Unclear The finding does not confirm what the extra value on the success line is, only that it is probably a version.
What
The detail menu for a single plugin, opened through /plugin, changed in several ways:
- "Update now" is shown in the suggestion colour and "Uninstall" in the error colour.
- The success line after an action can add an extra value at the end.
- After an uninstall, "· data preserved" is shown based on whether the plugin's data folder was actually kept.
- The menu is guarded so that one action cannot run twice at once.
Why
The risky action stands out, and after uninstalling you can see whether the plugin's saved data is still on your machine.
Names in the bundle/plugin
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.

A small documentation edit on Explore the .claude directory touched a line naming /plugin after this was published.
