The LinkedIn hook writer skill that actually knows how hooks work
Stop writing openers that disappear into the feed. This Claude skill is trained on 131 real hooks from 21 working LinkedIn creators, and it renders like your phone does.
Most hooks fail before anyone reads them. Not because the idea is bad, but because the opener takes up too much space and LinkedIn cuts it before the point lands. This skill uses a pixel-width model, not a character count, because W and I are not the same width on your screen. It estimates exactly how your hook renders on mobile, then writes around that.
