Critical

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 XSS exploitation playbook that instructs how to craft payloads, exfiltrate tokens/data to attacker-controlled collaborators, perform cache poisoning and CSRF chains, and use obfuscation/remote-eval techniques — indicating deliberate malicious intent and high abuse potential.
