Retell AI Policy Guardrails

Overview

Prerequisites

Instructions

Step 1: SDK Pattern

Error Handling

Examples

Restrict a booking agent to an approved action boundary

Give an appointment agent only the lookup and create-booking tools needed for its flow, with explicit argument validation and a human handoff for refunds, medical questions, or account changes. Test synthetic prompts that attempt each forbidden action and verify that the agent refuses or transfers rather than improvising. Version the policy with the agent and review deviations from the guardrail before widening any permission.
