# CI/CD and Automation ## Overview Automate quality gates so that no change reaches production without passing tests, lint, type checking, and build. CI/CD is the enforcement mechanism for every other skill — it catches what humans and agents miss, and it does so consistently on every single change. ## When to Use - Setting up a new project's CI pipeline - Adding or modifying automated checks - Configuring deployment pipelines - When a change should trigger automated verification - Debugging CI failures ## The Quality Gate Pipeline Every change goes through these gates before merge: ``` Pull Request Opened │ ▼ ┌─────────────────┐ │ LINT CHECK │ eslint, prettier │ ↓ pass │ │ TYPE CHECK │ tsc --noEmit │ ↓ pass │ │ UNIT TESTS │ jest/vitest │ ↓ pass │ │ BUILD │ npm run build │ ↓ pass │ │ INTEGRATION │ API/DB tests │ ↓ pass │ │ E2E (optional) │ Playwright/Cypress │ ↓ pass │ │ SECURITY AUDIT │ npm audit │ ↓ pass │ │ BUNDLE SIZE │ bundlesize check └─────────────────┘ │ ▼ Ready for review ``` **No gate can be skipped.** If lint fails, fix lint — don't disable the rule. If a test fails, fix the code — don't skip the test. ## GitHub Actions Configuration ### Basic CI Pipeline ```yaml # .github/workflows/ci.yml name: CI on: pull_request: branches: [main] push: branches: [main] jobs: quality: runs-on: ubuntu-latest s
