Overview

Spec Kit is an open-source workflow toolkit that forces AI coding agents to follow a six-step spec process—constitution, specify, clarify, plan, tasks, implement—before generating code. It targets Python 3.11+ and integrates with popular agents like Claude Code, Cursor, Copilot, Codex, and Gemini CLI. Developers should care because it makes AI-assisted coding auditable, repeatable, and more reliable for complex features.
