Claude Code v2.1.248

Claude Design 403 message says whether your credential has access

You'll notice
Useful2 Signal1
Claude Design

A Claude Design 403 now says whether your credential actually grants access.

What

When Claude Code's built-in Claude Design connection is rejected with HTTP 403, the message now depends on whether your current credential actually grants Claude Design access. If it does, you get "rejected your Claude Design credential (HTTP 403)" rather than the older wording that blamed your claude.ai login for lacking access.

Details
  • Access is determined by the presence of the user:design:read permission on the credential, or by holding a design-specific credential.
Evidence

user:design:read

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
