State management with Zustand for Remix/React applications. Covers store creation, TypeScript patterns, persistence, and Shopify-specific state patterns.
Scaffold class-based Zustand stores with flattenActions: web (component-level store + Context + Provider) and core (slice-based store with immer). Class-based actions provide Go-to-Definition DX, #private field encapsulation, and prototype-safe slice composition.
Load PROACTIVELY when task involves application state, data fetching, or form handling. Use when user says "manage state", "add data fetching", "set up Zustand", "handle form validation", or "add React Query". Covers server state (TanStack Query with caching, optimistic updates), client state (Zustand stores), form state (React Hook Form with Zod validation), URL state (search params, routing), and choosing between state solutions.
Expert React developer specializing in React 18+, Next.js ecosystem, and modern React patterns. This agent excels at building performant, scalable React applications using hooks, concurrent features, state management solutions like Zustand, and data fetching with TanStack Query.
Frontend implementation guide for React 19 + TypeScript + Vite 8 monorepo projects. Covers tech stack, project structure (bun workspaces), state management (TanStack Query for async requests + Zustand for client state), UI (shadcn/ui + Tailwind CSS 4.2), theming (light/dark/system), i18n (react-i18next), routing (React Router 7), and coding conventions. Use when scaffolding, developing, or reviewing frontend web applications.
Production-grade frontend engineering for Next.js/React, Vue/Nuxt, Angular, Svelte/SvelteKit, Remix, and Vite+React. Use for framework selection, App Router/RSC patterns, TypeScript strict-mode UI code, Tailwind CSS v4 + shadcn/ui, state/data flows (TanStack Query, Zustand), forms validation, testing (Vitest/Testing Library/Playwright), performance (Core Web Vitals), and accessibility (WCAG 2.2).
Skill for implementing actual UI and integrating with APIs. Covers frontend-backend integration, state management, and API client architecture.

Guide feature development for React applications with architecture focus. Covers Zustand/Redux patterns, IndexedDB usage, component systems, lazy loading strategies, and seamless integration. Use when adding new features, refactoring existing code, or planning major changes.
Apply preferred toolchain and technology stack defaults: pnpm, Next.js, TypeScript, Convex, Vercel, Tailwind, shadcn/ui, Zustand, TanStack, Vitest. Use when setting up new projects, choosing dependencies, discussing stack decisions, or evaluating alternatives.
Production patterns for managing complex application state in React without Redux, Zustand, or other state libraries. Includes multi-stage loading, command patterns, refs for performance, and parallel data fetching. Use when building complex UIs with interconnected states, need loading stages and progress tracking, or implementing command patterns.
