 # Sysadmin Health Check Skill
 
 Performs a comprehensive health check on the local Arch Linux workstation.
 
+## Quick Command
+
+```bash
+~/.claude/skills/sysadmin-health/scripts/health-check.sh
+```
+
+Or run individual checks:
+
+```bash
+# Resources
+df -h / /home
+free -h
+uptime
+
+# Packages
+checkupdates | wc -l
+yay -Qua | wc -l
+pacman -Qtdq | wc -l
+
+# Services
+systemctl --failed
+systemctl --user --failed
+
+# Logs
+journalctl -p err --since "24 hours ago" -n 10
+```
+
 ## Checks Performed
 
-### System Resources
-- Disk usage (`df -h`)
-- Memory usage (`free -h`)
-- Swap usage
-- CPU load (`uptime`)
-- Top processes by resource usage
-
-### Package Status
-- Pending pacman updates (`checkupdates`)
-- AUR updates available (`yay -Qua`)
-- Orphaned packages (`pacman -Qtdq`)
-- Package cache size (`du -sh /var/cache/pacman/pkg`)
-
-### Service Status
-- Failed systemd services (`systemctl --failed`)
-- Key services status (NetworkManager, sshd, etc.)
-
-### User Timers (Claude Automation)
-- Active user timers (`systemctl --user list-timers`)
-- Failed user services (`systemctl --user --failed`)
-- Recent timer runs (`journalctl --user -u k8s-agent-health-check --since "24 hours ago" -n 5`)
-
-### Security
-- Recent failed login attempts (`journalctl -u sshd --since "24 hours ago" | grep -i failed`)
-- Last logins (`last -n 5`)
-
-### Logs
-- Recent errors in journal (`journalctl -p err --since "24 hours ago" -n 20`)
+| Category | Checks |
+|----------|--------|
+| **Resources** | Disk, memory, swap, CPU load |
+| **Packages** | Pacman updates, AUR updates, orphans |
+| **Services** | Failed systemd services (system + user) |
+| **Security** | Recent logins, failed SSH attempts |
+| **Logs** | Recent errors in journal |
 
 ## Output Format
 
-Report as structured summary with:
-- Overall health status (healthy/warning/critical)
-- Issues found (if any)
-- Recommended actions
+Report as structured summary:
+- **Overall health**: healthy/warning/critical
+- **Resource usage**: disk %, memory %
+- **Pending updates**: count
+- **Failed services**: list
+- **Issues found**: with recommendations
+
+## Thresholds
+
+| Metric | Warning | Critical |
+|--------|---------|----------|
+| Disk usage | >80% | >95% |
+| Memory usage | >80% | >95% |
+| Pending updates | >20 | >50 |
+| Failed services | any | any critical |
