What problem does it solve? Writing clear, complete, and testable requirements is hard, and gaps or ambiguities in specs surface late as costly rework. This Skill generates custom checklists that act as unit tests for requirements, validating the quality of your spec before implementation begins. ## Core Features & Use Cases - Requirements Quality Validation: Generates checklist items that test completeness, clarity, consistency, measurability, and coverage of requirements rather than implementation behavior. - Domain-Focused Checklists: Creates or appends to named checklist files (e.g., ux.md, api.md, security.md) inside the feature's checklists directory with sequential CHK IDs. - Context-Aware Clarification: Derives up to three targeted clarifying questions from your input and the feature's spec, plan, and tasks before generating items. - Use Case: Before implementing a new API feature, run the checklist command with a security focus to produce a reviewer-owned checklist verifying that authentication, error handling, and rate-limiting requirements are fully specified. ## Quick Start Ask the agent to generate a security-focused requirements checklist for the current feature using the speckit-checklist skill.
