### Custom Analysis Scripts
```javascript
// scripts/analyze-performance.js
const { exec } = require('child_process');
const fs = require('fs');

async function analyzePerformance() {
  // Run bottleneck detection
  const bottlenecks = await runCommand(
    'npx claude-flow bottleneck detect --format json'
  );

  // Generate performance report
  const report = await runCommand(
    'npx claude-flow analysis performance-report --format json'
  );

  // Analyze results
  const analysis = {
    bottlenecks: JSON.parse(bottlenecks),
    performance: JSON.parse(report),
    timestamp: new Date().toISOString()
  };

  // Save combined analysis
  fs.writeFileSync(
    'analysis/combined-report.json',
    JSON.stringify(analysis, null, 2)
  );

  // Generate alerts if needed
  if (analysis.bottlenecks.critical.length > 0) {
    console.error('CRITICAL: Performance bottlenecks detected!');
    process.exit(1);
  }
}

function runCommand(cmd) {
  return new Promise((resolve, reject) => {
    exec(cmd, (error, stdout, stderr) => {
      if (error) reject(error);
      else resolve(stdout);
    });
  });
}

analyzePerformance().catch(console.error);
```

## Best Practices

### 1. Regular Analysis

- Higher for development (25-30%)
- Adjust based on requirements

### 3. Fix Strategy
- Always review before applying --fix
- Test fixes in development first
- Apply fixes incrementally
- Monitor impact after changes

### 4. Report Integration
- Include in documentation
- Share with team regularly
- Track improvements over time
- Use for capacity planning

### 5. Continuous Optimization
- Learn from each analysis
- Build performance budgets
- Establish baselines
- Set improvement goals

## Troubleshooting
