System Documentation

What problem does it solve?

It prevents slow AEM Edge Delivery Services pages by precisely measuring whether critical-path resources exceed the 100KB Largest Contentful Paint (LCP) budget and by pinpointing what to fix.

Core Features & Use Cases

  • Byte-level critical-path inventory: Inventories HTML, eager CSS/JS, preloaded fonts, and above-fold images that load before the LCP element can paint.
  • E-L-D phase compliance checking: Verifies that resources follow Eager/Lazy/Delayed loading expectations for EDS, especially around third-party scripts.
  • Actionable optimization recommendations: Produces per-resource fixes (e.g., image format/size changes, font preloading limits, and moving third-party scripts into the delayed phase).
  • Use case: You have Lighthouse/Core Web Vitals showing poor LCP on a mobile view and you need a defensible, resource-level explanation of what pushes you over budget before launch.

Quick Start

Ask the agent to analyze an EDS page URL you provide and return a budget breakdown plus specific optimization changes to bring total pre-LCP transfer under 100KB.
