# Sysadmin Health Check Skill

Performs a comprehensive health check on the local Arch Linux workstation.

## Checks Performed

### System Resources

- 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`)

## Output Format
