Humans want to see a good-looking website, even just raw HTML. An agent doesn't even need that, ideally they would just see the content of the page in markdown.

Why not have an agent version? It saves the client agent and the website host time and money.

It would be nice if there was a standard like llms.txt to specify "agents should instead visit this mirror of the website that is a raw markdown version of what humans see"

Also, part of agent readiness on this website is the AI equivalent of SEO (or the opposite if you don't want your website being crawled for AI).
