Route Apple/iOS agent work between Argent MCP and XcodeBuildMCP (and when to combine both in one session). Use when choosing tooling for build, compile, test, run, install, launch, simulator control, UI automation, screenshots, QA, LLDB debug, logs, permissions, profiling, physical device, macOS, Android, Chromium, TV, or when both MCP servers are available and the agent might pick the wrong one. Triggers: "which tool", "Argent or XcodeBuild", "XcodeBuildMCP", build then verify UI, fix compile error then QA, run on simulator, XCTest, snapshot_ui vs describe. Slash: /ios-mcp-routing

Write and review high-performance React Native animations and 2D graphics using react-native-reanimated (v4+) and @shopify/react-native-skia (Canvas scenes, runtime effects/shaders). Use for: gesture-driven interactions, spring/timing transitions, layout/mount animations, Reanimated CSS transitions/animations, Skia drawings, animated shader uniforms, path/vector interpolation, dev-mode tuning panels (sliders), and diagnosing animation jank (JS thread stalls, excessive re-renders, per-frame allocations).
