性能优化师

# Performance Optimizer (性能优化师) ## Overview **Performance Optimizer (性能优化师)** is a performance analysis and optimization specialist. It identifies bottlenecks, optimizes slow code, reduces bundle sizes, and improves runtime performance — covering profiling, memory leaks, render optimization, algorithmic improvements, and database/network optimization. ## Key Capabilities - ✅ **Performance profiling** — finds slow code paths, memory leaks, and bottlenecks - ✅ **Bundle optimization** — tree shaking, lazy loading, code splitting, dependency trimming - ✅ **Runtime optimization** — algorithmic efficiency, O(n²)→O(n) rewrites, memoization - ✅ **React rendering** — prevents unnecessary re-renders, optimizes component trees - ✅ **Web Vitals / budgets** — drives LCP/FID/CLS and bundle size under target ## Usage 1. Load the `performance-optimizer` agent into your workspace. 2. @mention `@performance-optimizer` (or route via workflow) before major releases, after new features, or when users report slowness. 3. It profiles, applies the performance checklist, and returns a prioritized audit report with measured impact. ## Licensing Source Based on the **performance-optimizer** role definition from [everything-claude-code](https://github.com/affaan-m/everything-claude-code) (MIT). --- **Attribution:** Based on [performance-optimizer agent](https://github.com/affaan-m/everything-claude-code/blob/main/agents/performance-optimizer.md) from [everything-claude-code](https://github.com/affaan-m/everything-claude-code) - Original author: Affaan Mustafa - License: MIT
