What problem does it solve? Turning a rough feature idea into a complete, testable specification is slow and inconsistent. This Skill converts a natural language feature description into a structured spec.md file with user scenarios, functional requirements, and measurable success criteria, ready for planning. ## Core Features & Use Cases - Spec Generation: Creates a numbered feature directory under specs/ with a spec.md built from the resolved spec-template, covering user scenarios, requirements, success criteria, and key entities. - Quality Validation: Generates a requirements checklist and iteratively validates the spec against content quality, completeness, and readiness criteria, with up to 3 clarification questions presented as option tables. - Extension Hooks: Runs before_specify and after_specify hooks from .specify/extensions.yml, including git branch creation, and persists the feature directory to .specify/feature.json for downstream commands. - Use Case: Type a feature idea like "add OAuth2 login to the API" and receive a validated, stakeholder-readable specification at specs/003-oauth2-api-integration/spec.md, ready for /speckit-plan. ## Quick Start Run /speckit-specify followed by a description of the feature you want to specify, such as "add user authentication with OAuth2".
