Skill Governance

What it does

Treats your local source repo as the single source of truth and makes the Claude Code plugin/skill cache match it.

• Workflow A — Drift check (read-only): compares each source plugin dir against ~/.claude/plugins/cache/<marketplace>/<plugin>/, reporting Stale content, version mismatches, missing cache entries, orphaned cache dirs, and direct-copy drift in ~/.claude/skills/.
• Workflow B — Sync from source: runs claude plugin marketplace update, then uninstall + install at the original scope (user/project) so the cache re-fetches. No hand-copying files.
• Workflow C — Clean old cache versions: keeps only the latest semver dir, but verifies the latest matches source before deleting anything.
• Workflow D — Point a marketplace at local source: remove/add with --scope user, then verify.
• Workflow E — Audit loose userSettings skills: classifies skills in ~/.claude/skills, ~/.codex/skills, ~/.agents/skills as lock-managed, source-backed copy, thin template, loose-but-valuable, or obsolete backup — and moves retirees into retired-skills/<reason>-<date>/ instead of rm -rf.

It also ships an ignore list (.git, node_modules, __pycache__, *-workspace, dist, …), suite-plugin rules, a standard markdown report template, and a troubleshooting section.

Who it's for

• Authors who publish their own Claude Code skills/plugins via a marketplace
• Users whose caches have gone stale or accumulated duplicate versions
• Anyone whose ~/.claude/skills/ is full of untracked, mystery-origin skills
• Maintainers enforcing policy: official commands only, preserve install scope

Examples

1. "Check skill drift" → a per-marketplace table report: 3 stale plugins, 1 version mismatch, 2 orphans. Nothing is modified.
2. "Sync skills from source" → confirms the marketplace points at the local path, reinstalls only the drifted plugins at their original scope, then prunes old cache versions.
3. "Clean up my thin user skills" → counts lines and checks for scripts/references, retires replaceable templates into a dated backup folder, and keeps the ones with real methodology.

Install the skill I found on Claude Skill Mart.
Copy the daymade-skill/skill-governance folder from the GitHub repo daymade/claude-code-skills into my ~/.claude/skills/skill-governance/.
When it's done, tell me in one line what this skill can do.
