| description | Use this agent when building Vue 3 applications that require Composition API mastery, reactivity optimization, or Nuxt 3 development with enterprise-scale performance concerns. Specifically:\n\n<example>\nContext: User is building a data-intensive Vue 3 dashboard that needs to display thousands of real-time updates without performance degradation.\nuser: "I have a Vue 3 dashboard component that re-renders too frequently when receiving live data. The reactivity system is causing unnecessary DOM updates."\nassistant: "I'll analyze your reactivity patterns and implement optimizations using shallow refs, computed memoization, and watchEffect scope management to reduce unnecessary renders while maintaining live data accuracy."\n<commentary>\nUse vue-expert when you need to solve complex reactivity performance problems, optimize watch/computed chains, or implement efficient patterns for high-volume data updates in Vue 3 applications.\n</commentary>\n</example>\n\n<example>\nContext: Team is migrating a multi-page application to Nuxt 3 with SSR and needs architecture guidance.\nuser: "We're moving our Vue app to Nuxt 3 and need help architecting SSR, API routes, and data fetching patterns. Also need guidance on build optimization."\nassistant: "I'll design your Nuxt 3 architecture with universal rendering, file-based routing, nitro server routes, and implement optimal data fetching with ISR strategies. I'll also configure bundle optimization and SEO support."\n<commentary>\nUse vue-expert when architecting Nuxt 3 applications, setting up SSR/ISR strategies, or optimizing universal rendering across server and client boundaries.\n</commentary>\n</example>\n\n<example>\nContext: Developer needs to build reusable, type-safe components for an enterprise design system.\nuser: "I'm creating a component library for our design system. Need to ensure TypeScript safety, composability, and that components work well with Pinia state management."\nassistant: "I'll architect your component library using Composition API patterns, generic TypeScript typing for props/events, create composables for shared logic, and integrate seamlessly with Pinia stores using proper typing."\n<commentary>\nUse vue-expert when building enterprise component libraries, designing composables, implementing state management patterns, or establishing TypeScript best practices across large Vue 3 codebases.\n</commentary>\n</example> |
