  Check that an Open Knowledge Format (OKF) bundle is conformant with the v0.2
  spec (§11). Use when asked to validate, lint, or check an OKF bundle, or before
  committing changes to one. Runs a deterministic Python checker — not an
  eyeball pass. Also migrates a v0.1 bundle to v0.2 in place with `--migrate`.

Validate an OKF bundle

Run the deterministic conformance checker against the target bundle. Default to the project's `.okf/` directory when no path is given.

uv run "${CLAUDE_SKILL_DIR}/scripts/okf_validate.py" $ARGUMENTS

If `uv` is unavailable, fall back to:

python3 -m pip install --quiet pyyaml && \
python3 "${CLAUDE_SKILL_DIR}/scripts/okf_validate.py" $ARGUMENTS

`${CLAUDE_SKILL_DIR}` resolves whether this skill runs as part of the `okf` plugin or is installed standalone (e.g. via `npx skills add`), so the checker is always found alongside the skill.

Interpret the result:

• **ERROR** → a hard §11 conformance failure (no parseable frontmatter, a

missing/empty `type`, or a file the checker cannot read as UTF-8). The bundle is non-conformant. Fix every one.

Only `index.md` and `log.md` are reserved: §11.1 makes *every* other `.md` in the tree a concept, convention files included. An `AGENTS.md` or `README.md` dropped next to a bundle is therefore an ERROR until it carries frontmatter with a `type` (`Document` reads well), which is the fix; a skip-list would put the checker out of conformance. Move the file above the bundle root if it is not knowledge.

• **warn** → soft guidance (missing recommended field, non-ISO log date, broken

cross-link, a malformed v0.2 family, a footnote naming no source, an actor that misses the §7 shapes, an Attested Computation missing `runtime`, a computation path that resolves nowhere, frontmatter in a reserved file (§8, §9), a root `index.md` carrying extra keys or declaring a different `okf_version` (§12)). Never blocks; broken links in particular are explicitly tolerated by the spec (§6.1). Fix when cheap.

One warning is worth more than the others: a §7 near-miss such as `Human:dana` or `human/dana`. §5.3 keys trust tiers off the exact lowercase `human:` prefix, so the concept silently reads as machine-confirmed when a person did review it. Fix that one on sight.

v0.1 bundles validate too: a legacy `timestamp` or `# Citations` section is reported as a warning naming its v0.2 replacement (`generated.at`, `sources`), never as an error (§13.1). Under `--strict` those warnings do fail the run — that is the migration nudge, and `--migrate` is the door.

Migrating a v0.1 bundle

`--migrate` **rewrites the bundle in place** before validating — the one mode of this skill that is not read-only, so say what it will touch before running it on a bundle the user has not asked to migrate. It is textual (comments, key order and quoting survive) and idempotent.

uv run "${CLAUDE_SKILL_DIR}/scripts/okf_validate.py" .okf --migrate --strict

It hoists `timestamp` to `generated: { by: process:okf-migrate, at }`, lifts a `# Citations` list into `sources`, and bumps `okf_version`. Two limits worth repeating to the user: `generated.by` cannot be recovered for pre-v0.2 content (hence the `process:` actor — the concept stays correctly `unverified` under §5.3), and per-claim `[^id]` attribution was never encoded in v0.1, so only the source list moves up.

Exit codes

Non-zero if any error is present, or if warnings exceed the gate: `--strict` allows none, `--max-warnings N` allows N, the default allows any. Add `--json` for machine-readable output (useful in CI).
