React Native with Expo framework for building native mobile apps on Android, iOS, and web from a single TypeScript codebase. Covers Expo Router file-based navigation (stack, tabs, drawer), EAS Build/Submit/Update for CI/CD and OTA updates, expo-dev-client for custom development builds, Expo Modules API for native Swift/Kotlin modules, core RN patterns (StyleSheet, FlatList, Platform-specific code), native device APIs (camera, notifications, haptics), and NativeWind for Tailwind CSS styling. Use when building React Native apps with Expo, configuring Expo Router navigation, setting up EAS Build pipelines, implementing OTA updates, creating native modules, or integrating device APIs like camera and push notifications.
Build native and cross-platform mobile applications for iOS and Android with optimized performance and platform integration. Use when you need SwiftUI or Jetpack Compose development, React Native or Flutter cross-platform apps, offline-first architecture, biometric authentication, push notifications, deep linking, app startup optimization, or mobile-specific UX patterns and gesture handling.
Build professional native macOS apps in Swift with SwiftUI and AppKit. Full lifecycle - build, debug, test, optimize, ship. CLI-only, no Xcode.
Guides wallet developers through integrating WalletConnect Pay SDK into mobile wallets (Kotlin, Swift, React Native, Flutter). Use when adding WC Pay payment acceptance, implementing pay link detection, handling USDC payment flows, or troubleshooting Pay SDK integration issues.
Guides the agent through adding Swift Package Manager (SPM) support to an existing Capacitor plugin. Covers creating a Package.swift manifest, replacing Objective-C bridge files with the CAPBridgedPlugin Swift protocol, updating .gitignore for SPM artifacts, cleaning up the Xcode project file, and updating package.json. Do not use for Capacitor app projects, creating new plugins from scratch, or non-Capacitor plugin frameworks.
Adding stable accessibility identifiers for screenshot automation across all frameworks. Covers Flutter, SwiftUI, UIKit, Jetpack Compose, XML Android, and React Native. Naming conventions, common widget patterns, and verification strategies.
Inspect an existing repo and generate OpenEditor onboarding config for it. Use when Codex needs to make a project OpenEditor-compatible by inferring framework or platform from the file tree, creating or updating `.logic-editor.json`, creating `oe-swift.json` for iOS or SwiftUI projects, or explaining which config fields still need manual confirmation.
Use when the user needs mobile app design and development patterns for React Native, Flutter, or SwiftUI — including platform HIG compliance, gestures, and offline-first architecture. Triggers: user says "mobile", "iOS", "Android", "React Native", "Flutter", "SwiftUI", "app design", "mobile navigation", "touch targets", "offline-first".
Design and implement integration architectures connecting financial systems — APIs, FIX protocol, ISO 20022, event-driven patterns, batch feeds, idempotency, and resilience. Use when building custodian integration pipelines, implementing FIX connectivity for order routing, designing ISO 20022 or SWIFT migration messaging, building batch file processing for custodian feeds or EOD reconciliation, implementing idempotency for transaction APIs, designing retry or circuit breaker patterns, mapping data between systems with different schemas, or troubleshooting integration failures causing recon breaks. Trigger on: FIX protocol, ISO 20022, custodian feed, batch processing, API design, idempotency, circuit breaker, dead letter queue, data mapping, integration architecture, SWIFT migration, mTLS, file feed, event-driven, message broker.
UI/UX design intelligence for web and mobile. Includes 50+ styles, 161 color palettes, 57 font pairings, 161 product types, 99 UX guidelines, and 25 chart types across 10 stacks (React, Next.js, Vue, Svelte, SwiftUI, React Native, Flutter, Tailwind, shadcn/ui, and HTML/CSS). Actions: plan, build, create, design, implement, review, fix, improve, optimize, enhance, refactor, and check UI/UX code. Projects: website, landing page, dashboard, admin panel, e-commerce, SaaS, portfolio, blog, and mobile app. Elements: button, modal, navbar, sidebar, card, table, form, and chart. Styles: glassmorphism, claymorphism, minimalism, brutalism, neumorphism, bento grid, dark mode, responsive, skeuomorphism, and flat design. Topics: color systems, accessibility, animation, layout, typography, font pairing, spacing, interaction states, shadow, and gradient. Integrations: shadcn/ui MCP for component search and examples.
Build beautiful iOS SwiftUI interfaces. Use this skill when the user asks to create, design, build, or fix any iOS screen, component, or view. Produces production-grade SwiftUI code with Apple Design Award-quality aesthetics using Liquid Glass (iOS 26+). Applies to any iOS UI task - new screens, redesigns, fixing ugly UI, share sheets, modals, cards, buttons, or full app interfaces.
Deliver cross-platform and native mobile experiences across React Native, Flutter, SwiftUI, and Jetpack Compose without collapsing mobile work into a single framework.
