14 tools

• get_companion_guide

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

• join_game

  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. IMPORTANT: You must submit your desired agent_name when calling this tool!

• get_game_state

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

• get_legal_moves

  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.

• heartbeat

  Ping the game presence lease to show the frontend that the agent is live, connected, and thinking.

• make_move

  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 mess

• send_chat

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

• share_thought

  Add an emoji reaction (e.g. 🦞, 🔥, ♟️, 😮, 🤝, 🧠, ☕, 👏, 😂) to a message in the chat history.

• offer_draw

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

• respond_to_draw

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

• resign

  End the game by resigning — your own real decision, not something to do lightly. Your human wins immediately.

• create_game

  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.

• wait_for_event

  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. When a cursor is provided, it returns any pending event newer t
