jsi

React Native JSI (JavaScript Interface) — C++ API for interacting with the JS runtime. Use whenever the user asks about or writes C++ code that touches JSI types or patterns: jsi::Runtime, jsi::Value, jsi::Object, jsi::Function, jsi::Array, jsi::ArrayBuffer, jsi::String, jsi::Symbol, jsi::BigInt, jsi::PropNameID, jsi::HostObject, jsi::HostFunction, jsi::NativeState, jsi::WeakObject, jsi::Scope, JSIException, JSINativeException, JSError, HostFunctionType, createFromHostFunction, getHostObject, setNativeState, evaluateJavaScript, queueMicrotask, drainMicrotasks, setRuntimeData, getRuntimeData, ISerialization, rt.global(), jsi.h, jsi-inl.h, JSI binding, C++ native module, calling JS from C++, calling C++ from JS, HostObject destructor, shared_ptr, CallInvoker, invokeAsync, folly::dynamic with JSI, zero-copy ArrayBuffer, TurboModule C++ layer, Nitro Module, jsi::WithRuntimeDecorator, or any question about the boundary between C++ and the JavaScript engine in React Native.

multithreading

Software Mansion's best practices for multithreading in React Native apps using react-native-worklets. Use when running JavaScript on multiple threads, offloading heavy computation from the JS thread, communicating between runtimes, or sharing data across threads. Trigger on: 'worklet', 'worklets', 'react-native-worklets', 'runOnUI', 'runOnJS', 'scheduleOnUI', 'scheduleOnRN', 'scheduleOnRuntime', 'createWorkletRuntime', 'background thread', 'UI thread', 'worker runtime', 'Serializable', 'Synchronizable', 'multithreading', 'parallel execution', 'offload computation', 'background processing', 'Bundle Mode', or any request to move work off the JS thread in a React Native app.

native-data-fetching

Use when implementing or debugging ANY network request, API call, or data fetching. Covers fetch API, React Query, SWR, error handling, caching, offline support, and Expo Router data loaders (`useLoaderData`).

on-device-ai

Best practices for building on-device AI features in React Native using React Native ExecuTorch. Use when the user wants to add AI to a mobile app without cloud dependencies: chatbots and assistants, image classification, object detection, OCR and document parsing, style transfer, image generation, speech-to-text, text-to-speech, voice activity detection, semantic search with embeddings, real-time camera AI with VisionCamera, or vision-language image understanding. Also use when the user mentions offline AI, on-device ML, privacy-preserving AI, reducing cloud API costs or latency, running models locally on mobile, or downloading and managing ML models. Covers react-native-executorch hooks (useLLM, useClassification, useObjectDetection, useOCR, useSemanticSegmentation, useInstanceSegmentation, useStyleTransfer, useTextToImage, useImageEmbeddings, useSpeechToText, useTextToSpeech, useVAD, useTextEmbeddings, useExecutorchModule), tool calling, structured output, VLMs, model loading, and resource management.

rich-text

Software Mansion's best practices for rich text in React Native using react-native-enriched and react-native-enriched-markdown. Use when building rich text editors, formatted text inputs, Markdown renderers, or any feature requiring inline styling, mentions, links, structured text editing, or Markdown display. Trigger on: 'rich text editor', 'rich text input', 'text editor', 'react-native-enriched', 'react-native-enriched-markdown', 'EnrichedTextInput', 'EnrichedMarkdownText', 'formatted text input', 'WYSIWYG', 'mentions input', 'text formatting toolbar', 'markdown renderer', 'markdown display', 'render markdown', 'display markdown natively', 'LaTeX math', 'GFM tables', or any request to build rich text editing or Markdown rendering in React Native.

Use Expo DOM components to run web code in a webview on native and as-is on web. Migrate web code to native incrementally.

vercel-react-native-skills

React Native and Expo best practices for building performant mobile apps. Use when building React Native components, optimizing list performance, implementing animations, or working with native modules. Triggers on tasks involving React Native, Expo, mobile performance, or native platform APIs.

react-native-best-practices

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', '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', or any question involving UI, graphics, native modules, or React Native threading and animation behavior. Also use when a more specific sub-skill matches.

typegpu

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, vertex layouts, slots, accessors, 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.
