A couple/few years ago people were trying to do agents by just putting the LLM in a loop and letting it go, and it was just awful and didn't work at all. I think a bunch of things had to happen over the course of 1-2 years to get to coding agents being a real, useful thing: models had to get quite a bit smarter/cheaper/faster, models had to get good at tool use, and they needed to be executed in well-built harnesses with good tools available.

This feels like the same thing. Too early, but we're definitely headed in the direction of finding ways to use more tokens to get more mileage per prompt.
