E006: Malicious code pattern detected in skill scripts.

What this means

Detected high-risk code patterns in the skill content — including its prompts, tool definitions, and resources — such as data exfiltration, backdoors, remote code execution, credential theft, system compromise, supply chain attacks, and obfuscation techniques.

Why it was flagged

This document is an explicit offensive playbook guiding an attacker to discover and weaponize Node.js/Express weaknesses (prototype pollution, SSTI, child_process injection, LFI/environment exfiltration and OOB callbacks) to achieve RCE and steal secrets.
