Unclear Whether plugins were already uninstalled this way before, with only the report being new, is not settled.
What
A plugin marketplace is a catalogue of plugins you have added to Claude Code. When you run claude plugin marketplace remove, the output used to say only that the marketplace was removed. It now also:
- lists the plugins from that marketplace that were uninstalled with it
- says their saved options, secrets and data are deleted where possible
- explains that to use one again you add the marketplace back and reinstall the plugin
Why
Removing a marketplace also removes its installed plugins and their data, and you can now see exactly which ones went.

Error reference modified, high confidence
known_marketplaces.json has an entry named "claude.code.plugins", another spelling of the reserved marketplace name "claude-code-plugins", so it is ignored. Remove it with: claude plugin marketplace remove claude.code.pluginssee the edit
The entry above is what we published on the day. These lines were added later, as Anthropic's own pages caught up, and they sit beside the original rather than replacing it.
Confirmed since
Anthropic's documentation has since written up claude plugin marketplace remove, on Error reference.
* Run `claude plugin marketplace remove <name>`. This also uninstalls the plugins installed from the marketplace and deletes their saved dataerrors see the edit
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
