What problem does it solve? Turning a rough feature idea into a complete, testable specification is slow and inconsistent. This Skill converts a natural language feature description into a structured spec.md file inside a spec-kit project, complete with user scenarios, functional requirements, success criteria, and a quality checklist. ## Core Features & Use Cases - Specification Generation: Parses a feature description and writes a structured spec.md using the project's resolved spec-template, with numbered feature directories under specs/. - Quality Validation: Creates a requirements checklist and iteratively validates the spec against content quality, requirement completeness, and readiness criteria, with up to 3 clarification questions for ambiguous points. - Extension Hooks: Executes before_specify and after_specify hooks defined in .specify/extensions.yml, including mandatory git branch creation hooks. - Use Case: A product manager types a feature idea like "add OAuth2 login for the mobile app" and receives a ready-to-plan specification at specs/003-oauth2-login/spec.md with measurable success criteria. ## Quick Start Ask the agent to create a feature specification by describing your feature, for example: create a spec for adding user authentication with OAuth2 to the API.
