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:
- State your goal clearly.
- Provide your preferred tech stack.
- Ask the AI to interview you about design decisions.
- Let the tool build the product.
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:
- Three.js
- HTML5, CSS, and JS
- Open-source GLB car models
The game runs entirely in your browser. I spent several hours fine-tuning the design with Claude Design.
