```

## Action Combinations for Complex Tasks

    { "action": "execute_command", "command": "whoami /all" },
    { "action": "write_file", "file_path": "C:\\temp\\assessment_report.txt", "content": "Report content..." }
]
```

## Best Practices

1. **Always Check Success**
   - Verify `success: true` in response
   - Handle errors appropriately

2. **Use Appropriate Timeouts**
   - Quick operations: 10-30s
   - File scans: 60-120s
   - Network operations: 30-60s

3. **Security Considerations**
   - Don't write sensitive data to world-readable paths
   - Clear temp files after use
   - Log all operations for audit trail

4. **Error Handling**
   ```json
   {
       "success": true,
       "result": "<operation result>"
   }
   ```
   Or on failure:
   ```json
   {
       "success": false,
       "error": "error message"
   }
   ```

## Common Error Codes

| Error | Cause | Solution |
|-------|-------|----------|
| "未知操作" | Invalid action name | Check available_actions |
| "Permission denied" | Insufficient privileges | Run with elevated permissions |
| "File not found" | Path doesn't exist | Verify path with path_exists |
| "Access denied" | Protected resource | Check file/directory permissions |
| "Command timeout" | Operation took too long | Increase timeout value |

## Nested Parameters

Some actions accept additional parameters in a `kwargs` object:
```json
{
    "action": "list_files",
    "kwargs": {
        "path": "C:\\temp",
        "recursive": false
    }
}
```

This format is automatically handled by the tool.
