MazeBench is a local browser app for building and playing persistent 3D puzzle worlds, then evaluating models against the same JavaScript engine.
Python 3.9+ and Node.js are required.
pip install mazebench
mazebench launchThis opens the Play, Build, and Agent modes. Run mazebench --help for other
commands.
Play directly in an ASCII terminal with arrow-key controls:
mazebench ascii
mazebench ascii --level CxDBoth CxD and the full level_CxD level ID are accepted.
Play interactively with the same controls while showing the structured JSON observation a model receives, with literal object names and every room object included:
mazebench json --level CxD --omniscientOmit --omniscient to include only objects visible in the equivalent ASCII
view. Names are not hidden unless --hide-names is passed explicitly. JSON
arrays are kept on one line in the terminal. Pipe the output or pass --once
to print a single snapshot instead of starting an interactive session.
Agent runs require Prime Sandbox access. Verifiers runs its stock harness in
one sandbox and gives it four tools from the authoritative game server in a
second sandbox. Replay video requires a Chromium-family browser and ffmpeg.
