Sitemap Checker
Find a site's sitemap through robots.txt or /sitemap.xml and check that it parses.
Follows the Sitemap directive in robots.txt, falling back to the conventional /sitemap.xml, and verifies the result is well-formed XML. A sitemap is how a crawler discovers pages it would not reach by following links, which matters as much to an AI agent as to a search engine.
This is one of the checks the AI Agent Readiness Checker scores under Discoverability, and it can also be run on its own for any URL.
