/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-loginis 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.
