Prompt Recreated prompt

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: Sort my messy invoice folder: rename each file clearly and move it into the right folder.

Quick check first: Which folder holds the invoices, and how do you want them grouped?

What I need from you:
- The folder of invoices
- Your folder structure (for example by year or vendor)

Rules:
- Read each file and rename it as 'YYYY-MM-DD Vendor - Invoice - ProductOrService.pdf'.
- Move each invoice into the right folder.
- If something is missing or unclear, ask me instead of guessing.
- Don't delete anything. Show me a few examples before doing the whole folder.

Output: A tidy, renamed folder plus a list of files you weren't sure about.

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

You'll know it worked when: every invoice has a clear name and sits in the right folder for tax time.
