mobile-performance-react-native SKILL.md skillA
mobile-performance-react-native from agents-inc/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add agents-inc/skills/mobile-performance-react-native@git:20261016.afd0e14Pins git:20261016.afd0e14 in mdr.lock. Pin the fingerprint instead.

React Native performance profiling, optimization, and monitoring - JS/UI thread analysis, re-render prevention, list optimization, image performance, bundle size, startup time, memory leaks, React Compiler, New Architecture benefits.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# React Native Performance Patterns > **Quick Guide:** Profile before optimizing -- use React Native DevTools Profiler (replaces Flipper since 0.76) and platform profilers to find actual bottlenecks. Target 60 FPS (16.67ms per frame). Understand JS thread vs UI thread: animations on the UI thread, business logic on JS. Use React.memo + useCallback for list items, FlashList for large lists, InteractionManager to defer heavy work during transitions. React Compiler (v1.0+) auto-memoizes most components -- verify before adding manual memoization. Always test in release builds; dev mode adds significant overhead. --- <critical_requirements> ## CRITICAL: Before Using This Skill **(You MUST profile BEFORE optimizing -- use React Native DevTools Profiler or platform tools to identify actual bottlenecks, never optimize blindly)** **(You MUST test performance in RELEASE builds -- dev mode adds significant overhead that masks real performance characteristics)** **(You MUST understand the JS thread vs UI thread distinction -- animations belong on the UI thread, heavy computation must be deferred with InteractionManager)** …

How to install
mdr add agents-inc/skills/mobile-performance-react-native@sha256:f164eccf7dd2c5cbThe line at the top of this page pins the label git:20261016.afd0e14, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
