The source did not publish its exact prompt. This one is our reconstruction from what the source describes.

Not sure how to start? Tell me what you're trying to get done and I'll help you turn it into a clear request.

Goal: Port my app's backend to a new platform.

Quick check first: Which parts of the backend matter most to get right first?

What I need from you:
- Your codebase
- Access to the new platform

Rules:
- List anything you couldn't port cleanly.
- If something is missing or unclear, ask me instead of guessing.
- For safety, keep my original code untouched until I've reviewed the port.

Output: The ported backend on a branch plus a list of known issues.

If any of this is unclear, tell me what you have and I'll help fill the gaps.

You'll know it worked when: the app runs on the new backend and you have a short bug list to finish.
