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: Match my tax checklist spreadsheet against the receipts in my folder, so I know what's ready for my accountant and what's missing.

Quick check first: Which tax year is this for?

What I need from you:
- The spreadsheet where you track what to send your accountant
- The folder where you drop your receipts

Rules:
- Go through each line in the spreadsheet and find the matching receipt.
- Mark which items have a receipt and which are missing.
- If you're not sure a receipt matches, flag it and ask me.
- Don't delete or rename files without asking.

Output: The spreadsheet updated with a match for each item, plus a list of missing receipts.

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

You'll know it worked when: you can see at a glance what's ready to send and what you still need to find.
