Retell AI Local Dev Loop

Name: retellai-local-dev-loop
Author: jeremylongshore

Overview

Implementation patterns for Retell AI local dev loop — voice agent and telephony platform.

Prerequisites

Completed retellai-install-auth setup

Instructions

Step 1: SDK Pattern

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 local dev loop

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

Iterate on a prompt with a deterministic local test set

Keep a small suite of synthetic caller intents, including a successful request, an unclear request, and a required human handoff. Run that suite against a development agent after each prompt or tool-schema change and compare only redacted outcomes such as route, tool arguments, and completion state. Do not point local development at a production phone number; publish a versioned preview only after the suite continues to meet its expected behavior.
