Use when the user asks to "run housekeeping", "housekeeping report", "run a health check on ", or "do routine…

Run a heinzel security audit on a server — SSH hardening (password auth, weak algos, root login), firewall, user account hygiene, listening services, kernel hardening (ASLR, IP forwarding), file permissions, SUID/SGID audit, fail2ban. Use when the user asks for a "security audit", "security review", "hardening check"…
