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: Parses a feature description, extracts actors, actions, data, and constraints, and writes a structured specification using the project's spec-template. - Quality Validation: Creates a requirements checklist and iteratively validates the spec against completeness, testability, and technology-agnostic criteria, with up to 3 clarification questions for ambiguous points. - Extension Hooks: Supports before_specify and after_specify hooks (e.g., automatic git branch creation) configured via .specify/extensions.yml. - Use Case: A product engineer types a feature idea like "add OAuth2 login" and receives a numbered feature directory under specs/ containing a validated spec.md and checklist, ready for /speckit-plan. ## Quick Start Ask the agent to create a feature specification for your idea, for example: run speckit-specify with the description "add user authentication with OAuth2".
