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.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Self-Hosted GitHub Actions Runner Deploy and manage self-hosted GitHub Actions runners — the machines that execute CI/CD workflow jobs. Self-hosted runners give you control over hardware, OS, and toolchain, at the cost of requiring you to maintain the environment. ## When to Use | Trigger | What to do | |---------|------------| | "Set up CI for my project", "deploy a self-hosted runner for [repo/org]" | Read [deployment](references/deployment.md) — choose systemd, Docker, or ARC | | "Runner won't register / keeps failing", "runner gets 404", "registration token expired" | Read [management](references/management.md) — ACCESS_TOKEN vs RUNNER_TOKEN, groups | | "How to scale runners automatically", "auto-scale runners", "too many queued jobs" | Read [scaling](references/scaling.md) — ARC, Scale Set Client, ephemeral | | "Secure my self-hosted runners", "hardening runners", "runner security", "public repo risk" | Read [security](references/security.md) — public repo risks, ephemeral, JIT, groups | | "Make a custom runner image", "build a runner Dockerfile", "custom runner with Python" | Read [custom-images](references/custom-images.md) — Dockerfile, ARC container modes | …

How to install
mdr add magnus919/agent-skills/github-runner@sha256:a396248eb0fc622bThe line at the top of this page pins the label v1.0.2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
