It started as an experiment: can Claude play chess properly if it uses vision instead of PGN notation? Somehow it can.
The next experiment was to see whether Claude + Stockfish could explain a game. Somehow it can too.
A few sessions later, I had a system that takes my live audio notes (or text, for that matter) and a vague instruction like "analyze my last lichess game", and gives me a commented video of the game. The result is not perfect and it takes time to deliver (an hour or so), but for me it is a much more pleasant and memorable experience than clicking around Stockfish branches. It burns tokens, so make sure you have enough quota. From the session logs, the last analyzed game would have cost around $15 at API prices.
The fact that it reflects on my own thinking during the game makes it interesting from a teaching point of view, so I thought it was worth sharing.

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.
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.
I've been using Elogram (https://elogram.gg/, made by a friend), which gives interpretability by showing how difficulty of a position changes with elo.

Did you write the skills (text, and code) all by hand, or are those prompt outputs?
It took multiple sessions to get to this result. At first I only generated annotated pgns and standalone html page inspired by lichess. The video generation was the cherry on top, it took few iterations too to fix issues and add markers and arrows. I only use consume the generated video these days, for the moment.
Also, you seem to have written the actual SKILL.md prompts themselves with AI? I don't know what to say that's insane, at least write the prompts? This idea of asking chatgpt to write the prompts for you is beyond lazy. Then presenting it as a project or tool of value to share to others is delusional.
Sorry for being harsh
"The fact that it reflects on my own thinking during the game makes it interesting from a teaching point of view, so I thought it was worth sharing." As AI the premium sycophantic scammer does
"but for me it is a much more pleasant and memorable experience than clicking around Stockfish branches"
And SO much less effective than doing the harder, more tedious feeling work
For the sycophancy, I can say I did not feel that at all. When stockfish says your move suck, claude would have a hard time saying the opposite (no "you are absolutely right" when I am not).
Because lengthy difficult cognitively intensive labor is required for the brain to actually change its structure and connections
Nonetheless, as many do, I often ask AI to explain me stuff. I know it's not perfect, but it's convenient, it's a trade-off to make.
