What problem does it solve? Turning a feature specification into a concrete implementation plan requires structured research, data modeling, and contract design, which is time-consuming and inconsistent when done manually. This Skill automates the planning workflow so design artifacts are generated consistently from your spec. ## Core Features & Use Cases - Automated Plan Setup: Runs the spec-kit setup script to locate the feature spec, plan file, and branch context automatically. - Phased Design Generation: Produces research.md, data-model.md, API contracts, and quickstart.md following the plan template phases. - Constitution Gate Checks: Evaluates the project constitution before and after design, raising errors on unjustified violations or unresolved clarifications. - Use Case: After writing a feature spec with spec-kit, invoke this Skill to resolve technical unknowns, define the data model, and generate interface contracts before any code is written. ## Quick Start Run the speckit-plan workflow on my current feature branch to generate the implementation plan and design artifacts from the feature spec.
