Search 21st.dev component registry for production-ready React components. Finds components by natural language description, filters by framework and style system, returns ranked results with install instructions. Use when looking for UI components, finding alternatives to existing components, or sourcing design system building blocks.
LOAD THIS SKILL when: user says 'use fe design skill', creating UI components, designing pages/layouts, working on styling/CSS, or mentions 'design', 'UI', 'component', 'layout', 'styling'. Creates distinctive production-grade interfaces avoiding generic AI aesthetics.
Intelligent network quality analysis with adaptive loading strategies. Detects connection type (2g/3g/4g), bandwidth, RTT, and save-data mode, then automatically triggers appropriate optimization workflows. Includes decision trees that recommend image compression for slow connections, critical CSS inlining for high RTT, and save-data optimizations (disable autoplay, reduce quality). Features connection-aware performance budgets (500KB for 2g, 1.5MB for 3g, 3MB for 4g+) and adaptive loading implementation guides. Cross-skill integration with Loading (TTFB impact), Media (responsive images), and Core Web Vitals (connection impact on LCP/INP). Use when the user asks about slow connections, mobile optimization, save-data support, or adaptive loading strategies. Compatible with Chrome DevTools MCP.
Intelligent interaction performance analysis with automated workflows for INP debugging, scroll jank investigation, and main thread blocking. Includes decision trees that automatically run script attribution when long frames detected, break down input latency phases, and correlate layout shifts with interactions. Features workflows for complete interaction audit, third-party script impact analysis, and animation performance debugging. Cross-skill integration with Core Web Vitals (INP/CLS correlation) and Loading (script execution analysis). Use when the user asks about slow interactions, janky scrolling, unresponsive pages, or INP optimization. Compatible with Chrome DevTools MCP.
Intelligent media optimization with automated workflows for images, videos, and SVGs. Includes decision trees that detect LCP images (triggers format/lazy-loading/priority analysis), identify layout shift risks (missing dimensions), and flag lazy loading issues (above-fold lazy or below-fold eager). Features workflows for complete media audit, LCP image investigation, video performance (poster optimization), and SVG embedded bitmap detection. Cross-skill integration with Core Web Vitals (LCP/CLS impact) and Loading (priority hints, resource preloading). Provides performance budgets and format recommendations based on content type. Use when the user asks about image optimization, LCP is an image/video, layout shifts from media, or media loading strategy. Compatible with Chrome DevTools MCP.
Intelligent loading performance analysis with automated workflows for TTFB investigation (DNS/connection/server breakdown), render-blocking detection, script performance deep dive (first vs third-party attribution), font optimization, and resource hints validation. Includes decision trees that automatically analyze TTFB sub-parts when slow, detect script loading anti-patterns (async/defer/preload conflicts), identify render-blocking resources, and validate resource hints usage. Features workflows for complete loading audit (6 phases), backend performance investigation, and priority optimization. Cross-skill integration with Core Web Vitals (LCP resource loading), Interaction (script execution blocking), and Media (lazy loading strategy). Use when the user asks about TTFB, FCP, render-blocking, slow loading, font performance, script optimization, or resource hints. Compatible with Chrome DevTools MCP.
Create award-winning, immersive web experiences at the level of Awwwards-featured agencies. Use when the user mentions "premium website", "portfolio site", "scroll animations", "Awwwards quality", or "brand experience". Covers dramatic typography, purposeful motion, scroll-based composition, and performance-optimized animation. For foundational UI, see refactoring-ui. For type selection, see web-typography. Trigger with 'top', 'design'.
AI Elements component library guidance — pre-built React components for AI interfaces built on shadcn/ui. Use when building chat UIs, message displays, tool call rendering, streaming responses, reasoning panels, or any AI-native interface with the AI SDK.
Crée des interfaces frontend distinctives, de qualité production, avec un haut niveau de design. À utiliser quand l'utilisateur demande de construire des composants web, pages, artefacts, posters ou applications (exemples : sites web, landing pages, dashboards, composants React, mises en page HTML/CSS, ou pour styliser/embellir toute interface web). Génère du code créatif et soigné qui évite l'esthétique générique de l'IA.
TypeScript language expertise covering the type system, generics, utility types, advanced type patterns, and project configuration. Use this skill whenever writing, reviewing, or refactoring TypeScript code, designing type-safe APIs, working with complex generics, debugging type errors, configuring tsconfig.json, migrating JavaScript to TypeScript, or leveraging TypeScript 5.x features like satisfies, const type parameters, decorators, and the using keyword. Also use when the user asks about type narrowing, conditional types, mapped types, template literal types, branded types, discriminated unions, or any TypeScript type system question — even seemingly simple ones, because TypeScript's type system has subtle gotchas that catch experienced developers.
Build Progressive Web Apps (PWAs) with offline support, installability, and caching strategies. Trigger whenever the user mentions PWA, service workers, web app manifests, Workbox, 'add to home screen', or wants their web app to work offline, feel native, or be installable.
Front-end routing specification, including routing file organization structure, dynamic routing generation, static auxiliary routing writing, RouteMeta meta information fields, and routing guard logic. Suitable for projects based on vue-vben-admin v5. This skill is used when you need to add new routes, configure routing permissions, write routing guards, or modify routing-related files.
