I'm an ok chess player (roughly OP level) and slightly more experienced claude code user.
I tried to use claude to analyze my games using stockfish - this is not a problem claude is good at.
I spent few hours (however admittedly around opus 4.8) with claude on this and it was unable to use stockfish in any useful way.
I think if the skill created by OP works then it's a real contribution. I'll give it a try.
Thanks for trying it out! I'd be happy to see how it goes for you and compare our implementation notes if the analysis you got is not too bad.
