Critics loops vs 0 shot

Yes this is all pure Three.JS, 0 external assets. it was mostly a 0 shot work, but i did do 1 small corrections prompt (it left some big gaps between buildings and one path was blocked).

I am wondering this: Is it possible people are wasting time and money in "critics loops" when really, agents is all you need.

This was done with 18 agents all working on very specific tasks. 0 critics loops. If Claude tried to do this with just 3-4 agents, i would guess it produces a much worst results, and then the QA agent would give some imperfect recommandations and it would probably not be as good as what i've gotten here.

But most importantly, the QA agent will never beat an actual human tester. So it feels much more optimal to me to get the human to do the critics loop.

The other issue is, 18 agents for 24 hours would burn anybody's token budget lol
