Markdown Converter
This wraps Microsoft's markitdown tool so Claude can convert pretty much anything to Markdown without you installing dependencies. PDFs, Office docs, spreadsheets, presentations, images with OCR, even audio transcription and YouTube URLs. It uses uvx to run on demand, which means the first conversion caches things but after that it's fast. The real win is feeding messy formats into LLM context windows without manual copy-paste gymnastics. For stubborn PDFs, you can point it at Azure Document Intelligence for better extraction. Straightforward utility that does one thing well.
