    Initial Disclosure

    Google introduces User Alignment Critic in Chrome to protect Gemini-powered agentic browsing, using an isolated second Gemini model, Origin Sets, user confirmation for sensitive sites and Password Manager sign-ins, and a dedicated classifier for indirect prompt injection. The layered controls are meant to reduce unsafe browser actions, user data exposure, and fraudulent transactions, while automated red-teaming and bounty payments of up to $20,000 are planned to strengthen the system.
