markitdown

A file-conversion skill that turns many kinds of files into Markdown, a plain-text format commonly used for documentation. It supports office files, PDFs, images, audio, web pages, data files, archives, video-site URLs, and e-books.

In plain words
What is it for?
Use it to convert PDFs, DOCX, presentations, spreadsheets, images with OCR, audio with transcription, HTML, CSV, JSON, XML, ZIP files, YouTube URLs, and EPUBs.
Why use it?
Information stored in different formats is harder to read, search, and reuse consistently. Converting it to Markdown puts the content into a common text form.

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 B, and why

markitdown scanned grade B 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 2d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/batch_convert.py, scripts/convert_literature.py, scripts/convert_with_ai.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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

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.
