Prompt

Please convert `contracts/vendor_agreement.docx` into markdown format. I don't think the MCP markitdown server is installed. How should this be handled?

Document Conversion

Convert documents and URLs to markdown using a three-tier fallback strategy. This skill is infrastructure: consumer skills reference it via dependency rather than reimplementing conversion logic.

When To Use

Converting PDF, DOCX, PPTX, XLSX, HTML, or images to markdown for downstream processing
Any skill that ingests external documents
File format is not plain text or markdown

When NOT To Use

Content is already markdown or plain text
You only need to read a small text file (use Read directly)

Format Detection

Identify the document type from the URI before converting.

Extension	Format	Tier 1	Tier 2
`.pdf`	PDF	Yes	Read tool (pages)
`.docx`, `.doc`	Word	Yes	None
`.pptx`, `.ppt`	PowerPoint	Yes	None
`.xlsx`, `.xls`	Excel	Yes	None
`.html`, `.htm`	HTML	Yes	WebFetch
`.csv`	CSV	Yes	Read tool
`.json`	JSON	Yes	Read tool
`.xml`	XML	Yes	Read tool
`.png`, `.jpg`, `.jpeg`, `.gif`, `.webp`	Image	Yes	Read tool (visual)
`.mp3`, `.wav`, `.m4a`	Audio	Yes	None
`.zip`	Archive	Yes	None
`.epub`	E-book	Yes	None

See modules/format-matrix.md for quality comparison across tiers.
