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.

Idle notices between sessions can carry the sender's permission mode, switched off here

Cross-Session Messaging

Idle notices could tell the other session whether you are in bypass mode, but that stamp is off.

Permission-mode stamping on cross-session idle notices sits behind tengu_harbor_kite_mode_emit, which falls back to false.

Feature flag
tengu_harbor_kite_mode_emit 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.

What

Messages sent between sessions on the same machine when one goes idle can now be stamped with the sending session's permission mode, as bypass or prompting. The stamping helper returns nothing unless the gate tengu_harbor_kite_mode_emit is on, and it falls back to false in this build, so no mode is attached.

Details
  • The mode comes from the inbound session's current permission mode, falling back to the mode recorded when the session was disconnected.
  • The receiving side already reads this field on both idle notices and idle-notification requests.
  • The same gate covered the notification-request case in 2.1.235; this extends it to idle notices.

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