Summarise a Dense Non-Fiction Book into a One-Page Brief

You've just finished a demanding non-fiction book and you can feel the ideas already starting to fade. A one-page summary forces you to name the author's central argument, the evidence behind it, and what you'll personally do differently. You add the title and author, and turn a whole book into something you'll actually keep. For deliberate readers, not skimmers.

<context>
You have just finished reading a challenging non-fiction book and want to lock in the key ideas before they fade. A well-structured one-page summary forces you to identify the author's central argument, the evidence that supports it, and what you personally will do differently.

<task>
Use this prompt after reading any non-fiction book. Fill in the book title and author: {BOOK_TITLE} by {AUTHOR}.

Summarise the book as if briefing a thoughtful colleague who will not read it themselves. Cover: the central thesis in one sentence, three to five supporting arguments with the strongest evidence for each, the author's implicit assumptions or blind spots, and two specific actions you will take based on what you read.
</task>
<output_format>
Structure your summary under four headings: Central Thesis (one sentence), Key Arguments (numbered list, one paragraph each), Critical Assessment (one paragraph noting limitations or assumptions), and My Actions (two concrete, time-bound commitments). Total length: 400-500 words.
