Important Notes:
- Security: Be cautious when executing commands, especially those constructed from user input, to prevent security vulnerabilities.
- Interactive Commands: Avoid commands that require interactive user input, as this can cause the tool to hang. Use non-interactive flags if available (e.g., npm init -y).
- Error Handling: Check the Stderr, Error, and Exit Code fields to determine if a command executed successfully.
