Security audit

One Skill To Rule Them All

Security checks across malware telemetry and agentic risk

Overview

This is a security-review skill with dangerous examples, but they are clearly presented as threats to detect or remove rather than actions to perform.

Reasonable to install as an advisory security-review aid. Be aware that the skill includes realistic malicious examples, so do not copy or run those snippets, and treat any generated cleaned version or safety verdict as a starting point for manual review rather than a certification.
