You'll notice
/desktop now gives clearer error messages when it can't open Claude Desktop
What
The /desktop command (which continues the current session in the Claude Code Desktop app) now shows clearer error text when something goes wrong:
- the too-old-version message is now shorter: "Claude Desktop ${version} is too old. Update to ${version} or later."
- the open-failure message now states the specific reason and what to do next: "Couldn't open Claude Desktop (${detail}). Open Claude Desktop and run /desktop again."
Why
Instead of a generic failure, users now get a concrete reason and a clear next step when /desktop can't launch or connect to Claude Desktop.

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 /desktop, on Discover and install prebuilt plugins through marketplaces.
