What problem does it solve? Turning a rough feature idea into a complete, testable specification is slow and inconsistent. This Skill converts a plain-language feature description into a structured spec.md file with user scenarios, functional requirements, and measurable success criteria, then validates it against a quality checklist. ## Core Features & Use Cases - Spec Generation: Creates a numbered feature directory under specs/ with a spec.md built from the resolved spec template, including user scenarios, requirements, success criteria, and assumptions. - Quality Validation: Generates a requirements checklist and iterates on the spec until it passes, resolving up to three [NEEDS CLARIFICATION] markers through structured user questions. - 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: A product manager types a feature idea like "add OAuth2 login for enterprise users" and receives a complete, stakeholder-ready specification at specs/003-oauth2-login/spec.md, ready for planning. ## Quick Start Ask the assistant to run /speckit-specify followed by a description of the feature you want to specify.
