What's Wrong?

I have written and maintain a marketplace with plugin-based skills and commands. In order to test this locally, I point my claude code user config to the marketplace directory. After adding a new command to one of the plugins, I could not get new sessions of CC to be aware of the new slash command until I completely removed and re-added the marketplace (updating either the marketplace or the plugin did not help).

What Should Happen?

Updating the marketplace and/or plugin explicitly should see the newly-added components.

Steps to Reproduce

1. Install a marketplace plugin from a local directory that has skills but no commands
2. Add "commands": "./commands/" to the plugin's plugin.json
3. Add a valid command file
4. Use "Update now" on the marketplace/plugin and start a new claude code session
5. Command doesn't appear until marketplace is removed and re-added
