What
/design-sync has new messages for a design system that has moved to Claude, or is in the middle of moving there. They tell you that /design-sync can't send updates to Claude yet. They also include an "Open it in Claude:" prompt that points you to where the design system now lives.
Why
If your design system has moved, you see a clear notice that /design-sync can't update it yet, along with a way to open it in Claude.
One source agreesOne thing we can check says the same as this entry.
Anthropic's release notes agreeImproved /design-sync to say up front when your design system has moved to Claude, and stop before building instead of failing at upload
