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 file with user scenarios, functional requirements, success criteria, and a quality checklist, ready for planning. ## Core Features & Use Cases - Spec Generation: Parses a feature description, extracts actors, actions, data, and constraints, and writes a spec.md file using the project's spec template under a numbered specs/ directory. - Quality Validation: Creates a requirements checklist and iteratively validates the spec against content quality, requirement completeness, and feature readiness criteria, with up to 3 clarification questions for ambiguous points. - Extension Hooks: Supports 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 with measurable success criteria and a validation checklist. ## Quick Start Ask the agent to create a feature specification from your description, for example: run /speckit-specify with the text "add user authentication with OAuth2".
