What problem does it solve?
It removes ambiguity from engineering work by converting a written specification into a concrete, file-by-file implementation plan with effort sizing, dependencies, risks, and a test stub.
Core Features & Use Cases
- Spec-to-Plan Conversion: Reads a spec.md and outputs a ready-to-execute plan.md for the /build phase.
- Implementation Precision: Produces an ordered set of atomic steps that map directly to files and functions to change or add.
- Execution Guardrails: Includes pipeline identifiers, effort sizing, explicit dependency ordering, risk flags, and a structured test plan for unit, integration, manual, and regression coverage.
- Pattern Alignment: Encourages referencing existing repo patterns (FastAPI modules, background tasks, skills injection, claude subprocess behavior, and state persistence conventions).
Quick Start
Use the technical-plan skill with your spec.md so it generates a plan.md that your /build phase can execute without additional clarification.
