# React Native Performance Analyzer **Scope:** React Native apps only (a `package.json` with `react-native`, optionally Expo — CLI or Expo). Covers JS/TS app code plus `android/` / `ios/` native projects where they affect performance. This is an **analyze-and-fix** skill, not a rewrite tool. ## When To Use Use when an RN app has: slow startup, laggy scrolling, FlatList/SectionList issues, unnecessary re-renders, slow navigation, heavy screens, memory leaks, large bundle size, poor Android/iOS release performance, native-module bottlenecks, or performance complaints from users/clients/QA/monitoring. The goal is **not** to blindly optimize. It is to identify the **real bottleneck**, apply **safe fixes**, and **validate the result properly**. ## Universal Compatibility ### Supported AI Tools (2026) **Terminal / CLI agents** - Claude Code (Anthropic) - OpenCode (open source, most-starred CLI agent) - OpenAI Codex CLI - OpenHands (formerly OpenDevin) - Cline (IDE extension + CLI + SDK) - Aider (git-native) - Pi (lean token-efficient harness) - Goose (Block → Linux Foundation) - Continue (`cn` CLI) - Qwen Code - Gemini CLI (retired June 2026) → Antigravity CLI (Google, closed-source successor) - Kimi Code CLI - Crush, Kilo Code, Forge, ZeroStack, OpenAgent, OpenClaude (newer open-source harnesses) **IDE-embedded agents** - Cursor (agentic IDE, acquired Continue.dev) - Devin Desktop (formerly Windsurf) - GitHub Copilot (VS Code / JetBrains / Xcode Agent Mode) - Zed AI - JetB
