In my experience, it’s even more effort to get good code with an agent-when writing by hand, I fully understand the rationale for each line I write. With ai, I have to assess every clause and think about why it’s there. Even when code reviewing juniors, there’s a level of trust that they had a reason for including each line (assuming they’re not using ai too for a moment); that’s not at all my experience with Codex.

Last month I did the majority of my work through an agent, and while I did review its work, I’m now finding edge cases and bugs of the kind that I’d never have expected a human to introduce. Obviously it’s on me to better review its output, but the perceived gains of just throwing a quick bug ticket at the ai quickly disappear when you want to have a scalable project.
