Rules your agent knows

By Mirko Kiefer. An unofficial experiment, not affiliated with ARC Prize. Puzzles: ARC-AGI-1 by François Chollet, Apache-2.0. The agent is claude-opus-5-5, on your key. Rules it writes run in a sandboxed worker with no network, and never see your key. This page has no analytics. The mic uses your browser's speech service, which may send audio to Google or Apple.
