ClaudeCraft is a full Minecraft-style survival game, implemented by Claude from frozen specs.

That is about 46,000 lines of JavaScript across 146 files: 11 biomes, redstone, bosses, A* mob AI and a multiplayer relay, with every texture and sound generated procedurally. Eighteen independent auditors then reviewed it. They logged 195 defects, all six criticals were fixed, and 34 acceptance suites check the result.
