What

One request Claude Code sends to a remote server no longer carries a User-Agent header. That header is the line in a web request that identifies which program sent it. The request still sends:

  • the anthropic-beta header
  • the x-organization-uuid header
  • the trusted-device token
Why

Anything on the server side that logs or recognises clients by their User-Agent will no longer see it on this request.

How sure we are
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubtIt is not settled exactly which request this is, though it appears to be the one that creates a remote bridge session.
