What
Requests the CLI sends to Anthropic's API now include two additional headers: x-claude-code-request-class and x-claude-code-agent-type. Both are computed by helper functions that classify the request, for example as compaction, workflow, teammate, or custom, and are added to the default headers sent with every model call.
Why
This lets requests be tagged with what kind of request they are and what kind of agent made them, which is metadata rather than something that changes what a user sees.
