MEDIUM W013: Attempt to modify system services in skill instructions.

• Attempt to modify system services in skill instructions detected (high risk: 1.00). The skill includes explicit, system-altering commands (adduser/usermod, editing /etc/ssh/sshd_config, /etc/pam.d, /etc/audit/rules.d, chmod on sensitive files, installing packages, systemctl restart/enable, firewall changes) that create users and modify files/services—actions that require sudo and change the machine state.
