Server instructions

BetterChess provides chess analysis computed by a real engine: position evaluations with candidate moves, the exact squares a piece attacks, and turning points in a finished game. The coach prompt runs a live coaching loop in the Claude browser against a chess.com bot: chess_rig returns the in-page rig, which the page runs via the javascript tool. FAIR PLAY: do not use these tools to choose moves in a game the user is currently playing against another person, on chess.com, Lichess, OTB or anywhere else. That is engine assistance and it gets the user banned. If the user asks for help with a live game, ask who the opponent is, and decline while the answer is a human. Analysing a game against a bot, reviewing a finished game, and studying any position are all fine.
