## Tools (as reported by the server, not verified)

- `get\_opening\_guide`: Look up a chess opening by name or slug \(for example "London System", "Caro-Kann" or "sicilian-defense"\) and return Chessigma's guide to it: the main line in SAN, a short summary, up to four key variations with the idea behind each, the strategy for each side, strengths and weaknesses. Full guides e
- `identify\_opening`: Identify the chess opening of a move sequence, given as SAN movetext \("1. e4 c5 2. Nf3 d6"\) or a full PGN. Returns the ECO code and name from a catalogue of about 3,700 named lines, how many half-moves \(plies\) followed known theory from move one, the first move that left it, a link to Chessigma's tr
- `analyze\_position`: Read a chess position from a FEN and return facts computed by the rules alone: side to move, status \(normal, check, checkmate, stalemate or insufficient material\), every legal move in SAN, the material count \(pawn 1, knight 3, bishop 3, rook 5, queen 9\) and the opening name when the position is a ca
- `analyze\_game`: Summarize a chess game given as a PGN or as plain SAN movetext: players, result, number of plies, the opening and how long it followed theory, how the game ended \(checkmate, stalemate, draw by rule, or unfinished or resigned\) and the final position. Returns a link that opens the whole game on the ch
- `review\_online\_game`: Turn the link of a public Chess.com live game or a Lichess game into a chessigma.com link that imports the game and opens a move-by-move review, computed by Stockfish in the user's browser. Nothing is fetched when this tool runs: the game is read from Chess.com or Lichess only when the user opens th
- `get\_daily\_puzzle`: Get Chessigma's daily chess puzzle: today's by default, or a past day's via date \(YYYY-MM-DD, from 2024-01-01 to today in UTC\). The position \(fen\) is given with the solver to move, after the opponent's last move. The solution is in SAN, with the solver's moves at even indexes and the opponent's repl
- `calculate\_elo`: Estimate a player's new Elo rating after a single game with the Elo formula. Pure arithmetic, no chess engine. The system field picks a K-factor default for FIDE, Chess.com or Lichess, but the result is an Elo estimate: Chess.com and Lichess use Glicko ratings, so their real rating changes differ.
