Accelerator Checkers(Draughts)

Use to start a playable English/American 8x8 checkers game inside the conversation. Call this tool when the user asks to play checkers, wants a board rendered in chat, or wants to begin from a specific structured position. If no initialState is provided, the tool creates a fresh standard game where the user controls the dark side and moves first. If an initialState is provided, it must already be a normalized board description with square numbers 1-32, the side to move, and explicit owner/kind values for every piece. Starting a new game replaces any existing game for the current session. Use this tool for starting positions only. Do not call it to continue an existing game after someone has already moved; use makeMove for that. Do not invent illegal positions, duplicate squares, or unkinged men on promotion rows.

createGame

Use to apply exactly one legal move to the current session's English/American 8x8 checkers game created by createGame. Call this tool after either the user or the model has chosen a move path from the current board state's legalMoves list. The input must include the player making the move and the full move path, including every landing square for a multi-jump capture. The tool validates turn order, forced captures, promotions, and terminal conditions, then stores the updated state on the server and returns the next authoritative board. When the user has just moved in the widget and the game is still live, call this tool again for player 'model' using one of the returned legal move paths. Do not invent a move that is not present in legalMoves, do not omit intermediate jump landings, and do not use this tool to start a new game.
