What this checks
Three measurements that almost no other tool runs. Answer extractability counts how many of your sections are bounded by a heading, how many open with a short direct answer rather than a windup, whether any headings are phrased as questions, and whether there are tables or lists to lift. Attribution looks for a named author, Person or Organization schema, and outbound links to primary sources. Readability scores sentence and word complexity, because dense prose is harder to quote as well as harder to read.
