What problem does it solve? Turning a feature specification into a concrete technical design requires choosing frameworks, defining data models, and writing API contracts, which is time-consuming and error-prone when done manually. This Skill automates that planning phase by generating a structured implementation plan from an existing spec.md file. ## Core Features & Use Cases - Spec Quality Gate: Scores the feature specification out of 10 by checking requirement counts, measurable success criteria, unresolved clarifications, and story coverage before planning begins. - Design Artifact Generation: Produces research.md, data-model.md, API contracts, and quickstart.md from the spec, with dependency-ordered implementation strategy. - Constitution Enforcement: Validates every technical decision against project governance principles and halts on violations with compliant alternatives. - Use Case: After writing a feature spec for a new checkout flow, run this Skill to select the tech stack, define the PostgreSQL schema, generate REST API contracts, and produce a semantic diff when re-planning. ## Quick Start Run the plan skill to generate a technical design document from my current feature specification.
