It sounds to me like you're arguing against this point in particular.
More power to you. I'd like never to work at a place that sanctions slop-validated-slop.
If you find your agent sucks at programming and has zero taste for good design, then that's arguably a 10x of the operator.
I'm quite pleased with the quality of programming and design that I'm able to achieve with the processes I do with agents.
I've certainly noticed that when I watch a junior use AI they've produced nothing but the most intolerable slop man has ever seen. And I've seen principles and architects produce one shots that are such shining examples of quality engineering that they remain nothing more than goals to me.
Most of them exited this industry before their career was over.
Good luck to you
