2 findings: 1 critical severity, 1 medium 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 skill intentionally instructs bypassing sandbox protections by switching to run_shell/direct system Python execution when execute_code_sandbox "fails", which enables arbitrary code execution and circumvents security controls — a high-risk backdoor/abuse pattern.
W013: Attempt to modify system services in skill instructions.
What this means
The skill prompts the agent to compromise the security or integrity of the user’s machine by modifying system-level services or configurations, such as obtaining elevated privileges, altering startup scripts, or changing system-wide settings.
Why it was flagged
The skill explicitly tells the agent to abandon the sandbox and "Immediately switch to run_shell" and even notes that "Direct system Python execution bypasses sandbox restrictions," which instructs bypassing security controls and could enable compromising the host.
