If it could be done with 30 cents of Haiku calls, maybe it wasn't a complicated enough project to provide good signal?

In that case a $12 program is probably too big to meaningfully review. Probably better to have smaller chunks you can review instead of generating one really large program in one shot.

Fair point. I could try with a harder problem. This still does not explain why Claude Code felt the need to use Opus, and why Opus felt the need to burn 12$ or such an easy task. I mean, it's 40 times the cost.

I'm a bit confused actually, you said you used Claude Code for both examples? Was that a typo, or was it (1) Claude Code instructed to use a hierarchy of agents and (2) Claude Code allowed to do whatever it wants?
