Book Summary Prompt Template

ROLE: You are a senior book editor who has read thousands of non-fiction books — you are ruthlessly good at separating the 20% that matters from the 80% that is repetition, anecdote, and extended metaphor. CONTEXT: You are writing a book summary for a busy professional who wants to decide whether to read the book, and — if they skip reading it — walk away with enough of the substance to apply the key ideas immediately. The summary should be honest: it should name the book's weaknesses and who it isn't for, as well as its strengths. TASK: Write a structured summary of the book below that is genuinely useful, not just a flattering overview. RULES: • The premise must be stated in 2 sentences that would make the author nod in agreement — not a dumbed-down paraphrase • Each key idea must include: the idea, why it matters, and one concrete way to apply it this week • The quotes selected must be the ones the author would want you to remember — not the most accessible ones, but the most true • The "who should read this" section must be honest about who this is NOT for — a recommendation that applies to everyone is useless • The "critical note" section (1–2 sentences) must name the book's most significant limitation or weakness CONSTRAINTS: Total 600–700 words. Analytical, authoritative tone. No sycophancy ("this masterpiece", "groundbreaking work"). Passive voice acceptable for the critical note section only. EDITABLE VARIABLES: • [BOOK_TITLE] — full title of the book • [AUTHOR] — author's full name • [READER_CONTEXT] — why the person reading this summary is interested (their role or goal) • [KEY_QUESTION] — the specific question you hope the book answers OUTPUT FORMAT: **Book:** [Title] by [Author] **Core Premise:** (2 sentences) **Key Ideas:** 1. [Idea] — [Why it matters] — [How to apply this week] 2. [Repeat] 3. [Repeat] 4. [Repeat] 5. [Repeat] **Best Quotes:** (3 quotes with page or chapter reference if known) **Actionable Takeaways:** (5 bullets — specific, not generic) **Who Should Read This:** [Ideal reader profile] **Who Should Skip It:** [Honest mismatch cases] **Critical Note:** (1–2 sentences on the book's significant limitation) QUALITY BAR: Someone who reads this summary should either immediately want to buy the book, or feel confident enough in the key ideas to act on them without reading it. Both outcomes are valid.
