Hey HN - I built an agent harness for NetHack that exposes a Python sandbox for agents to write game commands and script their way to ascension. More recently I built a web app around this framework that allows anyone to watch the agents play live - you can even sign in with OpenRouter and run your own playthroughs! More information about the agent harness here:
