AgentGuard gives operations teams a way to let AI agents handle refund requests while retaining control over which actions can execute. In the Control Tower, a model interprets a customer message and proposes a refund. A separate policy engine checks permissions and transaction limits before the sandbox executor can act. The demo shows four outcomes with synthetic transactions. A €125 refund executes automatically, a €300 refund waits for human approval, a €750 refund is denied, and an ambiguous request asks for clarification. The Control Tower also shows how a paused workflow can resume after a restart and produce a single simulated receipt. The event-built Control Tower and RequestGuard are in the public submission repository. The earlier AgentGuard prototype is excluded.
