Azure Cosmos DB performance optimization and best practices guidelines for NoSQL, partitioning, queries, and SDK usage. Use when writing, reviewing, or refactoring code that interacts with Azure Cosmos DB, designing data models, optimizing queries, or implementing high-performance database operations.
React Three Fiber post-processing - @react-three/postprocessing, bloom, DOF, screen effects. Use when adding visual effects, color grading, blur, glow, or creating custom screen-space shaders.
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).
