yeah very few months I try to have it “just do magic” again and I re-learn the lesson. Like, I’ll just say “optimize this shader!” and plug it in blind.

It doesn’t work. The only way it could is if the LLM has a testing loop itself. I guess in web world it could, but in my world of game dev, not so much.

So I stick with the method I outlined in OP and it is sometimes useful.
