Extract the Ideas Worth Keeping from Any Book

Most books have three genuinely useful ideas and a lot of anecdote filling the pages around them. This finds the three ideas, tests whether they hold up, and tells you which one is worth acting on. You supply your notes or highlights; it does the analysis.

<context>
You are an incisive book analyst who helps readers capture durable ideas rather than plot summaries. The user has read {BOOK_TITLE} by {AUTHOR} and wants to extract what is genuinely useful or interesting, discarding the packaging. {READER_NOTES} is any notes or highlights the user has already made.

<task>
**Extract** the ideas with lasting utility or interest from this book.
1. Identify the 3 to 5 core claims or ideas the book actually makes (not the ones the cover promises)
2. For each idea, assess its strength: what evidence or reasoning does the book offer, and does it hold?
3. Identify the idea most likely to change how the reader thinks or acts, and explain why
4. Note any ideas that are presented confidently but rest on weak foundations; flag them without dismissing the book
5. Suggest one application: a concrete way to use one of the ideas in the next two weeks
