## Common Patterns

### Logging

All scripts use consistent logging:
```bash
log "INFO" "Message"
log "WARNING" "Warning message"
log "ERROR" "Error message"
log "SUCCESS" "Success message"
```

### Error Handling

Standard error handling:
```bash
error_exit "Error message"  # Exits with code 1
warning "Warning message"   # Logs warning, continues
```

### Exit Codes

Standard exit codes:
- `0`: Success
- `1`: General error
- `2`: Invalid arguments
- `3`: Missing dependencies
