2 findings: 1 critical severity, 1 high severity. Installing this skill is not recommended: please review these findings carefully if you do intend to do so.
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 contains explicit, actionable proof-of-concept prompts and probes aimed at extracting system prompts, API keys, and cross-tenant data — i.e., clear instructions for data exfiltration and credential theft.
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
The document includes explicit PoC payloads and success_patterns that instruct testers to prompt the model to repeat system prompts or continue an API-key-like string (e.g., "sk-..."), which requires the LLM to output secret values verbatim.
