What problem does it solve? Turning a feature specification into a concrete implementation plan requires resolving technical unknowns, designing data models, and defining contracts, which is time-consuming and error-prone when done manually. ## Core Features & Use Cases - Plan Workflow Execution: Runs the spec-kit planning workflow via setup-plan.sh, filling the Technical Context and Constitution Check sections of the plan template. - Research & Design Artifacts: Generates research.md, data-model.md, contracts/, and quickstart.md by resolving NEEDS CLARIFICATION items and extracting entities from the feature spec. - Extension Hooks: Dispatches optional and mandatory before_plan and after_plan hooks defined in .specify/extensions.yml. - Use Case: After writing a feature spec in a spec-kit project, invoke this Skill to produce a complete implementation plan with resolved research questions, a data model, API contracts, and a validation quickstart guide. ## Quick Start Run the speckit-plan skill to generate an implementation plan and design artifacts for the current feature branch.
