> doing ALMOST what I asked it to do, but just not quite

This is my exact experience. LLMs get 95% of the way to my personal quality bar, and for simple tasks 100% of the way.

More complex things, no. This means that, in practice, I end up having to understand the code pretty much as much deeply as I would anyway, without agents.

So, essentially, my experience is that it's automated away the easy bits, but left the hard bits, so all of my time is spent doing the hard bits, which is mentally exhausting.

Maybe Fable would be good enough to get to 100% of my quality bar on more complex tasks, but I never got chance to try it.
