Software Mansion's best practices for production React Native and Expo apps on the New Architecture. MUST USE before writing, reviewing, or debugging ANY code in a React Native or Expo project. If the working directory contains a package.json with react-native, expo, or expo-router as a dependency, this skill applies. Trigger on: any code task in a React Native/Expo project, 'React Native', 'Expo', 'New Architecture', 'Reanimated', 'Gesture Handler', 'react-native-svg', 'ExecuTorch', 'react-native-audio-api', 'react-native-enriched-html', 'Worklet', 'Fabric', 'TurboModule', 'WebGPU', 'react-native-wgpu', 'TypeGPU', 'GPU shader', 'WGSL', 'svg', 'animation', 'gesture', 'audio', 'rich text', 'AI model', 'multithreading', 'chart', 'vector', 'image filter', 'shared value', 'useSharedValue', 'runOnJS', 'scheduleOnRN', 'thread', 'worklet', 'Bundle Mode', or any question involving UI, graphics, native modules, or React Native threading and animation behavior. Also use when a more specific sub-

TypeGPU is type-safe WebGPU in TypeScript. Use whenever the user writes, debugs, or designs TypeGPU code: 'use gpu' shader functions, tgpu.fn, buffers, textures, bind groups, compute and render pipelines, command encoders, render passes, render bundles, vertex layouts, slots, accessors, @typegpu/react hooks (useRoot, useFrame, useUniform), React Native worklet rendering, and any TypeGPU API. Shader logic and CPU-side resources are tightly coupled - handle both sides here even if the user only mentions one (e.g. "how do I write a shader", "how do I create a buffer"). Trigger on any mention of typegpu, tgpu, "use gpu", TypedGPU, or WebGPU code written using TypeGPU's schema API (d., tgpu., std.). Do NOT trigger for raw WebGPU (using GPUDevice/GPURenderPipeline directly without tgpu), WGSL-only questions, Three.js, Babylon.js, or WebGL.

Best practices for using Radon IDE's MCP tools when developing, debugging, and inspecting React Native and Expo apps. Use when interacting with a running app through Radon IDE - viewing screenshots, reading logs, inspecting the component tree, debugging network requests, reloading the app, or querying React Native documentation and library info. Trigger on: 'debug React Native', 'fix UI', 'network issues', 'build issues', 'Radon IDE', 'view screenshot', 'app logs', 'component tree', 'network inspector', 'reload app', 'React Native docs', 'library description', 'emulator', 'development viewport', 'viewscreenshot', 'viewapplicationlogs', 'viewcomponenttree', 'reloadapplication', 'viewnetworklogs', 'viewnetworkrequestdetails', 'querydocumentation', 'getlibrarydescription', and every request involving live app inspection, debugging or development in a Radon IDE session.

Software Mansion's guide for migrating Expo SDK apps to Meta Quest using expo-horizon packages. Use when adding Meta Quest or Meta Horizon OS support to an existing Expo or React Native project. Trigger on: Meta Quest, Horizon OS, Quest 2, Quest 3, Quest 3S, VR app, expo-horizon-core, expo-horizon-location, expo-horizon-notifications, build flavors for Quest, panel sizing, VR headtracking, Horizon App ID, quest build variant, isHorizonDevice, isHorizonBuild, migrate expo-location to Quest, migrate expo-notifications to Quest, Meta Horizon Store publishing, or any task involving running an Expo app on Meta Quest hardware.

Best practices for integrating and using RNRepo — Software Mansion's infrastructure for pre-built React Native library artifacts that reduces native build times by up to 2×. Use when setting up, configuring, or troubleshooting RNRepo in a React Native or Expo project. Trigger on: 'RNRepo', 'rnrepo', 'slow builds', 'build times', 'prebuilt artifacts', 'prebuilt libraries', '@rnrepo/expo-config-plugin', '@rnrepo/build-tools', 'prebuilds-plugin', 'rnrepo.config.json', 'DISABLERNREPO', 'packages.rnrepo.org', 'Maven prebuild', 'CocoaPods prebuild', 'xcframework prebuild', 'prebuild AAR', 'build from source', 'native compilation slow', 'Gradle plugin slow', 'pod install slow', 'CI build times'.

Complete onboarding guide for developers who are new to Detour, the open-source deferred deep linking SDK by Software Mansion. Use this skill whenever a user asks what Detour is, how to get started with Detour, how to set up deep linking with Detour, how to install the Detour SDK, how to configure the Detour dashboard, or how deferred deep linking works. Also use it when the user has no prior deep linking setup and wants to add deep links to their app. Covers everything from zero to production: account setup, dashboard configuration, Universal Links and App Links, platform SDK integration for React Native, iOS, Android, and Flutter, analytics, and architecture.

Software Mansion's Fishjam — hosted WebRTC platform for video, audio, one-to-many livestreaming, and compositions. MUST USE before writing, reviewing, or debugging ANY code that talks to a Fishjam instance from a backend (Node, Python) or a client (React web, React Native / Expo). Routes to platform fundamentals and the right SDK sub-skill. Trigger on: 'Fishjam', 'fishjam.io', 'fishjam.swmansion.com', 'fishjam dashboard', 'Fishjam ID', 'management token', 'peer token', 'sandbox API', 'livestream room', '@fishjam-cloud/js-server-sdk', 'fishjam-server-sdk', '@fishjam-cloud/react-client', '@fishjam-cloud/react-native-client', '@fishjam-cloud/ts-client', 'FishjamClient', 'FishjamProvider', 'FishjamNotifier', 'FishjamAgent', 'createPeer', 'createRoom', 'createAgent', 'createLivestreamStreamerToken', 'createMoqToken', 'refreshPeerToken', 'webhook', 'gemini fishjam', 'vapi fishjam', 'fishjam expo plugin', 'Fishjam composition', 'CompositionClient', 'forwardRoomTracks', '@fishjam-cloud/composi

Use when the user mentions migrating deep links, switching away from Branch or AppsFlyer, replacing their deep linking SDK, setting up Detour deep linking for the first time, or asks how Branch/AppsFlyer concepts map to Detour. Covers the complete migration end to end - Detour Dashboard configuration, Universal Links and App Links setup, SDK swap with code examples, and analytics migration. Works across Android, iOS, React Native, and Flutter.
