SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Manually identifying and fixing website performance bottlenecks is time-consuming and requires specialized knowledge of Lighthouse metrics and web performance best practices. This Skill eliminates that overhead by automating the full audit and remediation workflow.

Core Features & Use Cases

Automated Lighthouse Auditing: Runs full Lighthouse scans to generate performance, accessibility, best practices, and SEO scores, plus Core Web Vitals metrics with clear target thresholds.
Root Cause Identification: Pinpoints exact elements causing issues like slow LCP, high CLS, and unused resources, rather than just reporting generic warnings.
Automated Fixes: Applies common performance optimizations automatically, including preloading LCP images, adding image dimensions, deferring render-blocking scripts, and optimizing font loading.
Use Case: For example, if your SaaS landing page has a 3.2s LCP driving up bounce rates, this Skill will identify the unoptimized hero image as the root cause, add preload tags and WebP conversion recommendations, and bring the LCP below the 2.5s target.

Quick Start

Use the perf-audit skill to run a full performance audit on your production website and apply automated fixes for all detected performance issues.

Frequently Asked Questions about perf-audit

High-intent search queries and answers about installing and using this skill.

FAQPage Schema

How do I fix Core Web Vitals issues on my website automatically?▼

Fix Core Web Vitals issues by running automated Lighthouse scans that pinpoint root causes like slow LCP or high CLS and apply optimizations such as preloading LCP images and deferring render-blocking scripts.

How do I audit website performance without manually configuring Lighthouse?▼

Audit website performance without manual Lighthouse configuration by using an automated workflow that runs full scans, identifies exact elements causing render-blocking resources, and applies common fixes automatically.

What is the best way to optimize a slow LCP on a SaaS landing page?▼

The best way to optimize slow LCP is to identify the root cause element, such as an unoptimized hero image, and automatically apply preload tags and WebP conversion recommendations to bring LCP below the 2.5s target.

Does automated performance auditing work for staging environments?▼

Automated performance auditing works for both production and staging web properties, generating performance scores and applying remediation for unused assets and render-blocking resources without deep performance expertise.

Why does my website still have high CLS after running a performance audit?▼

High CLS persists after a performance audit when specific elements lack dimensions, but automated remediation can pinpoint these exact root causes and add missing image dimensions to resolve layout shifts.

How do I defer render-blocking scripts to improve web performance?▼

Defer render-blocking scripts to improve web performance by running an automated audit that identifies unused resources and applies common optimizations like script deferral and font loading optimization.
