>- 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`.
npx skills add https://github.com/scaccogatto/okf-skills --skill validate
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
${CLAUDE_SKILL_DIR} resolves whether this skill runs as part of the okf
plugin or is installed standalone (e.g. via npx skills add), so the checker is
always found alongside the skill.
Interpret the result:
missing/empty type). The bundle is non-conformant. Fix every one.
cross-link, a malformed v0.2 family, a footnote naming no source, an actor
that misses the §7 shapes, a computation path that resolves nowhere). Never
blocks; broken links in particular are explicitly tolerated by the spec
(§6.1). Fix when cheap.
One warning is worth more than the others: a §7 near-miss such as Human:dana
or human/dana. §5.3 keys trust tiers off the exact lowercase human: prefix,
so the concept silently reads as machine-confirmed when a person did review it.
Fix that one on sight.
v0.1 bundles validate too: a legacy timestamp or # Citations section is
reported as a warning naming its v0.2 replacement (generated.at, sources),
never as an error (§13.1). Under --strict those warnings do fail the run —
that is the migration nudge, and --migrate is the door.
--migrate rewrites the bundle in place before validating — the one mode of
this skill that is not read-only, so say what it will touch before running it on
a bundle the user has not asked to migrate. It is textual (comments, key order
and quoting survive) and idempotent.
uv run "${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.
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).
Take scaccogatto/validate from the repository into ~/.claude/skills for personal
use, or into .claude/skills inside a project.
The agent identifies a skill by the name field in its header. Two skills with the
same name cannot sit side by side — one of them will be ignored.
The instructions reference pip, npx.
Without those the skill loads but fails at the first command.
