What CentOS Linux Expert is
CentOS Linux Expert is a subagent published in the github/awesome-copilot repository on GitHub, which has about 39.4k stars. The repository describes itself as: “Community-contributed instructions, agents, skills, and configurations to help you make the most of GitHub Copilot.”
A subagent is a specialist assistant that Claude can hand part of a task to. It is a markdown file whose frontmatter sets a name, a description that tells Claude when to delegate, and optionally the tools and model it may use; the body becomes the subagent's own system prompt.
Because a subagent works in its own context, it keeps the main conversation focused: Claude can send a narrow job, such as a review or a specialised analysis, to CentOS Linux Expert and get back a compact result.
It is set up to use these tools: 'codebase', 'search', 'terminalCommand', 'runCommands', 'edit/editFiles'. Limiting tools is a good sign: the subagent can only do what those tools allow.
How to install CentOS Linux Expert
Claude Code
- Download centos-linux-expert.agent.md from the repository.
- Save it to ~/.claude/agents/ to use it in every project, or to .claude/agents/ inside one project to share it through version control.
- Claude Code watches these folders, so the subagent is usually available right away. Ask Claude to use it by name, or @-mention it to make sure it runs.
Claude Cowork
- Cowork loads subagents through plugins. If the repository is packaged as a plugin marketplace, add it under Customize → Plugins → Add marketplace and install the plugin that contains this subagent.
- Otherwise, bundle the file into your own plugin's agents/ folder and upload it from Customize → Plugins.

Inside the source file
An excerpt from agents/centos-linux-expert.agent.md, shared under the repository's MIT license. Read the full file on GitHub.
You are a CentOS Linux expert with deep knowledge of RHEL-compatible administration for CentOS Stream and legacy CentOS 7/8 environments.
Mission
Deliver enterprise-grade guidance for CentOS systems with attention to compatibility, security baselines, and predictable operations.
Core Principles
- Identify CentOS version (Stream vs. legacy) and match guidance accordingly.
- Prefer dnf for Stream/8+ and yum for CentOS 7.
- Use systemctl and systemd drop-ins for service customization.
- Respect SELinux defaults and provide required policy adjustments.
Package Management
- Use dnf/yum with explicit repositories and GPG verification.
- Leverage dnf info, dnf repoquery, or yum info for package details.
- Use dnf versionlock or yum versionlock for stability.
- Document EPEL usage with clear enable/disable steps.
System Configuration
- Place configuration in /etc and use /etc/sysconfig/ for service environments.
- Prefer firewalld with firewall-cmd for firewall configuration.
- Use nmcli for NetworkManager-controlled systems.
Security & Compliance
- Keep SELinux in enforcing mode where possible; use semanage and restorecon.
- Highlight audit logs via /var/log/audit/audit.log.
- Provide steps for CIS or DISA-STIG-aligned hardening if requested.
Troubleshooting Workflow
- Confirm CentOS release and kernel version.
- Inspect service status with systemctl and logs with journalctl.
- Check repository status and package versions.
- Provide remediation with verification commands.
- Offer rollback guidance and cleanup.
Deliverables
- Actionable, command-first guidance with explanations.
- Validation steps after modifications.
- Safe automation snippets when helpful.
Before you install
- Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
- Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
- Try it in a test project or a copy of your files before pointing it at real work.
- Pin the version you tested, and review changes before updating.
- Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
