description	Fetch a URL or convert a local file (PDF/DOCX/HTML/etc.) into Markdown using `uvx markitdown`, optionally it can summarize
license	https://github.com/mitsuhiko/agent-stuff

Turn “things” (URLs, PDFs, Word docs, PowerPoints, HTML pages, text files, etc.) into Markdown so they can be inspected/quoted/processed like normal text.

markitdown can fetch URLs by itself; this skill mainly wraps it to make saving + summarizing convenient. For PDF inputs, use the markitdown[pdf] extra (or the wrapper below, which now does this automatically).

When to use

Use this skill when you need to:

• pull down a web page as a document-like Markdown representation
• convert binary docs (PDF/DOCX/PPTX) into Markdown for analysis
• quickly produce a short summary of a long document before deeper work

Quick usage

Convert a URL or file to Markdown

Run from this skill folder (the agent should cd here first):

uvx --from 'markitdown[pdf]' markitdown <url-or-path>

To write Markdown to a temp file (prints the path) use the wrapper:

node to-markdown.mjs <url-or-path> --tmp

Tip: when summarizing, the script will always write the full converted Markdown to a temp .md file and will always print a final "Hint" line with the path (so you can open/inspect the full content).

Write Markdown to a specific file:

uvx --from 'markitdown[pdf]' markitdown <url-or-path> > /tmp/doc.md

Convert + summarize with haiku-4-5 (pass context!)

Summaries are only useful when you provide what you want extracted and the audience/purpose.

node to-markdown.mjs <url-or-path> --summary --prompt "Summarize focusing on X, for audience Y. Extract Z."

Or:

node to-markdown.mjs <url-or-path> --summary --prompt "Focus on security implications and action items."

This will:

1. convert to Markdown via uvx --from 'markitdown[pdf]' markitdown
2. write the full Markdown to a temp .md file and print its path as a "Hint" line
3. run pi --model claude-haiku-4-5 (no-tools, no-session) to summarize using your extra prompt
