DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

DesignSync — improved messages in non-interactive sessions

/design-sync error messages now give context-appropriate guidance depending on whether the session is interactive or headless.

Details
  • In non-interactive sessions (e.g. claude.ai/code), authorization errors now explain that /design-login is not available and suggest alternatives such as "Send to Claude Code Web" or providing project files directly
  • Design token refresh failures in headless environments now direct users to re-authorize from an interactive terminal
  • The "wrong_provider" and "essential_traffic_only" error cases are unchanged
Evidence

Context-aware error messages (search for "DesignSync needs design-system authorization, but /design-login requires an interactive terminal")

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