SOC 직업 분류 기준
Use when fixing or auditing ANY accessibility issue — VoiceOver, Dynamic Type, color contrast, touch targets, WCAG compliance, App Store accessibility review.
Use when implementing, testing, or evaluating ANY Apple Intelligence, on-device AI, or speech-to-text feature. Covers Foundation Models, @Generable, LanguageModelSession, Tool protocol, eval suites, model-as-judge scoring, SpeechTranscriber, CoreML.
Use when the user wants to triage a CORPUS of production crashes/hangs from an aggregator (Sentry, App Store Connect) — grouped, counted issues — rather than a single crash file.
Use when the user mentions file storage issues, data loss, backup bloat, or asks to audit storage usage.
Use when the user wants to audit test quality, find flaky test patterns, speed up test execution, or prepare for Swift Testing migration.
Use when ANY iOS build fails, test crashes, Xcode misbehaves, or environment issue occurs before debugging code. Covers build failures, compilation errors, dependency conflicts, simulator problems, environment-first diagnostics.

You MUST use this skill for ANY GPU rendering, graphics programming, 3D content display, or display performance work.
Use this router when:
Strategy decisions → See skills/metal-migration.md
API reference & conversion → See skills/metal-migration-ref.md
Diagnostics → See skills/metal-migration-diag.md
Frame rate & render loops → See skills/display-performance.md
For 3D content in non-game SwiftUI apps, AR experiences, and spatial computing, use the RealityKit skills. For game-specific RealityKit patterns, use the axiom-games router instead.

| Thought | Reality |
|---|---|
| "I'll just translate the shaders line by line" | GLSL→MSL has type, coordinate, and precision differences. metal-migration-ref has conversion tables. |
| "MetalANGLE will handle everything" | Translation layers have significant limitations for production. metal-migration evaluates the trade-offs. |
| "It's just a black screen, probably a simple bug" | Black screen has 6 distinct causes. metal-migration-diag diagnoses in 5 min vs 30+ min. |
| "My app runs at 60fps, that's fine" | ProMotion devices support 120Hz. display-performance configures the correct frame rate. |
| "I'll just use SceneKit for the 3D model" | SceneKit is soft-deprecated. RealityView and Model3D are the modern path. skills/realitykit.md covers SwiftUI integration. |
| "I don't need ECS for one 3D model" | Model3D shows one model with zero ECS. RealityView scales to complex scenes. skills/realitykit.md shows both paths. |
| "I'll parse the USD file myself / bundle OpenUSD" | USDKit is system-provided USD on the 27 releases. skills/usdkit.md covers stages, editing, and compressed export. |
| "I'll write my own pathfinding over the scene graph" | RealityKit 27 ships navigation meshes with costs and off-mesh connections. skills/realitykit-ref.md Part 10. |
| "The frame drop only happens after an hour of play, can't trace that" | The 27 releases record Metal metrics continuously — collect after the fact with metalperftrace. skills/display-performance.md Part 12. |
