What problem does it solve?

Astro sites frequently suffer from waterfalls, oversized bundles, and slow hydration. This skill provides a consolidated, prioritized set of rules to systematically reduce latency and improve Core Web Vitals.

Core Features & Use Cases

• 57 rules across 8 sections covering waterfalls elimination, bundle size optimization, server-side performance, client-side data fetching, re-render optimization, rendering performance, JavaScript performance, and advanced patterns.
• Apply sections selectively based on need (e.g., focus on Section 1 for waterfalls, Section 2 for bundles, Section 3 for SSR; combine with memoization and dynamic imports for best results).
• Use with the content map to navigate and implement targeted improvements in real projects.

Quick Start

• Open the Astro Performance Expert skill and start with Section 1 (Eliminating Waterfalls) and Section 2 (Bundle Size Optimization) to identify and fix the most impactful bottlenecks. Then proceed to Section 3 (Server-Side Performance) and Section 5 (Re-render Optimization) as needed.
