Skill Governance (source-of-truth cache sync)

A maintenance skill that detects, syncs, and cleans up drift between your local skill source repos and Claude Code's plugin cache.

UtilitiesAdvanced★ 1,323⑂ 212AI score 8/10Last updated: Aug 8, 2026

What it does

Read-only drift check: compares the source dirs declared in .claude-plugin/marketplace.json against ~/.claude/plugins/cache/, reporting stale, version mismatch, missing from cache, orphaned, and direct-copy drift.
Official-command sync: rebuilds the cache via claude plugin marketplace update, uninstall, and install instead of hand-copying files, preserving the original install scope (user or project).
Old version cleanup: sorts semver subdirectories, keeps only the newest, and refuses to delete if the newest still doesn't match source.
Marketplace repointing: swaps a marketplace over to a local source path and verifies the result.
Loose user-skill audit: classifies skills under ~/.claude/skills, ~/.codex/skills, ~/.agents/skills as lock-managed, source-backed copy, thin template, loose-but-valuable, or obsolete backup — and retires them with mv into dated retired-skills/ folders instead of rm -rf.
Includes ignore lists (.git, node_modules, *-workspace, dist…), suite-plugin rules, a Markdown report template, and troubleshooting notes.

Who it's for

Skill/plugin authors who must keep a local source repo and marketplace cache in sync
Heavy Claude Code users whose skill list has grown messy and untraceable
Maintainers distributing several skill repos to a team who need version consistency

Example uses

"Check skill drift" → get a per-marketplace Markdown report with tables for stale, version mismatch, and orphaned plugins.
"Sync skills from source" → repoint the marketplace to local source, reinstall affected plugins at their original scope, then prune old version dirs.
"Clean up thin user skills" → only script-free, reference-free template skills get moved to retired-skills/thin-2025-06-01/, while valuable ones stay.

Try it now, no install

Paste this into Claude to use the skill without installing anything.

Read the instructions in this file and follow them to help me:
https://raw.githubusercontent.com/daymade/claude-code-skills/HEAD/daymade-skill/skill-governance/SKILL.md

What I want: (describe your task here)

If Claude can't open the link, open it yourself and paste the contents instead.

↓ If it works for you, download the ZIP below and install it. Then it runs on its own — no pasting each time.

Install in the Claude app (no terminal)

Download the ZIP with the button below.
In Claude, open Settings → Capabilities and turn on 'Code execution and file creation'. (one time)
Go to Customize → Skills → + → 'Upload a skill' and upload the ZIP.

↓ Download ZIP

Install in Claude Code

Let Claude do it — paste this into Claude Code

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.

Install with a command instead

git clone https://github.com/daymade/claude-code-skills.git && mkdir -p ~/.claude/skills && cp -r claude-code-skills/daymade-skill/skill-governance ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

Open a terminal and cd into any working directory.
Clone the repo: git clone https://github.com/daymade/claude-code-skills.git
Create the skills folder if needed: mkdir -p ~/.claude/skills
Copy just this skill: cp -r claude-code-skills/daymade-skill/skill-governance ~/.claude/skills/
Restart Claude Code and confirm skill-governance shows up in your skill list.
Before using it, run claude plugin marketplace list to learn your own marketplace names, and name them explicitly instead of relying on the daymade-skills defaults.
Start with the read-only request ("check skill drift"), and only approve the sync/cleanup workflows after reviewing the report.
