What

A subagent is a helper agent the main session starts to handle part of a task. When it finishes, it sends back a report. Its instructions used to say to send the report and then stop. They now say that sending the report ends the run, so it should be the last thing it does.

Why

This is a small change to how subagents wrap up and hand back their results.
