Agents hosted on Google infrastructure navigating the web and taking actions on a user's request. Google names one prefix list for it — user-triggered-agents.json — and is separately experimenting with Web Bot Auth under the identity https://agent.bot.goog.
Google-hosted agents cannot complete a task on your site for a user who asked them to. This is the agentic-commerce fetch: blocking it removes you from what an assistant can actually do rather than from what it can say.
