If you're doing any GPU rendering, graphics work, or 3D content display on iOS, this routes your requests to the right APIs and patterns. It's part of the broader axiom suite from charleswiltgen, which has picked up decent traction with nearly 1,000 GitHub stars and 196 installs here. The skill positions itself as mandatory for graphics programming, which is a bold claim but makes sense if you want consistent handling of Metal, rendering pipelines, and display performance optimization. It keeps Claude from wandering into deprecated OpenGL territory or suggesting macOS-only approaches when you're targeting iPhone and iPad.
