Use when working with ANY GPU rendering, Metal, OpenGL migration, shaders, 3D content, RealityKit, AR, or display performance. Covers Metal migration, shader conversion, RealityKit ECS, RealityView, variable refresh rate, ProMotion.
Routes iOS graphics tasks to specialized skills for Metal migration, display performance, and RealityKit 3D content.
npx claudepluginhub charleswiltgen/axiomThis skill inherits all available tools. When active, it can use any tool Claude has access to.
You MUST use this skill for ANY GPU rendering, graphics programming, 3D content display, or display performance work.
Use this router when:
Strategy decisions → /skill axiom-metal-migration
API reference & conversion → /skill axiom-metal-migration-ref
Diagnostics → /skill axiom-metal-migration-diag
Frame rate & render loops → /skill axiom-display-performance
For 3D content in non-game SwiftUI apps, AR experiences, and spatial computing, use the RealityKit skills. For game-specific RealityKit patterns, use the ios-games router instead.
Architecture, ECS, and best practices → /skill axiom-realitykit
API reference → /skill axiom-realitykit-ref
Troubleshooting → /skill axiom-realitykit-diag
| Thought | Reality |
|---|---|
| "I'll just translate the shaders line by line" | GLSL→MSL has type, coordinate, and precision differences. metal-migration-ref has conversion tables. |
| "MetalANGLE will handle everything" | Translation layers have significant limitations for production. metal-migration evaluates the trade-offs. |
| "It's just a black screen, probably a simple bug" | Black screen has 6 distinct causes. metal-migration-diag diagnoses in 5 min vs 30+ min. |
| "My app runs at 60fps, that's fine" | ProMotion devices support 120Hz. display-performance configures the correct frame rate. |
| "I'll just use SceneKit for the 3D model" | SceneKit is soft-deprecated. RealityView and Model3D are the modern path. axiom-realitykit covers SwiftUI integration. |
| "I don't need ECS for one 3D model" | Model3D shows one model with zero ECS. RealityView scales to complex scenes. axiom-realitykit shows both paths. |
