Concise but complete summaries of sections, chapters, or page ranges from textbooks and reference books (for example CLRS, math and engineering texts), with nothing important dropped. Use this skill whenever the user shares a section, chapter, PDF, photo, or pasted text from a book and asks to summarize, condense, digest, "give me the key points", or says they have no time to read it all, even if they do not say "digest".
