Guardrail System

Security checks across malware telemetry and agentic risk

Overview

This skill is a small guardrail library whose sensitive-looking text is used as test and detection examples, not as hidden behavior.

This skill is reasonable to install if you want a simple local guardrail helper, but treat it as a lightweight example library: review and tune the regex patterns before relying on it for production security decisions.
