  "description": "The fetcher used by AI agents hosted on Google infrastructure to navigate the web and perform actions on behalf of a user who asked for them. Google publishes a dedicated IP range list for it and signs a subset of its requests with Web Bot Auth under the agent.bot.goog identity. As a user-triggered fetcher it generally ignores robots.txt rules.",
