Grue Lab
Built at The Harness Engineering & Model Wrangling Hackathon · Sep 26, 2026 · New York, NY
Zorkinator plays Zork I with a harness that turns every death into a lesson instead of forgetting it. It builds its own map and memory as it plays, and a rule only earns the right to block a risky move after it's proven, by mechanically replaying every past game, that it actually would have prevented a death. Everything it learns is stored and versioned in MongoDB Atlas, so you can watch the same model go from clueless to competent, one game at a time.
