SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Turning a feature specification into a concrete technical plan requires resolving unknowns, modeling data, and defining contracts, which is slow and error-prone when done manually. ## Core Features & Use Cases - Plan Workflow Execution: Runs the setup script, loads the feature spec and project constitution, and fills the implementation plan template with technical context. - Research & Design Artifacts: Generates research.md, data-model.md, contracts/, and quickstart.md through structured Phase 0 and Phase 1 workflows. - Extension Hooks: Executes optional and mandatory pre/post hooks defined in .specify/extensions.yml before and after planning. - Use Case: After writing a spec for a new feature, run the plan workflow to produce a constitution-checked implementation plan with resolved clarifications and interface contracts. ## Quick Start Run the speckit plan command in a spec-kit project to generate the implementation plan and design artifacts for the current feature branch.

Frequently Asked Questions about speckit-plan

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I generate an implementation plan from a feature spec?▼

Run the plan workflow in a spec-kit project. It executes setup-plan.ps1 to resolve paths, loads the feature spec and constitution, then fills the plan template and produces research.md, data-model.md, contracts, and quickstart.md.

What artifacts does the spec-kit planning workflow produce?▼

The workflow produces research.md in Phase 0 to resolve all NEEDS CLARIFICATION items, then data-model.md, interface contracts under contracts/, and quickstart.md in Phase 1, plus the filled implementation plan.

Does speckit-plan require a specific project structure?▼

Yes, it requires a spec-kit project with a .specify directory containing scripts, memory/constitution.md, and templates. The setup script returns FEATURE_SPEC, IMPL_PLAN, FEATURE_DIR, and BRANCH paths used by the workflow.

What are extension hooks in the planning workflow?▼

Hooks are commands registered in .specify/extensions.yml under hooks.before_plan or hooks.after_plan. Mandatory hooks are executed automatically before planning continues, while optional hooks are only suggested to the user.

What happens when the constitution check fails during planning?▼

Gate violations cause an ERROR unless they are justified in the plan. The constitution check is evaluated before design and re-evaluated after Phase 1 to confirm the design still complies with project principles.
