Policy Enforcement Over Prompts: Securing AI Agent Actions in Production

As AI agents transition from text generation to performing real-world actions—issuing refunds, accessing customer data, and managing production systems—relying solely on system prompts for security becomes inadequate. This piece introduces Enforra, an open-source SDK that enforces policy decisions at the tool-execution level before actions are taken, shifting control from guidance within prompts to explicit policy checkpoints. This approach is critical as agents increasingly interact with production workflows where mistakes have real consequences.
