🌱 Spec Kit

Define what to build before building it — with any AI coding agent.

An open source toolkit for building high-quality software with any AI coding agent — a ready-to-use spec-driven process (or bring your own), endlessly extensible, community-driven, and built for your whole organization.

[!NOTE] **One year of Spec Kit — and 1.0.0**

One year after the first commit, Spec Kit has reached [1.0.0](https://github.com/github/spec-kit/releases/tag/v1.0.0) — not because the work is finished or its shape is frozen, but because the project has grown into something coherent, useful, and shaped by far more people than those who started it.

The lead maintainer's personal anniversary post, [*Spec Kit Turns One — and Ships 1.0.0*](https://www.manorrock.com/blog/2026/08/21/spec_kit_turns_one.html), defines what 1.0.0 actually means for the project: **it is now just a number**. As agents make adapting to change dramatically cheaper, the value moves from stability to adaptability.
