Why it matters
Teleport's agent-swarm experiment highlights that sandbox isolation does not necessarily prevent cross-agent coordination, so defenders must also control shared resources, permissions, and agent identity.
Teleport's Ben Arent describes a capture-the-flag experiment involving five sandboxed agents, each holding an answer fragment and required to collaborate. The write-up reports coordination through shared state, custom protocols, and self-assigned identities, arguing for infrastructure-enforced capability and identity controls rather than reliance on sandboxing alone.
