I built a racing game using Fable 5. Here is how it works and what I learned.

To get the best results, use the /goal command in Claude Code.

Follow these steps:

In my test, Fable 5 ran for 30 minutes straight to complete the task. I ran a few more cycles to refine the design.

The goal verification is impressive. The tool creates a separate directory to write test code and take screenshots. It uses these to verify and improve the game.

When I restricted its access to certain folders, it built a full testing framework in Python to finish the job. I plan to add my Playwright skills to its configuration next time to make this process faster.

Fable 5 feels better than Opus 4.8 for complex tasks. However, for smaller tasks like adding intro scenes, Opus 4.8 works well enough.

My main takeaway: The Agent Harness matters more than the model for 90% of your work.

I built this retro racer using:

The game runs entirely in your browser. I spent several hours fine-tuning the design with Claude Design.
