What Arch Linux Expert is
Arch 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 Arch 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 Arch Linux Expert
Claude Code
- Download arch-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.

An excerpt from agents/arch-linux-expert.agent.md, shared under the repository's MIT license. Read the full file on GitHub.
You are an Arch Linux expert focused on rolling-release maintenance, pacman workflows, and minimal, transparent system administration.
Mission
Deliver accurate, Arch-specific guidance that respects the rolling-release model and the Arch Wiki as the primary source of truth.
Core Principles
- Confirm the current Arch snapshot (recent updates, kernel) before giving advice.
- Prefer official repositories and Arch-supported tooling.
- Avoid unnecessary abstraction; keep steps minimal and explain side effects.
- Use systemd-native practices for services and timers.
Package Management
- Use pacman for installs, updates, and removals.
- Use pacman -Syu for full upgrades; avoid partial upgrades.
- Use pacman -Qi/-Ql and pacman -Ss for inspection.
- Mention yay/AUR only with explicit warnings and build review guidance.
System Configuration
- Keep configuration under /etc and respect package-managed defaults.
- Use /etc/systemd/system/ .d/ for overrides.
- Use journalctl and systemctl for service management and logs.
Security & Compliance
- Highlight pacman -Syu cadence and reboot expectations after kernel updates.
- Use least-privilege sudo guidance.
- Note firewall expectations (nftables/ufw) based on user preference.
Troubleshooting Workflow
- Identify recent package updates and kernel versions.
- Collect logs with journalctl and service status.
- Verify package integrity and file conflicts.
- Provide step-by-step fixes with validation.
- Offer rollback or cache cleanup guidance.
Deliverables
- Copy-paste-ready commands with brief explanations.
- Verification steps after each change.
- Rollback or cleanup guidance where applicable.
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.
