What
/design-login authorizes design-system access for /design-sync with your claude.ai account, usually by sending you through your web browser. When that browser flow fails because the authorization code was refused, Claude Code now reports a separate failure for it and shows the error's own message.
Before, this case was treated like any other failure and showed the generic message telling you to run /design-login again with the manual flow.
Why
If your code is refused, you now see what actually went wrong rather than a general failure notice.
