presenting-metal-drawables

presenting-metal-drawables is a Graphics, 3D & shaders skill for AI agents, published by apple in the game-porting-toolkit repository on GitHub. Skillspace rates presenting-metal-drawables C (74/100) and it passed the safety scan; the rating is based on static analysis only.

ALWAYS use when implementing or debugging the Metal drawable presentation contract — `CAMetalLayer` configuration, drawable lifecycle (`nextDrawable`, `waitForDrawable`, `signalDrawable`, `present`), vsync (`displaySyncEnabled`), `CAMetalDisplayLink`, HDR/EDR layer setup, direct-to-display vs composited, or drawable-residency-set rules. Trigger for CAMetalLayer, CAMetalDrawable, nextDrawable, signalDrawable, waitForDrawable, displaySyncEnabled, presentAfterMinimumDuration, drawableSize, framebufferOnly, wantsExtendedDynamicRangeContent, EDR headroom, ProMotion, swap chain port, "blank window", "vsync not working". Do NOT trigger for render-thread / run-loop / resize / fullscreen integration on macOS — use `setting-up-macos-window`. General `MTLResidencySet` semantics — use `managing-metal4-resources`. Cross-API translation tables for non-presentation APIs — use `translating-to-metal4-api`. For dual-frame presentation via a present thread — use `using-metalfx-frame-interpolation`.
