Challenge an outbound campaign copy by benchmarking it against the user's existing campaigns — what worked, what didn't, what the winners do differently — and return a concrete verdict plus prioritized fixes. Use whenever the user wants to know if a campaign or sequence is good, compare a draft to past campaigns, audit campaign copy against real performance, pressure-test a sequence before launch, validate a sequence before going live, or asks 'is this campaign as good as my best ones'. Triggers on: 'challenge this campaign', 'benchmark this sequence', 'is this campaign good', 'audit my copy', 'pressure-test before launch', 'compare to my best campaigns', 'should I launch this'. Pulls existing campaign performance from the La Growth Machine MCP when connected; otherwise works from stats and copy the user pastes; falls back to a best-practice baseline when there is no campaign history. For SDR, RevOps, Growth, Head of Sales/Marketing, founders launching outbound. Maintained by La Growth Machine.

One book → a clear "Viewfinder" → a 2050 Library Borrow Card (PNG). The card includes the real book cover, author's avatar, and book information; the Viewfinder block fully, fluently, and clearly expresses the book's unique "way of seeing the world". The illustration block uses a hand-drawn explanatory style with white background and black ink, featuring the ink portrait of Ji Gang himself (created by cutting out his avatar), turning this set of ideas into a vivid, easily understandable scene. Light optical glass style, the card's accent color is dynamically extracted from the book cover, with adaptive width and height. Remember this "pair of eyes" after closing the book, and your reading won't be in vain. Use when user says '取景框卡', '图书馆卡', 'library card', '书卡', '铸书卡', '一本书一句话一张卡', '/ljg-library', or provides a book name and wants it distilled into one collectible card. NOT FOR book structure analysis (use ljg-book), pure text golden quotes (use ljg-card -b), infographics (use ljg-card -i), visual notes (use ljg-card -v).
