What
Claude Code now sends three new HTTP headers on some requests: x-claude-code-compaction, x-claude-code-context-compacted, and x-claude-code-prev-tool-durations. The last one carries a compact, size-limited list of recent tool names and how long each took to run. These headers are only attached when the connection is related to a Remote Control bridge session.
Why
This lets the server side of a bridge connection see timing and compaction (conversation-history trimming) information about the session without the client having to be asked for it separately.
