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 | $0.00069 | $0.00382 |
| Opus 5.5 | $0.00028 | $0.00153 |
| Sonnet 5.5 | $0.00014 | $0.00076 |
| Haiku 4.5 | $0.00007 | $0.00038 |
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 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.
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.
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
- Read DESIGN.md.
- Identify the service from the brief.
- 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).
- One inline
<style>, semantic HTML, monospace for code blocks.

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.
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.
