marp-slides

marp-slides is a skill for Claude Code, Codex from Agent-Engineer-Master/skill-engineer. It costs 113 tokens per session (1,340 once invoked), scanned C, original, MIT.

A workflow for creating and editing MARP slide decks. MARP is a tool that turns Markdown text into presentations in formats such as PDF, HTML, and PowerPoint.

In plain words
What is it for?
Use it to create a presentation, convert an outline into slides, revise an existing deck, build a custom CSS theme, add charts and dashboard-style elements, or summarize a MARP file.
Why use it?
It gives slide work a defined mode—creation, editing, theme changes, conversion, or reading—so the deck’s content and visual treatment can be handled according to the request.

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 C, and why

marp-slides scanned grade C with 1 finding 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 4d 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.

Hidden instructionshighPrompt injection

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

MARP Slides

Startup

  1. Read references/learnings.md — summarize the 3 most relevant bullets for this task
  2. Detect mode from the request (see Mode Selector)

Mode Selector

Request signals Mode
"create", "build", "make slides", "new deck", "presentation" A: Create
"edit", "update", "change slide N", "revise", "fix" B: Edit
"theme only", "CSS only", "just the styles", "color palette" C: Theme
"convert from", "turn this into slides", "import", "use this outline" D: Convert
"summarize this deck", "what does this cover", "read this marp" E: Read

Mode A: Create

A1. Intake (ask all at once in a single message)

Present these 4 questions before generating anything:

  1. Topic + purpose — what is the deck about, and who is the audience?
  2. Slide count — how many slides? (if unsure, apply word-count heuristic from references/quality-rules.md)
  3. Theme — dark (default) or light? Describe a vibe or brand if relevant.
  4. Brand context — use existing brand colors/logo? (if yes, read your brand guidelines file)

Wait for reply before continuing.

Why: Generating before intent is locked is the #1 source of wasted cycles in deck authoring. The 4-question intake costs one round-trip and saves 3–5 regeneration loops.

A2. Theme + outline

  1. Select theme using signal-to-theme mapping table in references/themes.md
  2. Draft a slide-by-slide outline: slide title, one key idea, layout type, visual element planned
  3. Present 3 layout direction options (e.g. minimal / data-heavy / editorial) — not full decks, just 3-slide skeleton previews as markdown
  4. Wait for user to approve direction or request changes before generating the full deck

A3. Generate

  1. Read references/components.md for SVG chart and component patterns
  2. Read references/layout-patterns.md for rotation rules and composition guidelines
  3. Read 2–3 examples from examples/ that most closely match the approved style
  4. Generate the full .md MARP file

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.
