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.

Clearer messages when sending to another session

Session Messaging

Sends to another session now report a rewritten message separately from an outright denial.

What

Messages sent to another session now go through the permission handler, which may rewrite them; a rewrite is reported separately from an outright denial. One-way sends distinguish "Remote Control is not connected" from a remote container that has no address to reply to.

Details
  • The recipient is passed to the permission handler as a label, so the ask names who the message is going to.
  • Sending to an unnamed remote session adds a note that the receiver can only answer using the address carried on the message.
Evidence

this session has no reply address

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