Unity async and coroutine correctness patterns. Catches common mistakes with Awaitable double-await, missing cancellation tokens, thread context after BackgroundThreadAsync, coroutine error swallowing, batch mode WaitForEndOfFrame, and Addressables handle leaks. PATTERN format: WHEN/WRONG/RIGHT/GOTCHA. Based on Unity 6.3 LTS documentation.
Unity 6 UI development guide. Use when building user interfaces, menus, HUD, buttons, or any UI elements. Covers UI Toolkit (recommended for new projects — USS, UXML, UI Builder, data binding), uGUI/Canvas (legacy runtime UI), and IMGUI. Based on Unity 6.3 LTS documentation.
Android development guidelines and best practices for the mobile-dev team

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.
