AutoGineer summary
Written by AutoGineer from the skill’s own files, not by the author
This skill provides a structured set of guidelines for React Native and Expo development. It covers a range of topics including list management, animation implementation, navigation, UI patterns, state management, and monorepo configuration. The rules are organized by priority to help developers maintain consistent coding standards and architectural patterns across their mobile projects.
What it does
- Provides rules for optimizing list and scroll behavior
- Offers guidance on implementing animations with Reanimated
- Defines patterns for UI components and native module usage
- Suggests state management and rendering practices
- Outlines configuration standards for monorepo projects
When to use it
- When building or maintaining React Native and Expo applications
- When implementing complex animations or list views
- When structuring projects with native dependencies
- When seeking standardized approaches to common mobile UI patterns
Advantages
- Categorized rules based on development priority
- Covers both core React Native and Expo-specific patterns
- Includes guidance for modern React compiler compatibility
- Provides clear prefixes for rule identification
Usage examples
- “How should I handle large lists in my React Native app?”
- The agent will provide guidelines on using FlashList, memoizing items, and stabilizing callback references to manage list rendering.
- “What are the best practices for animations in Expo?”
- The agent will suggest animating only transform and opacity properties and using specific gesture detectors for better interaction handling.

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 Apply
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

list-performance-virtualize- Use FlashList for large listslist-performance-item-memo- Memoize list item componentslist-performance-callbacks- Stabilize callback referenceslist-performance-inline-objects- Avoid inline style objectslist-performance-function-references- Extract functions outside renderlist-performance-images- Optimize images in listslist-performance-item-expensive- Move expensive work outside itemslist-performance-item-types- Use item types for heterogeneous lists
2. Animation (HIGH)
animation-gpu-properties- Animate only transform and opacityanimation-derived-value- Use useDerivedValue for computed animationsanimation-gesture-detector-press- Use Gesture.Tap instead of Pressable
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 imagesui-image-gallery- Use Galeria for image lightboxesui-pressable- Use Pressable over TouchableOpacityui-safe-area-scroll- Handle safe areas in ScrollViewsui-scrollview-content-inset- Use contentInset for headersui-menus- Use native context menusui-native-modals- Use native modals when possibleui-measure-views- Use onLayout, not measure()ui-styling- Use StyleSheet.create or Nativewind
5. State Management (MEDIUM)
react-state-minimize- Minimize state subscriptionsreact-state-dispatcher- Use dispatcher pattern for callbacksreact-state-fallback- Show fallback on first renderreact-compiler-destructure-functions- Destructure for React Compilerreact-compiler-reanimated-shared-values- Handle shared values with compiler
6. Rendering (MEDIUM)
rendering-text-in-text-component- Wrap text in Text componentsrendering-no-falsy-and- Avoid falsy && for conditional rendering
7. Monorepo (MEDIUM)
monorepo-native-deps-in-app- Keep native dependencies in app packagemonorepo-single-dependency-versions- Use single versions across packages
8. Configuration (LOW)
fonts-config-plugin- Use config plugins for custom fontsimports-design-system-folder- Organize design system importsjs-hoist-intl- Hoist Intl object creation

title: Minimize State Variables and Derive Values impact: MEDIUM impactDescription: fewer re-renders, less state drift tags: state, derived-state, hooks, optimization
Minimize State Variables and Derive Values
Use the fewest state variables possible. If a value can be computed from existing state or props, derive it during render instead of storing it in state. Redundant state causes unnecessary re-renders and can drift out of sync.
Incorrect (redundant state):
function Cart({ items }: { items: Item[] }) {
const [total, setTotal] = useState(0)
const [itemCount, setItemCount] = useState(0)
useEffect(() => {
setTotal(items.reduce((sum, item) => sum + item.price, 0))
setItemCount(items.length)
}, [items])
return (
<View>
<Text>{itemCount} items</Text>
<Text>Total: ${total}</Text>
</View>
)
}Correct (derived values):
function Cart({ items }: { items: Item[] }) {
const total = items.reduce((sum, item) => sum + item.price, 0)
const itemCount = items.length
return (
<View>
<Text>{itemCount} items</Text>
<Text>Total: ${total}</Text>
</View>
)
}Another example:
// Incorrect: storing both firstName, lastName, AND fullName
const [firstName, setFirstName] = useState('')
const [lastName, setLastName] = useState('')
const [fullName, setFullName] = useState('')
// Correct: derive fullName
const [firstName, setFirstName] = useState('')
const [lastName, setLastName] = useState('')
const fullName = `${firstName} ${lastName}`State should be the minimal source of truth. Everything else is derived.
