# Spec Kit

Gives coding agents structured processes for spec-driven builds, bug fixes and idea assessment

Category: Devtools. Pricing: Open source. License: MIT.

Platforms: claude-code, cursor, codex, gemini-cli, zed, linux, macos, windows.

## Why you would want it

The specify CLI installs skills or command files for your coding agent, which you then run in chat: constitution once per project, then specify, plan, tasks, implement and converge for each feature. Optional extensions add a bug-fixing flow (assess, fix, test) and an idea assessment flow that ends in a go, clarify or stop decision, with reports saved as Markdown under .specify/. It has integrations for dozens of agents, including GitHub Copilot, Claude Code, Codex CLI, Cursor, Gemini CLI and Zed, and you can customize it with extensions, presets and workflows.

## Best for

- Teams that want a spec before code
- Keeping agent work reviewable step by step
- Using one process across several coding agents

## Use it when

You want a coding agent to work from a written specification, plan and task list rather than one prompt, with artifacts you review at each step.

## Skip it if

Your changes are small enough that a single prompt does the job. The CLI needs Python 3.11+ and uv.

## Install

Install with uv and create a project:

```sh
uv tool install specify-cli
specify init my-project --integration copilot
```
