What problem does it solve? Writing feature specifications often leaves gaps, ambiguities, and inconsistencies that only surface during implementation. This Skill generates structured checklists that act as unit tests for requirements, validating completeness, clarity, consistency, and measurability before coding begins. ## Core Features & Use Cases - Requirements Quality Validation: Produces checklist items that test whether requirements are well-written, not whether the implementation works, covering completeness, clarity, consistency, coverage, and edge cases. - Context-Aware Generation: Loads spec.md, plan.md, and tasks.md from the spec-kit feature directory and asks up to three dynamic clarifying questions to calibrate scope, depth, and audience. - Traceable, Appendable Output: Creates or appends to domain-named checklist files (e.g., ux.md, security.md) with CHK-numbered items carrying traceability markers like [Gap], [Ambiguity], and [Spec §X.Y]. - Use Case: Before implementing a new API feature, run the checklist command to generate an api.md checklist verifying that error response formats, rate limits, and authentication requirements are fully specified. ## Quick Start Ask the assistant to generate a security requirements checklist for the current spec-kit feature.
