How to use it

Models / tools: Claude Fable 5.1

1. Swap in the genre, interface language and asset tools you have, then give it to an AI coding agent that can read and write files and call tools.

What it can do

This is a game-building prompt shared by GitHub user Nipale-ai, meant to be run by an AI coding agent. It asks for a playable 3D game in a single standalone HTML file and lets the model pick the genre and theme. It also tells the agent to use Blender on the author's machine for models and ComfyUI for textures, short video and music, to check each asset before accepting it and redo the ones that don't fit, and finally to confirm the page runs in the browser. The author says he ran it with Claude Fable 5.1 and got NEON WARDEN, a sci-fi arena game. What sets it apart is that it sets the goal and the acceptance checks without dictating the gameplay, so the agent decides what to build and checks its own quality. Swap in the genre, interface language and asset tools you have, then give it to an AI coding agent that can read and write files and call tools.

Who it is for

Developers and game fans who want to see an AI coding agent build a whole game on its own.

Before you use it

The author used Claude Fable 5.1 with Blender and ComfyUI on his own machine; if you don't have those tools, substitute ones you do. The original includes paths and a server name from the author's computer, so change them before reuse. The agent creates files and calls tools on your machine, and your code and assets go to whichever model service you choose. Model and asset generation costs are separate, and the time and cost the author recorded come from a single run of his own. The author has not stated a reuse licence, so we show only an excerpt; see the author's repository for the full prompt.

Follow the stated license. Do not use the output to replicate someone else’s work or a real person’s likeness.
