What problem does it solve? Turning a feature specification into a concrete implementation plan requires resolving technical unknowns, designing data models, and defining contracts — a process that is often ad hoc and inconsistent. This Skill automates that planning workflow, producing structured design artifacts from a spec. ## Core Features & Use Cases - Automated Plan Setup: Runs the spec-kit setup script to locate the feature spec, plan file, and branch context. - Two-Phase Design Workflow: Phase 0 resolves all NEEDS CLARIFICATION items into research.md; Phase 1 generates data-model.md, API/interface contracts, and quickstart.md. - Constitution & Gate Checks: Evaluates project constitution rules before and after design, erroring on unjustified violations. - Extension Hooks: Supports optional and mandatory pre/post hooks declared in .specify/extensions.yml. - Use Case: After writing a feature spec with spec-kit, invoke this Skill to produce research findings, a data model, endpoint contracts, and a validation quickstart — ready for task breakdown and implementation. ## Quick Start Ask the agent to run the implementation planning workflow for the current feature branch so it generates research.md, data-model.md, contracts, and quickstart.md from the feature spec.
