React Native Skills

Comprehensive best practices for React Native and Expo applications. Contains

rules across multiple categories covering performance, animations, UI patterns,

and platform-specific optimizations.

When to Use

Reference these guidelines when:

• Building React Native or Expo apps
• Optimizing list and scroll performance
• Implementing animations with Reanimated
• Working with images and media
• Configuring native modules or fonts
• Structuring monorepo projects with native dependencies

Rule Categories by Priority

| Priority | Category | Impact | Prefix |

| -------- | ---------------- | -------- | -------------------- |

| 1 | List Performance | CRITICAL | list-performance- |

| 2 | Animation | HIGH | animation- |

| 3 | Navigation | HIGH | navigation- |

| 4 | UI Patterns | HIGH | ui- |

| 5 | State Management | MEDIUM | react-state- |

| 6 | Rendering | MEDIUM | rendering- |

| 7 | Monorepo | MEDIUM | monorepo- |

| 8 | Configuration | LOW | fonts-, imports- |

Quick Reference

1. List Performance (CRITICAL)

• list-performance-virtualize - Use FlashList for large lists
• list-performance-item-memo - Memoize list item components
• list-performance-callbacks - Stabilize callback references
• list-performance-inline-objects - Avoid inline style objects
• list-performance-function-references - Extract functions outside render
• list-performance-images - Optimize images in lists
• list-performance-item-expensive - Move expensive work outside items
• list-performance-item-types - Use item types for heterogeneous lists

2. Animation (HIGH)

• animation-gpu-properties - Prefer transform and opacity when layout need not change
• animation-derived-value - Use useDerivedValue for computed animations
• animation-gesture-detector-press - Consider Gesture.Tap for animated press feedback while preserving accessibility

3. Navigation (HIGH)

• navigation-native-navigators - Use native stack and native tabs over JS navigators

4. UI Patterns (HIGH)

• ui-expo-image - Use expo-image for all images
• ui-image-gallery - Use Galeria for image lightboxes
• ui-pressable - Use Pressable over TouchableOpacity
• ui-safe-area-scroll - Handle safe areas in ScrollViews
• ui-scrollview-content-inset - Use contentInset for headers
• ui-menus - Use native context menus
• ui-native-modals - Use native modals when possible
• ui-measure-views - Use onLayout, not measure()
• ui-styling - Use StyleSheet.create or Nativewind

5. State Management (MEDIUM)

• react-state-minimize - Minimize state subscriptions
• react-state-dispatcher - Use dispatcher pattern for callbacks
• react-state-fallback - Show fallback on first render
• react-compiler-destructure-functions - Destructure for React Compiler
• react-compiler-reanimated-shared-values - Handle shared values with compiler

6. Rendering (MEDIUM)

• rendering-text-in-text-component - Wrap text in Text components
• rendering-no-falsy-and - Avoid falsy && for conditional rendering

7. Monorepo (MEDIUM)

• monorepo-native-deps-in-app - Keep native dependencies in app package
• monorepo-single-dependency-versions - Use single versions across packages

8. Configuration (LOW)

• fonts-config-plugin - Use config plugins for custom fonts
• imports-design-system-folder - Organize design system imports
• js-hoist-intl - Hoist Intl object creation

How to Use

Read individual rule files for detailed explanations and code examples:

rules/list-performance-virtualize.md
rules/animation-gpu-properties.md

Each rule file contains:

• Brief explanation of why it matters
• Incorrect code example with explanation
• Correct code example with explanation
• Additional context and references

Full Compiled Document

The catalog bundles the individual rules/ files; the upstream compiled AGENTS.md is not included.

Limitations

• Use this skill only when the task clearly matches the scope described above.
• Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
• Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.

Examples are contextual snippets: supply project imports, types and components. Check installed RN/Expo/Reanimated/list versions before copying APIs; performance labels are qualitative priorities, not measured guarantees. Preserve existing stack choices, accessibility, focus, keyboard and platform behavior. Install compatible native dependencies only within the requested task; prebuild/rebuild can modify native projects.
