Meet GitHub Spec-Kit: An Open Source Toolkit for Spec-Driven Development with AI Coding Agents

GitHub open sourced Spec-Kit, a toolkit for spec-driven development with AI coding agents.

It adds templates, CLI commands, and workflows for writing specs, planning work, splitting tasks, and validating code.

The goal is to reduce mismatched outputs and make AI-assisted software building more reliable for real projects.

Spec-Kit is designed to work with tools like GitHub Copilot, Claude Code, and Gemini CLI.
