Report #55486

[frontier] Multi-agent systems leak context between agents during handoffs, causing agents to hallucinate tools or data they don't have access to because they see other agents' scratchpads

Implement strict namespace isolation where each agent operates in a sandboxed context namespace; handoffs explicitly declare which variables are passed \(pass-by-value\), preventing implicit context sharing

Journey Context:
Frameworks like Swarm or AutoGen default to shared context or simple message passing. Production systems need isolation. The frontier pattern treats agent handoffs like process spawning: each agent gets a clean environment \(namespace\) with only explicitly passed parameters. This uses MCP or similar to enforce that agents cannot see the 'supervisor's' full context. This prevents 'confused deputy' problems where Agent B uses a tool that Agent A was authorized for but B is not. It enables true multi-tenancy where different users' data stays isolated across agent teams.
