# Optimize Skill

## Overview

The optimize skill provides comprehensive on-demand performance and optimization analysis for your codebase. It identifies bottlenecks, slow builds, large bundles, inefficient code patterns, and opportunities for performance improvements across all supported technology stacks.

**When to Use**:
- Performance issues and slow response times
- Large bundle sizes and slow page loads
- Long build and compile times
- High memory usage
- Database query optimization
- API endpoint performance tuning
- CI/CD pipeline optimization

**Technology Coverage**:
- React/TypeScript/JavaScript (Vite, Webpack, Rollup)
- Go applications (build time, runtime performance)
- Rust projects (compile time, binary size)
- Python codebases (runtime optimization)
- Full-stack applications
- Database queries (SQL, ORM)

## Optimization Categories

### 1. Build Performance

**What Gets Analyzed**:
- Build duration and bottlenecks
- Dependency resolution time
- TypeScript compilation speed
- Asset processing (images, fonts)
- Code splitting effectiveness
- Cache utilization

**Common Issues**:
- Unnecessary re-builds of unchanged code
- Large dependency trees
- Inefficient TypeScript configuration
- Missing build caching
- Redundant asset processing

**Optimization Targets**:
- Reduce build time by 30-50%
- Enable incremental builds
- Optimize dependency resolution
- Improve cache hit rates

### 2. Bundle Size

**What Gets Measured**:
- Total bundle size (uncompressed/gzipped)
- Individual chunk sizes
- Duplicate dependencies
- Tree-shaking effectiveness
- Unused code in bundles
- Third-party library sizes

**Bundle Analysis**:
```
Bundle Size Breakdown:
├── vendor.js: 847 KB (312 KB gzipped)
│   ├── react-dom: 142 KB
│   ├── lodash: 71 KB (should use lodash-es)
│   ├── moment: 67 KB (consider date-fns)
│   └── ...
├── main.js: 234 KB (89 KB gzipped)
└── [lazy chunks]: 156 KB total
```

**Optimization Goals**:
- Keep initial bundle under 200 KB (gzipped)
- Lazy load
