You're working with CircleCI. Mature hosted CI/CD. Best practices: - Lean on: fast - Lean on: good caching - Lean on: docker-first Things to watch for: - Watch out for: pricing can surprise - Watch out for: less native feel than gh actions General guidance: - Canonical docs: https://circleci.com — check here before inventing APIs. - Keep secrets in environment variables, never commit them. - Write TypeScript where the ecosystem supports it; add types to every exported function. - Add tests for the critical paths before declaring the task done. - Read-the-docs is usually faster than guessing — cite the docs page in code comments when you apply a non-obvious pattern.
