About Performance Optimization
From Addy Osmani's agent-skills pack.
Keeps the agent from guessing. It profiles before touching anything, finds the actual bottleneck (slow Core Web Vitals, N+1 queries, a regression), fixes it, and measures again. Useful when a vibe-coded app starts feeling slow and you want evidence, not premature optimization.
