validate SKILL.md skillA
validate from scaccogatto/okf-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add scaccogatto/okf-skills/validate@git:20260901.0ace7f7Pins git:20260901.0ace7f7 in mdr.lock. Pin the fingerprint instead.

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`.
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
# 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.
```bash
uv run "${CLAUDE_SKILL_DIR}/scripts/okf_validate.py" $ARGUMENTS
```
If `uv` is unavailable, fall back to:
```bash
python3 -m pip install --quiet pyyaml && \
python3 "${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
…Read the whole file at its exact version.
How to install
mdr add scaccogatto/okf-skills/validate@sha256:6544ba26a5fe504dThe line at the top of this page pins the label git:20260901.0ace7f7, 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.
