speckit-plan

To generate an implementation plan, this Skill transforms a feature specification into design artifacts and resolved research decisions. It produces research.md, data-model.md, contracts, and quickstart.md by executing Phase 0 research and Phase 1 generation workflows.

A constitution check validates your implementation plan against predefined guardrails, halting the workflow on gate failures or unresolved clarifications. It ensures your design artifacts comply with project rules before you proceed to development.

To resolve NEEDS CLARIFICATION items, the workflow captures these open questions and resolves them into a research.md file. This ensures all research decisions are documented and clarified before data-model and contract generation begins.

No, you must run the setup-plan PowerShell step before using this workflow. It prepares the required .specify/ directory structure, loads constitution context, and updates agent context to ensure the planning workflow executes correctly.

An artifact-driven planning workflow produces research.md, data-model.md, contracts/, and quickstart.md. These artifacts provide the structured design documents and resolved decisions needed to achieve full implementation readiness.

Your implementation plan halts because the workflow enforces constitution gate checks and stops if it encounters unresolved clarifications. You must resolve all open research questions to pass the validation and continue generating contracts.
