markitdown

markitdown is a skill for Claude Code, Codex from agentlas-ai/agentlas-desktop. It costs 61 tokens per session (2,745 once invoked), scanned A, a copy of markitdown, Apache-2.0.

A document-conversion utility from Microsoft that turns files and selected web responses into Markdown, plain text written with simple formatting. It handles common Office files, PDFs, web pages, data files, and other supported inputs.

In plain words
What is it for?
Use it to convert local files, file streams, or validated web responses into Markdown for text analysis, search, and retrieval-augmented generation (RAG), a method of supplying documents to an AI model during a query.
Why use it?
It provides text that is easier to search, analyze, index, or give to a language model, without promising an exact visual copy of the original document. Separate OCR or extraction services may be needed for scans, layouts, or rich media.

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 1mo ago.

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

MarkItDown

Overview

MarkItDown is Microsoft's lightweight Python utility for turning common documents into structure-preserving Markdown. Its output is designed primarily for indexing, text analysis, search, and LLM ingestion—not high-fidelity visual reproduction.

This skill targets MarkItDown 0.1.6, released May 26, 2026. New code should use result.markdown; result.text_content remains only as a soft-deprecated compatibility alias.

Choose the Right Path

Need Recommended path
Trusted local PDF, Office, HTML, CSV, EPUB, or ZIP Built-in converter with convert_local()
Uploaded bytes or an already-open file convert_stream() with StreamInfo hints
Remote HTTP(S) input Validate and fetch it yourself, then call convert_response()
Scanned PDF or text inside embedded images Official markitdown-ocr vision plugin, Azure Document Intelligence, or Azure Content Understanding
Video, structured fields, or custom multimodal extraction Azure Content Understanding
Local agent integration Official markitdown-mcp server over STDIO or localhost
Bounding boxes, page coordinates, or screenshots Use a layout-aware parser such as LiteParse instead
PDF merge/split/forms/watermarks Use the pdf skill instead

Installation

Create an isolated environment:

uv venv --python 3.12 .venv
source .venv/bin/activate

Install every built-in feature:

uv pip install "markitdown[all]==0.1.6"

Or install only the converters required by the task:

uv pip install "markitdown[pdf,docx,pptx,xlsx]==0.1.6"

Available extras in 0.1.6 are:

  • pptx, docx, xlsx, xls, pdf, and outlook
  • audio-transcription and youtube-transcription
  • az-doc-intel and az-content-understanding
  • all

Verify the installation:

markitdown --version
python scripts/inspect_installation.py

The [all] extra does not install the separate markitdown-ocr plugin or an OpenAI-compatible client.
