    "body_text": "The experiment put four agents in a randomly generated Minecraft world with only the standard open-source Mineflayer library and one goal: defeat the Ender Dragon. The agents assigned their own work, wrote and debugged 2,783 programs, shared discoveries and recovered one another's items through in-game chat and memory. They finished after 27 hours and 14 minutes and 605 deaths without researcher intervention, according to the authors. The run is a single sandboxed game result and the claim of first end-to-end autonomous completion is the authors' assessment. Its value is as a trace of long-horizon coordination under repeated failure, not proof that game success transfers directly to enterprise work.",
