Code Quality Gate

This skill prevents production failures through a 5-stage Quality Gate System.

The 5 Quality Gates

1. Pre-Commit (local): TypeScript, Lint, Format - blocks commit on errors
2. PR-Check (GitHub Actions): Unit Tests, Build - blocks merge on errors
3. Preview Deploy: Vercel/Netlify Preview URL for visual review
4. E2E Tests: Playwright against Preview, Lighthouse performance audit
5. Production Deploy: Only when ALL gates pass

Critical Rules

• CRITICAL: NEVER use continue-on-error: true for TypeScript checks in GitHub Actions!
• Husky Setup: npm install -D husky lint-staged && npx husky init
• Rollback: vercel rollback

Example: Pre-Commit Hook (.husky/pre-commit)
