A Claude Code skill that runs chess post-mortems with Stockfish

Show HN: A Claude Code skill to analyze your chess games

brumar released a Claude Code skill that plugs Stockfish into AI-driven chess post-mortems. You upload a PGN file, and Claude calls Stockfish to annotate every move, then produces an annotated PGN, an HTML replay board, and a narrated video. The toolchain is Bash scripts with Python and ffmpeg dependencies—still early, just over 10 stars.
