What they did

brumar wrote Claude Code skills that pull a game, run Stockfish, read his live audio or text notes, and produce a commented video explaining what he was thinking and what he missed.

How it went

He says it works but takes about an hour per game, and the last game would have cost about $15 at API prices. He found it more memorable than clicking through engine lines. The skills are open source on GitHub.

Worth knowing

Token-heavy, so check your quota. He noticed little sycophancy because Stockfish anchors the analysis.
