What problem does it solve? Complex features are hard to break into reviewable, executable chunks. This Skill turns a one-line objective into a structured multi-PR plan where each step is self-contained enough for any agent to execute cold, with review gates to catch planning errors before code is written. ## Core Features & Use Cases - Step Brief Generation: Each step gets a brief with objective, files to create/modify, dependencies, implementation details, verification checklist, and rollback plan. - Adversarial Review: A stronger model reviews the plan against a checklist covering step ordering, dependencies, scope, and hidden complexity, returning a verdict like NEEDS REVISION. - Plan Mutation Protocol: Supports splitting, inserting, skipping, and reordering steps with an audit trail as requirements change. - Use Case: You need to add JWT authentication to a monorepo. The Skill produces Step 1 (user schema), Step 2 (user model), Step 3 (JWT auth), each mapped to its own branch and PR with verification criteria. ## Quick Start Ask the agent to create a blueprint that breaks your feature objective into ordered PR-sized steps with verification and rollback plans.
