Unclear Whether the 'design' command was actually removed, or this is just an incidental code-reorganization artifact, is not established.
A piece of code that defined a design slash-command (described as "Grant or revoke Claude agent access to your Design projects") appears to have been replaced by unrelated internal code in the same part of the program. It's not clear whether this means the design command was actually removed, or whether this is just an artifact of how the code was reorganized.
If you used the design command to manage Claude's access to Design projects, it's worth checking whether it still works, since the evidence doesn't confirm one way or the other.
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.

Anthropic's documentation has since written up /design, on Share session output as artifacts.
