What
The cloud side could already ask the machine to sync files. Claude Code on the machine now handles those requests. It pulls the session's latest file changes into the local checkout and, when asked, sends the checkout's state up. The session calls this around the commands it runs on the machine; you do not call it yourself. A sync job can be rejoined by its id, and up to 16 jobs are tracked.
Calls are refused when:
- the sender is held back under the trusted-device policy, reported as
unattested_request - no sync engine is running
- the folder is not syncing
- too many calls are already running
Why
It completes two-way file sync between a cloud session and the machine it is bound to.
