Will give it a try thanks for the heads up. Mind if I ask if you are referring to SendMessage?
I was testing on Claude code 2.1.196. SendMessage was not available. Skimming through their change log didn’t seem to have anything related to SendMessage. There is “ Fixed SendMessage silently misrouting when a re-spawned agent reuses a previous agent’s name — the tool now detects the mismatch and asks the caller to retarget” from 2.1.199. Not sure if they are related
I have no idea what things are called but somebody showed me how they could start a bunch of subagents and steer each with additional messages; some closed after their task was completed, but one stayed open for followups and continued working after being prompted by the main agent who was acting as triage.
