Agent

An agent is an AI tool that can take actions, such as browsing pages or filling a form, rather than only writing an answer.

In a little more detail

Agents fetch pages the way a person would, so a site that only works after heavy code runs is a site an agent struggles with too. The readability work is the same work.
