## Evaluation Prompt

````text

# Task
Using https://docs.extend.ai/, complete the following task:

Using Extend.ai, build me a script that parses this PDF and extracts structured data: https://www.irs.gov/pub/irs-pdf/fw9.pdf

Print the result as JSON with fields: pages (total count), chunks (array of text blocks), tables (array if any found) 

## 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.
