What

The instructions Claude gets about a machine attached to your session were rebuilt around three sync modes: two-way, upload-only and off. In upload-only mode Claude is now told that edits made in the session are not carried back to the machine, and it is told which file tools act locally and which act on the machine.

Details
  • Wording branches on the machine's declared sync mode into "here", "refreshed" and "machine" phrasings.
  • New timing rules: your local changes reach the machine at the end of a turn; files a remote command creates only arrive with your next message; git-ignored files never cross.
  • Emitted whenever machines are attached to the session.

- Results say where each call ran.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
