About Fission-AI/OpenSpec
Spec-driven development (SDD) for AI coding assistants.
Solo, OpenSpec keeps you and your AI honest on a single repo. On a team, the hard part moves: a feature spans the API server, the web app, and a shared library; requirements are owned by one team and consumed by others; planning starts before any code exists.
Stores are the answer — planning in a repo of its own. The same openspec/ shape you already know (specs and changes), shared by git push like anything else. One source of truth your whole team and every coding agent can read, across every repo.
