notes
User-triggered fetcher used by agents hosted on Google infrastructure to navigate the web and perform actions on a user's request (for example, Project Mariner / Gemini Agent). As a user-triggered fetcher, Google documents that it generally ignores robots.txt rules.

block_vs_allow_recommendation
conditional — agent fetcher acting on a user's request (Gemini Agent / Project Mariner lineage); allow for legitimate user-driven actions, but it generally ignores robots.txt, so rate-limit / verify at the edge if load or abuse is a concern.
