## Evaluation Prompt

# Task
Using https://docs.sprites.dev/api/v001-rc30/, complete the following task:

Using Sprites, build me a script that runs a multi-step computation inside a Sprites sandbox:
        
1. Use the Sprites Python SDK to create/connect to a sandbox
2. Inside the sandbox, execute the following pipeline:
   a. Install the `sympy` package using pip
   b. Run a Python script that:
      - Computes the 10th Fibonacci number iteratively
      - Uses sympy to check if that number is prime
      - Prints the result as JSON: {"fibonacci_10": <number>, "is_prime": <boolean>}
3. Capture the sandbox execution output and print it to stdout

All computation must run inside the Sprites sandbox, not in your local Python process. Do not use subprocess — use the Sprites SDK's execution primitives. 

## 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.
