+# Verify Implementation
+
+## Pre-computed Context
+
+**Changed Files:**
+!`git diff --name-only HEAD~5 2>/dev/null | head -20 || git diff --name-only --cached`
+
+**Recent Commits:**
+!`git log --oneline -5`
+
+**Package Scripts:**
+!`cat package.json 2>/dev/null | grep -A 20 '"scripts"' | head -25 || echo "No package.json"`
+
+**Test Files:**
+!`find . -name "*.test.*" -o -name "*.spec.*" 2>/dev/null | head -10 || echo "No test files found"`
+
+---
+
+## Instructions
+
+You are performing end-to-end verification of recent changes. This is a thorough check before committing or creating a PR.
+
+### Verification Checklist
+
+#### 1. Static Analysis
+Run available linters and type checkers:
+
+```bash
+# TypeScript
+npx tsc --noEmit 2>/dev/null || echo "No TypeScript"
+
+# ESLint
+npx eslint . --ext .ts,.tsx,.js,.jsx 2>/dev/null || echo "No ESLint"
+
+# For Python
+python -m mypy . 2>/dev/null || echo "No mypy"
+ruff check . 2>/dev/null || echo "No ruff"
+```
+
+#### 2. Unit Tests
+Run tests for changed files:
+
+```bash
+# Jest
+npx jest --passWithNoTests 2>/dev/null || echo "No Jest"
+
+# Vitest
+npx vitest run 2>/dev/null || echo "No Vitest"
+
+# pytest
+pytest 2>/dev/null || echo "No pytest"
+```
+
+#### 3. Build Verification
+Ensure the project builds:
+
+```bash
+npm run build 2>/dev/null || yarn build 2>/dev/null || echo "No build script"
+```
+
+#### 4. Manual Code Review
+For each changed file, verify:
+- [ ] No hardcoded secrets or credentials
+- [ ] Error handling is present where needed
+- [ ] No obvious security vulnerabilities (SQL injection, XSS, etc.)
+- [ ] Code follows existing patterns in the codebase
+
+#### 5. Integration Check
+If the scope argument is provided, focus verification on that area:
+- Read related files
+- Trace the data flow
+- Verify edge cases are handled
+
+### Report
+
+After verification, provide a summary:
+
+```
+## Verification Report
+
+### Passed
+- [x] TypeScript compilation
+- [x] Unit tests (X passed)
+- [x] Build successful
+
+### Issues Found
+- [ ] Issue 1: description
+- [ ] Issue 2: description
+
+### Recommendations
+- Suggestion 1
+- Suggestion 2
+```

+
+## Subagent Mode
+
+For comprehensive verification, this command can spawn a verification subagent:
+
+```
+Use the Task tool with subagent_type="general-purpose" to:
+1. Read all changed files
+2. Run all available test suites
+3. Check for common issues
+4. Report findings
+```
+
+The subagent has access to Bash, Read, Grep, and Glob tools to perform thorough verification.
