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 feature directory under specs/ with a spec.md 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. - Extension Hooks: Runs optional or mandatory before_specify and after_specify hooks defined in .specify/extensions.yml, such as automatic git branch creation. - Use Case: Type a feature idea like "add OAuth2 login for the mobile app" and receive a numbered spec directory with a validated specification ready for /speckit-plan. ## Quick Start Ask the agent to create a feature specification by describing the feature you want, for example: specify a user notification system with email and in-app alerts.
