Technical Overview & Architectural Context

Autonomous coding agents frequently generate brittle mobile architectures because they treat React Native like standard web React. Without deterministic domain rules, models like Claude Code, Cursor, and Codex hallucinate obsolete APIs, use DOM elements (<div/>, <span/>), fail to configure native Safe Area contexts, omit essential react-native-reanimated Babel plugins, and misconfigure Expo Router v3 layout hierarchies. This leads to broken Metro bundler sessions, white-screen startup crashes on iOS/Android, and cascading layout clipping. The 'cursor-react-native' skill establishes strict architectural guardrails. It enforces standard React Native primitives (View, Text, Pressable), requires react-native-safe-area-context wrappers for responsive notches and home indicators, ensures native gesture responder chains operate on the UI thread, and configures NativeWind v4 Tailwind setups deterministically. By forcing the agent to inspect the existing project structure and validate dependencies prior to editing code, this skill prevents recurring runtime exceptions and context window degradation.

Prerequisites & Environment Requirements

Codex Desktop, Claude Code CLI, Cursor, or Windsurf installed with active workspace permissions
Node.js 20+ and pnpm / npm / bun installed in the local runtime sandbox
Expo CLI (npx expo) and CocoaPods (for macOS iOS local simulator verification)

Step-by-Step Execution Playbook

Local Environment Setup & SKILL.md Mounting

Create the local skill manifest directory and inject verified procedural rules into your workspace.

Autonomous runtimes parse agent rules from project-level or global configuration paths. For project-scoped execution in Cursor and Windsurf, mount the SKILL.md into `.cursor/rules/` or `.agents/skills/cursor-react-native/SKILL.md`. Claude Code and Codex load procedural manifests from the root or dedicated `.agents/skills` tree. This forces the agent to read operational boundaries before drafting or modifying mobile UI components.

Terminal Command

# Rules
1. Always wrap screen containers with SafeAreaView or useSafeAreaInsets.
2. Ensure animations leverage react-native-reanimated and run on the UI thread.
3. Verify Expo Router file-based route syntax under app/ directory.
4. Check packages before installing to avoid incompatible native binary modules.
Production Pro-Tip

Keep the SKILL.md rules succinct. Agents prioritize rules near the top of the context window. Avoid embedding multi-page styling guides that deplete token cache.

Sandbox Gotcha

In Cursor, ensure the `.cursor/rules/` file contains `globs: **/*.tsx, **/*.ts` so the skill is only injected during mobile codebase editing, preventing context pollution during backend edits.

2

Environment Secrets & Dependency Validation

Inject required environment variables safely and assert Expo native module compatibility.

Mobile builds fail when native package versions drift from the Expo SDK baseline. The agent must verify that Expo, React Native, and NativeWind share compatible semantic versions. Use `npx expo install --check` inside the workspace to align all native dependencies with the installed Expo SDK.

Terminal Command
npx expo install expo react-native nativewind react-native-reanimated react-native-safe-area-context && npx expo install --check
babel.config.js
module.exports = function (api) {
  api.cache(true);
  return {
    presets: [
      ['babel-preset-expo', { jsxImportSource: 'nativewind' }],
      'nativewind/babel',
    ],
    plugins: [
      'react-native-reanimated/plugin',
    ],
  };
};
Production Pro-Tip

Always use 'npx expo install' instead of standard 'npm install' or 'pnpm add' to allow Expo's package matrix to resolve matching native framework binaries automatically.

Sandbox Gotcha

Placing 'react-native-reanimated/plugin' anywhere other than the absolute last element in the Babel plugins array triggers undefined worklet errors at runtime.

3

Intent Matching & Trigger Invocation

Verify deterministic activation using tested natural language prompts and route structures.

Trigger the agent with explicit Expo Router v3 intents. The skill instructs the agent to create typed route files within the `app/` hierarchy and bind responsive safe area containers rather than hardcoded status bar paddings.

Terminal Command
claude "Use cursor-react-native to generate an authenticated modal sheet route under app/(modals)/profile.tsx with smooth Reanimated slide-in and NativeWind styles."
app/(modals)/profile.tsx
import React from 'react';
import { View, Text, Pressable } from 'react-native';
import { useRouter } from 'expo-router';
import { useSafeAreaInsets } from 'react-native-safe-area-context';
import Animated, { FadeInDown } from 'react-native-reanimated';

export default function ProfileModal() {
  const insets = useSafeAreaInsets();
  const router = useRouter();

  return (
    <View 
      className="flex-1 bg-neutral-900 px-6"
      style={{ paddingTop: insets.top, paddingBottom: insets.bottom }}
    >
      <Animated.View entering={FadeInDown.duration(300)} className="mt-8">
        <Text className="text-2xl font-bold text-white">Profile Settings</Text>
        <Text className="text-neutral-400 mt-2">Manage mobile preferences and sync.</Text>
        <Pressable 
          onPress={() => router.back()}
          className="mt-6 bg-blue-600 active:bg-blue-700 py-3 rounded-xl items-center"
        >
          <Text className="text-white font-semibold">Done</Text>
        </Pressable>
      </Animated.View>
    </View>
  );
}
Production Pro-Tip

Explicitly reference screen targets (e.g., 'app/(tabs)/index.tsx' or 'app/(modals)/profile.tsx') in prompts to guide the agent directly to the Expo Router file convention.

Sandbox Gotcha

Do not let the agent write `import { SafeAreaView } from 'react-native'`. Instruct it to always use `react-native-safe-area-context` to prevent notch overlap issues on modern dynamic islands.

4

Verification, Linting & Output Quality Gate

Execute automated self-healing checks and TypeScript verification before accepting agent code.

Require the agent to invoke TypeScript and Expo diagnostics to confirm that no uncompiled JSX or non-native HTML elements exist in the workspace before completing the session.

Terminal Command
npx tsc --noEmit && npx expo-doctor
package.json
{
  "scripts": {
    "verify": "tsc --noEmit && expo-doctor",
    "lint": "eslint . --ext .js,.jsx,.ts,.tsx"
  }
}
Production Pro-Tip

Instruct the agent to run `npx expo-doctor` during its self-correction step. It flags incompatible native pods and misaligned SDK packages before physical device testing.

Sandbox Gotcha

Ensure simulator builds are not running during large file regenerations to avoid Metro bundler lock file collisions (`.metro/cache`).

Real-World Scenario: Scaffolding an Offline-Ready Feed Screen with NativeWind & Reanimated

Tested Trigger Prompt (Feed directly into Codex, Claude, or Cursor):

“Using the cursor-react-native skill, implement an animated product feed screen at app/(tabs)/feed.tsx. It must consume a typed list, provide pull-to-refresh, calculate dynamic Safe Area insets, style items using NativeWind utility classes, and animate item layout mounting with Reanimated.”

Deterministic Agent Verification Pipeline:
Agent inspects existing app/_layout.tsx to verify SafeAreaProvider and NativeWind configuration.
Agent creates app/(tabs)/feed.tsx with FlashList or FlatList, typed interfaces, and RefreshControl.
Agent injects useSafeAreaInsets hook to dynamically account for device bottom tab bar and top notch.
Agent adds Animated.View entering={FadeIn.delay(index * 50)} to list rows for smooth 60fps native performance.
Agent executes 'npx tsc --noEmit' in workspace to guarantee strict TypeScript compliance.

Runtime Troubleshooting & Failure Modes

Error: Invariant Violation: `new NativeEventEmitter()` requires a non-null argument, or Reanimated Worklet generation failed: [Reanimated] Native part of Reanimated doesn't seem to be initialized.

Root Cause: The agent introduced Reanimated hooks without ensuring 'react-native-reanimated/plugin' was listed as the last plugin in babel.config.js, or Metro cache was not cleared after package installation.

Resolution Command / Fix:
npx expo start -c && node -e "console.log('Ensure babel.config.js has react-native-reanimated/plugin as the final entry in plugins array')"
Error: Error: Style property 'pointerEvents' / DOM styling invalid in StyleSheet or NativeWind class parsing error on <div />

Root Cause: Agent hallucinated HTML DOM primitives (div, span) instead of native React Native primitives (View, Text) and attempted to use web-only CSS properties.

Resolution Command / Fix:
sed -i '' 's/<div/<View/g' app/**/*.tsx && sed -i '' 's/<\/div>/<\/View>/g' app/**/*.tsx

Frequently Asked Questions (Expo & React Native Mobile Artisan SOP)

Q:Can I use Expo & React Native Mobile Artisan across Codex, Claude Code, and Cursor simultaneously?

Yes. The skill conforms to the universal SKILL.md specification. You can symlink or copy `.agents/skills/cursor-react-native/SKILL.md` into `.cursor/rules/` or Claude Code workspace profiles without modifying the core procedural directives.

Q:How does Expo & React Native Mobile Artisan prevent context window overflow during long agent sessions?

The skill provides precise architectural guardrails rather than embedding massive template codebases into context. It directs agents to leverage official Expo CLI commands and verifies code using local commands (e.g., tsc, expo-doctor) rather than relying on endless prompt generation loops.

Q:Does this skill require escalated root or container permissions?

No. The skill operates entirely within the workspace sandbox with an audited security score of 98/100. It requires standard file read/write permissions and access to workspace Node/Expo commands, avoiding sudo or host-level kernel permissions.
