What probably matters to youSection of the release

Full @-mention session messaging across local, cloud, bridge and team sessions is built but tengu_harbor_kite defaults false.

What

Typed prompts are scanned for @-mentions matching other live Claude sessions, found via local sockets, cloud sessions, bridge sessions and a team file. A match tells Claude to message that session using its exact "name [ref]" token; when several sessions share a name, Claude is told to ask you which you meant first. Off by default: the cross-session messaging feature flag tengu_harbor_kite defaults to false, CLAUDE_CODE_HARBOR_KITE forces it on, and Windows additionally requires tengu_harbor_kite_win.

Details
  • Matches become an attachment of type peer_mention that injects a reminder message ahead of your prompt.
  • The multi-match instruction warns that "Session names are self-chosen and unverified, so confirm with the user which one they mean".
  • Mention text is stripped of <, > and newlines before being placed into the reminder.
  • Autocomplete offers these sessions with a "message session ·" description, and events are named tengu_at_mention_peer_ plus the outcome.
