The Agent Skills Directory

[PRIVILEGE_ESCALATION]: The skill performs operations that require administrative access to alter system-wide network configurations and services.
It modifies system files such as /etc/sysctl.conf to enable IP forwarding.
It performs software installation using apt and manages system services using systemctl to enable the VPN on boot.
[COMMAND_EXECUTION]: The skill utilizes shell scripts and the Python subprocess module to execute low-level networking and encryption utilities.
It invokes system tools including wg, wg-quick, openvpn, ip, and iptables to manage tunnels and routing.
[CREDENTIALS_UNSAFE]: The Python client implementation handles sensitive cryptographic material insecurely by writing it to a predictable, shared location.
It writes WireGuard and OpenVPN configuration files containing private keys to /tmp/wg0.conf and /tmp/client.ovpn. On many systems, the /tmp directory is world-readable, potentially exposing these credentials to other local users.
[PERSISTENCE]: The skill implements a persistence mechanism to ensure the VPN tunnel remains active across system restarts.
It uses systemctl enable to register the VPN as a persistent system service.
[EXTERNAL_DOWNLOADS]: The Python implementation relies on the wgconfig library, which is an external dependency not included in the standard Python library.
