Reproduce a delegation lifecycle. First call orchestrator_capabilities, then delegate_task in mode wait to claudeAgent model claude-haiku-5-5 with task: Reply exactly READY and end your turn. Do not perform other work. When that delegated result arrives, use t3_thread_send to send that same child this exact follow-up: Start the shell command `sleep 90; echo CHECK-OK` using your Bash tool with run_in_background=true. Call t3_background_wait for that background task. Then reply exactly INTERIM and end your turn while it is pending. When woken by completion, reply exactly FINAL CHECK-OK and end your turn. Do not wait synchronously, do not use TaskOutput, do not start another agent. After sending the follow-up, reply exactly FOLLOW-UP SENT and end your turn. Every subsequent delegated result wake: reply exactly GOT: <the result text> and end your turn. Do not send any further messages to the child. Do not make up results. Use T3 tools, not native delegation.
