## 原文

Help the user find and attach receipts to their transactions:

## Step 1: Identify transactions missing receipts
- Call `search_transactions` to find recent transactions
- Call `list_attachments` to check which transactions already have receipts attached
- Present a list of transactions that are missing receipts, sorted by amount (largest first)

## Step 2: Search for receipts
Guide the user to find receipts from various sources:

**Gmail / Email:**
- Suggest searching Gmail with queries like:
  - `from:{vendor} subject:receipt` or `from:{vendor} subject:invoice`
  - `subject:Rechnung from:{vendor}`
  - `subject:Bestellbestätigung` (order confirmation)
  - `has:attachment after:{date} {vendor name}`
- For common vendors, suggest specific search terms:
  - AWS: `from:aws subject:"invoice available"`
  - Google: `from:payments-noreply@google.com`
  - Apple: `from:apple subject:receipt`
  - Amazon: `from:auto-confirm@amazon subject:Bestellung`

**Other sources:**
- Check vendor portals (suggest logging into the vendor's website to download invoices)
- Check cloud storage (Google Drive, Dropbox) for scanned receipts
- Check photo library for photos of paper receipts

## Step 3: Upload and attach
Once the user has the receipt files:
- Use `upload_bulk_attachments` to upload multiple receipts at once
- Use `create_attachment` for individual receipts with metadata (vendor, date, amount)
- Use `link_attachment_transaction` to connect each receipt to its matching transaction

## Step 4: Verify
- After attaching, use `change_transaction_verification` to mark transactions as verified
- Show a summary: how many receipts were found, attached, and how many are still missing

Tips:
- In Germany, receipts must be kept for 10 years (Aufbewahrungspflicht)
- Digital copies are legally accepted (GoBD-compliant) when stored properly
- Prioritize receipts for expenses over 250 EUR (required for Vorsteuerabzug)
