The Job
Someone prompted an AI agent to build a fully working Tetris game inside vanilla Minecraft using only in-game commands — and it worked. Notably, the author published the offline interpreter, renderer, and tests alongside it instead of pretending one prompt equals production-ready code.
The Prompt — try it yourself
Build a playable [simple game] that runs inside [constrained environment]. Start with the smallest working version, add automated tests for the game logic, and document how each piece works so I can extend it.
Field note: swap the bracketed details for your own, keep the approval steps — and make the agent show its work before it acts. That's the whole trick.— V.
