A converter that turns Markdown files into styled PDF documents, including diagrams, mathematical formulas, tables, and highlighted code.

Use it to export Markdown reports, technical documentation, or papers containing Mermaid diagrams, LaTeX or KaTeX equations, tables, and code blocks.

It removes the need to manually format these elements or assemble several separate tools when producing a polished PDF.

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 5.1	$0.00060	$0.02153
Opus 5	$0.00030	$0.01077
Sonnet 5	$0.00012	$0.00431
Haiku 4.5	$0.00006	$0.00215

Security

Grade A, and why

md-to-pdf 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 9d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/katex_render.js, scripts/md_to_pdf.py, scripts/setup.sh), 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 — 211 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Markdown to PDF Converter

Converts Markdown files to professionally styled PDFs with full rendering of Mermaid diagrams, LaTeX math (via KaTeX), tables, syntax-highlighted code blocks, and all standard Markdown features.

Architecture

Input .md file
     │
     ├─ Step 1: Extract ```mermaid blocks → render to SVG via mmdc (Mermaid CLI + Puppeteer)
     │          Replace mermaid code blocks with inline <svg> in the markdown source
     │
     ├─ Step 2: pandoc converts modified markdown → standalone HTML5
     │          (--katex flag preserves raw LaTeX in <span class="math ..."> elements)
     │
     ├─ Step 3: Node.js KaTeX server-side rendering
     │          Replaces math spans with fully rendered KaTeX HTML (no client-side JS needed)
     │
     ├─ Step 4: CSS injection
     │          KaTeX stylesheet (with local font paths) + professional document styles + optional custom CSS
     │
     └─ Step 5: Playwright (headless Chromium) prints final HTML → PDF
                 ↓
           Output .pdf file

What ships with it

7 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.
