What problem does it solve?
Diagnoses and fixes UI performance across loading speed, rendering, animations, images, and bundle size. Use when the user mentions slow, laggy, janky, performance, bundle size, load time, or wants a faster, smoother experience.
Core Features & Use Cases
- Assess Performance: Measure Core Web Vitals (LCP, FID/INP, CLS), load times, bundle size, runtime performance, and network requests.
- Optimization Strategy: Propose and execute end-to-end improvements across loading, rendering, animation, fonts, and APIs to deliver faster, smoother experiences.
- Use Case: Imagine a web app with a 3-second TTI; apply the skill to identify bottlenecks and implement changes that reduce load times and improve interactivity.
Quick Start
Run the optimize skill to diagnose a slow UI by measuring Core Web Vitals, bundle size, and runtime performance, then apply targeted fixes.
