A runbook generator that turns a YAML work plan into draft GitHub issues. It creates a parent tracking issue, grouped child workstream issues, sequential batches, phase gates, and a script for creating them.

Use it to validate a runbook specification, generate issue and summary files, and prepare an idempotent GitHub CLI script for later issue creation.

It organizes large projects into reviewable workstreams without publishing issues automatically.

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.

Model	Per session	Once invoked
Fable 5	$0.00058	$0.01176
Opus 5	$0.00029	$0.00588
Sonnet 5	$0.00012	$0.00235
Haiku 4.5	$0.00006	$0.00118

Security

Grade A, and why

gh-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 2d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/generate_runbook.py, scripts/validate_skill.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 110 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/gh-runbook — spec-driven runbook generator

Turn a PRD-phase spec into a parent tracking issue + N child workstream issues + an idempotent gh issue create script. Target repo: aram-devdocs/plumb.

Use /gh-issue afterwards to drive each child issue through the delivery lifecycle.

Usage

/gh-runbook docs/runbooks/phase-1-spec.yaml --dry-run
/gh-runbook docs/runbooks/phase-1-spec.yaml --output-dir .agents/runs/gh-runbook/phase-1/
/gh-runbook docs/runbooks/roadmap-spec.yaml --output-dir .agents/runs/gh-runbook/roadmap/

The underlying script:

python3 .agents/skills/gh-runbook/scripts/generate_runbook.py \
    docs/runbooks/phase-1-spec.yaml \
    --output-dir .agents/runs/gh-runbook/phase-1/ \
    --dry-run

Workflow

Read the spec YAML. Validate it against schemas/runbook-spec.json (via cargo xtask validate-runbooks if available, or via the generator's --validate-only mode).
Render the parent issue body from assets/parent-issue-template.md with all batches laid out as sub-sections.
Render one child issue body per child from assets/child-issue-template.md.
Emit manifest.json, summary.md, create-issues.sh in the output directory.
Review summary.md.
Only execute create-issues.sh after approval — it creates the real GitHub issues and updates the parent body with real issue numbers.

Spec schema

See references/spec-format.md for the full YAML grammar. A minimal skeleton:

What ships with it

5 files 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.
