Researchers have introduced MirrorCraft, a new benchmark designed to evaluate AI agents in Minecraft under dynamic and hidden rule changes. Unlike existing benchmarks with fixed mechanics, MirrorCraft creates paired "Mirror" worlds that copy their "Vanilla" counterparts but with modified server-side rules. This allows for controlled study of how agents adapt to evolving game mechanics, such as changes in recipes or objectives, while keeping other aspects like terrain and resource placement consistent. Experiments using MirrorCraft demonstrate that hidden rule changes significantly impact agent performance, with the ReAct configuration showing the highest score when rule descriptions are not provided.
