What problem does it solve? Turning a rough feature idea into a complete, testable specification is slow and error-prone. 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 feature directory under specs/ with a spec.md built from the resolved spec-template, using sequential or timestamp-based numbering. - 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 optional and mandatory before_specify and after_specify hooks defined in .specify/extensions.yml, such as automatic git branch creation. - Use Case: Describe a feature like "add OAuth2 login for the mobile app" and receive a numbered spec directory containing a stakeholder-ready specification and a quality checklist, prepared for the clarify or plan phase. ## Quick Start Run the speckit-specify skill with a feature description such as "add user authentication with OAuth2" to create the feature specification.
