What's Wrong?

We've got Claude Code Desktop configured via AWS Bedrock (3P inference mode) and it works great, however the CLI does not expose the /desktop command to eject a CLI session to the desktop app, even though theoretically it should work.

What Should Happen?

/desktop ejects a AWS Bedrock CLI CC session to Claude.app
