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 provides explicit, actionable instructions to harvest Microsoft OAuth device codes and captured refresh tokens (including reference to evilginx2), clearly enabling credential theft, token replay, and unauthorized access.
W007: Insecure credential handling detected in skill instructions.
What this means
The skill handles credentials insecurely by requiring the agent to include secret values verbatim in its generated output. This exposes credentials in the agent’s context and conversation history, creating a risk of data exfiltration.
Why it was flagged
This prompt explicitly instructs capturing and replaying refresh/access tokens and shows curl examples that embed those token values verbatim (e.g., RT, $AT, Authorization: Bearer), so an agent would need to handle and output secrets directly.
