Md To PDF

What it does

When your agent uses it

• : convert markdown to pdf
• Make a pdf from this md
• Export markdown as pdf
• Pdf from markdown with equations

Example prompts

• “convert markdown to pdf”
• “make a pdf from this md”
• “export markdown as pdf”
• “/md-to-pdf”

Requirements

• Python 3
• Node.js
• A Bash shell

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

1. 1Determine the input file path (uploaded file or user-specified path)
2. 2Run setup check if this is the first use in the session
3. 3Execute conversion
4. 4Present the output file to the user

What it can do on your machine

Read from SKILL.md and the folder at commit 4594fb7. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Ships 3 files in scripts/ (JavaScript, Python and Shell), which the agent can run.

  Shell commands in SKILL.md call:

  • python3
  • bash
  • npm
  • playwright
  • apt
  • pip

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md. Its commands use npm and pip, which can reach the network depending on how they are called.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Md To PDF loads about 2.4k tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 579 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~61

When it runs · the whole SKILL.md, loaded when a task matches

~2.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

     ├─ 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
