The Agent Skills Directory

[COMMAND_EXECUTION]: The skill contains multiple shell scripts designed for system administration tasks. These include establishing security baselines, configuring firewalls (UFW), hardening SSH, and setting system-wide security parameters via sysctl. All commands are standard for Linux hardening and monitoring (e.g., systemctl, ss, ufw, chmod, usermod).
[EXTERNAL_DOWNLOADS]: The hardening implementation scripts facilitate the installation of well-known and trusted security packages such as fail2ban, lynis, rkhunter, and auditd from official system package repositories using the distribution's native package manager (apt-get).
[SAFE]: The skill's operations are transparent, well-documented, and align strictly with its stated purpose of improving server security posture. It incorporates validation phases and maintenance schedules consistent with industry-standard security frameworks like CIS, NIST, and PCI DSS.
