What
Claude Code now has a message for refusing a plugin marketplace (a catalog plugins are installed from) whose name looks like one of Anthropic's own. The message says reloading won't help, and then:
- if the marketplace is declared in a settings file, tells you to rename it there to keep it
- otherwise, tells you to remove it with a command or through
/plugin→ Marketplaces, and warns that removing it also uninstalls its plugins and deletes their saved data
Why
This guards against marketplaces pretending to be Anthropic's, and tells you what to do if one of yours is caught by it.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
The check that decides a name looks like Anthropic's is not described, only the message shown.
