The spec framework for building the right thing and building it right
Synopsis
OpenSpec is a lightweight and configurable framework for creating and managing software specifications.
With OpenSpec, you capture what you want to build in a spec and keep your team and coding agents aligned as the work evolves. We help you refine the requirements, validate that they describe the right thing, and verify that the implementation matches.
In essence, OpenSpec helps you build the right thing and build it right.
