A solid troubleshooting companion for when your Arch system decides to break after a rolling update. It walks through systematic diagnostics using journalctl for service failures, pacman for dependency conflicts, and systemctl for daemon issues. The skill generates actual commands you can copy-paste rather than generic advice, covers the usual suspects like kernel module problems and systemd unit failures, and includes rollback steps for when fixes go sideways. Honestly, it's what you'd do manually anyway, but having the checklist saves you from forgetting to check obvious things like disk space or corrupted package databases when you're troubleshooting at 2am.
