Why it matters
Jack Wotherspoon’s Gemini Managed Agents walkthrough separates interaction history from the sandbox filesystem. A research agent writes an artifact that later agents read using the same environment identifier and fresh conversation contexts. The talk also describes proxy-injected credentials. The demo establishes a workflow pattern, not a security guarantee or verified investment forecast.
My takeaway: Prototype handoffs with synthetic data: have one agent write a versioned artifact, then start a fresh interaction in the same environment and check what persists. Validate artifact contents before downstream use. Test access boundaries and cleanup; keeping a secret outside the sandbox does not prevent misuse of authorized API calls.
