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 when done manually. This Skill automates the planning workflow inside a spec-kit project, producing research, data model, contract, and quickstart artifacts. ## Core Features & Use Cases - Automated Plan Setup: Runs the spec-kit setup script to locate the feature spec, plan file, and branch, then loads the project constitution for gate checks. - Phase 0 Research: Resolves every NEEDS CLARIFICATION item in the Technical Context and consolidates decisions, rationales, and alternatives into research.md. - Phase 1 Design Artifacts: Generates data-model.md, interface contracts, and a quickstart validation guide 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 spec with spec-kit, invoke this Skill to produce a complete implementation plan with research findings, entity models, and API contracts ready for task breakdown. ## Quick Start Ask the agent to run the speckit plan workflow for the current feature branch so it generates the implementation plan, research notes, data model, and contracts from the existing feature specification.
