Overview

GitHub Spec-Kit is an open-source toolkit that enables spec-driven development workflows, allowing teams to focus on product scenarios and predictable outcomes rather than improvising code piece by piece. Officially maintained by GitHub, it provides templates, conventions, and tooling to write specifications before implementation, ensuring alignment between product requirements and technical execution. Spec-Kit integrates naturally with GitHub Issues, Pull Requests, and Projects for seamless workflow integration.
