What problem does it solve? Turning a feature specification into a concrete implementation plan requires structured research, data modeling, and contract definition, which is slow and inconsistent when done ad hoc. This Skill automates the spec-kit planning workflow so design artifacts are produced consistently from a feature spec. ## Core Features & Use Cases - Plan Setup and Context Loading: Runs the setup-plan script, parses feature spec paths, and loads the project constitution for gate evaluation. - Phase 0 Research: Resolves all NEEDS CLARIFICATION items and consolidates decisions, rationale, and alternatives into research.md. - Phase 1 Design Artifacts: Generates data-model.md, interface contracts, and quickstart.md validation guides from the feature spec. - Extension Hooks: Executes optional and mandatory before/after plan hooks defined in .specify/extensions.yml. - Use Case: After writing a feature specification with spec-kit, invoke this Skill to produce a complete implementation plan with research findings, entity models, API contracts, and a quickstart validation guide. ## Quick Start Ask the assistant to run the speckit plan workflow for the current feature branch to generate the implementation plan and design artifacts.
