Use at the start of, and throughout, any work that builds or finishes a full software project with claude-engineer. Establishes the project lifecycle, the iron laws, and which skill to invoke at each stage. Auto-injected at session start.

Use when building or structuring a Python backend on FastAPI + SQLAlchemy 2.0 (async) + Alembic + Pydantic v2. Provides the opinionated project layout, the standard kit (auth, async jobs, caching, storage, observability), and best practices.
Use near the end of a project to generate CI and make the app deploy-ready. Produces a polyglot GitHub Actions workflow (lint, typecheck, test, build) and multi-stage Dockerfiles. The finish line is CI-green and container-ready, not an actual deploy.
Use when starting a frontend or working on its look and feel, to establish and enforce a DESIGN.md-driven custom design system as the single source of truth for tokens, components, and icons. Make any generated UI (including 21st.dev Magic output) conform to DESIGN.md.
Use when setting up local development services or running the project locally. Establishes the "stateful services in Docker, app runs native" pattern with Postgres, Redis, MinIO, and Mailpit.
Use after the plan is signed off, to drive the autonomous, plan-gated build to completion. Orchestrates per-task implementation, review, and verification in customer-experience-first order, stopping only on genuine blockers.
Use when building or structuring a React/Next.js + TypeScript + Tailwind frontend, choosing libraries, or wiring design tokens. Provides the opinionated blessed-library stack and the React-vs-Next decision, all on-token to DESIGN.md and accessible to WCAG AA.

Announce at start: "I'm using claude-engineer to drive this project's lifecycle."
Claude-Engineer is a lifecycle orchestrator for building full greenfield web apps end-to-end. It is opinionated: React or Next.js + Tailwind + a DESIGN.md-driven custom design system on the front, FastAPI + SQLAlchemy 2.0 + Alembic + Pydantic v2 on the back, a polyglot monorepo, Docker for stateful services only, and hard quality gates.
It does NOT reimplement general engineering discipline - it calls into superpowers for that and
adds the whole-project glue superpowers lacks (intake → phased plan → autonomous build → finish, plus
durable cross-session memory).
.claude-engineer/progress.md + memory.md + git log over your own recollection (survives compaction).| Stage | claude-engineer skill | calls into superpowers |

Guided path: the /claude-engineer:engineer command walks stages 0→6 in order.
Per-stage path: invoke any skill above directly (e.g. /claude-engineer:plan-project).
references/ docs on demand (read by path) - do not paste them wholesale..claude-engineer/progress.md after each task and .claude-engineer/memory.md on key decisions.
