What
When Anthropic's API refuses a request, the error message Claude Code shows now includes a "Message ID:" line after the existing "Request ID:" line. Before, only the Request ID was shown.
Why
If you think a refusal was a mistake, you now have a second ID to include when you report it, which makes the case easier to find.
