Guardrails
Safety mechanisms that constrain AI agent behavior, preventing harmful actions, enforcing policies, and ensuring outputs meet quality and compliance standards.
In Depth
Guardrails are essential for production agent deployments. They operate at multiple levels: input guardrails filter harmful or out-of-scope requests, output guardrails check responses for accuracy and policy compliance, and action guardrails prevent agents from taking dangerous or unauthorized actions. Guardrails can be rule-based (regex, allowlists), model-based (a second LLM evaluating the first), or hybrid. They're the difference between a demo agent and a production-ready one.
