How readable is a site to AI agents?

The checker reads a site's /llms.txt and the pages it lists, the way an agent would, and scores it from 0 to 100.

Five checks, 100 points. The same code runs here, in the badge and in the CLI. Only the first 10 links in an llms.txt are checked, so big files are scored on a sample.

Check Points
/llms.txt exists, valid H1 title, ≥1 section 20
Summary blockquote under the title 15
Markdown copies of listed pages (the link is markdown, or the page has a markdown version) 25, proportional
Listed pages show text without JavaScript 20, proportional
Links in llms.txt resolve (2xx) 20, proportional
