Use when working with ANY GPU rendering, Metal, OpenGL migration, shaders, 3D content, RealityKit, AR, USD/USDZ files, or display performance. Covers Metal migration, shader conversion, RealityKit ECS, RealityView, USDKit, ProMotion.
Why this skill is useful
Provides domain-specific knowledge for GPU rendering, shader conversion, and performance optimization that the AI wouldn't reliably generate on its own.

What this skill does
Graphics You MUST use this skill for ANY GPU rendering, graphics programming, 3D content display, or display performance work. When to Use Use this router when: Porting OpenGL/OpenGL ES code to Metal Porting DirectX code to Metal Converting GLSL/HLSL shaders to Metal Shading Language Setting up MTKView or CAMetalLayer Rendering breaks or blurs when the window resizes or moves between screens Debugging GPU rendering issues (black screen, wrong colors, crashes) Evaluating translation layers (MetalANGLE, MoltenVK) Optimizing GPU performance or fixing thermal throttling App stuck at 60fps on ProMotion device Configuring CADisplayLink or render loops Variable refresh rate display issues Displaying 3D content in a non-game SwiftUI app Building AR experiences with RealityKit Using RealityView or Model3D in SwiftUI Spatial computing or visionOS 3D content Reading, editing, or exporting USD/USDZ files in Swift (USDKit) Adding ML to a render pipeline (MetalFX denoising, Metal tensors, neural rendering) Profiling long game sessions (metalperftrace, look-back traces) Routing Logic Metal Migration Strategy decisions → See skills/metal-migration.md Translation layer vs native rewrite decision Project assessment and migration planning Anti-patterns and common mistakes Pressure scenarios for deadline resistance API reference & conversion → See skills/metal-migration-ref.md GLSL → MSL shader conversion tables HLSL → MSL shader conversion tables GL/D3D API → Metal API equivalents MTKView setup, render pipelines, compute shaders Complete WWDC code examples Diagnostics → See skills/metal-migration-diag.md Black screen after porting Shader compilation errors Wrong colors or coordinate systems Performance regressions Time-cost analysis per diagnostic path Rendering Surfaces Under Window Resizing Any rendering surface in a resizable window → See skills/resizable-rendering.md MTKView drawableSizeWillChange (projection + render-target reallocation, live-resize throttling) CAMetalLayer manua …
