Claude Code is Anthropic’s code interface for the Claude family of models. A member of the Claude Code team has published an SDK that wires Claude Code into the ARC-AGI-3 API so you can drive games directly from the terminal. Repository: https://github.com/ThariqS/ARC-AGI-3-ClaudeCode-SDK Key features:
  • Minimal JavaScript/Node CLI wrappers (no Python required).
  • Helper scripts for listing games, opening / closing score-cards, and submitting actions.
  • Turn-based “auto-solver” (play-arc-with-claude.js) that lets Claude iteratively reason about the grid, decide on the next action, and track progress.
  • Works with the Claude Code CLI (install via npm i -g @anthropic-ai/claude) so you can hop into an interactive session at any point.
Quick start: 
# Clone and install
git clone https://github.com/ThariqS/ARC-AGI-3-ClaudeCode-SDK.git
cd ARC-AGI-3-ClaudeCode-SDK && npm install

# Initialise with your API key
node init.js --api-key YOUR_ARC_API_KEY

# Let Claude solve the default game for up to 50 turns
node play-arc-with-claude.js

# …or target a specific game (example: ls20)
node play-arc-with-claude.js ls20-016295f7601e 100
The SDK ships with convenience scripts in the actions/ folder (list-games.js, start-game.js, action.js, etc.) if you prefer a more manual driving style. Because this template lives in its own repository, you don’t invoke it via uv run main.py; instead run the Node scripts shown above (or adapt them to your workflow).
