Episode notes
Browsers As The Prime Agentic Platform
- Browsers are the likely dominant platform for agentic AI because they have the widest distribution today.
- Jaden Schaefer argues browsers are the best current form factor short of full system-level agents.
Metadata-Only Critic To Prevent Prompt Injection
- Google uses a separate Gemini-based critic that checks each agent action against the user's original goal.
- The critic only sees metadata about the plan, preventing prompt-injection via screen content.
Origin-Level Read/Write Controls
- Agent Origin Sets limit which web origins are readable and which are writable to the agent.
- This bounds cross-origin data leaks by preventing agents from consuming irrelevant content like banner ads.
