markitdown

markitdown is a skill for Codex from GitHubxsy/agent-skills. It costs 206 tokens per session (1,775 once invoked), scanned A, original, Apache-2.0.

A document-conversion tool from Microsoft that turns files, images, and web pages into Markdown, a plain-text format with headings and lists. It supports formats including PDF, Word, PowerPoint, Excel, HTML, CSV, JSON, XML, EPUB, ZIP, Outlook, and images.

In plain words
What is it for?
Use it to convert one file, a folder of documents, or supported URLs, and to prepare source material for a knowledge base or language-model workflow.
Why use it?
Information stored in different file formats is harder for language models and text tools to process consistently. Converting it to Markdown preserves useful structure for reading and analysis.

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

markitdown 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 2mo ago.

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

The opening of the file, as written. The whole thing — 159 lines — stays where its author put it; the contents beside it link to each section on GitHub.

MarkItDown

Convert source material into Markdown optimized for language-model and text-analysis workflows. Preserve useful structure such as headings, lists, tables, links, and metadata; do not promise page-faithful visual reproduction.

Choose a workflow

  • Convert one local file or supported URL: use the markitdown CLI.
  • Convert several local files reproducibly: use scripts/convert.py.
  • Integrate conversion into an application or pass streams: use the Python API.
  • Read standalone images or images embedded in PPTX, DOCX, PDF, or XLSX: run the bundled script with an OpenAI-compatible vision model.
  • Reject audio and video inputs; this Skill does not transcribe them.

Install safely

Require Python 3.10 or newer. Prefer an isolated environment:

python3 -m venv .venv
source .venv/bin/activate
python -m pip install 'markitdown[pdf,docx,pptx,xlsx,xls,outlook]' markitdown-ocr openai

Install only required extras when dependency size matters, for example:

python -m pip install 'markitdown[pdf,docx,pptx,xlsx]'

Do not install markitdown[all] for this Skill because it includes audio-transcription dependencies. Install only the document extras required by the task.

Do not alter a user's project environment without permission. Reuse an existing compatible environment when present; otherwise explain or create an isolated one within the task scope.

Convert content

For one input:

markitdown report.pdf -o report.md
markitdown https://example.com/page -o page.md
cat report.pdf | markitdown > report.md

For multiple local inputs, run:

python scripts/convert.py file.pdf slides.pptx notes.docx --output-dir markdown
python scripts/convert.py source-folder --output-dir markdown

The script recursively converts directories and preserves their relative structure. It preserves each source extension in the output name (file.pdf.md) to avoid collisions. Add --overwrite only when replacing existing outputs is intended.

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.
