What
The permission prompt for messaging another session now says which kind of peer you are reaching and makes clear how the message is attributed on arrival.
Details
- The prompt branches on the peer's
via, saying either "cloud session" (running in the cloud) or "Remote Control session" (on another machine). - Both texts now spell out that the message arrives marked as from another Claude session, not from its user.
- Peer-listing and error paths were updated to match: a peer-name collision now reads "a Claude session on another machine (cloud or Remote Control)", and error text says a session "may have ended" and either "or been archived" (cloud) or "or disconnected".
Evidence
It reaches the receiving Claude (running in the cloud) via Anthropic's servers as a cross-session message — marked as from another Claude session, not from its user.
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
