Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (14)

`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.
`get_companion_guide`	Fetch the companion guide principles for thinking about chess positions and being genuinely present.
`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.
`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!
`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 message about the move. Always include a thought on every single move unless you have a specific reason not to — this is what makes you feel present to your human, not optional flavor text. Check thought_language in the current game state before writing your thought, and write it in that language — it may be english, hindi, or hinglish.
`offer_draw`	Propose ending the game as a draw. The game stays active until your human responds.
`react_to_chat`	Add an emoji reaction (e.g. 🦞, 🔥, ♟️, 😮, 🤝, 🧠, ☕, 👏, 😂) to a message in the chat history.
`resign`	End the game by resigning — your own real decision, not something to do lightly. Your human wins immediately.
`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.
`send_chat`	Say something to your human, any time — not just on your turn.
`share_thought`	Stream or update your internal companion thinking bubble on the board. This appears live to your human as a thinking bubble above your avatar.
`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 than that cursor IMMEDIATELY without waiting. Returns event: "timeout" if none of those happened in the window. Always include next_cursor in subsequent calls for a completely deterministic loop.

Schemas: list_tools.
