ChessWithClaw

A real-time, turn-based chess platform designed to let human players play against external AI agents (like OpenClaw or other LLMs).

Features

External AI Integration: Designed specifically for LLMs and external bots to connect via API (SSE, Long-Polling, Webhooks) or browser automation.
Real-time Synchronization: Powered by Supabase Realtime for instant board updates.
Transparent Thinking: Agents can submit their "reasoning" alongside their moves, which is displayed live to the human player.
Full Chess Rules: Validates all moves, including castling, en passant, and promotions using chess.js.
Live Chat: Built-in chat system for the human and agent to communicate during the game.

How the AI Works (Architecture)

Unlike traditional chess apps that bundle a local engine like Stockfish, ChessWithClaw acts as a host platform. The AI opponent lives externally and connects to the game using one of four methods:

Browser Automation (Puppeteer/Playwright): The agent opens the /Agent?id=<GAME_ID> URL, reads the DOM for the game state, and interacts with the UI to submit moves and reasoning.
Server-Sent Events (SSE): The agent connects to GET /api/stream?id=<GAME_ID> to receive a continuous stream of JSON updates, and submits moves via POST /api/move.
Long-Polling (Recommended for LLMs): The agent polls GET /api/poll?id=<GAME_ID> which waits for human moves/chat before returning, then submits moves via POST /api/move.
Webhooks: The agent registers a URL via POST /api/webhook to be pinged whenever it is their turn.

Setup Instructions

1. Create Supabase Project

Go to Supabase and create a new project.
Go to the SQL Editor and run the contents of supabase-schema.sql to create the games table and set up Row Level Security (RLS).
Go to Database -> Replication and enable replication for the games table to allow real-time subscriptions.

2. Add Environment Variables

Create a .env file in the root of the project (or copy .env.example) and add your Supabase credentials:

VITE_SUPABASE_URL="your_supabase_project_url"
VITE_SUPABASE_ANON_KEY="your_supabase_anon_key"

3. Install and Run

npm install
npm run dev

The app will be available at http://localhost:3000.

4. How to Deploy

Push your code to a GitHub repository.
Import your repository to your hosting provider (e.g., Vercel, Render).
In the Environment Variables section, add VITE_SUPABASE_URL and VITE_SUPABASE_ANON_KEY.
Deploy the application.
