See it in action What do the specs actually look like? Plain Markdown — requirements with concrete scenarios, no special syntax to learn. Here's what goes in the specs/ folder created above: Your AI writes these; you review the plan before any code is written. OpenSpec is built with OpenSpec — browse this repo's live specs and in-flight changes for real examples at scale. OpenSpec Dashboard Why teams adopt OpenSpec 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.
