About the project

A set of Claude Code skills that turn a chess game into a post-mortem: Stockfish analysis of every move, annotated PGN, HTML board, and a narrated video. It can also use a recording of the player's think-aloud during the game.

Useful for

Analyze your rapid game with plain-language explanations checked by Stockfish

Align a think-aloud audio recording to moves using PGN clock times
