Use when: setting up data fetching in React projects, migrating from v4 to v5, or fixing object syntax required errors, query callbacks removed issues, cacheTime renamed to gcTime, isPending vs isLoading confusion, keepPreviousData removed problems.
Design and build reusable, well-documented components. Master component composition, prop design, variant systems, state management, and documentation. Create a scalable component library that enables consistency and speeds up development. Works with React, TypeScript, and Tailwind CSS.
Use when creating React components, structuring component files, organizing component code, debugging React hooks issues, or when asked to "create a React component", "structure this component", "review component structure", "refactor this component", "fix infinite loop", or "useEffect not working". Applies to both TypeScript and JavaScript React components. Includes hooks antipatterns.
Provides one-command project creation for React Native including project initialization, configuration, and template generation. Use when the user asks about creating React Native projects, needs to initialize a new React Native project, or generate React Native project structure.
React 19 patterns including Server Components, Actions, Suspense, hooks, and component composition
Responsive design with Container Queries, fluid typography, cqi/cqb units, and mobile-first patterns for React applications. Use when building responsive layouts or container queries.
Load PROACTIVELY when task involves optimizing speed, reducing bundle size, or improving responsiveness. Use when user says "make it faster", "reduce bundle size", "fix slow queries", "optimize rendering", or "check Core Web Vitals". Covers bundle analysis and tree-shaking, database query optimization (N+1, indexing), React rendering performance (re-renders, memoization), network waterfall optimization, memory leak detection, server-side performance, and Core Web Vitals (LCP, FID, CLS) improvement.
Provides naming conventions and Props type definition patterns for React components. Defines naming rules for file names and component names, Props type definitions using the ComponentNameProps pattern, and best practices for React 19. Use this when referencing component creation, naming convention checks, Props type definition, refactoring, and ESLint/TypeScript error resolution.
Prowler UI-specific patterns. For generic patterns, see: typescript, react-19, nextjs-15, tailwind-4. Trigger: When working inside ui/ on Prowler-specific conventions (shadcn vs HeroUI legacy, folder placement, actions/adapters, shared types/hooks/lib).
Teaches what React Compiler handles automatically in React 19, reducing need for manual memoization. Use when optimizing performance or deciding when to use useMemo/useCallback.
React hooks for Ethereum and EVM blockchain interactions using Wagmi v3. Use when building React or Next.js apps with wallet connections, contract reads/writes, or blockchain state. Triggers on useAccount, useConnect, useContractRead, useContractWrite, WagmiProvider, ConnectKit, RainbowKit, or any React blockchain hooks. Do NOT use for Node scripts or non-React code (use viem skill instead).
