Rana Hanocka demos Build World: a single prompt lets the Astra agent wire up game logic and construct a playable cozy alien marketplace in Three.js via Thrixel, a 3D creation engine any agent can plug into. She claims Astra is faster and better than Opus/Fable at this task, and every creation publishes to a shareable live link.
