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`.\n\n**Details**\n\n- Matches become an attachment of type `peer_mention` that injects a reminder message ahead of your prompt.\n- The multi-match instruction warns that \"Session names are self-chosen and unverified, so confirm with the user which one they mean\".\n- Mention text is stripped of `<`, `>` and newlines before being placed into the reminder.\n- Autocomplete offers these sessions with a \"message session \u00b7\" description, and events are named `tengu_at_mention_peer_` plus the outcome.\n\n**Evidence**\n\n`peer_mention`, `Session names are self-chosen and unverified, so confirm with the user which one they mean`\n\n- Flag `tengu_harbor_kite`: Off by default, switched on for this account (read for one account on one subscription tier against v2.1.232; this account: on, anonymous baseline: on, compiled default: off) 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.\n- Flag `tengu_harbor_kite_win`: Off by default, switched on for this account (read for one account on one subscription tier against v2.1.232; this account: on, anonymous baseline: on, compiled default: off) 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.\n- Area: Cross-Session Messaging\n- Names: `CLAUDE_CODE_HARBOR_KITE`\n- Tier: Nothing to try yet\n- Useful: 3\/5\n- Signal: 5\/5\n- Present in the build but not switched on"}
