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 privileged, state-changing actions (dd on /dev/sda, mount/copy of the EFI partition, chipsec/flashrom firmware dumps, and remediation steps that reflash firmware or rebuild the ESP), which require elevated privileges and can modify or damage the host system.
