markitdown

markitdown is a skill for Claude Code from LuizEduPP/Rememb. It costs 48 tokens per session (3,122 once invoked), scanned B, original, MIT.

A file-conversion guide that turns PDFs, office documents, images, audio, HTML, archives, and structured data into Markdown, a plain-text format organized with headings and lists.

In plain words
What is it for?
Extracting document contents into Markdown, converting office files or web pages, reading scanned documents with OCR, transcribing audio, and preparing mixed files for analysis.
Why use it?
Markdown is easy for people and language models to read, search, and reuse. The workflow also covers OCR for scanned images and transcription for audio.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python scripts/generate_schematic.py "your diagram description" -o figures/output.png.

Good fit Extracting document contents into Markdown, converting office files or web pages, reading scanned documents with OCR, transcribing audio, and preparing mixed files for analysis.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 1mo 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.

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

MarkItDown - File to Markdown Conversion

Overview

MarkItDown is a Python tool developed by Microsoft for converting various file formats to Markdown. It's particularly useful for converting documents into LLM-friendly text format, as Markdown is token-efficient and well-understood by modern language models.

Key Benefits:

  • Convert documents to clean, structured Markdown
  • Token-efficient format for LLM processing
  • Supports 15+ file formats
  • Optional AI-enhanced image descriptions
  • OCR for images and scanned documents
  • Speech transcription for audio files

Visual Enhancement with Scientific Schematics

When creating documents with this skill, always consider adding scientific diagrams and schematics to enhance visual communication.

If your document does not already contain schematics or diagrams:

  • Use the scientific-schematics skill to generate AI-powered publication-quality diagrams
  • Simply describe your desired diagram in natural language
  • Nano Banana Pro will automatically generate, review, and refine the schematic

For new documents: Scientific schematics should be generated by default to visually represent key concepts, workflows, architectures, or relationships described in the text.

How to generate schematics:

python scripts/generate_schematic.py "your diagram description" -o figures/output.png

The AI will automatically:

  • Create publication-quality images with proper formatting
  • Review and refine through multiple iterations
  • Ensure accessibility (colorblind-friendly, high contrast)
  • Save outputs in the figures/ directory

When to add schematics:

  • Document conversion workflow diagrams
  • File format architecture illustrations
  • OCR processing pipeline diagrams
  • Integration workflow visualizations
  • System architecture diagrams
  • Data flow diagrams
  • Any complex concept that benefits from visualization

For detailed guidance on creating schematics, refer to the scientific-schematics skill documentation.

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.

markitdown is a skill published in the GitHub repository LuizEduPP/Rememb (5 stars, last pushed 12d ago), licensed MIT. It adds 48 tokens to every session and 3,122 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
