@llmletsplay/versus-go

Drop-in Go engine with captures, ko tracking, passing, and scoring.

Install

npm install @llmletsplay/versus-go

Quick Start

import { GoGame } from '@llmletsplay/versus-go';

const game = new GoGame('demo');
await game.initializeGame();
const state = await game.getGameState();

console.log(state.currentPlayer);

Host App Pattern

The engine is meant to live inside your app runtime, whether that runtime is a browser, server action, or agent worker.

const userMove = {
  player: 'black',
  action: 'place',
  row: 3,
  col: 3,
};

await game.validateMove(userMove);
const afterUserMove = await game.makeMove(userMove);

const agentMove = await askAgent(afterUserMove);
await game.validateMove(agentMove);
const afterAgentMove = await game.makeMove(agentMove);

For copy-pasteable host examples, see examples/agent-turn-loop.mjs and examples/react-agent-omok.tsx.
