AI agent — An AI system that doesn't just answer once but works toward a goal in a loop — taking actions, reading the results, and deciding what to do next.
Why it matters
Sites can expose real tool calls to browser agents instead of leaving them to guess their way through human-oriented HTML.
Key quotes
“The web was built on the assumption that there is a person on the other end: someone to read the page, click buttons, and fill in the forms.”
“The usual approach has been crawlers, which copy content back to a server and, too often, give the original site none of the traffic and little of the credit.”
“This enables agents to have a different browsing experience from the user and use tokens on tasks, not navigation.”
