Slow UI performance makes apps feel broken, causing delays, jank during interactions, and bloated downloads that hurt retention and usability.
Use the optimize skill to assess your current Core Web Vitals and identify the biggest bottleneck driving slow loads or janky interactions, then apply targeted fixes and verify the improvement with before/after measurements.

Fix UI performance issues by diagnosing Core Web Vitals and runtime bottlenecks, then applying targeted optimizations like code splitting, asset compression, and GPU-friendly animations to make your UI feel instant.
Poor Core Web Vitals and bloated bundle size are caused by expensive rendering, oversized images and fonts, excessive JavaScript execution, and inefficient CSS strategies that delay loading and cause layout shift.
Profile rendering bottlenecks by measuring load timing, runtime behavior, and network waterfall patterns using real-device monitoring tools to identify expensive layout, paint, and composite operations.
Yes, this optimization approach works for images, fonts, and CSS by applying best practices for asset reduction, code splitting, and layout-thrashing avoidance to improve real-world user experience.
Prevent UI performance regressions by comparing before and after metrics, validating improvements on real devices and slow connections, and continuously monitoring Core Web Vitals to catch new bottlenecks.
