Frequently asked questions
No. llms.txt is a community proposal, not a ratified standard, so nothing can claim to validate it in the way an XML schema validates a sitemap. These checks test something more useful: whether an assistant that fetches only this file can tell what your site is, find the right page, and resolve every link.
