What problem does it solve? Writing clear, complete, and testable requirements is hard, and gaps or ambiguities in specs often surface only during implementation. This Skill generates domain-focused checklists that act as unit tests for your requirements, validating completeness, clarity, consistency, and coverage before coding begins. ## Core Features & Use Cases - Requirements Quality Validation: Produces checklist items that test whether requirements are complete, unambiguous, consistent, and measurable rather than testing implementation behavior. - Context-Aware Generation: Reads spec.md, plan.md, and tasks.md from the spec-kit feature directory and asks up to three clarifying questions to tailor the checklist to your domain and audience. - Incremental Checklist Files: Creates or appends to domain-named files like ux.md, api.md, or security.md under the feature's checklists folder with sequential CHK identifiers. - Use Case: Before implementing an authentication feature, run the checklist command with a security focus to surface missing requirements such as undefined session timeout behavior or unspecified failure responses. ## Quick Start Ask the assistant to generate a security-focused requirements checklist for the current spec-kit feature.
