Play LLM Reversi

The human plays on the browser board. Use the installed reversi command for the LLM's moves. For CLI-vs-CLI, run Black and White in independent assistant sessions. Treat each returned snapshot as the current game state.

Start or resume

1. Read reversi --help for the available commands, then run reversi status.
2. If the command is unavailable, tell the user that LLM Reversi needs installation. If the local server is unavailable, start reversi start in a persistent process and issue play commands from another shell.
3. When the status is setup, ask the human to choose the mode, color, and optional names in the browser. The CLI has no game-creation command.
4. In CLI-vs-CLI mode, choose one color for this session and put --color black or --color white immediately after reversi on every participant command. Each color runs in its own session.

Play turns

• Read status, including turn, legal_moves, takeback, event, and revision. Coordinates run from A1 at the upper-left to H8 at the lower-right. Black moves first.
• If the status is finished or resigned, report the result and stop the game loop. If an event is game_reset, read status again and continue with the new game.
• When it is this session's turn, choose a move from legal_moves and submit reversi move MOVE. The command waits for the next action by default; use --no-wait when an immediate return is needed.
• When it is the human's or other session's turn, use reversi wait. Use reversi wait --after-revision N when waiting for a change after a reviewed snapshot's revision. Keep at most one pending wait in each session.
• The server automatically skips a color with no legal move; do not submit a pass. The same color may make consecutive actual moves after an automatic skip. When neither color can move, the disc counts decide the winner or a draw.
• If the opponent requests a takeback, decide whether to approve it from the user's instructions and game context, then use reversi takeback accept or reversi takeback reject. Do not submit a move while a request is pending.
• To request a takeback of this session's last actual move, use reversi takeback request and process the response. Acceptance restores that move's before-state, including flips and automatic passes; do not assume a fixed number of plies is undone.
• Use reversi resign when this participant resigns. The human controls their moves and browser choices.

Two independent CLI sessions

• Put the session's color before every participant command, including status, wait, move, takeback, and resign: for example, reversi --color black move D3.
• The opposite-color session responds to a takeback request with reversi --color COLOR takeback accept or reversi --color COLOR takeback reject.
• After a game_reset event, run reversi --color COLOR status before deciding the next action.
• color_required and player_not_cli indicate a mismatch between the command, game mode, or controlled color. Correct the invocation using the latest status.
• Keep the server process running through the game. Each CLI session controls only its selected color.
