Metal Gpu

Brings Metal GPU programming patterns directly into your Claude workflow, covering everything from MSL shader syntax to compute kernels and render pipelines. You get correct attribute qualifiers, buffer management patterns, and the full command encoder setup for both rendering and compute. Honestly most useful when you're tired of looking up whether it's `[[vertex_id]]` or `[[position]]`, or you need the boilerplate for MetalKit view rendering without digging through docs. Includes Metal 4 API specifics and Apple Silicon optimization notes like triple buffering and storage mode choices. Works across iOS, macOS, and visionOS.

Core Principles

Always start with the device: MTLCreateSystemDefaultDevice() — every Metal workflow begins here
Command pattern: Device → Command Queue → Command Buffer → Command Encoder → Commit
Shaders are MSL (Metal Shading Language): C++14-based, with Metal-specific types and attributes
Resource management matters: Use appropriate storage modes, avoid unnecessary copies
Triple buffering for render loops to keep CPU and GPU in parallel

Quick Reference: Metal Command Pipeline

MTLDevice

       └─ makeCommandBuffer() → MTLCommandBuffer
            ├─ makeRenderCommandEncoder(descriptor:) → MTLRenderCommandEncoder
            ├─ makeComputeCommandEncoder() → MTLComputeCommandEncoder
            └─ makeBlitCommandEncoder() → MTLBlitCommandEncoder
