markitdown skillA

markitdown is agent-read markdown (skill) from marielynneblock/arcanum-artifex: Convert files and office documents to Markdown. Supports PDF, DOCX, PPTX, XLSX, images (with OCR), audio (with transcription), HTML, CSV, JSON, XML, ZIP, YouTube URLs, EPubs and more..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add marielynneblock/arcanum-artifex/markitdown@git:20260710.0115f49
Exact content
mdr add marielynneblock/arcanum-artifex/markitdown@sha256:772fc63daea5cf2d

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
