How to use the CentOS Linux Triage agent skill
Updated · written with AI from the project's own documentation and checked against our catalogue data
The CentOS Linux Triage skill is a set of instructions that makes an AI agent troubleshoot CentOS and RHEL-compatible systems the way a Linux administrator would. This guide explains what the skill does, how to install it, how to ask for help so it triggers, and what to check before running any command it suggests. By the end you will be able to get a structured triage plan for a failing service, package or firewall problem, with a way to verify and undo each change.
CentOS Linux Triagegithub/awesome-copilot · MIT Download the skill Quick start
- 1Download the ZIP. Download the skill ZIP from this page and unzip it. It contains SKILL.md.
- 2Choose a location. Place the folder in ~/.claude/skills/ for personal use, in a project's .claude/skills/ folder, or upload the ZIP under Settings → Capabilities → Skills in the Claude apps.
- 3Describe your problem. Write the symptom in plain language, with your CentOS version if known and any constraints such as a live server.
- 4Review the triage steps. Read the numbered triage steps and confirm the release and environment the agent assumed.
- 5Run remediation and validation. Run one command block at a time, and run the validation commands after each change.
- 6Keep the rollback ready. Save the rollback or cleanup steps before making changes so you can undo them if needed.
What the CentOS Linux Triage skill makes the agent do
Once the skill is installed, the agent answers CentOS troubleshooting questions as a Linux administrator would. It first confirms the CentOS release (Stream or legacy) and the environment assumptions, then works through numbered triage steps using systemctl, journalctl, dnf/yum and logs.
After triage, the agent gives remediation steps as copy-paste-ready commands, followed by validation commands after each major change. Where relevant it checks SELinux and firewalld, and it ends with rollback or cleanup steps.
- Confirms CentOS release and environment before diagnosing
- Numbered triage steps using systemctl, journalctl, dnf/yum and logs
- Copy-paste-ready remediation commands
- Verification commands after each major change
- SELinux and firewalld considerations where relevant
- Rollback or cleanup steps
How to install the CentOS Linux Triage skill
Download the ZIP file for the skill from this page and unzip it. The skill is a folder containing a file named SKILL.md. Place the folder in one of these locations:
- Personal skills: ~/.claude/skills/ (available across your projects)
- Project skills: the .claude/skills/ folder inside a specific project
- Claude apps: upload the ZIP under Settings → Capabilities → Skills
How to trigger the skill with natural requests
You do not need a special command. Describe your CentOS problem in plain language, and include the release if you know it, the symptom, and any limits such as 'do not restart the database'. The skill's inputs are an optional CentOS version, a problem summary, and optional constraints, so including those details helps the agent give a more accurate plan.
- Say which CentOS version you run, or that you are unsure
- Describe the symptom and any error message you see
- State constraints, for example that the server is live or that a reboot is not allowed
Examples of requests and what to expect
A useful request names the service or package and the symptom. The agent should respond with a summary, numbered triage steps, remediation commands, validation commands and a rollback section. Read each command before running it, and run validation after each change rather than at the end.
- 'On CentOS Stream 9, nginx fails to start after a config change. Give me a triage plan.'
- 'dnf install fails with a repository error on our legacy CentOS 7 box. Help me find the cause.'
- 'Port 8080 is open on the server but clients cannot connect. Check firewalld and SELinux.'
systemctl status nginx
journalctl -u nginx --since "1 hour ago"What the skill needs and how it runs
The skill lists no requirements, does not run scripts, and does not use the network. It produces commands for you to run on your system. The agent cannot verify what happens on your server unless you paste the output back into the conversation.
Safety notes before you run any command
The skill produces commands to run, and a wrong command on a live system can cause outages or data loss. Review production changes with a colleague first, and take a backup or snapshot where possible. Use the rollback steps the agent gives you, and check that each validation command returns the result you expect.
The skill is tuned for CentOS and RHEL-compatible tooling. On other distributions, paths and tools such as firewalld and SELinux can differ. It also focuses on general fixes, not forensic handling, so do not rely on it to preserve evidence after a security incident.
- Do not apply commands to production servers without review
- Check that the distribution is CentOS or RHEL-compatible
- Use the verification and rollback steps for every change
- Do not use it as a forensic or incident-response procedure
Tips for getting better triage results
Give the agent the exact error text and the output of a status command rather than a paraphrase. Ask it to confirm the release first if you are unsure. Ask for one change at a time so that each validation and rollback step stays clear.
- Paste exact error messages and log lines
- Ask for one change at a time
- Ask for the rollback step before you start, not after something breaks
What people use it for
- Diagnosing a systemd service that fails to start after a configuration change
- Working out why dnf or yum cannot install or update packages on a CentOS server
- Checking whether firewalld or SELinux is blocking a service that otherwise looks healthy
- Building a repeatable troubleshooting checklist for a team that maintains CentOS or RHEL-compatible servers
Frequently asked questions
How do I install the CentOS Linux Triage skill?
Download the ZIP from this page and unzip it so you have a folder containing SKILL.md. Put it in ~/.claude/skills/ for personal use or in a project's .claude/skills/ folder, or upload the ZIP in the Claude apps under Settings → Capabilities → Skills.
Does the centos-linux-triage skill require anything else?
The skill lists no requirements. It does not run scripts and does not use the network, so it works by producing commands for you to run on your own system.
Is the CentOS Linux Triage skill free?
The skill is published under the MIT licence on github/awesome-copilot. The source does not state pricing, so check the listing on this page for any cost details.
Can I use this skill on Ubuntu or Debian?
It is tuned for CentOS and RHEL-compatible tooling. Other distributions can differ in package managers, firewall and SELinux paths, so the commands may not fit those systems without adjustment.
Will the skill fix my server automatically?
No. The skill writes commands for you to review and run. It does not change your system by itself, so you stay in control of every change.
Is this skill suitable for a security incident?
No. It focuses on general fixes rather than evidence preservation, so a security incident needs dedicated forensic handling.

Our verdict
This skill suits system administrators and developers who run CentOS or RHEL-compatible servers and want a structured triage checklist with verification and rollback for each change. It is a poor fit for unreviewed production changes, other Linux distributions, or security incidents that need forensic handling, where a dedicated process is safer.
