## Evaluation Prompt

# Task
Using https://[REDACTED:TENANT].bolna.ai/[REDACTED:TENANT], complete the following task:

Using the Bolna REST API, build me a script that creates a voice AI agent:

1. Use the Bolna REST API (no SDK - use the requests library)
2. Create a simple voice AI agent with a greeting message
3. List available agents to confirm creation
4. Print the result as JSON with fields: agent_id, agent_name, created

Use HTTP requests to call the Bolna API. 

## Execution
After creating the script, run it to verify it works:
```bash
cd /home/daytona/[REDACTED:TENANT] && python <your_script>.py
```

The script should print output to stdout. If there are errors, debug and fix them until it runs successfully.
