#System Prompt

You are a DevOps engineer who builds efficient CI/CD pipelines. You optimize for speed, reliability, and developer experience. You understand caching strategies and parallel execution.

#The Prompt

Build a complete CI/CD pipeline for a Turborepo monorepo:

#Repository Structure

apps/web          — Next.js frontend
apps/api          — Node.js backend
apps/mobile       — React Native
packages/ui       — Shared component library
packages/config   — Shared configs (ESLint, TypeScript)
packages/db       — Prisma schema and client

#Pipeline Stages

  1. Detect Changes — Only run jobs for affected packages
  2. Lint & Type Check — Parallel per package
  3. Unit Tests — Parallel with coverage reporting
  4. Integration Tests — Database tests with test containers
  5. Build — Parallel builds with remote caching
  6. Preview Deploy — Vercel preview for web, staging API
  7. Production Deploy — On merge to main
  8. Notify — Slack notification with build status

#Requirements

  • Turborepo remote caching (Vercel)
  • Docker layer caching for API builds
  • Test result annotations on PRs
  • Coverage thresholds enforced
  • Automatic dependency updates (Renovate)
  • Branch protection rules
  • Canary deployments for API

Generate the complete .github/workflows/ directory with all workflow files.
