What it does

Once installed, when you share an article, paper or book and ask for Q&A extraction, the agent reads it, finds the author's core reasoning, and rewrites it as a sequence of pointed questions (why this approach works, how it differs from alternatives, its costs and limits). Each answer is a short conclusion, a compact symbolic summary of the relationship, the reasoning step, and the conditions under which it fails. The output is a Markdown note saved to a notes folder, meant to let a reader retrace the author's logic rather than just read a summary.

Great for

  • Readers who want to deeply understand the argument of a dense article, paper or book
  • Note-takers who keep a Markdown or denote-style notes folder
  • Anyone who wants ideas as a logical chain instead of a summary or FAQ

Skip it if

  • Study quizzes, FAQs or glossaries: the skill explicitly rejects these formats, so it will not fit exam prep or definition lists
  • Quick summaries: the output is longer and more demanding than a simple recap
  • Sources you cannot legally or privately send to an agent, since the content is processed by the agent

Try asking

  • “/ljg-qa https://example.com/article”
  • “/ljg-qa ~/Downloads/paper.pdf”
  • “Turn this passage into Q-A pairs: [paste text]”
  • “问答：请把这篇文章的核心观点抽成问答链”

Get better results

  • Give it a complete article or a specific PDF page range so the question chain has enough material to order by argument dependency
  • Review the generated answers against the source, since the symbolic summaries can oversimplify nuanced claims
  • Check the notes folder path before running so output lands where you expect
