DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Cross-session send prompts distinguish cloud from Remote Control peers

You'll notice
Useful3 Signal0
Cross-Session Messaging

Prompts for messaging another session now say whether the peer is cloud or Remote Control.

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session on another machine (cloud or Remote Control)", and error text says a session "may have ended" and either "or been archived" (cloud) or "or disconnected".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.
