OKF Pro is a profile of OKF (Open Knowledge Format) — "pro" as in profile, the term of art for a constrained application of a general format, not as in a paid tier; this is Apache 2.0 like the rest of the ecosystem. It turns a bundle into a working memory an agent is held to. `okf pro setup` writes the bundle and the governance around it — the Claude Code hooks, the pre-commit hook, the CI workflow, the skill — and `okf pro hook` runs one gate against one hook event: reconcile before you add, keep the board and the work in step, attest what you did not verify, close the day with a counted snapshot. The same invariants run again as `okf pro audit`, the CI door. Every conformance and curation question is the okf gem's to answer; what this gem owns is the policy on top and the contract underneath it — blocking checks fail closed, feedback checks fail loud, and no check ever fails silent.
