performance-profiling

Quick Review

Well-structured performance profiling skill with clear tables and workflow guidance. Provides actionable knowledge on Core Web Vitals, profiling workflows, bundle analysis, and common bottlenecks. The description is somewhat generic but adequate for invocation. Strong organization with concise overview and automated Lighthouse script. Moderate novelty—while it consolidates useful profiling principles and metrics, much of this is available in standard documentation. A CLI agent could perform basic profiling with web searches, but this skill meaningfully reduces token cost by providing structured decision tables, metric targets, and prioritized actions in a single reference.
