Okforge Maintain

Open Knowledge Format (OKF) maintenance

OKF is an open, human- and agent-friendly format for knowledge — the metadata and curated insight that surrounds a system. This repo's bundle lives at .okf/. Spec: https://github.com/GoogleCloudPlatform/knowledge-catalog/blob/main/okf/SPEC.md

The bundle is derived from source. Each folder is generated from specific files; when those files change, the folder's docs drift. This skill keeps three things consistent so you can focus on accurate prose: the OKF format, the folder<->source mapping, and link integrity.

A bundled CLI owns the mechanics; you own the prose. Run it with npx from the project root (Node >= 20.12):

npx okforge <command>          # map | folders | sources <folder> | stale | check | nudge

Pick the mode from what the user asked

• "refresh okf", "update the OKF docs for X", "the API changed, update okf" → Refresh mode (the common case).
• "set up okf", "create an OKF bundle", bundle missing → Scaffold mode.
• "check okf", "is the bundle conformant", "any dead links" → Check mode.

The folder <-> source mapping

The mapping is per-repository data, declared in .okforge.config.json at the project root. okforge ships with none of it. The file shape is:

{
  "folders": {
    "runtime_concepts": ["packages/foo/src/model/", "packages/foo/src/event/"],
    "config_formats": ["packages/foo/data/schemas/thing.schema.json"]
  }
}

Each key is an OKF concept folder; each value is the list of source path prefixes that folder is derived from. npx okforge map prints the resolved mapping; npx okforge sources <folder> prints one folder's source paths; npx okforge folders lists the declared folders. Never hardcode the mapping in docs — read it from the config so there is one source of truth (the hook reads it too). When the codebase moves, edit .okforge.config.json.

Refresh mode

1. Determine which folder(s) to refresh. If the user named one, use it. If they said "whatever changed", run npx okforge stale — it lists folders whose source changed since HEAD without the folder being edited.
2. For each folder, run npx okforge sources <folder> and READ those real files.
3. Regenerate the affected concept docs from what you read, following the OKF authoring rules below. Only rewrite docs whose underlying source actually changed; leave correct docs untouched. Preserve existing filenames unless the source they document was renamed or removed.
4. If a concept's source was deleted, delete its doc and remove it from the folder index.md. If a new source appeared, add a new concept doc and link it from index.md.
5. Update the folder index.md, and if folders were added/removed update the root .okf/index.md, the .okforge.config.json mapping, and prepend a dated entry to .okf/log.md.
6. Run npx okforge check and resolve every problem it reports before finishing.

Scaffold mode

Create .okforge.config.json at the project root with the folder<->source mapping for this repository (ask the user or infer it from the layout). Then create .okf/index.md (the only file with frontmatter: okf_version: "0.1" and type: Bundle Index) and .okf/log.md. Create the folders from the mapping and refresh each. Finish with npx okforge check.

Check mode

Run npx okforge check. It verifies snake_case names, that every non-index .md has a non-empty frontmatter type, that sub-folder index.md files carry no frontmatter, and that bundle-relative .md links resolve. Report results; fix problems if the user asked you to.

OKF authoring rules (follow exactly when writing docs)

• File names: snake_case only. No kebab-case, no spaces.
• Concept docs: every non-index .md starts with a YAML frontmatter block delimited by --- lines. Required: type (non-empty, e.g. Config Format, Concept, Data Model, API Endpoint, CLI Command, Crew, Package). Recommended: title, description (one sentence), resource (path/URI of the real underlying asset), tags, timestamp (ISO 8601 — set to today's date on refresh).
• Body: favor structural markdown — headings, lists, tables, fenced code — over prose. Use conventional sections where they apply: # Schema (field/ shape), # Examples (code), # Citations (sources).
• Index files (reserved): index.md has NO frontmatter (except the root bundle index). It lists the folder's concepts as bulleted markdown links with one-line descriptions, optionally grouped under # headings.
• Links: cross-link concepts with relative markdown paths from the doc, e.g. [job store](../runtime_concepts/job_store.md) or [sibling](./sibling.md). Never use bundle-root absolute paths (those beginning with /, e.g. /runtime_concepts/job_store.md). Link to real repo source files (in # Citations) with repo-relative paths from the doc, e.g. ../../packages/foo/src/model/job_store.ts.
• Grounding (critical): every claim must come from the real source you read. Do not invent field names, routes, flags, states, or behavior. If uncertain, omit. Quote real schema fields and real route paths.
• Style: plain English, no slang, no abbreviations.

Companion hook

A Stop hook (npx okforge nudge, registered in .claude/settings.json) nudges at session end when mapped source changed but .okf/ was not updated. It reads the same .okforge.config.json mapping via npx okforge stale, so editing the mapping updates both the skill and the nudge.
