# Deployment
## Rules
- Environment variables: `.env.local` for dev, platform env vars for production — never commit `.env`
- Health check endpoint: `GET /api/health` returns `{ status: "ok" }`
- Preview deployments: every PR gets a preview URL (Vercel/Netlify/Railway)
- Rollback strategy: keep previous deployment ready, one-click rollback
- CI/CD: tests must pass before deploy — never skip
- Domain setup: CNAME for custom domain, SSL auto-provisioned
- Build command: `npm run build` — should complete without errors or warnings
- Output logs: structured JSON logging for production, human-readable for devInstall
Why Use the Deployment Skill?
Without this skill, your AI guesses at deployment patterns. It might hallucinate deprecated APIs, use outdated conventions, or miss best practices entirely. With it, your AI follows a proven ruleset — every suggestion aligns with current standards.
Drop this skill into your project and your AI instantly knows the rules. Better code suggestions, fewer errors, faster shipping.
