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 tells the agent to use run_shell to execute embedded Python that "bypasses the sandbox restrictions" and even suggests installing packages via pip and running arbitrary shell commands that can modify system state, so it encourages actions that can compromise the host.
