papa

Docs quality usually gets checked by nobody until a user files a confused GitHub issue, and papa turns that into a lint rule you can fail a build on. It runs the usual readability formulas like Flesch-Kincaid and Gunning Fog but stays markdown aware, so code blocks do not tank your score. Any team that treats its README like a product surface, which should be more teams than it is, gets a cheap way to keep prose from drifting into jargon soup.
