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, 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, including user scenarios, requirements, and success criteria. - Quality Validation: Generates a requirements checklist and iteratively validates the spec against content quality, completeness, and readiness criteria, resolving up to 3 clarification questions with the user. - Extension Hooks: Supports before_specify and after_specify hooks from .specify/extensions.yml for branch creation and post-processing automation. - Use Case: A product owner types a feature idea like "add OAuth2 login" and receives a complete, stakeholder-ready specification at specs/001-oauth2-login/spec.md with a validated quality checklist. ## Quick Start Run /speckit-specify followed by your feature description, for example: create a specification for adding user authentication with OAuth2.
