What problem does it solve? Turning a rough feature idea into a complete, testable specification is slow and error-prone. This Skill converts a plain-language feature description into a structured spec.md file with user scenarios, functional requirements, success criteria, and a quality checklist, ready for planning. ## Core Features & Use Cases - Spec Generation: Creates a feature directory under specs/ with a spec.md based on the spec-kit template, including user scenarios, functional requirements, and measurable success criteria. - Quality Validation: Generates a requirements checklist and iteratively validates the spec against completeness and testability criteria, with up to 3 clarification questions presented as option tables. - Extension Hooks: Supports before_specify and after_specify hooks via .specify/extensions.yml for optional git branch creation and post-processing. - Use Case: A product manager types a feature idea like "add OAuth2 login" and receives a numbered spec directory (e.g., specs/003-oauth2-login/spec.md) with validated requirements 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".
