SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It streamlines the implementation planning workflow for spec‑kit projects, automatically generating design artifacts and ensuring compliance with project specifications.

Core Features & Use Cases

  • Pre‑ and post‑plan hook execution: Detects and runs optional extension hooks defined in .specify/extensions.yml.
  • Research & design phases: Generates research.md, data‑model.md, contract files, and quick‑start guides based on the project spec.
  • Use Case: For a repository that follows the spec‑kit structure, run this skill to produce a complete implementation plan, data model, and related documentation without manual stitching.

Quick Start

Run the speckit-plan skill with optional guidance to start the implementation planning workflow.

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

To generate design artifacts for spec-kit projects, run a planning skill that executes research, data modeling, and contract generation. This produces research.md, data-model.md, and quick-start guides automatically from your project spec.

What is the best way to automate implementation planning for repositories with a .specify structure?

Automating implementation planning for repositories with a .specify structure involves executing pre-plan hooks, conducting research, and generating data models. This workflow ensures compliance with project specifications while producing complete documentation without manual stitching.

Does spec-kit planning support custom extension hooks?

Spec-kit planning supports custom extension hooks defined in .specify/extensions.yml. The workflow detects and executes these optional pre- and post-plan hooks during the implementation planning process.

Do I need PowerShell scripts to run the spec-kit planning workflow?

You need PowerShell scripts and spec-kit templates present in your repository to run the planning workflow. The skill requires this specific environment structure to execute research and generate design artifacts correctly.

What design artifacts are produced when planning implementation for spec-kit projects?

Planning implementation for spec-kit projects produces research.md, data-model.md, contract files, and quick-start guides. These design artifacts are generated based on the project spec during the research and design phases.

Why does my spec-kit planning workflow fail to execute hooks?

Spec-kit planning workflow fails to execute hooks when the .specify/extensions.yml file is missing or incorrectly formatted. The skill requires optional extension hooks to be properly defined in this configuration file to detect and run them successfully.
