SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps you optimize a React Native app that feels slow by identifying the real runtime bottlenecks through profiling, then applying targeted fixes instead of guesswork.

Core Features & Use Cases

Quick render hot-spot scan: Uses a render counter approach to spot which components are causing the most work.
Deep performance measurement: Runs the dedicated React Native profiler, analyzes results across JS-native profiling reports, and ties findings to concrete issues.
Mechanical + semantic sweeping: Performs deterministic lint sweeps and judgment-based semantic checks (memoization, list rendering, animations, async patterns, effect cleanup), then verifies improvements with regression checks.

Use cases include fixing excessive re-renders, reducing UI jank, improving startup, and tuning animations and list performance—especially when you suspect the app’s performance issues are hard to reproduce or were missed by static analysis.

Quick Start

Ask Argent: "Optimize our React Native app performance—start with a lint sweep, run the React Native profiler on the main user flows, fix the biggest bottleneck, and re-profile to confirm no regressions."

FAQPage Schema

How do I fix React Native UI jank and slow rendering?▼

Find React Native render bottlenecks by running a render counter scan to spot which components cause the most work, followed by deep JS-native profiler measurements tied to concrete source issues.

What is the best way to profile React Native startup performance?▼

Profile React Native startup performance by running the dedicated React profiler across core user flows, analyzing JS-native reports, and executing one-fix-per-cycle validation with regression checks to confirm metric improvement.

Can I use lint sweeps to detect React Native performance issues?▼

Use deterministic lint sweeps alongside semantic checks to detect React Native performance issues like missing memoization, improper effect cleanup, and inefficient async patterns before running runtime profiler measurements.

Why does my React Native app feel slow even after static analysis passes?▼

Your React Native app feels slow after static analysis because runtime bottlenecks like excessive re-renders and degraded startup often require dynamic fiber-tree inspection and profiler measurements to identify and resolve.
