What
When you add a plugin marketplace from a url source, Claude Code now hardlinks the downloaded catalog into the cache instead of always renaming it, and:
If a marketplace with that name is already registered from a different source, the add is refused with an error instructing you to run /plugin marketplace remove first.
If finalizing the cache fails for another reason, a more explicit error is shown, explaining that adding a marketplace will never silently replace an existing one with the same name, and how to recover.
Why
This prevents one marketplace from quietly clobbering another that happens to share a name, which could otherwise replace plugins you already trust without warning.
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 sinceAnthropic's documentation has since written up /plugin marketplace remove, on Error reference.Marketplace "acme-tools" is already added from a different source (github:acme/plugins). To use this source instead, remove that marketplace first with /plugin marketplace remove acme-tools.errorssee the edit
How sure we are
Two sources agreeTwo things we can check say the same as this entry.
Anthropic's documentation agreesAnthropic's documentation has since written up /plugin marketplace remove, on Error reference.
Anthropic's release notes agreeAdded /plugin install <plugin> --marketplace <source>, which offers to add the marketplace before installing the plugin
