Prompt guide

Ask normally Direct answer. High-Extract books (thin training coverage) surface automatically when relevant.
Give me a citation-tiered answer on X Every claim labeled by evidence: injected chapter · catalogue level · training knowledge.
What's your confidence on X? Flags uncertainty and names the library book that would ground the claim.
Which books should I extract for X? Focuses recommendations on High-Extract books for the topic.

Tip: for deep reading questions, ask once without chapters selected to get a strategic frame, then select the chapters and ask again — the second answer combines strategic thinking with grounded chapter detail.

Note: section-level detail from High-Extract books may be imprecise — training coverage is thin. Verify specific section references in the physical book before acting on them.
