Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00080 | $0.01845 |
| Opus 5.5 | $0.00032 | $0.00738 |
| Sonnet 5.5 | $0.00016 | $0.00369 |
| Haiku 4.5 | $0.00008 | $0.00185 |
Grade B, and why
github-runners-setup-skill scanned grade B with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

What I do
I turn a Linux box into a pool of GitHub Actions self-hosted runners for an
organization, one runner per subfolder of a chosen root (e.g.
~/GITHUB_RUNNERS/r1..rN), each as an auto-starting systemd service. I also
provide the workflow pattern that runs jobs on these runners only when one
is online and idle, falling back to ubuntu-latest otherwise.
Validated runbook (nus-cee org, Ubuntu 24.04, runners v2.337.0, 4 folders).
When to use me
- "Set up this machine as GitHub Actions runners" / "add local runners to my org"
- "Use my machine for CI when it's free, GitHub's otherwise"
- Adding more runner folders to an existing pool
Preconditions
- Linux x64, systemd,
ghCLI installed and authenticated - User is a member of the target org with rights to register runners
- Private repos (or public repos with fork-PR approvals enforced — self-hosted runners execute arbitrary workflow code from the repo)
Procedure
Defaults below: org ORG, runner root ~/GITHUB_RUNNERS, folders r1..rN,
host label prefix <hostname>. Ask the user for org + count + names once,
up front, with the question tool — then do not re-ask.
1. Scope check (GATED)
The registration API needs the admin:org scope. Check first:
gh auth status | grep -q "'admin:org'" || echo NEEDS_REFRESH
If refresh is needed, spawn it in a PTY, show the user the one-time code, and wait for their confirmation before continuing:
gh auth refresh -h github.com -s admin:org
2. Install runner bits (automated)
Download once, extract into the first folder, copy to the rest:
VER=$(gh api /repos/actions/runner/releases/latest --jq .tag_name | tr -d v)

( cd /tmp && sha256sum -c "actions-runner-linux-x64-$VER.tar.gz.sha256" )
mkdir -p ~/GITHUB_RUNNERS/r1
tar xzf /tmp/actions-runner-linux-x64-$VER.tar.gz -C ~/GITHUB_RUNNERS/r1
cd ~/GITHUB_RUNNERS

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

github-runners-setup-skill is a skill published in the GitHub repository darellchua2/opencode-config-template (6 stars, last pushed 28d ago), licensed Apache-2.0. It adds 80 tokens to every session and 1,845 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it B with 2 findings (asks for root, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-20.
