Source Intelligence

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.

Session Messaging

Messaging a session on another machine now tells you why no reply can come back.

What

Sending a message to a session running on another machine now explains which of two reasons makes the exchange one-way: Remote Control is not connected on this machine, or there is no reply address here.

Evidence

no reply address here

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