Agent Context Isolation

Agent context isolation is the enforcement of boundaries between the execution contexts of different agents, ensuring that one agent's memory, credentials, tool state, and intermediate data cannot be read or modified by another agent without explicit permission.

It is the agent-level equivalent of process isolation in operating systems, and is essential for preventing cross-agent contamination and side-channel attacks in shared infrastructure.
