Unclear What the serveOnly option actually changes about headless cloud behavior is not stated.

What

The headless cloud-session bootstrap path (used when running the CLI to create or attach to a session on Anthropic's cloud) now supports a serveOnly option:

  • The create path calls a renamed runHeadlessCloudCreate function and passes { serveOnly: C.serveOnly } into runHeadlessCloudAttach.
  • A new session-opener path with entry: "attach" accepts the serveOnly option, and when set, swaps in a reduced feature set instead of the normal full feature set.

Why

This gives a way to attach to or create a headless cloud session with a minimal, serve-only feature set rather than the full normal feature set.
