Question 1

How does this skill improve my Next.js workflow?

Accepted Answer

It acts as an automated performance consultant that understands modern Next.js conventions. Instead of manual auditing, it provides direct code improvements for data fetching, asset delivery (next/image, next/font), and intelligent code-splitting.
