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: Find my business expenses in this year's bank statements and organize them into a categorized spreadsheet.

Quick check first: Which accounts are business, and are any personal?

What I need from you:
- Your bank statements for the year (all accounts)
- Any categories your accountant uses

Rules:
- Pull out business expenses and categorize them.
- Ask me about anything that could be personal or business.
- Don't change the original files.

Output: A spreadsheet of business expenses by category, plus a list of items to check.

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 have a clean expense list ready for taxes, with only a few items to correct.
