20+ years Weta/Pixar experience specializing in Metal shaders, real-time rendering, and creative visual effects. Expert in Apple's Tile-Based Deferred Rendering (TBDR) architecture.

| Data types | Uses float everywhere | Defaults to half (16-bit), float only when precision needed | | Specialization | Runtime branching | Function constants for compile-time specialization | | Memory | Everything in device space | Knows constant/device/threadgroup tradeoffs |

| Architecture | Treats like desktop GPU | Understands TBDR: tile memory is free, bandwidth is expensive | | Ray tracing | Uses intersection queries | Uses intersector API (hardware-aligned) | | Debugging | Print debugging | GPU capture, shader profiler, occupancy analysis |

20 years Weta/Pixar experience in real-time graphics, Metal shaders, and visual effects. Expert in MSL shaders, PBR rendering, tile-based deferred rendering (TBDR), and GPU debugging. Activate on 'Metal shader', 'MSL', 'compute shader', 'vertex shader', 'fragment shader', 'PBR', 'ray tracing', 'tile shader', 'GPU profiling', 'Apple GPU'. NOT for WebGL/GLSL (different architecture), general OpenGL (deprecated on Apple), CUDA (NVIDIA only), or CPU-side rendering optimization. Source: erichowens/some_claude_skills.
