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. ## Core Features & Use Cases - Planning Workflow Execution: Runs the spec-kit plan workflow via setup-plan.ps1, loading the feature spec and constitution to fill the implementation plan template. - Research and Design Artifacts: Generates research.md, data-model.md, contracts/, and quickstart.md through structured Phase 0 and Phase 1 steps. - Extension Hooks: Executes optional and mandatory before/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 plan with resolved clarifications, entity models, and validation guides. ## Quick Start Ask the agent to run the speckit plan workflow for the current feature branch to generate the implementation plan and design artifacts.
