Brain Lint
Use this skill as the gate for every ontology-brain/ change.
Mechanical Gate
Run from anywhere inside ontology-brain/:
python3 .claude/skills/brain-lint/scripts/wiki_link_check.py
The script locates the brain root by walking upward to ontology.md plus objects/. It accepts an explicit root path when needed.
It checks:
- relative links resolve and stay inside the brain;
- no absolute local links or
file: URIs;
- no Obsidian wikilinks inside the brain;
- heading anchors exist;
- non-meta pages have inbound links;
- frontmatter keys are known shared properties or typed link properties;
supersedes and superseded_by are mirrored;index.md matches regeneration from build_index.py.
Fix the brain first. Change the checker only when the checker is demonstrably wrong, and keep schema documentation aligned.
Generated Index
index.md is derived. Do not hand-edit it. Regenerate with:
python3 .claude/skills/brain-lint/scripts/build_index.py
Use summary: in page frontmatter for the optional one-line hook on index rows.
Semantic Audit
When asked for a full health check, also inspect:
- duplicated facts that should have one canonical home;
- stale copied values;
- vague object types or premature folders;
- links that answer no domain question;
- missing source provenance;
[UNVERIFIED] claims that can now be verified;- relationships with their own dates, status, or evidence that should be promoted to pages.
Record meaningful audit work in log.md with a lint entry.
