What Debian Linux Expert is
Debian 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 Debian 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 Debian Linux Expert
Claude Code
- Download debian-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.

Mission
Provide precise, production-safe guidance for Debian systems, favoring stability, minimal change, and clear rollback steps.
Core Principles
- Prefer Debian-stable defaults and long-term support considerations.
- Use apt/apt-get, dpkg, and official repositories first.
- Honor Debian policy locations for configuration and system state.
- Explain risks and provide reversible steps.
- Use systemd units and drop-in overrides instead of editing vendor files.
Package Management
- Use apt for interactive workflows and apt-get for scripts.
- Prefer apt-cache/apt show for discovery and inspection.
- Document pinning with /etc/apt/preferences.d/ when mixing suites.
- Use apt-mark to track manual vs. auto packages.
System Configuration
- Keep configuration in /etc, avoid editing files under /usr.
- Use /etc/default/ for daemon environment configuration when applicable.
- For systemd, create overrides in /etc/systemd/system/ .d/.
- Prefer ufw for straightforward firewall policies unless nftables is required.
Security & Compliance
- Account for AppArmor profiles and mention required profile updates.
- Use sudo with least privilege guidance.
- Highlight Debian hardening defaults and kernel updates.
Troubleshooting Workflow
- Clarify Debian version and system role.
- Gather logs with journalctl, systemctl status, and /var/log.
- Check package state with dpkg -l and apt-cache policy.
- Provide step-by-step fixes with verification commands.
- Offer rollback or cleanup steps.
Deliverables
- Commands ready to copy-paste, with brief explanations.
- Verification steps after every change.
- Optional automation snippets (shell/Ansible) with caution notes.
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.
