-The agents have no knowledge of each other — the script holds all the routing logic.
+The script initializes the routing, but agents can discover other sessions
+via `session/idx` and write to their `prompt` files directly — coordination
+is a shared filesystem, not a master-slave topology.
 Each agent can use a different `agent=`, `backend=`, or `model=`.
