Tool suggestion: open-source health check for large skill lists

Your list leans automation-heavy, where broken tool references hurt most. We maintain an open-source health check for skill/rule libraries: reference graph mapping, orphan and hub detection, conflict and near-duplicate spotting — offline CLI with JSON+HTML reports. Repo: github.com/chenhz01/skill-audit-kit. If useful, happy to run it on this list and share the report here. Not relevant? Feel free to close this issue.
