Web Vitals Optimizer

This skill focuses on the specific metrics that Google uses to measure user experience and search ranking.

Instructions

1. Audit the 3 core metrics: LCP, FID (or INP), and CLS.
2. Optimize image loading using modern formats and srcset.
3. Eliminate render-blocking resources in the critical path.
4. Minimize main-thread work to improve interactivity.
5. Use performance monitoring tools to track improvements over time.

Examples

• "Improve the CLS score of this page by pre-sizing image containers."
• "Optimize the First Input Delay (FID) by reducing initial JS execution."
