Usage Examples

Once installed, the agent uses skills automatically based on context:

Review my entire Three.js app and give me a score from 1 to 100.
Explain what's good, what needs improvement, and provide actionable fixes.

Help me set up a Three.js scene with proper memory management

Review my R3F component for performance issues

How do I load GLTF models with Drei?

Optimize my shader for mobile devices

Set up WebXR for my VR experience

Implement GPU particles with compute shaders

Integrate Rapier physics with my Three.js scene
