why the hook is the whole post
On X the first line does 90% of the work. If it doesn't stall the thumb, the rest of the post never gets read, and a great point dies at 300 impressions. The strongest hooks are tight, concrete, and leave a question the reader has to resolve. This tool checks for exactly those signals so you can fix a hook before you post, not after it flops.
