github-runner

72 / 100 · Review before installing

Check before installing. Some of what it can do is expected: a devops skill usually runs commands, installs tools and uses cloud credentials.

By magnus919/agent-skills (GitHub) · devops · 172 stars · scanned at commit da4ce5c

Deploy, manage, and troubleshoot self-hosted GitHub Actions runners. Covers systemd service, Docker containers, Kubernetes (Actions Runner Controller), and the Scale Set Client. Use when setting up a CI runner, debugging registration failures, designing autoscaling, or hardening runner security. Do not use this skill for unrelated requests; route to the nearest named specialist.

Works with any agent that supports SKILL.md skills.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'github-runner' ] || [ -L ~/.agents/skills/'github-runner' ]; then echo 'A skill folder named github-runner already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/magnus919/agent-skills' "$d" && git -C "$d" checkout --quiet 'da4ce5c6823cce6da80f4e09c84998a4928402c1' -- 'github-runner' && mkdir -p ~/.agents/skills && cp -R "$d"/'github-runner' ~/.agents/skills/'github-runner' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'github-runner' ~/.claude/skills/'github-runner' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
