Read, author, maintain, and validate Open Knowledge Format (OKF v0.2) bundles, knowledge as a directory of markdown files with YAML frontmatter, carrying provenance, trust, lifecycle, and attested computations. Use when a repo holds an OKF bundle (concept docs with a `type` field, an `index.md`/`log.md`), when the user mentions OKF or the Open Knowledge Format, or when asked to author, validate, convert to, or keep an OKF knowledge base current.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Open Knowledge Format (OKF) v0.2 OKF represents knowledge as a plain **directory of markdown files with YAML frontmatter**: no database, SDK, or runtime. If you can `cat` a file, you can read OKF; if you can `git clone` a repo, you can ship it. The one authoritative spec is `SPEC.md` in the Google Cloud knowledge-catalog repository: <https://github.com/GoogleCloudPlatform/knowledge-catalog/blob/main/okf/SPEC.md>. Treat any other site or summary as hearsay. This skill carries the working model inline so it functions offline; read the spec itself for edge cases. The point of v0.2 is that a corpus is now mostly **written and maintained by agents**, so a reader needs frontmatter answers to: what was this made from (provenance), how much should I trust it (trust), is it still true (freshness), and was this number computed the sanctioned way (attestation). ## The model - **Bundle**: a directory tree of markdown; the unit of distribution. There is **no root marker file and no mandated directory name**: a bundle is whatever directory someone declares to be one (`knowledge/`, `okf/`, `.okf/` are conventions, not spec). Never guess, take the location from the user or from …

How to install
mdr add everruns/yolop/okf@sha256:c9ee4ccff7a65e7bThe line at the top of this page pins the label git:20260929.212a338, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
