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, then validates it against a quality checklist. ## Core Features & Use Cases - Spec Generation: Creates a feature directory under specs/ with a spec.md file built from the resolved spec-template, using sequential or timestamp-based numbering. - Quality Validation: Generates a requirements checklist and iterates on the spec until it passes content, completeness, and readiness checks. - Clarification Handling: Flags up to 3 critical [NEEDS CLARIFICATION] markers and presents structured multiple-choice questions to resolve them. - Use Case: A product manager types a feature idea like "add OAuth2 login for the mobile app" and receives a complete, stakeholder-ready specification with acceptance scenarios and success metrics, ready for the planning phase. ## Quick Start Run /speckit-specify followed by a description of the feature you want to specify, such as "add user authentication with OAuth2".
