SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Speckit-plan executes the implementation planning workflow using the plan template to generate design artifacts.

Core Features & Use Cases

  • Orchestrates a multi-phase planning flow (outline, research, data-model, contracts) from a plan template.
  • Integrates with spec-kit projects (requires .specify/) to produce artifacts like research.md, data-model.md, and contracts docs.
  • Supports pre/post hook extension checks and automatic context updates during planning.

Quick Start

Run the speckit-plan skill on a spec-kit project to generate a complete design-artifact plan from your repository structure.

FAQPage Schema
How do I generate design artifacts for a spec-kit project?

To generate design artifacts for a spec-kit project, run the speckit-plan workflow on a repository containing the .specify directory. It executes a multi-phase plan to produce artifacts like research.md, data-model.md, and contracts docs.

What is implementation planning workflow orchestration?

Implementation planning workflow orchestration automates multi-phase project design by executing a plan template across research, data modeling, and contract phases. It validates inputs, updates agent context, and enforces constitution checks to output structured design artifacts.

Do I need a .specify directory to use implementation planning workflows?

Yes, you need a .specify directory. The planning workflow specifically targets spec-kit projects and requires this directory structure to load the IMPL_PLAN template and correctly generate the associated design artifacts.

How do I orchestrate a multi-phase plan including research and data modeling?

You orchestrate a multi-phase plan by loading the IMPL_PLAN template, which automatically sequences through outline, research, data-model, and contract phases. The workflow enforces error gating and updates context during the planning process.

Does implementation planning support pre and post hook extension checks?

Yes, implementation planning supports pre and post hook extension checks. These hooks integrate with the planning flow to enforce constitution checks and error gating, ensuring valid context updates before generating design artifacts.
