When I was in grad school I graded homework for first year math classes, and the thing about math homework is that the perfect homework takes almost no time to grade.
It's the bad, semi-coherent submissions that eat up your time, because you do want to award some points and tell students where they went wrong. It's the Anna Karenina principle applied to math.
Code review is the same thing. If you're sure Claude wrote your endpoint right, why not review it anyway? It's going to take you two minutes, and you're not going to wonder whether this time it missed a nuance.
Typically in engineering you don't know what you're doing. If you're sure of what it should look like going in, you're more of a technician. I think most people coding have no idea what they're doing to a large extent- not many people can do the same rote work for years straight.
