expo-project-structure provides a starter folder layout for new expo apps using expo router, with clear separation between routes, components, screens, and server code. includes platform-specific file handling and colocated test patterns.

native-data-fetching covers expo networking patterns including fetch, react query setup, error handling, authentication with secure token storage, offline support via netinfo, environment configuration, and request cancellation. comprehensive procedural examples anchor most patterns.

expo-api-routes provides step-by-step guidance for building secure server-side endpoints in Expo Router with EAS Hosting. covers file structure, HTTP methods, environment variables, CORS, and deployment to Cloudflare Workers with explicit runtime constraints.

expo-data-fetching covers fetch api, react query, authentication, offline support, and environment configuration for expo apps. includes error handling patterns, token refresh, and network debugging guidance.

eas-simulator provisions remote iOS/Android simulators on Expo cloud for testing, particularly useful in non-macOS environments or when local simulation isn't viable. requires recent eas-cli and incurs compute costs against your plan.

expo-deployment covers building and submitting expo apps to ios app store, google play store, and testflight via eas, with configuration templates and platform-specific guidance.

expo-web-to-native provides a phased migration framework for porting existing react web applications to ios and android by progressively replacing web screens with native implementations using the strangler fig pattern.

eas-hosting covers deploying expo web apps and api routes to cloudflare workers via eas deploy. covers paid hosting model, api route authoring decisions, and basic deployment workflow.

eas-observe covers setup, querying, and interpretation of expo's production performance monitoring service, with references organized by use case (setup, cli queries, metric diagnostics).

expo-ui-jetpack-compose bridges jetpack compose views into react native expo apps. mirrors compose's api surface, requires type file inspection and sdk 55 documentation cross-reference for accurate component usage.

expo-app-clip guides adding an iOS App Clip target to Expo projects with URL-based invocation via AASA files, requiring Apple Developer membership and HTTPS hosting for production deployment.

expo-tailwind-setup configures tailwind css v4 in expo projects via nativewind v5 and react-native-css, enabling cross-platform className styling for native and web components.

expo-module documents when to reach for native modules and views via the expo modules api, covering swift, kotlin, and typescript, but lacks procedural depth and failure mode coverage.

building-native-ui aggregates expo and react native conventions covering routing, styling, colors, navigation, and component preferences. heavy on reference links but lacks cohesive walkthrough of building an actual app.

expo-cicd-workflows covers writing and validating EAS workflow YAML with schema fetching and dynamic expression support, but lacks concrete step sequences and failure handling guidance.

expo-examples documents how to extract integration patterns from expo's ~70 example projects, mapping user needs to with-* directories and adapting canonical dependency/config setups into existing or new applications.

expo-skill-eval is a testing harness for expo plugin skills covering trigger accuracy, code quality, and runtime rendering. the skill describes infrastructure and configuration requirements but lacks actionable procedures and explicit failure handling.

eas-app-stores provides ios app store, google play, and testflight deployment for expo apps via the paid eas service, with reference materials for workflows, submission, and metadata management.

expo-router covers file-based routing, dynamic routes, groups, and navigation patterns. reference-heavy structure with incomplete actionable guidance and minimal failure mode documentation.

expo-dom bridges web libraries to native by rendering React web code in webviews on ios/android while preserving web semantics. enables incremental migration of existing web components without rewriting.
