> Retell AI voice agent policy guardrails: restricting which tools and actions an agent can use, valid

Retell AI voice agent policy guardrails: restricting which tools and actions an agent can use, validating arguments, and handing off to a human for refunds, medical questions, or account changes, using the retell-sdk in TypeScript. Use when building or reviewing Retell AI phone agents that must stay within an approved action boundary, or when testing that an agent refuses or transfers forbidden requests.

# Retell AI Policy Guardrails

## Overview

Implementation patterns for Retell AI policy guardrails — voice agent and telephony platform.

## Prerequisites

- Completed `retellai-install-auth` setup

## Instructions

### Step 1: SDK Pattern

```typescript
import Retell from 'retell-sdk';
const retell = new Retell({ apiKey: process.env.RETELL_API_KEY! });

const agents = await retell.agent.list();
console.log(`Agents: ${agents.length}`);
```

## Output

- Retell AI integration for policy guardrails

## Error Handling

| Error | Cause | Solution |
|-------|-------|----------|
| 401 Unauthorized | Invalid API key | Check RETELL_API_KEY |
| 429 Rate Limited | Too many requests | Implement backoff |
| 400 Bad Request | Invalid parameters | Check API documentation |

## 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.
