demo-runbook

demo-runbook is a skill for Claude Code, Codex from marchatton/agent-skills. It costs 65 tokens per session (1,983 once invoked), scanned A, original, MIT.

A package for running a live software demo and documenting it in a script and a single web page. It also explains the system design, including patterns such as RAG, evaluation, and observability.

In plain words
What is it for?
Use it to prepare what to show, what to click, technical explanations, caveats, and a respectful comparison with alternatives.
Why use it?
It keeps a demo focused, repeatable, and technically understandable for its audience.

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

demo-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 7d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/validate_inputs.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 — 190 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Demo Runbook

Create a demo package that is demo-first, user-empathy-led, and technically credible. Produce two deliverables every time: a demo script and a single-file HTML runbook.

When to use this skill

Use this skill when asked to create or refresh a demo (often a PoC demo) that:

  • Starts with an end-to-end live demo before explaining why, what, and how
  • Includes a competitive landscape comparison using April Dunford’s respectful approach framing
  • Includes technical architecture details, especially LLM patterns (RAG, evals, observability)
  • Produces both a talk track and a navigable runbook page

Example triggering requests:

  • “Help me create a PoC demo runbook and script for a live demo.”
  • “Make a demo-first talk track, then cover why/what/how and architecture.”
  • “Create a single HTML runbook with links, diagrams, and sections for tech stack.”
  • “Write a respectful competitive comparison and explain our approach.”

Outputs

Always produce both:

  1. Demo script as markdown (talk track + what to click + timings)
  2. Single-file HTML runbook (visual-first with custom CSS, navigable sections, Mermaid diagrams (flowchart + sequence), in-app hyperlinks, back-to-home navigation)

HTML runbook must:

  • Be single-file HTML (no build step required) with custom CSS styling (cards/callouts/layout), not a plain document.
  • Include Mermaid diagrams (at least one flowchart and one sequence diagram).
  • Include navigation between sections (hash router is fine) and “Back to Home” affordances.
  • Include an app links section with real links or TODO placeholders.

When returning outputs, format as:

  • === demo-script.md === then the markdown
  • === demo-runbook.html === then the full HTML

Input schema

Accept inputs in either bullet form or JSON. If any field is missing, insert a clear TODO placeholder rather than asking questions.

Minimum inputs to request are not required. Proceed with placeholders.

Core narrative

  • poc_name: Name of the PoC
  • tagline: One-line value statement
  • audience: Who is watching (and expected technical depth)
  • segment:
    • organisation: The organisation context (industry, size, geography, constraints)
    • buyer: Who buys / signs (budget owner, success metric, risk posture)
    • end_user: Who uses it day-to-day (workflow, pain, what “better” feels like)
  • job_to_be_done: What the user is trying to do
  • starting_feelings: How they feel at the start (rushed, uncertain, risk-averse, too many tabs)
  • desired_feelings: How the product changes that (confidence, clarity, speed, fewer guesses)
  • scenario: The demo scenario in plain English
  • success_outcome: What “done” looks like for the user
  • business_success_outcome: What success looks like for the business (be specific: $ impact or growth/adoption metric + timeframe)

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.
