In the example I gave, it was just porting the same view code from one framework's way of writing view code to another. It's a one-off task involving hundreds of different views.

There's zero technical challenge, almost no logic, super tedious for a human to do, not quite automatable since there could be any kind of code in those views, and it's very very unlikely that the LLM gets it wrong. I give it a quick look over, it looks right, the tests pass, it's not really a big deal.

And one nice thing I did as well was ask it to "move all logic to the top of the file", which makes it -very- easy to clean up all the "quick fix" cruft that's built up over years that needs to be cleaned up or refactored out.

In those cases the file might indeed need more time dedicated to it, but it would've needed it either way.
