We just shipped Strands Box, now in developer preview. It's an open source sandbox for developers building applications that run AI agents, and it helps control what an agent can reach and do. You write the rules in Dogwood. Box enforces them at the OS and network boundary, not by asking the agent to behave. Glad to see this next step in AWS's approach to AI agent safety: giving developers greater control as agents take on more responsibility.
