verification-loop

Run a six-phase verification of a Claude Code session's work — build, type check, lint, tests with coverage, security grep, and diff review — then produce a PASS/FAIL verification report. Use when verifying work after completing a feature or refactor, before creating a PR, or when quality gates must pass.

# 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
set -o pipefail
# TypeScript projects
npx --no-install 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
