About this skill

Problem

Long documents, web pages, and PDF files often include navigation, ads, tables of contents, and formatting noise, which can distract summarization or hide the main points. Document Summarize targets this by first extracting readable text and then producing a structured summary using fixed analysis dimensions.

How it works

  • Web pages: fetch HTML with WebFetch, then clean non-content markup using scripts/clean_html.py.
  • Files: use scripts/extract_pdf.py for PDF files, read MD and TXT files directly, and analyze pasted text or code snippets from the conversation.
  • Analysis dimensions: identify the topic, section structure, key entities, core arguments, data or facts, and action items.
  • Output: generate an executive summary, section highlights, conclusions, and recommended sections for long content; compress short content into a one-line overview and key points.

Boundaries

The skill depends on accessible text and cannot process image-only pages, video, or login-protected content. PDF extraction may require pypdf; if extraction fails, convert the file to text or Markdown. Summaries remain faithful to the source and avoid external inference; very short input is returned with a note that summarization is unnecessary.

Use Cases

  • After receiving a competitor’s launch page, extract the main text, key claims, and data for review notes.
  • Convert a client contract PDF to text, then summarize clauses, amounts, dates, and action items.
  • Paste a long technical blog post or paper excerpt and ask for a readable summary by section, entities, and conclusions.
  • Inspect a URL by extracting only readable body text and removing navigation noise before deciding whether to store it.

Best For

  • Content editors assembling web material: they need body text, key claims, and quotable data from news pages.
  • Legal assistants handling contracts and reports: they need PDF clauses, amounts, dates, and action items summarized for review.
  • Engineers tracking technical resources: they want long articles, papers, or API docs compressed into section points and key entities.
  • Platform operators managing knowledge bases: they need to judge whether web body text is usable and extract topics, facts, and action items.
