How does this skill help identify performance bottlenecks?

The skill provides a systematic 'Measure First' methodology, categorizing issues into CPU, Memory, I/O, Network, or Database bottlenecks to ensure optimizations are based on data rather than intuition.

Does it support backend profiling for specific languages?

It provides specific profiling commands and flame graph generation techniques for popular runtimes including Node.js, Python (py-spy), and Go (pprof).

What frontend metrics does this skill focus on?

It focuses on Google's Core Web Vitals, specifically Largest Contentful Paint (LCP), Interaction to Next Paint (INP), and Cumulative Layout Shift (CLS), offering actionable fixes for each.

Can Claude help with database query optimization using this skill?

Yes, it includes detailed patterns for using EXPLAIN ANALYZE, identifying N+1 query patterns, and implementing composite or partial indexes to significantly reduce query time.
