performance-audit

This skill guides you through performing comprehensive performance audits on web applications to identify bottlenecks, optimization opportunities, and performance regressions. Use this when preparing for production deployments, investigating performance issues, or conducting periodic performance reviews.

Objective: Understand the application architecture, tech stack, and performance surface area.

Objective: Identify large dependencies, code splitting opportunities, and dead code.

Load PROACTIVELY when task involves optimizing speed, reducing bundle size, or improving responsiveness. Use when user says "make it faster", "reduce bundle size", "fix slow queries", "optimize rendering", or "check Core Web Vitals". Covers bundle analysis and tree-shaking, database query optimization (N+1, indexing), React rendering performance (re-renders, memoization), network waterfall optimization, memory leak detection, server-side performance, and Core Web Vitals (LCP, FID, CLS) improvement.
