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.

Triggers on: Color, ColorSource, hex, rgb, hsl, tint, premultiply, Color.shared, color conversion.
Build modern web applications with React, Vue, Angular, or Svelte, focusing on performance and accessibility. Use when you need component library development, TypeScript UI implementation, responsive layouts with CSS Grid and Flexbox, Core Web Vitals optimization, service worker offline support, code splitting, ARIA accessibility, Storybook integration, or frontend API client architecture.
Generates complete, production-ready SaaS project boilerplate including authentication, database schemas, billing integration, API routes, and a working dashboard using Next.js 14+ App Router, TypeScript, Tailwind CSS, shadcn/ui, Drizzle ORM, and Stripe.
