Develop React Native or Flutter apps with native integrations. Use for mobile development, cross-platform code, or app optimization.
TanStack Query v5 server state management for React. Covers query/mutation patterns, v4-to-v5 migration (object syntax, gcTime, isPending, keepPreviousData), optimistic updates via useMutationState, SSR/hydration with HydrationBoundary, infinite queries, offline/PWA support, error boundaries with throwOnError, and React 19 Suspense integration. Use when building data fetching, fixing migration errors, debugging hydration mismatches, implementing caching strategies, or configuring mutations.
Convex backend development patterns, validators, indexes, actions, queries, mutations, file storage, scheduling, React hooks, and components. Use when writing Convex code, debugging Convex issues, or planning Convex architecture.
React performance optimization patterns including memoization, code splitting, bundle size reduction, re-render elimination, and profiling. Covers React Compiler automatic optimization, manual memo/useMemo/useCallback targeting, React.lazy with Suspense, barrel file avoidance, content-visibility for large lists, startTransition for non-urgent updates, and React DevTools profiling. Use when optimizing React app performance, reducing bundle size, eliminating unnecessary re-renders, debugging slow components, code splitting, or profiling rendering bottlenecks. Use for performance audit, bundle analysis, re-render diagnosis, lazy loading, virtualization.
Build reactive backends with Convex functions, schema validation, auth integration, and deployment workflows.
Builds elaborate multi-component claude.ai HTML artifacts using React 18, TypeScript, Vite, Tailwind CSS, and shadcn/ui bundled into single-file deliverables. Use when asked to "create complex artifact", "build React artifact with routing", "use shadcn/ui components", "create stateful web app artifact", or "build multi-component frontend". Provides initialization scripts, development workflow, and Parcel bundling to create sophisticated single-HTML artifacts with state management and modern components. Works with React/TypeScript stack for claude.ai artifacts requiring complexity beyond simple HTML/JSX.
TanStack DB reactive client-side database with live queries and optimistic mutations. Use when building reactive UIs with local-first data, sync engines, or optimistic updates. Use for tanstack-db, live queries, optimistic mutations, sync engine, reactive database, local-first.
Swift Combine framework for reactive programming, handling asynchronous events with publishers, subscribers, and operators.
SwiftUI framework concepts including property wrappers, state management, and reactive UI patterns.
Use when adding interactive 3D scenes from Spline.design to web projects, including React embedding and runtime control API.
Interface Craft by Josh Puckett — a toolkit for building polished, animated interfaces in React. Includes Storyboard Animation (human-readable animation DSL with stage-driven sequencing), DialKit (live control panels for tuning animation values), and Design Critique (systematic UI review based on Josh Puckett's methodology). Triggers on: animate, animation, transition, storyboard, entrance, motion, spring, easing, timing, dialkit, sliders, controls, tune, tweak, critique, review, feedback, audit, improve, polish, refine, redesign.
React and Next.js performance optimization from Vercel Engineering. Use when building React components, optimizing performance, eliminating waterfalls, reducing bundle size, reviewing code for performance issues, or implementing server/client-side optimizations.
