Creator here. I built these over ~2 weeks each as a solo dev.

The key insight: instead of generating code for you to paste, the agent directly manipulates the editor through HTTP polling. This means it can:

- Create/modify/delete objects in the scene - Simulate keyboard and mouse input during play mode - Take screenshots and inspect the scene tree - Work in Editor mode without entering Play

Unity has ~100 tools, Godot 30, Unreal 40+. All Apache 2.0.

The plugins also work with game dev AI personas from https://clawsouls.ai/souls (gamedev-mentor, game-designer, etc.)

Happy to answer questions about the architecture or specific use cases.
