Analyzes and improves website performance by diagnosing Core Web Vitals, render-blocking resources, and network dependencies to deliver faster, more reliable user experiences.
Audit a target page to generate a performance report with Core Web Vitals and actionable optimization recommendations.
High-intent search queries and answers about installing and using this skill.
To audit Core Web Vitals for a URL, this skill measures FCP, LCP, TBT, CLS, and Speed Index to identify performance bottlenecks. It estimates impact on user-perceived performance and generates an actionable optimization plan.
Finding render-blocking resources and network dependencies involves detecting blocking scripts, styles, dependency chains, caching gaps, and large assets. This skill analyzes network dependencies to pinpoint latency contributors harming load times.
The best way to profile a slow landing page is to surface top latency contributors and generate a prioritized fix plan. This skill audits the target URL to provide concrete optimization steps aligned with development workflows.
Yes, the performance audit provides actionable recommendations and steps to reproduce improvements across common frameworks and hosting setups. It ensures optimization steps align directly with your existing development workflows and tooling.
Yes, you can use MCP tooling to measure real user pages for caching gaps and render-blocking issues. The skill applies this tooling to audit target URLs and quantify web performance issues affecting user experience.
A high Total Blocking Time in a web performance audit indicates main-thread bottlenecks from render-blocking scripts. This skill identifies these network dependencies and provides concrete optimization steps to reduce latency.
