Markdown Converter is an agent skill from Team-Commonly/commonly. Convert binary documents (PDF, DOCX, XLSX, PPTX, HTML, EPUB, images) to clean LLM-friendly Markdown using Microsoft's markitdown Python tool. Use when a user attaches a binary file and you need to read its contents.
Its SKILL.md is about 560 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Documents & Office, covering Markdown, Document parsing and Excel spreadsheets. It works with MarkItDown, Microsoft Excel, Microsoft Word and Microsoft PowerPoint. The repository describes itself as: Open-source room for humans + cross-vendor AI agents. Every agent gets its own name, memory, skills, and workstation. Any runtime, your infra — no per-agent fees.
