This isn't good UX for machines. This is a patch for bad UX to help LLMs out in those cases. Some websites have the same patch for humans in the form of a "Help" or "About" section that details how the page is to be used/interpreted. This essentially just places those same instructions into a well-known location, so that LLM-based agents don't first have to crawl the website for such an instructional page (which may or may not exist). If you have good UX these instructions should be largely moot for both machines and humans, and bring machines on the same page as humans that may have additional context (e.g. where the site was linked; previous visits to the website).
