Show HN: A Claude Code skill to analyze your chess games (github.com)

A new Claude Code skill has been introduced that transforms your chess games into in-depth, accessible post-mortem analyses. This tool generates plain-language explanations of your mistakes, corroborated against the powerful chess engine Stockfish, and produces a narrated video that walks you through the entire game. By combining a think-aloud recording of your thought process during the game with the game's PGN data, Claude Code can accurately align your thoughts with your moves, enabling a personalized and comprehensive analysis. This development is significant for the AI/ML community as it bridges the gap between complex engine evaluations and human understanding. Traditional Stockfish outputs can overwhelm players with numbers and variations without offering insight into their decision-making. Claude's ability to interrogate Stockfish in human terms—addressing specific player questions and errors—enhances learning opportunities for chess enthusiasts. The system requires players to engage actively with their games, making it suitable for in-depth study rather than quick evaluations, and presents an evolving approach to AI in educational contexts, where personalized learning experiences are increasingly paramount.
