A subagent is a helper Claude starts to do part of a job. It can use this tool to deliver its full report back to the agent that started it, and gets "Report delivered to your caller." in reply. The tool now:
- refuses an empty report.
- refuses a second delivery after the first.
- returns an error when it is not switched on for that agent.
It is only offered when a server-controlled switch allows it and the safety check for auto mode is working in its reviewing role. With nothing from the server, the switch falls back to off. Delivering a report can still end the agent's turn, and that switch falls back to on.
This changes how a subagent's results reach the agent that started it, and the report passes through the safety check on the way.
