Code splitting and lazy loading with React.lazy, Suspense, route-based splitting, intersection observer, and preload strategies for optimal bundle performance. Use when implementing lazy loading or preloading.
Prevent N+1 queries by eager loading; enable lazy-loading protection in non-production; choose selective fields

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.
Angular 20+ performance optimization guidelines with Signals, httpResource, signal inputs/outputs, @defer, and native control flow (@if, @for). Use when writing, reviewing, or refactoring modern Angular code. Triggers on tasks involving Angular components, services, data fetching, bundle optimization, or performance improvements.
Implement routing in Angular v20+ applications with lazy loading, functional guards, resolvers, and route parameters. Use for navigation setup, protected routes, route-based data loading, and nested routing. Triggers on route configuration, adding authentication guards, implementing lazy loading, or reading route parameters with signals.
React and Vite performance optimization guidelines. Use when writing, reviewing, or optimizing React components built with Vite. Triggers on tasks involving Vite configuration, build optimization, code splitting, lazy loading, HMR, bundle size, or React performance.
ALWAYS use when optimizing Angular applications for performance, change detection, bundle size, lazy loading, or runtime performance.
ALWAYS use when working with Angular Deferrable Views, @defer, lazy loading components, or deferred loading in Angular.
ALWAYS use when working with Angular Router, routing configuration, guards, resolvers, lazy loading, or navigation in Angular applications.
Implement performant responsive images with srcset, sizes, lazy loading, and modern formats (WebP, AVIF). Covers aspect-ratio for CLS prevention, picture element for art direction, and fetchpriority for LCP optimization. Use when: adding images to pages, optimizing Core Web Vitals, preventing layout shift, implementing art direction, or converting to modern formats.
Optimize web application performance using code splitting, lazy loading, caching, compression, and monitoring. Use when improving Core Web Vitals and user experience.
