Good response, but more practically, when you are developing a project you allow the agent to do many things on that VM, but when you deliver code it has to actually pass tests. The agent working is not being tested live, but the code delivered is tested before use. I think tests are the core of the new agent engineering skill - if you can have good tests you automated your human in the loop work to a large degree. You can only trust a code up to the level of its testing. LGTM is just vibes.
