Summarize Skill

Turn URLs, PDFs, Word docs, PowerPoints, HTML pages, text files, and more into Markdown so they can be inspected, quoted, and processed like normal text.

markitdown can fetch URLs directly; this skill wraps it to make saving + summarizing convenient.

Tool

•scripts/to-markdown.ts

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

Run from this skill folder (the folder containing SKILL.md).

Convert a URL or file to Markdown

bash

uvx markitdown <url-or-path>

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

bash

./scripts/to-markdown.ts <url-or-path> --tmp

Tip: when summarizing, the script always writes the full converted Markdown to a temp .md file and always prints a final hint line with the path.

Write Markdown to a specific file:

bash

./scripts/to-markdown.ts <url-or-path> --out /tmp/doc.md

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

Summaries work best when you provide what you want extracted and the audience/purpose.

bash

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

Or:

bash

./scripts/to-markdown.ts <url-or-path> --summary --prompt "Focus on security implications and action items."

This will:

•convert to Markdown via uvx markitdown
•write the full Markdown to a temp .md file and print its path as a hint line
•run pi --model claude-haiku-4-5 (no-tools, no-session) to summarize using your extra prompt

Notes

•Requires Bun (#!/usr/bin/env bun).
•Requires uvx markitdown and pi on PATH.
