Guardrails

Safety controls around an AI system that constrain what it can say or do — filtering harmful content, limiting tool access, and enforcing policies.

Essential for agents that act on real systems: cap loop counts, require approval for irreversible actions, and log every tool call. Managed platforms like Bedrock ship guardrails as a built-in feature.
