What problem does it solve? Large engineering tasks like migrations and refactors lose context between sessions and agents, causing rework and broken dependencies. Blueprint turns a one-line objective into a structured, multi-step plan where every step carries a self-contained context brief that a fresh agent can execute cold. ## Core Features & Use Cases - Five-phase pipeline: Research, Design, Draft, Review, and Register phases produce a Markdown plan in plans/ with dependency edges, parallel step detection, model tier assignments, and rollback strategies per step. - Adversarial review gate: A strongest-model sub-agent reviews every plan against a checklist and anti-pattern catalog before finalization. - Plan mutation protocol: Steps can be split, inserted, skipped, reordered, or abandoned with a formal audit trail. - Use Case: Run /blueprint myapp "migrate database to PostgreSQL" to produce a plan with ordered steps covering driver setup, migration scripts, repository layer updates, integration tests, and cleanup, each with verification commands and exit criteria. ## Quick Start Ask the agent to create a blueprint plan for migrating your project database to PostgreSQL across multiple PRs.
