eng-runbook

A skill for producing a single-page engineering runbook, a practical guide for operating and fixing a software service.

In plain words
What is it for?
Use it to document deployments, rollbacks, key rotation, alert responses, dependencies, on-call coverage, and incident handling.
Why use it?
It puts service details, alerts, dashboards, procedures, on-call contacts, and incident steps in one place when engineers need them quickly.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

eng-runbook scanned grade A with 0 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 3d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

100% identical to eng-runbook — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Engineering Runbook Skill

Produce a single-page engineering runbook.

Workflow

  1. Read DESIGN.md.
  2. Identify the service from the brief.
  3. Layout:
    • Header: service name, owner team, severity tier, version.
    • Service summary paragraph + dependency list.
    • Alerts table: alert name / severity / what it means / first response.
    • Dashboards & links list.
    • Common procedures block (3–4) with code blocks (deploy, rollback, rotate keys).
    • On-call rotation table (week / primary / secondary / backup).
    • Incident response checklist (5 numbered steps).
  4. One inline <style>, semantic HTML, monospace for code blocks.

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
