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.

Claude Code v2.1.91

Peer Session Messaging

What

When another Claude Code session sends a message while you're working, it now appears with contextual framing that helps Claude understand the message source.

Details
  • Messages from peer sessions are labeled: "A peer session sent a message while you were working"
  • Claude is instructed: "This is from another Claude session, not your user. After completing your current task, decide whether/how to respond."
Evidence

Peer session notification framing (search for "A peer session sent a message")

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