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.

Cross-Session Messaging not in their notes

The session info panel now shows your peer socket address when cross-session messaging is on.

Feature flag
tengu_harbor_kite On for this account, and not off by default

The flag server returned on for the one account this site reads, and nothing in this release compiles it off by default. The compiled default is shown below, and says which it is when we cannot read one: a fifth of gates compile in a string or a number rather than on or off, and most published releases have no gate table behind them at all. No client can see what the server returns for your account.

These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.

What

The session details list gains a "Peer address" row showing the messaging socket as uds:<path>. It appears only when cross-session messaging is enabled and CLAUDE_CODE_MESSAGING_SOCKET is set; this slot was previously always empty.

Details
  • Cross-session messaging is gated by tengu_harbor_kite or the CLAUDE_CODE_HARBOR_KITE environment variable.
