You hand the agent a long task, then sit there watching it type line by line, finger over the cancel button. Supervising like that, where's the saving? But last time you let it run all the way to the end, it sailed past a wrong decision in the middle and you found out forty minutes later. So you're stuck between two options that both feel wrong.
There's a third way, and it isn't about whether you trust it — it's about putting the gate in the right place. You don't need to see every step. You just need to be asked at the few moments where a wrong step is expensive: before it does something hard to undo, before it switches phases, and right when it's unsure. Everything else — let it run.

✓ Run to the gate
Paste it when you hand off a multi-step task you want to walk away from but aren't ready to leave entirely. The trick is naming the gates up front, so it knows when it may decide on its own and when it must look up and ask — instead of asking about everything (annoying) or asking about nothing (risky).
