A tool workflow for converting PDF files into Markdown while preserving document structure and LaTeX formulas. Markdown is plain text with formatting conventions commonly used in code repositories and documentation.

Use it to extract papers and other PDFs into Markdown, keep equations readable, and choose whether temporary conversion files are retained.

It makes technical or academic PDFs easier to search, edit, reuse, and process as text without losing mathematical notation.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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	$0.00045	$0.00490
Opus 5	$0.00023	$0.00245
Sonnet 5	$0.00009	$0.00098
Haiku 4.5	$0.00005	$0.00049

Security

Grade A, and why

marker 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 4d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/marker_to_markdown.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.

What it actually says

Marker PDF-to-Markdown Converter

Convert PDFs to Markdown while preserving LaTeX formulas and document structure. Uses the marker_single CLI from the marker-pdf package.

Dependencies

marker_single on PATH (pip install marker-pdf if missing)
Python 3.10+ (available in the task image)

Quick Start

from scripts.marker_to_markdown import pdf_to_markdown

markdown_text = pdf_to_markdown("paper.pdf")
print(markdown_text)

Python API

pdf_to_markdown(pdf_path, *, timeout=600, cleanup=True) -> str
- Runs marker_single --output_format markdown --disable_image_extraction
- cleanup=True: use a temp directory and delete after reading the Markdown
- cleanup=False: keep outputs in <pdf_stem>_marker/ next to the PDF
- Exceptions: FileNotFoundError if the PDF is missing, RuntimeError for marker failures, TimeoutError if it exceeds the timeout
Tips: bump timeout for large PDFs; set cleanup=False to inspect intermediate files

Command-Line Usage

# Basic conversion (prints markdown to stdout)
python scripts/marker_to_markdown.py paper.pdf

# Keep temporary files
python scripts/marker_to_markdown.py paper.pdf --keep-temp

# Custom timeout
python scripts/marker_to_markdown.py paper.pdf --timeout 600

Output Locations

cleanup=True: outputs stored in a temporary directory and removed automatically
cleanup=False: outputs saved to <pdf_stem>_marker/; markdown lives at <pdf_stem>_marker/<pdf_stem>/<pdf_stem>.md when present (otherwise the first .md file is used)

Troubleshooting

marker_single not found: install marker-pdf or ensure the CLI is on PATH
No Markdown output: re-run with --keep-temp/cleanup=False and check stdout/stderr saved in the output folder

Files

What ships with it

1 file 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.
