PostHog integration for Expo applications
API reference: Core Animation (QuartzCore). Query for CALayer, CAAnimation, CABasicAnimation, CAKeyframeAnimation, CASpringAnimation, CATransaction, CAShapeLayer, CAGradientLayer, CAEmitterLayer, CATransform3D, CADisplayLink.
Diagnose and resolve RevenueCat integration issues — inspects dashboard configuration through the RevenueCat MCP, walks the SDK debug logs, and covers code-side gotchas. Use when the user says offerings are empty, products not loading, entitlement not active after purchase, paywall won't load, transactions not appearing, customer info shows no entitlements, sandbox purchase not working, or RevenueCat is broken on iOS, Android, Kotlin Multiplatform, Flutter, or React Native.
Set up a complete RevenueCat project from scratch — creates apps, products, entitlements, offerings, and packages in the correct order.
Use this skill to integrate the Jetpack Compose Styles API into an Android project. This skill guides you through upgrading dependencies, setting up component themes, making custom components styleable, and migrating existing layout properties to use unified styles. Migrate custom design system components, replace hard coded parameters with Style attributes, and use Modifier.styleable for interaction states.
Use when deciding where Jetpack Compose UI element state or UI logic should live: local remember state, hoisted composable parameters, a plain state holder class, or a screen-level ViewModel/component.
Use this skill to scaffold new Expo / React Native design system components that obey the expo-design-system rules by construction — a variant-driven pressable primitive, a slot-based card surface, a typed text primitive, a labeled form field, a FlashList entity screen, a theme token group, and a Storybook variant catalog. Trigger whenever the user wants to create, add, generate, or scaffold a new shared UI component, primitive, design token group, or screen for the clinic mobile app, even if they don't mention the design system — the generated code uses Unistyles v3 variants instead of style props, ref-as-prop, design tokens, built-in accessibility, and web/iOS parity (`_web` hover/focus/cursor on interactive primitives), so it follows expo-design-system without rework. Output is TSX/TS using react-native-unistyles.
Guides the agent through creating and maintaining Capacitor plugins from scratch. Covers scaffolding a new plugin project, designing the TypeScript API, implementing native iOS (Swift) and Android (Java/Kotlin) bridges, implementing the web layer, defining TypeScript type definitions, plugin configuration values, plugin hooks, development workflow with local testing, documentation generation, and publishing to npm. Do not use for installing existing plugins into an app, upgrading existing plugins to newer Capacitor versions, adding SPM support to plugins, or non-Capacitor plugin frameworks.
HarmonyOS application development assistant based on ArkTS and ArkUI frameworks. Confirm API version (default API 20+) and target device type (default PC) before starting. Supports UI component development, data management, network communication, and system capability integration. Applicable for greenfield development, iterating existing projects, and architecture design. References official Huawei documentation including release notes, development guides, API references, best practices, and FAQ.
Full-pipeline iOS App Store opportunity research. Discovers underserved niches, analyzes competitor gaps, estimates revenue, produces scored top-3 opportunity reports, and writes MVP PRDs — all through browser and web research. Use when the user wants to find profitable iOS app ideas, research App Store charts, analyze competitor apps (ratings, reviews, revenue, gaps), generate opportunity reports, or write MVP PRDs. Triggers on "find app opportunities", "app store research", "what app should I build", "research this app category", "find a gap in the app store", "ios app ideas".
The entry point for building any Salesforce native mobile app on iOS or Android. TRIGGER when the user says: "build a Salesforce iOS app", "add Salesforce login to my Android app", "set up Mobile SDK", "add MobileSync / SmartStore offline storage", "embed an Agentforce agent in my mobile app", "add Agentforce chat to iOS/Android", or otherwise asks to create, extend, or integrate a Salesforce mobile experience in Swift or Kotlin (MSDK, Agentforce SDK, or both). SKIP when the user is building a non-Salesforce mobile app, using React Native / Flutter / Ionic without Salesforce integration, asking about generic mobile UI design, or working on a Salesforce-adjacent web/desktop surface (LWC, Experience Cloud, Mobile Publisher branding-only).
