Error Handling
| Error | Cause | Solution |

| 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.
