## Evaluation Prompt

````text

# Task
Using https://github.com/diffbot/diffbot-python/blob/main/README.md, complete the following task:

Using the Diffbot Python SDK, build me a script that scrapes web content:

1. Install the official Diffbot Python SDK (pip install)
2. Scrape the page at "https://news.ycombinator.com"
3. Extract the top 5 story titles and their URLs
4. Print the results as JSON array with fields: rank, title, url

You MUST use the official Diffbot Python SDK — do not make raw HTTP/REST calls. 

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

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