Diagnose and resolve CentOS issues

centos-linux-triage is an agent skill from the github/awesome-copilot collection for diagnosing and resolving problems on CentOS Linux servers. It works with RHEL-compatible commands and is aware of SELinux and firewalld, which often cause problems that look like application faults. The skill first confirms which CentOS release is in use, Stream or a legacy version, and what the environment assumes, because the right commands and package sources depend on it. It then gives triage steps built on systemctl for services, journalctl and log inspection for messages, and dnf or yum for packages. The remediation steps are written as copy-paste commands, and each major change is followed by verification commands that show whether it worked. The skill also addresses SELinux and firewalld considerations where relevant, and it always provides rollback or cleanup steps so a fix can be undone. The skill is useful for system administrators who need a structured way to work through an incident, and for people who are less familiar with Red Hat-style systems. Commands that change a production server should be run only after the administrator has read them, and a backup or snapshot should be taken before significant changes. The skill is installed with the skills CLI from the github/awesome-copilot repository. Its skills.sh page showed about 8.7K installs and passing results from three security audits at the time of the scan.
