## Intro

Spec Kit is GitHub's open-source toolkit for spec-driven development with 85,500+ stars. Instead of vibe coding, you write product specifications that become executable artifacts for AI agents. It supports Claude, GitHub Copilot, Gemini, and other AI coding tools, with 40+ community extensions for code review, integration, and workflow orchestration.

Best for: engineering teams who want predictable AI-assisted development outcomes. Works with: Claude Code, GitHub Copilot, Gemini, Cursor. Setup time: under 3 minutes.

## Spec Kit — From Specifications to Working Code

### How It Works

Spec Kit follows a structured workflow:

1. **Constitution** — Define project principles in `/speckit.constitution`
2. **Specification** — Write detailed product specs
3. **Planning** — AI generates implementation plans from specs
4. **Tasks** — Plans break into executable tasks
5. **Implementation** — AI agents execute tasks following the spec

### Key Features

- **Spec-Driven Methodology**: Specs become the single source of truth for AI agents
- **Multi-Agent Support**: Works with Claude, Copilot, Gemini, and more
- **40+ Extensions**: Community-built extensions for code review, CI/CD, and orchestration
- **Customizable Presets**: Reshape terminology and workflows for your team
- **Full Lifecycle**: From constitution to implementation with traceability

### Installation Options

```bash
# Persistent install (recommended)
uv tool install specify-cli --from git+https://github.com/github/spec-kit.git

# One-time execution
uvx --from git+https://github.com/github/spec-kit.git specify init my-project
```

### Community Walkthroughs

Full lifecycle demos are available for .NET, Java, Go, Spring Boot, and React projects — showing the complete spec → plan → task → implement flow.

## Spec Kit — From Specs to Runnable Code

### Workflow

1. **Constitution** — define project principles in `/speckit.constitution`
2. **Specification** — write detailed product specs
3. **Planning** — AI generates an implementation plan from the spec
4. **Tasks** — the plan is broken into executable tasks
5. **Implementation** — AI agents execute tasks per the spec
