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
1. List Performance (CRITICAL)
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

Recommended Agent Skills
Expand your agent's capabilities with these related and highly-rated skills.
fcakyon/claude-codex-settings
hetzner-deploy
This skill should be used when user asks to "deploy to Hetzner", "create Hetzner server", "manage Hetzner Cloud", "hcloud CLI", or works with Hetzner Cloud infrastructure including servers, networks, firewalls, load balancers, DNS zones, and volumes.
fcakyon/claude-codex-settings
Use this skill whenever the user wants to do anything with PDF files. This includes reading or extracting text/tables from PDFs, combining or merging multiple PDFs into one, splitting PDFs apart, rotating pages, adding watermarks, creating new PDFs, filling PDF forms, encrypting/decrypting PDFs, extracting images, and OCR on scanned PDFs to make them searchable. If the user mentions a .pdf file or asks to produce one, use this skill.
fcakyon/claude-codex-settings
docx
Use this skill whenever the user wants to create, read, edit, or manipulate Word documents (.docx files). Triggers include: any mention of 'Word doc', 'word document', '.docx', or requests to produce professional documents with formatting like tables of contents, headings, page numbers, or letterheads. Also use when extracting or reorganizing content from .docx files, inserting or replacing images in documents, performing find-and-replace in Word files, working with tracked changes or comments, or converting content into a polished Word document. If the user asks for a 'report', 'memo', 'letter', 'template', or similar deliverable as a Word or .docx file, use this skill. Do NOT use for PDFs, spreadsheets, Google Docs, or general coding tasks unrelated to document generation.
fcakyon/claude-codex-settings
xlsx
Use this skill any time a spreadsheet file is the primary input or output. This means any task where the user wants to: open, read, edit, or fix an existing .xlsx, .xlsm, .csv, or .tsv file (e.g., adding columns, computing formulas, formatting, charting, cleaning messy data); create a new spreadsheet from scratch or from other data sources; or convert between tabular file formats. Trigger especially when the user references a spreadsheet file by name or path — even casually (like "the xlsx in my downloads") — and wants something done to it or produced from it. Also trigger for cleaning or restructuring messy tabular data files (malformed rows, misplaced headers, junk data) into proper spreadsheets. The deliverable must be a spreadsheet file. Do NOT trigger when the primary deliverable is a Word document, HTML report, standalone Python script, database pipeline, or Google Sheets API integration, even if tabular data is involved.
fcakyon/claude-codex-settings
pptx
Use this skill any time a .pptx file is involved in any way — as input, output, or both. This includes: creating slide decks, pitch decks, or presentations; reading, parsing, or extracting text from any .pptx file (even if the extracted content will be used elsewhere, like in an email or summary); editing, modifying, or updating existing presentations; combining or splitting slide files; working with templates, layouts, speaker notes, or comments. Trigger whenever the user mentions "deck," "slides," "presentation," or references a .pptx filename, regardless of what they plan to do with the content afterward. If a .pptx file needs to be opened, created, or touched, use this skill.

dokploy-deploy
This skill should be used when user asks to "deploy with Dokploy", "use Dokploy Cloud", "manage self-hosted Dokploy", "deploy Docker Compose on Dokploy", "manage Dokploy databases", "configure Dokploy domains", or "look up Dokploy CLI commands".
