Capabilities

Tools 4

create_game

Set up any game to play in this chat: board games, card games, dice games, word and guessing games, mysteries. Describe it with the building blocks below, or pass starter for a ready one (tic-tac-toe, four-in-a-row, gomoku, checkers, reversi, crazy-eights, go-fish, twenty-one, pig, sea-battle, hangman, twenty-questions). The server keeps the board, deals and hides cards, rolls dice and enforces turns, so the player can trust the game. The player gets an interactive board in the chat (and a link to play in a browser or invite friends). Returns game_id and agent_key; keep both for get_state and take_turn. You run the rules that aren't built in.

Discovered
get_state

What your seat can see now: the board, your hand, public piles, scores, dice, secrets you hold and the recent log. Call it when the player says they've moved or it might be your turn.

Discovered
show_board

Show the interactive board in the chat again, for example after a long conversation or when the player asks to see it.

Discovered
take_turn

Apply one or more actions for your seat, all or nothing: if any action is illegal, none happen and you get the reason. Usually end with end_turn. Action types and fields: - place {at: "B3"} or {column: "D"} with gravity; optional label, shape (disc, square, ring, star, diamond), color, kind, owner - move {from: "B3", to: "C4"} or {piece, to}; moving onto another player's piece takes it; optional label, kind - edit {at, owner?, label?, kind?, shape?, color?}: change a piece in place (flip, crown) - remove {at} or {piece} - mark {at, color?, label?}: paint or label a cell (hits, misses, letters) - draw {from?: "deck", to?: "hand", count?} - play {card, to?: "table", from?}: a card you can see, by id or label - give {card, to: seat} - shuffle {pile?}, collect {into?: "deck", from?: [piles]}: gather and reshuffle - roll {dice?: "2d6"}, pick {options: [...]}: server randomness, logged - score {counter?, seat?, add? | set?} - secret {name, value}: lock in hidden info (the word, the culprit, your fleet); reveal {name} - say {text}, end_turn {next?}, end_game {winner?, reason}, concede Cells are column letter + row number from the top: A1 is the top left.
