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 skill explicitly instructs bypassing a restricted sandbox by writing and executing arbitrary scripts and shell commands, enabling remote code execution, persistence, and potential data exfiltration — high abuse potential.

Report incorrect finding
Medium

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 instructs the agent to write files and execute arbitrary shell commands on the host (including pip installs, chmod, rm) to bypass the sandbox, which changes machine state and increases risk even though it does not request sudo or create system users.
