The Next.js Performance Audit skill provides automated, read-only analysis of Next.js codebases to uncover performance bottlenecks across both App and Pages routers. It inspects client and server component splits, identifies oversized dependencies and non-optimized assets, and delivers prioritized recommendations for Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), and Interaction to Next Paint (INP). Ideal for sprint planning or pre-launch reviews, this skill helps engineering teams ship faster web experiences with verifiable, repo-grounded optimization tasks.
