Unclear What Claude Code does differently when this check matches is not shown.

What

When you use Claude through Amazon Bedrock, Claude Code checks failed requests for model errors. That check used to match only messages mentioning a model ID. It now also matches when a classifier, an automatic content check, returns a refusal.

Why

More Bedrock failures may now be treated as a model error.
