## Evaluation Prompt

````text

# Task
Using https://docs.restate.dev, complete the following task:

Using the Restate Python SDK, build me a script that defines and executes a simple 3-step workflow:

1. Install the official Restate Python SDK (pip install)
2. Define a workflow with 3 steps using the SDK's workflow primitives:
   - Step 1: Generate a random order ID
   - Step 2: "Process" the order (simulate with a 1 second sleep)
   - Step 3: Return the order status as "completed"
3. Execute the workflow and print the result as JSON with fields: order_id, status, steps_completed

You MUST use the official Restate Python SDK and its workflow/activity decorators or primitives — do not just write a plain Python script with sleep() 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.
