What it does

The fable5-world-demo allows founders to explore and interact with 3D worlds built with three.js, testing AI capabilities in a virtual environment.

When to use it

•When you need to test AI agents in a 3D virtual environment
•When you want to explore the capabilities of Claude Fable 5's AI in a visual setting
•When you are looking for a demo to understand how AI can interact with 3D worlds

Ready-to-paste prompt

Open `index.html` in a browser and use the mouse to navigate the 3D world, observing how the AI agent interacts with the environment

Heads up: Make sure you have a compatible version of Node.js installed, as the demo uses TypeScript and three.js, which may have specific version requirements
