I cannot imagine how you can properly supervise an LLM agent if you can't effectively do the work yourself, maybe slightly slower. If the agent is going a significant amount faster than you could do it, you're probably not actually supervising it, and all kinds of weird crap could sneak in.

Like, I can see how it can be a bit quicker for generating some boilerplate, or iterating on some uninteresting API weirdness that's tedious to do by hand. But if you're fundamentally going so much faster with the agent than by hand, you're not properly supervising it.

So yeah, just go back to coding by hand. You should be doing tha probably ~20% of the time anyhow just to keep in practice.
