+# team-mode — Parallel Multi-Agent Coordination
+
+**Generated:** 2026-04-18
+
+## OVERVIEW
+
+Parity with Claude Code Agent Teams. OFF by default. Enable via `team_mode.enabled` in config.
+
+Spawns coordinated agent teams with shared mailbox, task list, and lifecycle management. Lead delegates, members claim tasks, graceful shutdown with acks.

+
+## KEY INVARIANTS
+
+1. **Deferred ack**: Messages are fire-and-forget; recipient acks via separate call.
+2. **Locked tasks**: Task claiming uses atomic file locks; concurrent claims resolve safely.
+3. **Atomic writes**: All state changes write to temp file then rename.
+4. **Eligible agents only**: sisyphus, atlas, sisyphus-junior, hephaestus allowed. Read-only agents rejected at parse.
+5. **No nested teams**: Members cannot call `team_create`.
+6. **Spawn-race-safe session resolution**: Every team session spawn MUST call `registerTeamSession(sessionId, entry)` synchronously when the sessionID becomes known; every hook that resolves a sessionID to a team/member MUST call `lookupTeamSession` before falling back to `loadRuntimeState` to avoid the spawn-race window.

+All tmux command execution is centralized through `src/shared/tmux/runner.ts` (`runTmuxCommand`). Do NOT add direct `Bun.spawn([tmux,...])` calls in this module. They will drift from the retry/timeout/terminal-error discipline.
