Recommend what to read next
Read ../books-library/SKILL.md first to choose the authoritative backend,
then read ../books-library/references/recommendations.md.
Analyze the last 15 books read in the selected library, using the backend's actual reading-date field. Look for series continuity, recent page-count fatigue, recently added books, older forgotten books, and highly rated TBR books. Exclude archived Calibre books and keep Goodreads recommendations on the TBR unless the user asks for a broader pool.
Return a concise reading-pattern summary followed by one to three suggestions in each useful category: series continuity, recently added, forgotten gems, quick reads, and highly rated books. Include the evidence behind each choice and say when a category has no matches.
