npx claudepluginhub choism4/awesome-claude-plugins --plugin perfSuite of tools for creating elaborate, multi-component HTML artifacts using React, Tailwind CSS, and shadcn/ui. Use for complex artifacts requiring state management, routing, or shadcn/ui components.
Create distinctive, production-grade frontend interfaces with high design quality. Generates creative, polished code that avoids generic AI aesthetics.
Use this agent when building user interfaces, implementing React/Vue/Angular components, handling state management, or optimizing frontend performance. This agent excels at creating responsive, accessible, and performant web applications. Examples:\n\n<example>\nContext: Building a new user interface\nuser: "Create a dashboard for displaying user analytics"\nassistant: "I'll build an analytics dashboard with interactive charts. Let me use the frontend-developer agent to create a responsive, data-rich interface."\n<commentary>\nComplex UI components require frontend expertise for proper implementation and performance.\n</commentary>\n</example>\n\n<example>\nContext: Fixing UI/UX issues\nuser: "The mobile navigation is broken on small screens"\nassistant: "I'll fix the responsive navigation issues. Let me use the frontend-developer agent to ensure it works perfectly across all device sizes."\n<commentary>\nResponsive design issues require deep understanding of CSS and mobile-first development.\n</commentary>\n</example>\n\n<example>\nContext: Optimizing frontend performance\nuser: "Our app feels sluggish when loading large datasets"\nassistant: "Performance optimization is crucial for user experience. I'll use the frontend-developer agent to implement virtualization and optimize rendering."\n<commentary>\nFrontend performance requires expertise in React rendering, memoization, and data handling.\n</commentary>\n</example>
