Designed for quick integration with shell tools like `grep`, `ping`, `jq`, etc.
⚠️ Warning:
Be cautious when using ShellAction with untrusted user input. Since it uses
`shell=True`, unsanitized input can lead to command injection vulnerabilities.
Avoid passing raw user input directly unless the template or use case is secure.
⚠️ Security Warning:
By default, ShellAction uses `shell=True`, which can be dangerous with unsanitized input.
To mitigate this, set `safe_mode=True` to use `shell=False` with `shlex.split()`.
Features:
- Automatically handles input parsing (str/bytes)
- `safe_mode=True` disables shell interpretation and runs with `shell=False`
- Captures stdout and stderr from shell execution
- Raises on non-zero exit codes with stderr as the error
- Result is returned as trimmed stdout string
