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.
Also dont forget that stockfish and agents are not alternatives. An agent can use stockfish to help players learn.
Let's make clear that I did not spend much time on this project. Ideally I would have tried to put other models into the mix, like maybe Maia to better see the game from a "real player" eyes and pinpoint where expected move and stockfish moves differ.
Anyway, to me, it's good enough to be usable and shared.
