Google gives its family agent a separate identity and permission boundary

Google's CC experiment lets up to six people work with one agent that has its own verified Google Account. It separates shared from per-person memory, defines explicit sharing boundaries and integrates Gmail, Chat, Drive, Docs, Calendar and Tasks. The agent runs on an isolated cloud computer using Antigravity and Gemini. Access is an adult, U.S.-only Labs experiment with a waitlist.

For multi-user agents, identity and memory ownership cannot be borrowed from one human account. CC is a concrete design for a shared principal with explicit per-person boundaries. Watch the architecture, but do not infer reliability or adoption from an early consumer experiment with no benchmark data.
