Build 3D applications with React Three Fiber (R3F), the React renderer for Three.js. Use this skill when building 3D scenes with React, using declarative JSX for 3D objects, integrating Three.js with React state/lifecycle, or using Drei helpers. Covers Canvas setup, hooks, Drei utilities, performance patterns, and state management for 3D React apps.
Build on-device AI into React Native apps using ExecuTorch. Provides hooks for LLMs, computer vision, OCR, audio processing, and embeddings without cloud dependencies. Use when building AI features into mobile apps - AI chatbots, image recognition, speech processing, or text search.
Use when writing, reviewing, or refactoring React component tests with Testing Library. Load when you see render(), screen, fireEvent, userEvent, waitFor, or *.test.tsx files. Covers query priority (getByRole > getByLabelText > getByText), user-centric testing patterns, async utilities, custom renders with providers, and accessibility-first assertions. Keywords include RTL, Testing Library, screen, getByRole, findBy, queryBy, userEvent, waitFor, toBeInTheDocument, testing-library/react, testing-library/user-event, jest-dom.
Use when "building React artifacts", "creating HTML artifacts", "bundling React apps", "single HTML file", or asking about "artifact builder", "shadcn components", "Tailwind artifacts"
Create distinctive, production-grade frontend interfaces with high design quality. Use when building web components, pages, or applications. Includes framework-specific guidance for Tailwind, React, Vue, and Rails/Hotwire ecosystems.
Implement the Syncfusion React Chat UI component. Use this skill to create and customize messaging interfaces, including chat setup, message rendering, file attachments, typing indicators, conversation layout, theming, event handling, and real-time updates in React applications.
Implement the Syncfusion React AutoComplete component for type-ahead suggestions and filtered dropdowns. Use this when working with AutoComplete input fields, local or remote data binding, filtering strategies, item/group templates, or virtualization in React applications. This skill covers installation, data binding, filtering, grouping, accessibility (WAI-ARIA), and API usage for ej2-react-dropdowns AutoComplete.
Audits a React SPA project against architecture rules. Use when asked to "review components", "check architecture", "audit this react project", "does this follow react rules", or "review my frontend structure".
Expo and React Native done right. Expo Router, EAS Build, native modules, platform-specific patterns, and navigation.
Provides exact Enzyme → React Testing Library migration patterns for React 18 upgrades. Use this skill whenever Enzyme tests need to be rewritten - shallow, mount, wrapper.find(), wrapper.simulate(), wrapper.prop(), wrapper.state(), wrapper.instance(), Enzyme configure/Adapter calls, or any test file that imports from enzyme. This skill covers the full API mapping and the philosophy shift from implementation testing to behavior testing. Always read this skill before rewriting Enzyme tests - do not translate Enzyme APIs 1:1, that produces brittle RTL tests.
React 18.3.1 and React 19 dependency compatibility matrix.
Provides the complete migration pattern for React legacy context API (contextTypes, childContextTypes, getChildContext) to the modern createContext API. Use this skill whenever migrating legacy context in class components - this is always a cross-file migration requiring the provider AND all consumers to be updated together. Use it before touching any contextTypes or childContextTypes code, because migrating only the provider without the consumers (or vice versa) will cause a runtime failure. Always read this skill before writing any context migration - the cross-file coordination steps here prevent the most common context migration bugs.
