SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Turning a feature specification into a concrete implementation plan requires resolving technical unknowns, modeling data, and defining contracts, which is slow and inconsistent when done manually. ## Core Features & Use Cases - Plan Workflow Execution: Runs the spec-kit planning workflow via setup-plan.ps1, filling Technical Context and Constitution Check sections in the plan template. - Research & Design Artifacts: Generates research.md, data-model.md, contracts/, and quickstart.md, resolving all NEEDS CLARIFICATION items. - 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, run this Skill to produce a complete Phase 0-1 design package with data models, API contracts, and a validation quickstart guide. ## Quick Start Ask the agent to run the speckit plan workflow for the current feature branch to generate the implementation plan and design artifacts.

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 speckit plan workflow in a spec-kit project. It executes setup-plan.ps1 to locate the feature spec and plan template, then fills Technical Context, resolves unknowns in research.md, and produces data-model.md, contracts, and quickstart.md.

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

The workflow produces research.md with resolved clarifications, data-model.md with entities and validation rules, a contracts directory for external interfaces, and quickstart.md with runnable validation scenarios.

Does speckit-plan require a specific project structure?▼

Yes, it requires a spec-kit project with a .specify directory containing scripts/powershell/setup-plan.ps1 and memory/constitution.md. Without this structure the setup step cannot locate the feature spec and plan template.

What are extension hooks in the plan workflow?▼

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

Why does the plan workflow fail with gate errors?▼

The workflow errors when Constitution Check gates fail without justification or when NEEDS CLARIFICATION items remain unresolved after Phase 0 research. Resolve the unknowns or justify violations in the plan to proceed.
