What's Wrong?

When running /plugin update, the marketplace git repository is updated correctly, but the plugin cache in ~/.claude/plugins/cache/ is not cleared or updated. The installed_plugins.json file also retains the old gitCommitSha.

This means updated plugin files are not reflected until the cache is manually deleted.

What Should Happen?

Plugin cache should be invalidated or updated when /plugin update is run, so that changes in the marketplace are reflected immediately.

Error Messages/Logs

No error messages - the command reports success but cache remains stale.

Evidence:
- ~/.claude/plugins/marketplaces/ - Updated (git pull works) ✓
- ~/.claude/plugins/cache/ - Not updated (old files remain) ✗
- ~/.claude/plugins/installed_plugins.json - gitCommitSha not updated ✗

Steps to Reproduce

1. Add a private marketplace hosted on GitLab:
   /plugin marketplace add git@gitlab.com:your-org/your-marketplace.git

2. Install a plugin from the marketplace:
   /plugin install your-plugin@your-marketplace

3. Make changes to the plugin in the marketplace repository (e.g., update commands or agents)

4. Run /plugin update

5. Check cache directory - files remain outdated:

   ls -la ~/.claude/plugins/cache/
   

6. Compare with marketplace directory - this is updated:
   cd ~/.claude/plugins/marketplaces/your-marketplace && git log -1

Workaround: Manually delete cache directory:
rm -rf ~/.claude/plugins/cache/
