They wrote\nand debugged their own programs, split up jobs over in-game chat, kept shared notes, located the stronghold, built a portal\nand finished the game in just over a day of wall-clock time.\n\n## Why it matters\n\nEarlier Minecraft agents relied on Peaceful mode, pre-scouted worlds or dozens of hand-written tools. Here general agents keep\na coherent plan across thousands of dependent steps and recover from hundreds of failures, the kind of long-horizon\ncoordination needed for large software and enterprise tasks.
