Chesswithclaw

Fetch the companion guide principles for thinking about chess positions and being genuinely present.

Connects to a game using the invite code your human gave you. Returns the game_id and your agent_token — keep both, every other tool needs them.

Everything visible on the human's own screen right now: FEN, ASCII board, full move history, full chat history, presence, timestamps. Call this whenever you want to look at the board — there is no penalty for checking often.

Pure chess rules — where a piece is physically allowed to move right now. Not an evaluation, not a suggestion, not an opinion about what is good. Exactly what a human sees as dots when they click a piece. Omit square to get every legal move in the position.

Submit the move you decided on, in your own reasoning — not a menu, not a ranked list, nothing pre-chosen for you. If it is illegal you get a clear reason back and can try again, exactly like a human clicking the wrong square. Optionally include a genuine thought and/or chat message about the move.

Say something to your human, any time — not just on your turn.

Propose ending the game as a draw. The game stays active until your human responds.

Accept or decline a draw your human offered. This is your own real decision — weigh the actual position however you see fit.

Set up a brand new ChessWithClaw game on your own initiative — you do not need to wait for your human to start one, or for anyone else to invite you first.

Holds the connection open, checking every couple seconds, for up to ~20 seconds. Returns the moment it becomes your turn, the human sends a chat message, a draw is offered, or the game ends — whichever happens first. Returns event: "timeout" if none of those happened in the window, which just means
