verification-loop
A comprehensive verification system for Claude Code sessions.
Best use case
verification-loop is best used when you need a repeatable AI agent workflow instead of a one-off prompt.
A comprehensive verification system for Claude Code sessions.
Teams using verification-loop should expect a more consistent output, faster repeated execution, less prompt rewriting.
When to use this skill
- You want a reusable workflow that can be run more than once with consistent structure.
When not to use this skill
- You only need a quick one-off answer and do not need a reusable workflow.
- You cannot install or maintain the underlying files, dependencies, or repository context.

# Verification Loop Skill A comprehensive verification system for Claude Code sessions. ## When to Use Invoke this skill: - After completing a feature or significant code change - Before creating a PR - When you want to ensure quality gates pass - After refactoring ## Verification Phases ### Phase 1: Build Verification ```bash # Check if project builds npm run build 2>&1 | tail -20 # OR pnpm build 2>&1 | tail -20 ``` If build fails, STOP and fix before continuing. ### Phase 2: Type Check ```bash # TypeScript projects npx tsc --noEmit 2>&1 | head -30 # Python projects pyright . 2>&1 | head -30 ``` Report all type errors. Fix critical ones before continuing. ### Phase 3: Lint Check ```bash # JavaScript/TypeScript npm run lint 2>&1 | head -30 # Python ruff check . 2>&1 | head -30 ``` ### Phase 4: Test Suite ```bash # Run tests with coverage npm run test -- --coverage 2>&1 | tail -50 # Check coverage threshold # Target: 80% minimum ``` Report: - Total tests: X - Passed: X - Failed: X - Coverage: X% ### Phase 5: Security Scan ```bash # Check for secrets grep -rn "sk-" --include="*.ts" --include="*.js" . 2>/dev/null | head -10 grep -rn "api_key" --include="*.ts" --include="*.js" . 2>/dev/null | head -10 # Check for console.log grep -rn "console.log" --include="*.ts" --include="*.tsx" src/ 2>/dev/null | head -10 ``` ### Phase 6: Diff Review ```bash # Show what changed git diff --stat git diff HEAD~1 --name-only ``` Review each changed file for: - Unintended changes - Missing error handling - Potential edge cases ## Output Format After running all phases, produce a verification report: ``` VERIFICATION REPORT ================== Build: [PASS/FAIL] Types: [PASS/FAIL] (X errors) Lint: [PASS/FAIL] (X warnings) Tests: [PASS/FAIL] (X/Y passed, Z% coverage) Security: [PASS/FAIL] (X issues) Diff: [X files changed] Overall: [READY/NOT READY] for PR Issues to Fix: 1. ... 2. ... ``` ## Continuous Mode For long sessions, run verification every 15 minutes or after major changes: ```markdown Set a mental checkpoint: - After completing each function - After finishing a component - Before moving to next task Run: /verify ``` ## Integration with Hooks This skill complements PostToolUse hooks but provides deeper verification. Hooks catch issues immediately; this skill provides comprehensive review.
