"""Suspicious output evaluator
Detects responses that look like system output rather than
natural language, which may indicate the model could be manipulated into
executing commands or revealing information related to the host system.
This does't however necessarily designate a vulnerability.
TODO: Discuss this further and decide if these should be added to the vulnerability detection.
