# Blueprint — Construction Plan Generator Turn a one-line objective into a step-by-step construction plan that any coding agent can execute cold. ## When to Use - Breaking a large feature into multiple PRs with clear dependency order - Planning a refactor or migration that spans multiple sessions - Coordinating parallel workstreams across sub-agents - Any task where context loss between sessions would cause rework **Do not use** for tasks completable in a single PR, fewer than 3 tool calls, or when the user says "just do it." ## How It Works Blueprint runs a 5-phase pipeline: 1. **Research** — Pre-flight checks (git, gh auth, remote, default branch), then reads project structure, existing plans, and memory files to gather context. 2. **Design** — Breaks the objective into one-PR-sized steps (3–12 typical). Assigns dependency edges, parallel/serial ordering, model tier (strongest vs default), and rollback strategy per step. 3. **Draft** — Writes a self-contained Markdown plan file to `plans/`. Every step includes a context brief, task list, verification commands, and exit criteria — so a fresh agent can execute any step without reading prior steps. 4. **Review** — Delegates adversarial review to a strongest-model sub-agent (e.g., Opus) against a checklist and anti-pattern catalog. Fixes all critical findings before finalizing. 5. **Register** — Saves the plan, updates memory index, and presents the step count and parallelism summary to the user. Blueprint detects git/g...
