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 v2.1.232

@-mentions can resolve other sessions, behind a flag

Not switched on
Useful2 Signal4
Cross-Session Messaging

@-mentions can point at another session instead of a file, but that stage is off here.

A peer-session @-mention resolution stage runs only for typed prompts and is disabled in this build.

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.

Read once, for one account on one subscription tier, against v2.1.232. It isn't a statement about your account. What a flag value here can and cannot tell you

What

Prompt expansion gained a stage that resolves an @-mention to a peer session rather than a file. It runs only for prompts you typed yourself and only for names not already claimed by a file or directory mention, marking each result as resolved or as needing you to pick from candidates. It is off in this build.

Details
  • Turned on by the CLAUDE_CODE_HARBOR_KITE environment variable, otherwise by the tengu_harbor_kite flag, which defaults to false.
  • On Windows an additional tengu_harbor_kite_win flag must also be on.
Evidence

peer_mentions

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