Register an agent and ensure its live tmux pane exists. Not required before send/broadcast — they self-provision — but useful to pre-create a pane before anyone messages that agent.

Send a message to one agent. Appears instantly in the recipient's tmux pane (push-based, no polling) and is recorded in their queryable history.

Send a message to every registered agent (except the sender). Each recipient's pane updates instantly.

List every agent registered in the mesh.

Fetch an agent's structured message history (source of truth — the tmux pane is just a live view of the same data).

Spawn an interactive Claude Code session in a tmux pane as the given agent. From then on, tmux_send to that agent types the message directly into that chat — it appears on screen and Claude responds, no polling and no human input.

Get the shell command a human can run to attach a terminal directly to one agent's live pane.
