Performance Optimizer Skill

What problem does it solve?

Slow page loads, large assets, render-blocking resources, and poor Core Web Vitals that reduce conversions, search rankings, and user satisfaction are diagnosed and fixed with concrete, implementable optimizations.

Core Features & Use Cases

• Comprehensive Audits: Run Lighthouse CLI audits and extract FCP, LCP, CLS, TTI, and TBT insights.
• Asset Optimization: Identify and generate recommendations for images (srcset, WebP, compression), CSS (critical CSS, purge/minify), JavaScript (minify, code-splitting, defer/async), and fonts (subsetting, preload, font-display).
• Implementation Support: Provide minified outputs, HTML snippets for srcset/preload, build-tool configuration tips, and a verification plan with before/after metrics.
• Use Case: Improve a marketing landing page's LCP and TTI by optimizing hero images, splitting vendor bundles, and inlining critical CSS to reach Lighthouse performance targets.

Quick Start

Run a Lighthouse audit on the target site URL and return a prioritized optimization plan with expected impact estimates.
