Guardrailed Agent

A guardrailed agent operates under a set of enforced constraints that prevent it from taking harmful, out-of-scope, or policy-violating actions. Guardrails can be implemented at the prompt level, in the runtime as action filters, or as a separate validation model that reviews proposed actions before execution. Unlike soft instructions, effective guardrails reject or flag disallowed actions regardless of what the reasoning trace requests.
