The Agent Skills Directory

[COMMAND_EXECUTION]: The skill provides shell commands for installing software via apt, managing services with systemctl, and configuring networking with iptables and wg-quick. These operations are standard and necessary for setting up a VPN server.
[CREDENTIALS_UNSAFE]: No hardcoded credentials were found. The skill includes clear warnings against storing private keys in version control and demonstrates secure practices by using umask 077 and chmod 600 when generating or storing key material.
[EXTERNAL_DOWNLOADS]: The skill references installing the wireguard package through the standard system package manager (apt) and interacting with DuckDNS, a well-known dynamic DNS service, via curl. These are legitimate and safe operations for the stated purpose.
[PERSISTENCE]: The instructions include enabling the WireGuard service on boot using systemctl and setting up a cron job for dynamic DNS updates. These persistence mechanisms are standard requirements for maintaining a reliable remote access gateway.
[DYNAMIC_EXECUTION]: A Python snippet is provided that uses subprocess to generate WireGuard keys. This script generates configuration strings from the tool's output and does not execute untrusted or dynamically generated code.
