What problem does it solve? Turning a feature specification into a concrete implementation plan requires resolving technical unknowns, defining data models, and drafting interface contracts, which is slow and inconsistent when done manually. ## Core Features & Use Cases - Plan Workflow Execution: Runs the spec-kit planning workflow via setup-plan.ps1, filling Technical Context and Constitution Check sections in the implementation plan. - 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: Executes optional and mandatory pre/post hooks defined in .specify/extensions.yml before and after planning. - Use Case: After writing a feature spec for a new CLI command, run this Skill to produce a complete plan with resolved technical decisions, a data model, API contracts, and a quickstart validation guide. ## Quick Start Ask the agent to run the speckit plan workflow for the current feature branch to generate the implementation plan and design artifacts.
