Just added! I had Opus 5.5 look at them, not a perfect way to score them but it's close-ish -- Best would be a ELO, where people play both and rank a winner, but I don't know if people want to bother doing that.

Pretty cool. Using Opus as a judge should be more than good. Interesting to see more stats like the result file size too, but the grading criteria are maybe a bit skewed towards UX. Would like to see more code quality.
