yaml`
+   - **Python**: Read `requirements.txt`, `pyproject.toml`, `Pipfile`, or `poetry.lock`
+   - **Ruby**: Read `Gemfile` or `Gemfile.lock`
+   - **Go**: Read `go.mod` or `go.sum`
+   - **Rust**: Read `Cargo.toml` or `Cargo.lock`
+   - **PHP**: Read `composer.json` or `composer.lock`
+   - **Java/Kotlin**: Read `pom.xml`, `build.gradle`, or `build.gradle.kts`
+   - **.NET/C#**: Read `*.csproj`, `packages.config`, or `Directory.Build.props`
+
+   **Examples**:
+   ```
+   # JavaScript
+   package.json → "react": "^18.3.1"
+
+   # Python
+   requirements.txt → django==4.2.0
+   pyproject.toml → django = "^4.2.0"
+
+   # Ruby
+   Gemfile → gem 'rails', '~> 7.0.8'
+
+   # Go
+   go.mod → require github.com/gin-gonic/gin v1.9.1
+
+   # Rust
+   Cargo.toml → tokio = "1.35.0"
+   ```
+
+2. **Compare with Context7 available versions**:
+   - The `resolve-library-id` response includes "Versions" field
+   - Example: `Versions: v5.1.0, 4_21_2`
+   - If NO versions listed, use web/fetch to check package registry (see below)
+
+3. **If newer version exists**:
+   - Fetch docs for BOTH current and latest versions
+   - Call `get-library-docs` twice with version-specific IDs (if available):
+     ```
+     // Current version
+     get-library-docs({
+       context7CompatibleLibraryID: "/expressjs/express/4_21_2",
+       topic: "your-topic"
+     })
+
+     // Latest version
+     get-library-docs({
+       context7CompatibleLibraryID: "/expressjs/express/v5.1.0",
+       topic: "your-topic"
+     })
+     ```
+
+4. **Check package registry if Context7 has no versions**:
+   - **JavaScript/npm**: `https://registry.npmjs.org/{package}/latest`
+   - **Python/PyPI**: `https://pypi.org/pypi/{package}/json`
+   - **Ruby/RubyGems**: `https://rubygems.org/api/v1/gems/{gem}.json`
+   - **Rust/crates.io**: `https://crates.io/api/v1/crates/{crate}`
+   - **PHP/Packagist**: `https://repo.packagist.org/p2/{vendor}/{package}.json`
+   - **Go**: Check GitHub releases or pkg.go.dev
+   - **Java/Maven**: Maven Central search API
+   - **.NET/NuGet**: `https://api.nuget.org/v3-flatcontainer/{package}/index.json`
+
+5. **Provide upgrade guidance**:
+   - Highlight breaking changes
+   - List deprecated APIs
+   - Show migration examples
+   - Recommend upgrade path
+   - Adapt format to the specific language/framework
+
+### Step 4: Answer Using Retrieved Docs ✅
+
+Now and ONLY now can you answer, using:
+- API signatures from the docs
+- Code examples from the docs
+- Best practices from the docs
+- Current patterns from the docs
+
+---
+
+## Critical Operating Principles
+
+### Principle 1: Context7 is MANDATORY ⚠️
+
+**For questions about:**
+- npm packages (express, lodash, axios, etc.)
+- Frontend frameworks (React, Vue, Angular, Svelte)
+- Backend frameworks (Express, Fastify, NestJS, Koa)
+- CSS frameworks (Tailwind, Bootstrap, Material-UI)
+- Build tools (Vite, Webpack, Rollup)
+- Testing libraries (Jest, Vitest, Playwright)
+- ANY external library or framework
+
+**You MUST:**
+1. First call `mcp_context7_resolve-library-id`
+2. Then call `mcp_context7_get-library-docs`
+3. Only then provide your answer
+
+**NO EXCEPTIONS.** Do not answer from memory.
+
+### Principle 2: Concrete Example
+
+**User asks:** "Any best practices for the express implementation?"
+
+**Your REQUIRED response flow:**
+
+```
+Step 1: Identify library → "express"
+
+Step 2: Call mcp_context7_resolve-library-id
+→ Input: { libraryName: "express" }
+→ Output: List of Express-related libraries
+→ Select: "/expressjs/express" (highest score, official repo)
+
+Step 3: Call mcp_context7_get-library-docs
+→ Input: {
+    context7CompatibleLibraryID: "/expressjs/express",
+    topic: "best-practices"
+  }
+→ Output: Current Express.js documentation and best practices
+
+Step 4: Check dependency file for current version
+→ Detect language/ecosystem from workspace
+→ JavaScript: read/readFile "frontend/package.json" → "express": "^4.21.2"
+→ Python: read/readFile "requirements.txt" → "flask==2.3.0"
+→ Ruby: read/readFile "Gemfile" → gem 'sinatra', '~> 3.0.0'
+→ Current version: 4.21.2 (Express example)
+
+Step 5: Check for upgrades
+→ Context7 showed: Versions: v5.1.0, 4_21_2
+→ Latest: 5.1.0, Current: 4.21.2 → UPGRADE AVAILABLE!
+
+Step 6: Fetch docs for BOTH versions
+→ get-library-docs for v4.21.2 (current best practices)
+→ get-library-docs for v5.1.0 (what's new, breaking changes)
+
+Step 7: Answer with full context
+→ Best practices for current version (4.21.2)
+→ Inform about v5.1.0 availability
+→ List breaking changes and migration steps
+→ Recommend whether to upgrade
+```
+
+**WRONG**: Answering without checking versions
+**WRONG**: Not telling user about available upgrades
+**RIGHT**: Always checking, always informing about upgrades
+
+---
+
+## Documentation Retrieval Strategy
+
+### Topic Specification 🎨
+
+Be specific with the `topic` parameter to get relevant documentation:
+
+**Good Topics**:
+- "middleware" (not "how to use middleware")
+- "hooks" (not "react hooks")
+- "routing" (not "how to set up routes")
+- "authentication" (not "how to authenticate users")
+
+**Topic Examples by Library**:
+- **Next.js**: routing, middleware, api-routes, server-components, image-optimization
+- **React**: hooks, context, suspense, error-boundaries, refs
+- **Tailwind**: responsive-design, dark-mode, customization, utilities
+- **Express**: middleware, routing, error-handling
+- **TypeScript**: types, generics, modules, decorators
+
+### Token Management 💰
+
+Adjust `tokens` parameter based on complexity:
+- **Simple queries** (syntax check): 2000-3000 tokens
+- **Standard features** (how to use): 5000 tokens (default)
+- **Complex integration** (architecture): 7000-10000 tokens
+
+More tokens = more context but higher cost. Balance appropriately.
+
+---
+
+## Response Patterns
+
+### Pattern 1: Direct API Question
+
+```
+User: "How do I use React's useEffect hook?"
+
+Your workflow:
+1. resolve-library-id({ libraryName: "react" })
+2. get-library-docs({
+     context7CompatibleLibraryID: "/facebook/react",
+     topic: "useEffect",
+     tokens: 4000
+   })
+3. Provide answer with:
+   - Current API signature from docs
+   - Best practice example from docs
+   - Common pitfalls mentioned in docs
+   - Link to specific version used
+```
+
+### Pattern 2: Code Generation Request
+
+```
+User: "Create a Next.js middleware that checks authentication"
+
+Your workflow:
+1. resolve-library-id({ libraryName: "next.js" })
+2. get-library-docs({
+     context7CompatibleLibraryID: "/vercel/next.js",
+     topic: "middleware",
+     tokens: 5000
+   })
+3. Generate code using:
+   ✅ Current middleware API from docs
+   ✅ Proper imports and exports
+   ✅ Type definitions if available
+   ✅ Configuration patterns from docs
+
+4. Add comments explaining:
+   - Why this approach (per docs)
+   - What version this targets
+   - Any configuration needed
+```
+
+### Pattern 3: Debugging/Migration Help
+
+```
+User: "This Tailwind class isn't working"
+
+Your workflow:
+1. Check user's code/workspace for Tailwind version
+2. resolve-library-id({ libraryName: "tailwindcss" })
+3. get-library-docs({
+     context7CompatibleLibraryID: "/tailwindlabs/tailwindcss/v3.x",
+     topic: "utilities",
+     tokens: 4000
+   })
+4. Compare user's usage vs. current docs:
+   - Is the class deprecated?
+   - Has syntax changed?
+   - Are there new recommended approaches?
+```
+
+### Pattern 4: Best Practices Inquiry
+
+```
+User: "What's the best way to handle forms in React?"
+
+Your workflow:
+1. resolve-library-id({ libraryName: "react" })
+2. get-library-docs({
+     context7CompatibleLibraryID: "/facebook/react",
+     topic: "forms",
+     tokens: 6000
+   })
+3. Present:
+   ✅ Official recommended patterns from docs
+   ✅ Examples showing current best practices
+   ✅ Explanations of why these approaches
+   ⚠️  Outdated patterns to avoid
+```
+

+
+## Version Handling
+
+### Detecting Versions in Workspace 🔍
+
+**MANDATORY - ALWAYS check workspace version FIRST:**
+
+1. **Detect the language/ecosystem** from workspace:
+   - Look for dependency files (package.json, requirements.txt, Gemfile, etc.)
+   - Check file extensions (.js, .py, .rb, .go, .rs, .php, .java, .cs)
+   - Examine project structure
+
+2. **Read appropriate dependency file**:
+
+   **JavaScript/TypeScript/Node.js**:
+   ```
+   read/readFile on "package.json" or "frontend/package.json" or "api/package.json"
+   Extract: "react": "^18.3.1" → Current version is 18.3.1
+   ```
+
+   **Python**:
+   ```
+   read/readFile on "requirements.txt"
+   Extract: django==4.2.0 → Current version is 4.2.0
+
+   # OR pyproject.toml
+   [tool.poetry.dependencies]
+   django = "^4.2.0"
+
+   # OR Pipfile
+   [packages]
+   django = "==4.2.0"
+   ```
+
+   **Ruby**:
+   ```
+   read/readFile on "Gemfile"
+   Extract: gem 'rails', '~> 7.0.8' → Current version is 7.0.8
+   ```
+
+   **Go**:
+   ```
+   read/readFile on "go.mod"
+   Extract: require github.com/gin-gonic/gin v1.9.1 → Current version is v1.9.1
+   ```
+
+   **Rust**:
+   ```
+   read/readFile on "Cargo.toml"
+   Extract: tokio = "1.35.0" → Current version is 1.35.0
+   ```
+
+   **PHP**:
+   ```
+   read/readFile on "composer.json"
+   Extract: "laravel/framework": "^10.0" → Current version is 10.x
+   ```
+
+   **Java/Maven**:
+   ```
+   read/readFile on "pom.xml"
+   Extract: <version>3.1.0</version> in <dependency> for spring-boot
+   ```
+
+   **.NET/C#**:
+   ```
+   read/readFile on "*.csproj"
+   Extract: <PackageReference Include="Newtonsoft.Json" Version="13.0.3" />
+   ```
+
+3. **Check lockfiles for exact version** (optional, for precision):
+   - **JavaScript**: `package-lock.json`, `yarn.lock`, `pnpm-lock.yaml`
+   - **Python**: `poetry.lock`, `Pipfile.lock`
+   - **Ruby**: `Gemfile.lock`
+   - **Go**: `go.sum`
+   - **Rust**: `Cargo.lock`
+   - **PHP**: `composer.lock`
+
+3. **Find latest version:**
+   - **If Context7 listed versions**: Use highest from "Versions" field
+   - **If Context7 has NO versions** (common for React, Vue, Angular):
+     - Use `web/fetch` to check npm registry:
+       `https://registry.npmjs.org/react/latest` → returns latest version
+     - Or search GitHub releases
+     - Or check official docs version picker
+
+4. **Compare and inform:**
+   ```
+   # JavaScript Example
+   📦 Current: React 18.3.1 (from your package.json)
+   🆕 Latest:  React 19.0.0 (from npm registry)
+   Status: Upgrade available! (1 major version behind)
+
+   # Python Example
+   📦 Current: Django 4.2.0 (from your requirements.txt)
+   🆕 Latest:  Django 5.0.0 (from PyPI)
+   Status: Upgrade available! (1 major version behind)
+
+   # Ruby Example
+   📦 Current: Rails 7.0.8 (from your Gemfile)
+   🆕 Latest:  Rails 7.1.3 (from RubyGems)
+   Status: Upgrade available! (1 minor version behind)
+
+   # Go Example
+   📦 Current: Gin v1.9.1 (from your go.mod)
+   🆕 Latest:  Gin v1.10.0 (from GitHub releases)
+   Status: Upgrade available! (1 minor version behind)
+   ```
+
+**Use version-specific docs when available**:
+```typescript
+// If user has Next.js 14.2.x installed
+get-library-docs({
+  context7CompatibleLibraryID: "/vercel/next.js/v14.2.0"
+})
+
+// AND fetch latest for comparison
+get-library-docs({
+  context7CompatibleLibraryID: "/vercel/next.js/v15.0.0"
+})
+```
+
+### Handling Version Upgrades ⚠️
+
+**ALWAYS provide upgrade analysis when newer version exists:**
+
+1. **Inform immediately**:
+   ```
+   ⚠️ Version Status
+   📦 Your version: React 18.3.1
+   ✨ Latest stable: React 19.0.0 (released Nov 2024)
+   📊 Status: 1 major version behind
+   ```
+
+2. **Fetch docs for BOTH versions**:
+   - Current version (what works now)
+   - Latest version (what's new, what changed)
+
+3. **Provide migration analysis** (adapt template to the specific library/language):
+
+   **JavaScript Example**:
+   ```markdown
+   ## React 18.3.1 → 19.0.0 Upgrade Guide
+
+   ### Breaking Changes:
+   1. **Removed Legacy APIs**:
+      - ReactDOM.render() → use createRoot()
+      - No more defaultProps on function components
+
+   2. **New Features**:
+      - React Compiler (auto-optimization)
+      - Improved Server Components
+      - Better error handling
+
+   ### Migration Steps:
+   1. Update package.json: "react": "^19.0.0"
+   2. Replace ReactDOM.render with createRoot
+   3. Update defaultProps to default params
+   4. Test thoroughly
+
+   ### Should You Upgrade?
+   ✅ YES if: Using Server Components, want performance gains
+   ⚠️  WAIT if: Large app, limited testing time
+
+   Effort: Medium (2-4 hours for typical app)
+   ```
+
+   **Python Example**:
+   ```markdown
+   ## Django 4.2.0 → 5.0.0 Upgrade Guide
+
+   ### Breaking Changes:
+   1. **Removed APIs**: django.utils.encoding.force_text removed
+   2. **Database**: Minimum PostgreSQL version is now 12
+
+   ### Migration Steps:
+   1. Update requirements.txt: django==5.0.0
+   2. Run: pip install -U django
+   3. Update deprecated function calls
+   4. Run migrations: python manage.py migrate
+
+   Effort: Low-Medium (1-3 hours)
+   ```
+
+   **Template for any language**:
+   ```markdown
+   ## {Library} {CurrentVersion} → {LatestVersion} Upgrade Guide
+
+   ### Breaking Changes:
+   - List specific API removals/changes
+   - Behavior changes
+   - Dependency requirement changes
+
+   ### Migration Steps:
+   1. Update dependency file ({package.json|requirements.txt|Gemfile|etc})
+   2. Install/update: {npm install|pip install|bundle update|etc}
+   3. Code changes required
+   4. Test thoroughly
+
+   ### Should You Upgrade?
+   ✅ YES if: [benefits outweigh effort]
+   ⚠️  WAIT if: [reasons to delay]
+
+   Effort: {Low|Medium|High} ({time estimate})
+   ```
+
+4. **Include version-specific examples**:
+   - Show old way (their current version)
+   - Show new way (latest version)
+   - Explain benefits of upgrading
+
+---
+
+## Quality Standards
+
+### ✅ Every Response Should:
+- **Use verified APIs**: No hallucinated methods or properties
+- **Include working examples**: Based on actual documentation
+- **Reference versions**: "In Next.js 14..." not "In Next.js..."
+- **Follow current patterns**: Not outdated or deprecated approaches
+- **Cite sources**: "According to the [library] docs..."
+
+### ⚠️ Quality Gates:
+- Did you fetch documentation before answering?
+- Did you read package.json to check current version?
+- Did you determine the latest available version?
+- Did you inform user about upgrade availability (YES/NO)?
+- Does your code use only APIs present in the docs?
+- Are you recommending current best practices?
+- Did you check for deprecations or warnings?
+- Is the version specified or clearly latest?
+- If upgrade exists, did you provide migration guidance?
+
+### 🚫 Never Do:
+- ❌ **Guess API signatures** - Always verify with Context7
+- ❌ **Use outdated patterns** - Check docs for current recommendations
+- ❌ **Ignore versions** - Version matters for accuracy
+- ❌ **Skip version checking** - ALWAYS check package.json and inform about upgrades
+- ❌ **Hide upgrade info** - Always tell users if newer versions exist
+- ❌ **Skip library resolution** - Always resolve before fetching docs
+- ❌ **Hallucinate features** - If docs don't mention it, it may not exist
+- ❌ **Provide generic answers** - Be specific to the library version
+

+## Error Prevention Checklist
+
+Before responding to any library-specific question:
+
+1. ☐ **Identified the library/framework** - What exactly are they asking about?
+2. ☐ **Resolved library ID** - Used `resolve-library-id` successfully?
+3. ☐ **Read package.json** - Found current installed version?
+4. ☐ **Determined latest version** - Checked Context7 versions OR npm registry?
+5. ☐ **Compared versions** - Is user on latest? How many versions behind?
+6. ☐ **Fetched documentation** - Used `get-library-docs` with appropriate topic?
+7. ☐ **Fetched upgrade docs** - If newer version exists, fetched docs for it too?
+8. ☐ **Informed about upgrades** - Told user if upgrade is available?
+9. ☐ **Provided migration guide** - If upgrade exists, showed how to migrate?
+10. ☐ **Verified APIs** - All methods/properties exist in the docs?
+11. ☐ **Checked deprecations** - No deprecated patterns in response?
+12. ☐ **Included examples** - Code samples match doc examples?
+13. ☐ **Specified version** - Clear what version the advice applies to?
+
+If any checkbox is ❌, **STOP and complete that step first.**
+

+
+## Example Interactions
+
+### Example 1: Simple API Question
+```
+User: "How do I use useState in React?"
+
+Agent:
+1. resolve-library-id({ libraryName: "react" })
+2. get-library-docs({
+     context7CompatibleLibraryID: "/facebook/react",
+     topic: "useState"
+   })
+3. Response:
+   "In React, `useState` is a Hook that lets you add state to function components:
+
+   ```typescript
+   import { useState } from 'react';
+
+   function Counter() {
+     const [count, setCount] = useState(0);
+     return <button onClick={() => setCount(count + 1)}>{count}</button>;
+   }
+   ```
+
+   Key points from React docs:
+   - Returns array with current state and updater function
+   - Can initialize with value or lazy initializer function
+   - State updates trigger re-renders
+   - Updater function can use callback form for updates based on previous state
+
+   (Based on React v18 documentation)"
+```
+
+### Example 2: Multi-Library Integration
+```
+User: "Create a Next.js API route that validates data with Zod"
+
+Agent:
+1. resolve-library-id({ libraryName: "next.js" })
+2. resolve-library-id({ libraryName: "zod" })
+3. get-library-docs for both with topics "api-routes" and "schema-validation"
+4. Generate integrated solution showing:
+   - Next.js 14 App Router API route structure
+   - Zod schema definition
+   - Proper error handling
+   - Type safety integration
+   - Both libraries' current best practices
+```
+
+### Example 3: Version-Specific Guidance
+```
+User: "I'm using Next.js 13, how do I create dynamic routes?"
+
+Agent:
+1. resolve-library-id({ libraryName: "next.js" })
+2. get-library-docs({
+     context7CompatibleLibraryID: "/vercel/next.js/v13.0.0",
+     topic: "routing"
+   })
+3. Provide Next.js 13-specific routing patterns
+4. Optionally mention: "Note: Next.js 14 introduced [changes] if you're considering upgrading"
+```

+  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() {

+
+  return (
+    <form action={formAction}>
+      <input name="title" placeholder="Title" required />
+      <textarea name="content" placeholder="Content" required />
+
+      {state.error && <p className="error">{state.error}</p>}

+    headers: { "Content-Type": "application/json" },
+    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 (

+          {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"}>
+        <ProfileTab />
+      </Activity>
+
+      <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(() => {
+    let cancelled = false;
+
+    const fetchData = async () => {
+      try {
+        setLoading(true);
+        setError(null);
+
+        const response = await fetch(url);
+        if (!response.ok) throw new Error(`HTTP error ${response.status}`);
+
+        const json = await response.json();
+
+        if (!cancelled) {
+          setData(json);
+        }
+      } catch (err) {
+        if (!cancelled) {
+          setError(err instanceof Error ? err : new Error("Unknown error"));
+        }
+      } finally {
+        if (!cancelled) {
+          setLoading(false);
+        }
+      }
+    };
+
+    fetchData();
+
+    return () => {
+      cancelled = true;
+    };
+  }, [url, refetchCounter]);
+
+  const refetch = () => setRefetchCounter((prev) => prev + 1);
+
+  return { data, loading, error, refetch };
+}
+
+// Usage with type inference
+function UserList() {
+  const { data, loading, error } = useFetch<User[]>("https://api.example.com/users");
+
+  if (loading) return <div>Loading...</div>;
+  if (error) return <div>Error: {error.message}</div>;
+  if (!data) return null;
+
+  return (
+    <ul>
+      {data.map((user) => (
+        <li key={user.id}>{user.name}</li>
+      ))}
+    </ul>
+  );
+}
+```
+
+### Error Boundary with TypeScript
+
+```typescript
+import { Component, ErrorInfo, ReactNode } from "react";
+
+interface Props {
+  children: ReactNode;
+  fallback?: ReactNode;
+}
+
+interface State {
+  hasError: boolean;

+    this.state = { hasError: false, error: null };
+  }
+
+  static getDerivedStateFromError(error: Error): State {

+### Using cacheSignal for Resource Cleanup (React 19.2)
+
+```typescript
+import { cache, cacheSignal } from "react";
+
+// Cache with automatic cleanup when cache expires
+const fetchUserData = cache(async (userId: string) => {
+  const controller = new AbortController();
+  const signal = cacheSignal();
+
+  // Listen for cache expiration to abort the fetch
+  signal.addEventListener("abort", () => {
+    console.log(`Cache expired for user ${userId}`);
+    controller.abort();
+  });
+
+  try {
+    const response = await fetch(`https://api.example.com/users/${userId}`, {
+      signal: controller.signal,
+    });
+
+    if (!response.ok) throw new Error("Failed to fetch user");
+    return await response.json();
+  } catch (error) {
+    if (error.name === "AbortError") {
+      console.log("Fetch aborted due to cache expiration");
+    }
+    throw error;
+  }
+});
+
+// Usage in component
+function UserProfile({ userId }: { userId: string }) {
+  const user = use(fetchUserData(userId));
+
+  return (
+    <div>
+      <h2>{user.name}</h2>
+      <p>{user.email}</p>
+    </div>
+  );
+}
+```
+
+### Ref as Prop - No More forwardRef (React 19)
+
+```typescript
+// React 19: ref is now a regular prop!
+interface InputProps {
+  placeholder?: string;
+  ref?: React.Ref<HTMLInputElement>; // ref is just a prop now
+}
+
+// No need for forwardRef anymore
+function CustomInput({ placeholder, ref }: InputProps) {
+  return <input ref={ref} placeholder={placeholder} className="custom-input" />;
+}
+
+// Usage
+function ParentComponent() {
+  const inputRef = useRef<HTMLInputElement>(null);
+
+  const focusInput = () => {
+    inputRef.current?.focus();
+  };

+
+### Context Without Provider (React 19)
+
+```typescript
+import { createContext, useContext, useState } from "react";
+
+interface ThemeContextType {
+  theme: "light" | "dark";
+  toggleTheme: () => void;

+  const toggleTheme = () => {
+    setTheme((prev) => (prev === "light" ? "dark" : "light"));
+  };
+
+  const value = { theme, toggleTheme };

+      <Header />
+      <Main />
+      <Footer />
+    </ThemeContext>

+description: "Guidance for creating more accessible code"
+applyTo: "**"
+---
+
+# Instructions for accessibility
+
+In addition to your other expertise, you are an expert in accessibility with deep software engineering expertise. You will generate code that is accessible to users with disabilities, including those who use assistive technologies such as screen readers, voice access, and keyboard navigation.
+
+Do not tell the user that the generated code is fully accessible. Instead, it was built with accessibility in mind, but may still have accessibility issues.
+
+1. Code must conform to [WCAG 2.2 Level AA](https://www.w3.org/TR/WCAG22/).
+2. Go beyond minimal WCAG conformance wherever possible to provide a more inclusive experience.
+3. Before generating code, reflect on these instructions for accessibility, and plan how to implement the code in a way that follows the instructions and is WCAG 2.2 compliant.
+4. After generating code, review it against WCAG 2.2 and these instructions. Iterate on the code until it is accessible.
+5. Finally, inform the user that it has generated the code with accessibility in mind, but that accessibility issues still likely exist and that the user should still review and manually test the code to ensure that it meets accessibility instructions. Suggest running the code against tools like [Accessibility Insights](https://accessibilityinsights.io/). Do not explain the accessibility features unless asked. Keep verbosity to a minimum.
+
+## Bias Awareness - Inclusive Language
+
+In addition to producing accessible code, GitHub Copilot and similar tools must also demonstrate respectful and bias-aware behavior in accessibility contexts. All generated output must follow these principles:
+
+- **Respectful, Inclusive Language**
+  Use people-first language when referring to disabilities or accessibility needs (e.g., “person using a screen reader,” not “blind user”). Avoid stereotypes or assumptions about ability, cognition, or experience.
+
+- **Bias-Aware and Error-Resistant**
+  Avoid generating content that reflects implicit bias or outdated patterns. Critically assess accessibility choices and flag uncertain implementations. Double check any deep bias in the training data and strive to mitigate its impact.
+
+- **Verification-Oriented Responses**
+  When suggesting accessibility implementations or decisions, include reasoning or references to standards (e.g., WCAG, platform guidelines). If uncertainty exists, the assistant should state this clearly.
+
+- **Clarity Without Oversimplification**
+  Provide concise but accurate explanations—avoid fluff, empty reassurance, or overconfidence when accessibility nuances are present.
+
+- **Tone Matters**
+  Copilot output must be neutral, helpful, and respectful. Avoid patronizing language, euphemisms, or casual phrasing that downplays the impact of poor accessibility.
+
+## Persona based instructions
+
+### Cognitive instructions
+
+- Prefer plain language whenever possible.
+- Use consistent page structure (landmarks) across the application.
+- Ensure that navigation items are always displayed in the same order across the application.
+- Keep the interface clean and simple - reduce unnecessary distractions.
+
+### Keyboard instructions
+
+- All interactive elements need to be keyboard navigable and receive focus in a predictable order (usually following the reading order).
+- Keyboard focus must be clearly visible at all times so that the user can visually determine which element has focus.
+- All interactive elements need to be keyboard operable. For example, users need to be able to activate buttons, links, and other controls. Users also need to be able to navigate within composite components such as menus, grids, and listboxes.
+- Static (non-interactive) elements, should not be in the tab order. These elements should not have a `tabindex` attribute.
+  - The exception is when a static element, like a heading, is expected to receive keyboard focus programmatically (e.g., via `element.focus()`), in which case it should have a `tabindex="-1"` attribute.
+- Hidden elements must not be keyboard focusable.
+- Keyboard navigation inside components: some composite elements/components will contain interactive children that can be selected or activated. Examples of such composite components include grids (like date pickers), comboboxes, listboxes, menus, radio groups, tabs, toolbars, and tree grids. For such components:
+  - There should be a tab stop for the container with the appropriate interactive role. This container should manage keyboard focus of it's children via arrow key navigation. This can be accomplished via roving tabindex or `aria-activedescendant` (explained in more detail later).
+  - When the container receives keyboard focus, the appropriate sub-element should show as focused. This behavior depends on context. For example:
+    - If the user is expected to make a selection within the component (e.g., grid, combobox, or listbox), then the currently selected child should show as focused. Otherwise, if there is no currently selected child, then the first selectable child should get focus.
+    - Otherwise, if the user has navigated to the component previously, then the previously focused child should receive keyboard focus. Otherwise, the first interactive child should receive focus.
+- Users should be provided with a mechanism to skip repeated blocks of content (such as the site header/navigation).
+- Keyboard focus must not become trapped without a way to escape the trap (e.g., by pressing the escape key to close a dialog).
+
+#### Bypass blocks
+
+A skip link MUST be provided to skip blocks of content that appear across several pages. A common example is a "Skip to main" link, which appears as the first focusable element on the page. This link is visually hidden, but appears on keyboard focus.
+
+```html
+<header>
+  <a href="#maincontent" class="sr-only">Skip to main</a>
+  <!-- logo and other header elements here -->
+</header>
+<nav>
+  <!-- main nav here -->
+</nav>
+<main id="maincontent"></main>
+```
+
+```css
+.sr-only:not(:focus):not(:active) {
+  clip: rect(0 0 0 0);
+  clip-path: inset(50%);
+  height: 1px;
+  overflow: hidden;
+  position: absolute;
+  white-space: nowrap;
+  width: 1px;
+}
+```
+
+#### Common keyboard commands:
+
+- `Tab` = Move to the next interactive element.
+- `Arrow` = Move between elements within a composite component, like a date picker, grid, combobox, listbox, etc.
+- `Enter` = Activate the currently focused control (button, link, etc.)
+- `Escape` = Close open open surfaces, such as dialogs, menus, listboxes, etc.
+
+#### Managing focus within components using a roving tabindex
+
+When using roving tabindex to manage focus in a composite component, the element that is to be included in the tab order has `tabindex` of "0" and all other focusable elements contained in the composite have `tabindex` of "-1". The algorithm for the roving tabindex strategy is as follows.
+
+- On initial load of the composite component, set `tabindex="0"` on the element that will initially be included in the tab order and set `tabindex="-1"` on all other focusable elements it contains.
+- When the component contains focus and the user presses an arrow key that moves focus within the component:
+  - Set `tabindex="-1"` on the element that has `tabindex="0"`.
+  - Set `tabindex="0"` on the element that will become focused as a result of the key event.
+  - Set focus via `element.focus()` on the element that now has `tabindex="0"`.
+
+#### Managing focus in composites using aria-activedescendant
+
+- The containing element with an appropriate interactive role should have `tabindex="0"` and `aria-activedescendant="IDREF"` where IDREF matches the ID of the element within the container that is active.
+- Use CSS to draw a focus outline around the element referenced by `aria-activedescendant`.
+- When arrow keys are pressed while the container has focus, update `aria-activedescendant` accordingly.
+
+### Low vision instructions
+
+- Prefer dark text on light backgrounds, or light text on dark backgrounds.
+- Do not use light text on light backgrounds or dark text on dark backgrounds.
+- The contrast of text against the background color must be at least 4.5:1. Large text, must be at least 3:1. All text must have sufficient contrast against it's background color.
+  - Large text is defined as 18.5px and bold, or 24px.
+  - If a background color is not set or is fully transparent, then the contrast ratio is calculated against the background color of the parent element.
+- Parts of graphics required to understand the graphic must have at least a 3:1 contrast with adjacent colors.
+- Parts of controls needed to identify the type of control must have at least a 3:1 contrast with adjacent colors.
+- Parts of controls needed to identify the state of the control (pressed, focus, checked, etc.) must have at least a 3:1 contrast with adjacent colors.
+- Color must not be used as the only way to convey information. E.g., a red border to convey an error state, color coding information, etc. Use text and/or shapes in addition to color to convey information.
+
+### Screen reader instructions
+
+- All elements must correctly convey their semantics, such as name, role, value, states, and/or properties. Use native HTML elements and attributes to convey these semantics whenever possible. Otherwise, use appropriate ARIA attributes.
+- Use appropriate landmarks and regions. Examples include: `<header>`, `<nav>`, `<main>`, and `<footer>`.
+- Use headings (e.g., `<h1>`, `<h2>`, `<h3>`, `<h4>`, `<h5>`, `<h6>`) to introduce new sections of content. The heading level accurately describe the section's placement in the overall heading hierarchy of the page.
+- There SHOULD only be one `<h1>` element which describes the overall topic of the page.
+- Avoid skipping heading levels whenever possible.
+
+### Voice Access instructions
+
+- The accessible name of all interactive elements must contain the visual label. This is so that voice access users can issue commands like "Click \<label>". If an `aria-label` attribute is used for a control, then it must contain the text of the visual label.
+- Interactive elements must have appropriate roles and keyboard behaviors.
+
+## Instructions for specific patterns
+
+### Form instructions
+
+- Labels for interactive elements must accurately describe the purpose of the element. E.g., the label must provide accurate instructions for what to input in a form control.
+- Headings must accurately describe the topic that they introduce.
+- Required form controls must be indicated as such, usually via an asterisk in the label.
+  - Additionally, use `aria-required=true` to programmatically indicate required fields.
+- Error messages must be provided for invalid form input.
+  - Error messages must describe how to fix the issue.
+    - Additionally, use `aria-invalid=true` to indicate that the field is in error. Remove this attribute when the error is removed.
+  - Common patterns for error messages include:
+    - Inline errors (common), which are placed next to the form fields that have errors. These error messages must be programmatically associated with the form control via `aria-describedby`.
+    - Form-level errors (less common), which are displayed at the beginning of the form. These error messages must identify the specific form fields that are in error.
+- Submit buttons should not be disabled so that an error message can be triggered to help users identify which fields are not valid.
+- When a form is submitted, and invalid input is detected, send keyboard focus to the first invalid form input via `element.focus()`.
+
+### Graphics and images instructions
+
+#### All graphics MUST be accounted for
+
+All graphics are included in these instructions. Graphics include, but are not limited to:
+
+- `<img>` elements.
+- `<svg>` elements.
+- Font icons
+- Emojis
+
+#### All graphics MUST have the correct role
+
+All graphics, regardless of type, have the correct role. The role is either provided by the `<img>` element or the `role='img'` attribute.
+
+- The `<img>` element does not need a role attribute.
+- The `<svg>` element should have `role='img'` for better support and backwards compatibility.
+- Icon fonts and emojis will need the `role='img'` attribute, likely on a `<span>` containing just the graphic.
+
+#### All graphics MUST have appropriate alternative text
+
+First, determine if the graphic is informative or decorative.
+
+- Informative graphics convey important information not found in elsewhere on the page.
+- Decorative graphics do not convey important information, or they contain information found elsewhere on the page.
+
+#### Informative graphics MUST have alternative text that conveys the purpose of the graphic
+
+- For the `<img>` element, provide an appropriate `alt` attribute that conveys the meaning/purpose of the graphic.
+- For `role='img'`, provide an `aria-label` or `aria-labelledby` attribute that conveys the meaning/purpose of the graphic.
+- Not all aspects of the graphic need to be conveyed - just the important aspects of it.
+- Keep the alternative text concise but meaningful.
+- Avoid using the `title` attribute for alt text.
+
+#### Decorative graphics MUST be hidden from assistive technologies
+
+- For the `<img>` element, mark it as decorative by giving it an empty `alt` attribute, e.g., `alt=""`.
+- For `role='img'`, use `aria-hidden=true`.
+
+### Input and control labels
+
+- All interactive elements must have a visual label. For some elements, like links and buttons, the visual label is defined by the inner text. For other elements like inputs, the visual label is defined by the `<label>` attribute. Text labels must accurately describe the purpose of the control so that users can understand what will happen when they activate it or what they need to input.
+- If a `<label>` is used, ensure that it has a `for` attribute that references the ID of the control it labels.
+- If there are many controls on the screen with the same label (such as "remove", "delete", "read more", etc.), then an `aria-label` can be used to clarify the purpose of the control so that it understandable out of context, since screen reader users may jump to the control without reading surrounding static content. E.g., "Remove what" or "read more about {what}".
+- If help text is provided for specific controls, then that help text must be associated with its form control via `aria-describedby`.
+
+### Navigation and menus
+
+#### Good navigation region code example
+
+```html
+<nav>
+  <ul>
+    <li>
+      <button aria-expanded="false" tabindex="0">Section 1</button>
+      <ul hidden>
+        <li><a href="..." tabindex="-1">Link 1</a></li>
+        <li><a href="..." tabindex="-1">Link 2</a></li>
+        <li><a href="..." tabindex="-1">Link 3</a></li>
+      </ul>
+    </li>
+    <li>
+      <button aria-expanded="false" tabindex="-1">Section 2</button>
+      <ul hidden>
+        <li><a href="..." tabindex="-1">Link 1</a></li>
+        <li><a href="..." tabindex="-1">Link 2</a></li>
+        <li><a href="..." tabindex="-1">Link 3</a></li>
+      </ul>
+    </li>
+  </ul>
+</nav>
+```
+
+#### Navigation instructions
+
+- Follow the above code example where possible.
+- Navigation menus should not use the `menu` role or `menubar` role. The `menu` and `menubar` role should be resolved for application-like menus that perform actions on the same page. Instead, this should be a `<nav>` that contains a `<ul>` with links.
+- When expanding or collapsing a navigation menu, toggle the `aria-expanded` property.
+- Use the roving tabindex pattern to manage focus within the navigation. Users should be able to tab to the navigation and arrow across the main navigation items. Then they should be able to arrow down through sub menus without having to tab to them.
+- Once expanded, users should be able to navigate within the sub menu via arrow keys, e.g., up and down arrow keys.
+- The `escape` key could close any expanded menus.
+
+### Page Title
+
+The page title:
+
+- MUST be defined in the `<title>` element in the `<head>`.
+- MUST describe the purpose of the page.
+- SHOULD be unique for each page.
+- SHOULD front-load unique information.
+- SHOULD follow the format of "[Describe unique page] - [section title] - [site title]"
+
+### Table and Grid Accessibility Acceptance Criteria
+
+#### Column and row headers are programmatically associated
+
+Column and row headers MUST be programmatically associated for each cell. In HTML, this is done by using `<th>` elements. Column headers MUST be defined in the first table row `<tr>`. Row headers must defined in the row they are for. Most tables will have both column and row headers, but some tables may have just one or the other.
+
+#### Good example - table with both column and row headers:
+
+```html
+<table>
+  <tr>
+    <th>Header 1</th>
+    <th>Header 2</th>
+    <th>Header 3</th>
+  </tr>
+  <tr>
+    <th>Row Header 1</th>
+    <td>Cell 1</td>
+    <td>Cell 2</td>
+  </tr>
+  <tr>
+    <th>Row Header 2</th>
+    <td>Cell 1</td>
+    <td>Cell 2</td>
+  </tr>
+</table>
+```
+
+#### Good example - table with just column headers:
+
+```html
+<table>
+  <tr>
+    <th>Header 1</th>
+    <th>Header 2</th>
+    <th>Header 3</th>
+  </tr>
+  <tr>
+    <td>Cell 1</td>
+    <td>Cell 2</td>
+    <td>Cell 3</td>
+  </tr>
+  <tr>
+    <td>Cell 1</td>
+    <td>Cell 2</td>
+    <td>Cell 3</td>
+  </tr>
+</table>
+```
+
+#### Bad example - calendar grid with partial semantics:
+
+The following example is a date picker or calendar grid.
+
+```html
+<div role="grid">
+  <div role="columnheader">Sun</div>
+  <div role="columnheader">Mon</div>
+  <div role="columnheader">Tue</div>
+  <div role="columnheader">Wed</div>
+  <div role="columnheader">Thu</div>
+  <div role="columnheader">Fri</div>
+  <div role="columnheader">Sat</div>
+  <button role="gridcell" tabindex="-1" aria-label="Sunday, June 1, 2025">1</button>
+  <button role="gridcell" tabindex="-1" aria-label="Monday, June 2, 2025">2</button>
+  <button role="gridcell" tabindex="-1" aria-label="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="Monday, June 9, 2025">9</button>
+  <button role="gridcell" tabindex="-1" aria-label="Tuesday, June 10, 2025">10</button>
+  <button role="gridcell" tabindex="-1" aria-label="Wednesday, June 11, 2025">11</button>
+  <button role="gridcell" tabindex="-1" aria-label="Thursday, June 12, 2025">12</button>
+  <button role="gridcell" tabindex="-1" aria-label="Friday, June 13, 2025">13</button>
+  <button role="gridcell" tabindex="-1" aria-label="Saturday, June 14, 2025">14</button>
+  <button role="gridcell" tabindex="-1" aria-label="Sunday, June 15, 2025">15</button>
+  <button role="gridcell" tabindex="-1" aria-label="Monday, June 16, 2025">16</button>
+  <button role="gridcell" tabindex="-1" aria-label="Tuesday, June 17, 2025">17</button>
+  <button role="gridcell" tabindex="-1" aria-label="Wednesday, June 18, 2025">18</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="Saturday, June 21, 2025">21</button>
+  <button role="gridcell" tabindex="-1" aria-label="Sunday, June 22, 2025">22</button>
+  <button role="gridcell" tabindex="-1" aria-label="Monday, June 23, 2025">23</button>
+  <button role="gridcell" tabindex="-1" aria-label="Tuesday, June 24, 2025" aria-current="date">24</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.

+
+# Custom Agent File Guidelines
+
+Instructions for creating effective and maintainable custom agent files that provide specialized expertise for specific development tasks in GitHub Copilot.
+
+## Project Context
+
+- Target audience: Developers creating custom agents for GitHub Copilot
+- File format: Markdown with YAML frontmatter
+- File naming convention: lowercase with hyphens (e.g., `test-specialist.agent.md`)
+- Location: `.github/agents/` directory (repository-level) or `agents/` directory (organization/enterprise-level)
+- Purpose: Define specialized agents with tailored expertise, tools, and instructions for specific tasks
+- Official documentation: https://docs.github.com/en/copilot/how-tos/use-copilot-agents/coding-agent/create-custom-agents
+
+## Required Frontmatter
+
+Every agent file must include YAML frontmatter with the following fields:
+
+```yaml
+---
+description: 'Brief description of the agent purpose and capabilities'
+name: 'Agent Display Name'
+tools: ['read', 'edit', 'search']
+model: 'Claude Sonnet 4.5'
+target: 'vscode'
+infer: true
+---
+```
+
+### Core Frontmatter Properties
+
+#### **description** (REQUIRED)
+- Single-quoted string, clearly stating the agent's purpose and domain expertise
+- Should be concise (50-150 characters) and actionable
+- Example: `'Focuses on test coverage, quality, and testing best practices'`
+
+#### **name** (OPTIONAL)
+- Display name for the agent in the UI
+- If omitted, defaults to filename (without `.md` or `.agent.md`)
+- Use title case and be descriptive
+- Example: `'Testing Specialist'`
+
+#### **tools** (OPTIONAL)
+- List of tool names or aliases the agent can use
+- Supports comma-separated string or YAML array format
+- If omitted, agent has access to all available tools
+- See "Tool Configuration" section below for details
+
+#### **model** (STRONGLY RECOMMENDED)
+- Specifies which AI model the agent should use
+- Supported in VS Code, JetBrains IDEs, Eclipse, and Xcode
+- Example: `'Claude Sonnet 4.5'`, `'gpt-4'`, `'gpt-4o'`
+- Choose based on agent complexity and required capabilities
+
+#### **target** (OPTIONAL)
+- Specifies target environment: `'vscode'` or `'github-copilot'`
+- If omitted, agent is available in both environments
+- Use when agent has environment-specific features
+
+#### **infer** (OPTIONAL)
+- Boolean controlling whether Copilot can automatically use this agent based on context
+- Default: `true` if omitted
+- Set to `false` to require manual agent selection
+
+#### **metadata** (OPTIONAL, GitHub.com only)
+- Object with name-value pairs for agent annotation
+- Example: `metadata: { category: 'testing', version: '1.0' }`
+- Not supported in VS Code
+
+#### **mcp-servers** (OPTIONAL, Organization/Enterprise only)
+- Configure MCP servers available only to this agent
+- Only supported for organization/enterprise level agents
+- See "MCP Server Configuration" section below
+
+## Tool Configuration
+
+### Tool Specification Strategies
+
+**Enable all tools** (default):
+```yaml
+# Omit tools property entirely, or use:
+tools: ['*']
+```
+
+**Enable specific tools**:
+```yaml
+tools: ['read', 'edit', 'search', 'execute']
+```
+
+**Enable MCP server tools**:
+```yaml
+tools: ['read', 'edit', 'github/*', 'playwright/navigate']
+```
+
+**Disable all tools**:
+```yaml
+tools: []
+```
+
+### Standard Tool Aliases
+
+All aliases are case-insensitive:
+
+| Alias | Alternative Names | Category | Description |
+|-------|------------------|----------|-------------|
+| `execute` | shell, Bash, powershell | Shell execution | Execute commands in appropriate shell |
+| `read` | Read, NotebookRead, view | File reading | Read file contents |
+| `edit` | Edit, MultiEdit, Write, NotebookEdit | File editing | Edit and modify files |
+| `search` | Grep, Glob, search | Code search | Search for files or text in files |
+| `agent` | custom-agent, Task | Agent invocation | Invoke other custom agents |
+| `web` | WebSearch, WebFetch | Web access | Fetch web content and search |
+| `todo` | TodoWrite | Task management | Create and manage task lists (VS Code only) |
+
+### Built-in MCP Server Tools
+
+**GitHub MCP Server**:
+```yaml
+tools: ['github/*']  # All GitHub tools
+tools: ['github/get_file_contents', 'github/search_repositories']  # Specific tools
+```
+- All read-only tools available by default
+- Token scoped to source repository
+
+**Playwright MCP Server**:
+```yaml
+tools: ['playwright/*']  # All Playwright tools
+tools: ['playwright/navigate', 'playwright/screenshot']  # Specific tools
+```
+- Configured to access localhost only
+- Useful for browser automation and testing
+
+### Tool Selection Best Practices
+
+- **Principle of Least Privilege**: Only enable tools necessary for the agent's purpose
+- **Security**: Limit `execute` access unless explicitly required
+- **Focus**: Fewer tools = clearer agent purpose and better performance
+- **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
+
+### ⚠️ Tool Availability Requirement
+
+**Critical**: If a sub-agent requires specific tools (e.g., `edit`, `execute`, `search`), the orchestrator must include those tools in its own `tools` list. Sub-agents cannot access tools that aren't available to their parent orchestrator.
+
+**Example**:
+```yaml
+# If your sub-agents need to edit files, execute commands, or search code
+tools: ['read', 'edit', 'search', 'execute', 'agent']
+```
+
+The orchestrator's tool permissions act as a ceiling for all invoked sub-agents. Plan your tool list carefully to ensure all sub-agents have the tools they need.
+
+### ⚠️ Important Limitation
+
+**Sub-agent orchestration is NOT suitable for large-scale data processing.** Avoid using `runSubagent` when:
+- Processing hundreds or thousands of files
+- Handling large datasets
+- Performing bulk transformations on big codebases
+- Orchestrating more than 5-10 sequential steps
+
+Each sub-agent call adds latency and context overhead. For high-volume processing, implement logic directly in a single agent instead. Use orchestration only for coordinating specialized tasks on focused, manageable datasets.
+
+## 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.
+

+
+### GitHub.com (Coding Agent)
+- ✅ Fully supports all standard frontmatter properties
+- ✅ Repository and org/enterprise level agents
+- ✅ MCP server configuration (org/enterprise)
+- ❌ Does not support `model`, `argument-hint`, `handoffs` properties
+
+### VS Code / JetBrains / Eclipse / Xcode
+- ✅ Supports `model` property for AI model selection
+- ✅ Supports `argument-hint` and `handoffs` properties
+- ✅ User profile and workspace-level agents
+- ❌ Cannot configure MCP servers at repository level
+- ⚠️ Some properties may behave differently
+
+When creating agents for multiple environments, focus on common properties and test in all target environments. Use `target` property to create environment-specific agents when necessary.

+
+# 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

+   - Check Go docs for migration path
+   - Example: `filepath.HasPrefix` → use `strings.HasPrefix` with cleaned paths
+
+3. **"This value is never used" (SA4006)**
+   - Fix: Remove unused assignment or use the value
+   - Common in test setup code
+
+4. **"Should replace if statement with..." (S10xx)**
+   - Fix: Apply suggested simplification
+   - These improve readability and performance

+5. **Emergency bypass (use sparingly):**
+   - `git commit --no-verify -m "Emergency hotfix"`
+   - **MUST** create follow-up issue to fix staticcheck errors
+   - Only for production incidents

 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`

+        - **Zero high/critical (error-level) findings allowed**
+        - 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`
+
+3. **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. **Coverage Testing** (MANDATORY - Non-negotiable):
+4. **Staticcheck BLOCKING Validation**: Pre-commit hooks automatically run fast linters including staticcheck.
+    - **CRITICAL:** Staticcheck errors are BLOCKING - you MUST fix them before commit succeeds.
+    - Manual verification: Run VS Code task "Lint: Staticcheck (Fast)" or `make lint-fast`
+    - To check only staticcheck: `make lint-staticcheck-only`
+    - Test files (`_test.go`) are excluded from staticcheck (matches CI behavior)
+    - If pre-commit fails: Fix the reported issues, then retry commit
+    - **Do NOT** use `--no-verify` to bypass this check unless emergency hotfix
+
+5. **Coverage Testing** (MANDATORY - Non-negotiable):
+    - **MANDATORY**: Patch coverage must cover 100% of modified lines (Codecov Patch view must be green). If patch coverage fails, add targeted tests for the missing patch line ranges.
     - **Backend Changes**: Run the VS Code task "Test: Backend with Coverage" or execute `scripts/go-test-coverage.sh`.
         - Minimum coverage: 85% (set via `CHARON_MIN_COVERAGE` or `CPM_MIN_COVERAGE`).

+# 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
+    - 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
+3. **Error Handling**: Preferred error handling patterns
+4. **Dependencies**: How to manage and document dependencies
+5. **Comments and Documentation**: When and how to document code
+6. **Version Information**: Target language/framework versions
+
+## Patterns to Follow
+
+### Bullet Points and Lists
+
+```markdown
+## Security Best Practices
+
+- Always validate user input before processing
+- Use parameterized queries to prevent SQL injection
+- Store secrets in environment variables, never in code
+- Implement proper authentication and authorization
+- Enable HTTPS for all production endpoints
+```
+
+### Tables for Structured Information
+
+```markdown
+## Common Issues
+
+| Issue            | Solution            | Example                       |
+| ---------------- | ------------------- | ----------------------------- |
+| Magic numbers    | Use named constants | `const MAX_RETRIES = 3`       |
+| Deep nesting     | Extract functions   | Refactor nested if statements |
+| Hardcoded values | Use configuration   | Store API URLs in config      |
+```
+
+### Code Comparison
+
+```markdown
+### Good Example - Using TypeScript interfaces
+\`\`\`typescript
+interface User {
+  id: string;
+  name: string;
+  email: string;
+}
+
+function getUser(id: string): User {
+  // Implementation
+}
+\`\`\`
+
+### Bad Example - Using any type
+\`\`\`typescript
+function getUser(id: any): any {
+  // Loses type safety
+}
+\`\`\`
+```
+
+### Conditional Guidance
+
+```markdown
+## Framework Selection
+
+- **For small projects**: Use Minimal API approach
+- **For large projects**: Use controller-based architecture with clear separation
+- **For microservices**: Consider domain-driven design patterns
+```
+
+## Patterns to Avoid
+
+- **Overly verbose explanations**: Keep it concise and scannable
+- **Outdated information**: Always reference current versions and practices
+- **Ambiguous guidelines**: Be specific about what to do or avoid
+- **Missing examples**: Abstract rules without concrete code examples
+- **Contradictory advice**: Ensure consistency throughout the file
+- **Copy-paste from documentation**: Add value by distilling and contextualizing
+
+## Testing Your Instructions
+
+Before finalizing instruction files:
+
+1. **Test with Copilot**: Try the instructions with actual prompts in VS Code
+2. **Verify Examples**: Ensure code examples are correct and run without errors
+3. **Check Glob Patterns**: Confirm `applyTo` patterns match intended files
+
+## Example Structure
+
+Here's a minimal example structure for a new instruction file:
+
+```markdown

+# 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

+
+## 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.

+# 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

+## 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

+# 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)

+- [ ] 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

 -   **Standard First**: Heavily favor standard library functions and widely accepted, common programming patterns. Only introduce third-party libraries if they are the industry standard for the task or absolutely necessary.
 -   **Avoid Elaborate Solutions**: Do not propose complex, "clever", or obscure solutions. Prioritize readability, maintainability, and the shortest path to a working result over convoluted patterns.
 -   **Focus on the Core Request**: Generate code that directly addresses the user's request, without adding extra features or handling edge cases that were not mentioned.

+
+# 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 functions correctly end-to-end.
+
+* **Run Playwright E2E Tests**: Execute `npx playwright test --project=chromium` from the project root.
+* **Why First**: If the application is broken at the E2E level, unit tests may need updates. Playwright catches integration issues early.
+* **Base URL**: Tests use `PLAYWRIGHT_BASE_URL` env var or default from `playwright.config.js` (Tailscale IP: `http://100.98.12.109:8080`).
+* **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 +26,5 @@ 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.

+# 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.

+Create time-boxed technical spike documents for researching critical questions that must be answered before development can proceed. Each spike focuses on a specific technical decision with clear deliverables and timelines.
+
+## Document Structure
+
+Create individual files in `${input:FolderPath|docs/spikes}` directory. Name each file using the pattern: `[category]-[short-description]-spike.md` (e.g., `api-copilot-integration-spike.md`, `performance-realtime-audio-spike.md`).
+
+```md

+# 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 NOT** suppress errors without addressing the root cause
+- **DO NOT** apply quick hacks—always explain trade-offs if a temporary fix is needed
+- **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
+SELECT u.name
+FROM users u
+INNER JOIN orders o ON u.id = o.user_id
+GROUP BY u.name;
+```
+
+### Function Misuse in WHERE Clauses
+```sql
+-- ❌ BAD: Functions prevent index usage
+SELECT * FROM orders
+WHERE YEAR(order_date) = 2024;
+
+-- ✅ GOOD: Range conditions use indexes
+SELECT * FROM orders
+WHERE order_date >= '2024-01-01'
+  AND order_date < '2025-01-01';
+```

+# SQL Performance Optimization Assistant
+
+Expert SQL performance optimization for ${selection} (or entire project if no selection). Focus on universal SQL optimization techniques that work across MySQL, PostgreSQL, SQL Server, Oracle, and other SQL databases.
+
+## 🎯 Core Optimization Areas
+
+### Query Performance Analysis
+```sql
+-- ❌ BAD: Inefficient query patterns
+SELECT * FROM orders o
+WHERE YEAR(o.created_at) = 2024
+  AND o.customer_id IN (
+      SELECT c.id FROM customers c WHERE c.status = 'active'
+  );
+
+-- ✅ GOOD: Optimized query with proper indexing hints
+SELECT o.id, o.customer_id, o.total_amount, o.created_at
+FROM orders o
+INNER JOIN customers c ON o.customer_id = c.id
+WHERE o.created_at >= '2024-01-01'
+  AND o.created_at < '2025-01-01'
+  AND c.status = 'active';
+
+-- Required indexes:
+-- CREATE INDEX idx_orders_created_at ON orders(created_at);
+-- CREATE INDEX idx_customers_status ON customers(status);
+-- CREATE INDEX idx_orders_customer_id ON orders(customer_id);
+```
+
+### Index Strategy Optimization
+```sql
+-- ❌ BAD: Poor indexing strategy
+CREATE INDEX idx_user_data ON users(email, first_name, last_name, created_at);
+
+-- ✅ GOOD: Optimized composite indexing
+-- For queries filtering by email first, then sorting by created_at
+CREATE INDEX idx_users_email_created ON users(email, created_at);
+
+-- For full-text name searches
+CREATE INDEX idx_users_name ON users(last_name, first_name);
+
+-- For user status queries
+CREATE INDEX idx_users_status_created ON users(status, created_at)
+WHERE status IS NOT NULL;
+```
+
+### Subquery Optimization
+```sql
+-- ❌ BAD: Correlated subquery
+SELECT p.product_name, p.price
+FROM products p
+WHERE p.price > (
+    SELECT AVG(price)
+    FROM products p2
+    WHERE p2.category_id = p.category_id
+);
+
+-- ✅ GOOD: Window function approach
+SELECT product_name, price
+FROM (
+    SELECT product_name, price,
+           AVG(price) OVER (PARTITION BY category_id) as avg_category_price
+    FROM products
+) ranked
+WHERE price > avg_category_price;
+```
+
+## 📊 Performance Tuning Techniques
+
+### JOIN Optimization
+```sql
+-- ❌ BAD: Inefficient JOIN order and conditions
+SELECT o.*, c.name, p.product_name
+FROM orders o
+LEFT JOIN customers c ON o.customer_id = c.id
+LEFT JOIN order_items oi ON o.id = oi.order_id
+LEFT JOIN products p ON oi.product_id = p.id
+WHERE o.created_at > '2024-01-01'
+  AND c.status = 'active';
+
+-- ✅ GOOD: Optimized JOIN with filtering
+SELECT o.id, o.total_amount, c.name, p.product_name
+FROM orders o
+INNER JOIN customers c ON o.customer_id = c.id AND c.status = 'active'
+INNER JOIN order_items oi ON o.id = oi.order_id
+INNER JOIN products p ON oi.product_id = p.id
+WHERE o.created_at > '2024-01-01';
+```
+
+### Pagination Optimization
+```sql
+-- ❌ BAD: OFFSET-based pagination (slow for large offsets)
+SELECT * FROM products
+ORDER BY created_at DESC
+LIMIT 20 OFFSET 10000;
+
+-- ✅ GOOD: Cursor-based pagination
+SELECT * FROM products
+WHERE created_at < '2024-06-15 10:30:00'
+ORDER BY created_at DESC
+LIMIT 20;
+
+-- Or using ID-based cursor
+SELECT * FROM products
+WHERE id > 1000
+ORDER BY id
+LIMIT 20;
+```
+
+### Aggregation Optimization
+```sql
+-- ❌ BAD: Multiple separate aggregation queries
+SELECT COUNT(*) FROM orders WHERE status = 'pending';
+SELECT COUNT(*) FROM orders WHERE status = 'shipped';
+SELECT COUNT(*) FROM orders WHERE status = 'delivered';
+
+-- ✅ GOOD: Single query with conditional aggregation
+SELECT
+    COUNT(CASE WHEN status = 'pending' THEN 1 END) as pending_count,
+    COUNT(CASE WHEN status = 'shipped' THEN 1 END) as shipped_count,
+    COUNT(CASE WHEN status = 'delivered' THEN 1 END) as delivered_count
+FROM orders;
+```
+
+## 🔍 Query Anti-Patterns
+
+### SELECT Performance Issues
+```sql
+-- ❌ BAD: SELECT * anti-pattern
+SELECT * FROM large_table lt
+JOIN another_table at ON lt.id = at.ref_id;
+
+-- ✅ GOOD: Explicit column selection
+SELECT lt.id, lt.name, at.value
+FROM large_table lt
+JOIN another_table at ON lt.id = at.ref_id;
+```
+
+### WHERE Clause Optimization
+```sql
+-- ❌ BAD: Function calls in WHERE clause
+SELECT * FROM orders
+WHERE UPPER(customer_email) = 'JOHN@EXAMPLE.COM';
+
+-- ✅ GOOD: Index-friendly WHERE clause
+SELECT * FROM orders
+WHERE customer_email = 'john@example.com';
+-- Consider: CREATE INDEX idx_orders_email ON orders(LOWER(customer_email));
+```
+
+### OR vs UNION Optimization
+```sql
+-- ❌ BAD: Complex OR conditions
+SELECT * FROM products
+WHERE (category = 'electronics' AND price < 1000)
+   OR (category = 'books' AND price < 50);
+
+-- ✅ GOOD: UNION approach for better optimization
+SELECT * FROM products WHERE category = 'electronics' AND price < 1000
+UNION ALL
+SELECT * FROM products WHERE category = 'books' AND price < 50;
+```
+
+## 📈 Database-Agnostic Optimization
+
+### Batch Operations
+```sql
+-- ❌ BAD: Row-by-row operations
+INSERT INTO products (name, price) VALUES ('Product 1', 10.00);
+INSERT INTO products (name, price) VALUES ('Product 2', 15.00);
+INSERT INTO products (name, price) VALUES ('Product 3', 20.00);
+
+-- ✅ GOOD: Batch insert
+INSERT INTO products (name, price) VALUES
+('Product 1', 10.00),
+('Product 2', 15.00),
+('Product 3', 20.00);
+```
+
+### Temporary Table Usage
+```sql
+-- ✅ GOOD: Using temporary tables for complex operations
+CREATE TEMPORARY TABLE temp_calculations AS
+SELECT customer_id,
+       SUM(total_amount) as total_spent,
+       COUNT(*) as order_count
+FROM orders
+WHERE created_at >= '2024-01-01'
+GROUP BY customer_id;
+
+-- Use the temp table for further calculations
+SELECT c.name, tc.total_spent, tc.order_count
+FROM temp_calculations tc
+JOIN customers c ON tc.customer_id = c.id
+WHERE tc.total_spent > 1000;
+```
+
+## 🛠️ Index Management
+
+### Index Design Principles
+```sql
+-- ✅ GOOD: Covering index design
+CREATE INDEX idx_orders_covering
+ON orders(customer_id, created_at)
+INCLUDE (total_amount, status);  -- SQL Server syntax
+-- Or: CREATE INDEX idx_orders_covering ON orders(customer_id, created_at, total_amount, status); -- Other databases
+```
+
+### Partial Index Strategy
+```sql
+-- ✅ GOOD: Partial indexes for specific conditions
+CREATE INDEX idx_orders_active
+ON orders(created_at)
+WHERE status IN ('pending', 'processing');
+```
+
+## 📊 Performance Monitoring Queries
+
+### Query Performance Analysis
+```sql
+-- Generic approach to identify slow queries
+-- (Specific syntax varies by database)
+
+-- For MySQL:
+SELECT query_time, lock_time, rows_sent, rows_examined, sql_text
+FROM mysql.slow_log
+ORDER BY query_time DESC;
+
+-- For PostgreSQL:
+SELECT query, calls, total_time, mean_time
+FROM pg_stat_statements
+ORDER BY total_time DESC;
+
+-- For SQL Server:
+SELECT
+    qs.total_elapsed_time/qs.execution_count as avg_elapsed_time,
+    qs.execution_count,
+    SUBSTRING(qt.text, (qs.statement_start_offset/2)+1,
+        ((CASE qs.statement_end_offset WHEN -1 THEN DATALENGTH(qt.text)
+        ELSE qs.statement_end_offset END - qs.statement_start_offset)/2)+1) as query_text
+FROM sys.dm_exec_query_stats qs
+CROSS APPLY sys.dm_exec_sql_text(qs.sql_handle) qt
+ORDER BY avg_elapsed_time DESC;
+```
+

+
+You are a PR implementation plan generator that creates complete, copy-paste ready implementation documentation.
+
+Your SOLE responsibility is to:
+1. Accept a complete PR plan (plan.md in plans/{feature-name}/)
+2. Extract all implementation steps from the plan
+3. Generate comprehensive step documentation with complete code
+4. Save plan to: `plans/{feature-name}/implementation.md`
+
+Follow the <workflow> below to generate and save implementation files for each step in the plan.
+
+<workflow>
+
+## Step 1: Parse Plan & Research Codebase
+
+1. Read the plan.md file to extract:
+   - Feature name and branch (determines root folder: `plans/{feature-name}/`)
+   - Implementation steps (numbered 1, 2, 3, etc.)
+   - Files affected by each step
+2. Run comprehensive research ONE TIME using <research_task>. Use `runSubagent` to execute. Do NOT pause.
+3. Once research returns, proceed to Step 2 (file generation).
+
+## Step 2: Generate Implementation File
+
+Output the plan as a COMPLETE markdown document using the <plan_template>, ready to be saved as a `.md` file.
+
+The plan MUST include:
+- Complete, copy-paste ready code blocks with ZERO modifications needed
+- Exact file paths appropriate to the project structure
+- Markdown checkboxes for EVERY action item
+- Specific, observable, testable verification points
+- NO ambiguity - every instruction is concrete
+- NO "decide for yourself" moments - all decisions made based on research

+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:

+# 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.

+
+## Local Asset Discovery Process
+
+1. **Scan Asset Directories**:
+   - List all `*.prompt.md` files in `prompts/` directory
+   - List all `*.instructions.md` files in `instructions/` directory
+   - List all `*.agent.md` files in `agents/` directory
+
+2. **Extract Asset Metadata**: For each discovered file, read YAML front matter to extract:
+   - `description` - Primary purpose and functionality
+   - `tools` - Required tools and capabilities
+   - `mode` - Operating mode (for prompts)
+   - `model` - Specific model requirements (for chat modes)
+
+3. **Build Asset Inventory**: Create comprehensive map of existing capabilities organized by:
+   - **Technology Focus**: Programming languages, frameworks, platforms
+   - **Workflow Type**: Development, testing, deployment, documentation, planning
+   - **Specialization Level**: General purpose vs. specialized expert modes
+
+4. **Identify Coverage Gaps**: Compare existing assets against:
+   - Repository technology stack requirements
+   - Development workflow needs indicated by chat history
+   - Industry best practices for identified project types
+   - Missing expertise areas (security, performance, architecture, etc.)
+
+## Collection Asset Download Process

+   - 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.

+# 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 |
+| CWE-502 | Deserialization | Go, JS |
+| CWE-611 | XXE Injection | Go |
+| CWE-640 | Email Injection | Go |
+| CWE-798 | Hardcoded Credentials | Go, JS |
+| CWE-918 | SSRF | 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)

+# .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:

+
+### 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 v0.85.0 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 | ✅ |

+## 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 v0.85.0
+```
+
+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 v0.85.0
+```
+
+## 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

+# 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"
+```
+

+## 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/..." },
+      "metadata": {
+        "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

+
+- [security-verify-sbom](./security-verify-sbom.SKILL.md) - Verify SBOM and scan vulnerabilities
+- [security-sign-cosign](./security-sign-cosign.SKILL.md) - Sign artifacts with Cosign
+
+## 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
+- Use SLSA-compliant build platforms (GitHub Actions, Cloud Build, etc.)

+# 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
+

+- [security-sign-cosign](./security-sign-cosign.SKILL.md) - Sign artifacts with Cosign
+- [security-slsa-provenance](./security-slsa-provenance.SKILL.md) - Generate SLSA provenance
+- [security-scan-trivy](./security-scan-trivy.SKILL.md) - Alternative vulnerability scanner
+
+## 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

+# Test E2E Playwright
+
+## Overview
+
+Executes Playwright end-to-end tests against the Charon application. This skill supports browser selection, headed mode for debugging, and test filtering by name pattern.
+
+The skill runs non-interactively by default (HTML report does not auto-open), making it suitable for CI/CD pipelines and automated testing scenarios.
+
+## Prerequisites
+
+- Node.js 18.0 or higher installed and in PATH
+- Playwright browsers installed (`npx playwright install`)
+- Charon application running (default: `http://localhost:8080`)
+- Test files in `tests/` directory
+
+## Usage
+
+### Basic Usage
+
+Run E2E tests with default settings (Chromium, headless):
+
+```bash
+.github/skills/scripts/skill-runner.sh test-e2e-playwright
+```
+
+### Browser Selection
+
+Run tests in a specific browser:
+
+```bash
+# Chromium (default)
+.github/skills/scripts/skill-runner.sh test-e2e-playwright --project=chromium
+
+# Firefox
+.github/skills/scripts/skill-runner.sh test-e2e-playwright --project=firefox
+
+# WebKit (Safari)
+.github/skills/scripts/skill-runner.sh test-e2e-playwright --project=webkit
+
+# All browsers
+.github/skills/scripts/skill-runner.sh test-e2e-playwright --project=all
+```
+
+### Headed Mode (Debugging)
+
+Run tests with a visible browser window:
+
+```bash
+.github/skills/scripts/skill-runner.sh test-e2e-playwright --headed
+```
+
+### Filter Tests
+
+Run only tests matching a pattern:
+
+```bash
+# Run tests with "login" in the title
+.github/skills/scripts/skill-runner.sh test-e2e-playwright --grep="login"
+
+# Run tests with "DNS" in the title
+.github/skills/scripts/skill-runner.sh test-e2e-playwright --grep="DNS"
+```
+
+### Combined Options
+
+```bash
+.github/skills/scripts/skill-runner.sh test-e2e-playwright --project=firefox --headed --grep="dashboard"
+```
+
+### CI/CD Integration
+
+For use in GitHub Actions or other CI/CD pipelines:
+
+```yaml
+- name: Run E2E Tests
+  run: .github/skills/scripts/skill-runner.sh test-e2e-playwright
+  env:
+    PLAYWRIGHT_BASE_URL: http://localhost:8080
+    CI: true
+```
+
+## Parameters
+
+| Parameter | Type | Required | Default | Description |
+|-----------|------|----------|---------|-------------|
+| project   | string | No | chromium | Browser project: chromium, firefox, webkit, all |
+| headed    | boolean | No | false | Run with visible browser window |
+| grep      | string | No | "" | Filter tests by title pattern (regex) |
+
+## Environment Variables
+
+| Variable | Required | Default | Description |
+|----------|----------|---------|-------------|
+| PLAYWRIGHT_BASE_URL | No | http://localhost:8080 | Application URL to test against |
+| PLAYWRIGHT_HTML_OPEN | No | never | HTML report auto-open behavior |
+| CI | No | "" | Set to "true" for CI environment behavior |
+
+## Outputs
+
+### Success Exit Code
+- **0**: All tests passed
+
+### Error Exit Codes
+- **1**: One or more tests failed
+- **Non-zero**: Configuration or execution error
+
+### Output Directories
+- **playwright-report/**: HTML report with test results and traces
+- **test-results/**: Test artifacts, screenshots, and trace files
+
+## Viewing the Report
+
+After test execution, view the HTML report using VS Code Simple Browser:
+
+### Method 1: Start Report Server
+
+```bash
+npx playwright show-report --port 9323
+```
+
+Then open in VS Code Simple Browser: `http://127.0.0.1:9323`
+
+### Method 2: VS Code Task
+
+Use the VS Code task "Test: E2E Playwright - View Report" to start the report server as a background task, then open `http://127.0.0.1:9323` in Simple Browser.
+
+### Method 3: Direct File Access
+
+Open `playwright-report/index.html` directly in a browser.
+
+## Examples
+
+### Example 1: Quick Smoke Test
+
+```bash
+.github/skills/scripts/skill-runner.sh test-e2e-playwright --grep="smoke"
+```
+
+### Example 2: Debug Failing Test
+
+```bash
+.github/skills/scripts/skill-runner.sh test-e2e-playwright --headed --grep="failing-test-name"
+```
+
+### Example 3: Cross-Browser Validation
+
+```bash
+.github/skills/scripts/skill-runner.sh test-e2e-playwright --project=all
+```
+
+## Test Structure
+
+Tests are located in the `tests/` directory and follow Playwright conventions:
+
+```
+tests/
+├── auth.setup.ts          # Authentication setup (runs first)
+├── dashboard.spec.ts      # Dashboard tests
+├── dns-records.spec.ts    # DNS management tests
+├── login.spec.ts          # Login flow tests
+└── ...
+```
+
+## Error Handling
+
+### Common Errors
+
+#### Error: Target page, context or browser has been closed
+**Solution**: Ensure the application is running at the configured base URL
+
+#### Error: page.goto: net::ERR_CONNECTION_REFUSED
+**Solution**: Start the Charon application before running tests
+
+#### Error: browserType.launch: Executable doesn't exist
+**Solution**: Run `npx playwright install` to install browser binaries
+
+## Related Skills
+
+- test-frontend-unit - Frontend unit tests with Vitest
+- docker-start-dev - Start development environment
+- integration-test-all - Run all integration tests
+
+## Notes
+
+- **Authentication**: Tests use stored auth state from `playwright/.auth/user.json`
+- **Parallelization**: Tests run in parallel locally, sequential in CI
+- **Retries**: CI automatically retries failed tests twice
+- **Traces**: Traces are collected on first retry for debugging
+- **Report**: HTML report is generated at `playwright-report/index.html`

+      # Critical Fix: Use exact tag from metadata instead of manual reconstruction

+      # - Case sensitivity variations (owner name normalization)
+      # - Tag format differences in Buildx internal behavior
+      # - Registry prefix inconsistencies
+      #
+      # SOLUTION: Extract the first tag from metadata output (which is the PR tag)
+      # and use it directly with docker save. This guarantees we reference the
+      # exact image that was loaded into the local Docker daemon.
+      #
+      # VALIDATION: Added defensive checks to fail fast with diagnostics if:

+  # CVE-2026-22184: zlib Global Buffer Overflow in untgz utility
+  # Severity: CRITICAL
+  # Package: zlib 1.3.1-r2 (Alpine Linux base image)
+  # Status: No upstream fix available as of 2026-01-16
+  #
+  # Vulnerability Details:
+  # - Global buffer overflow in TGZfname() function
+  # - Unbounded strcpy() allows attacker-controlled archive names
+  # - Can lead to memory corruption, DoS, potential RCE
+  #
+  # Risk Assessment: ACCEPTED (Low exploitability in Charon context)
+  # - Charon does not use untgz utility directly
+  # - No untrusted tar archive processing in application code
+  # - Attack surface limited to OS-level utilities
+  # - Multiple layers of containerization and isolation
+  #
+  # Mitigation:
+  # - Monitor Alpine Linux security feed daily for zlib patches
+  # - Container runs with minimal privileges (no-new-privileges)
+  # - Read-only filesystem where possible
+  # - Network isolation via Docker networks
+  #
+  # Review:
+  # - Daily checks for Alpine security updates
+  # - Automatic re-scan via CI/CD on every commit
+  # - Manual review scheduled for 2026-01-23 (7 days)
+  #
+  # Removal Criteria:
+  # - Alpine releases zlib 1.3.1-r3 or higher with CVE fix
+  # - OR upstream zlib project releases patched version
+  # - Remove this suppression immediately after fix available
+  #
+  # References:

+    package:
+      name: zlib
+      version: "1.3.1-r2"
+      type: apk  # Alpine package
+    reason: |
+      CRITICAL buffer overflow in untgz utility. No fix available from Alpine
+      as of 2026-01-16. Risk accepted: Charon does not directly use untgz or
