categorize-transactions

对未分类的银行交易进行审查和分类，将其与发票进行匹配，并验证簿记条目。当用户想要查看交易、对费用进行分类、记账或核对其银行帐户时使用。

Help the user categorize and organize their bank transactions:

1. **Fetch uncategorized transactions**: Call `search_transactions` to find transactions that need attention. Look for unverified or uncategorized entries.

2. **Smart categorization**: For each transaction, suggest a category based on:
   - The transaction description / reference text
   - The counterparty name
   - The amount and pattern (recurring = likely subscription)
   - Similar past transactions

3. **Update transactions**: Use `categorize_transaction` to assign the correct bookkeeping category (SKR04 chart of accounts for German businesses).

4. **Invoice matching**: When a transaction looks like an incoming payment:
   - Call `list_invoices` to find matching unpaid invoices (by amount or client)
   - Use `link_transaction` to connect the payment to the invoice

5. **Document attachment**: Remind the user to attach receipts for expenses:
   - Use `upload_bulk_attachments` for multiple receipts
   - Use `link_attachment_transaction` to connect receipts to transactions

6. **Verification**: After categorizing, use `change_transaction_verification` to mark transactions as verified.

Present transactions in batches of 10-15 for manageable review. Show: Date, Amount, Description, Suggested Category.

## 中文说明

帮助用户对其银行交易进行分类和整理：

1. **获取未分类交易**：调用 `search_transactions` 查找需要处理的交易。寻找未核验或未分类的条目。

2. **智能分类**：对每笔交易，基于以下信息建议类别：
   - 交易描述 / 备注文本
   - 交易对手方名称
   - 金额和规律（周期性 = 很可能是订阅）
   - 类似的历史交易

3. **更新交易**：使用 `categorize_transaction` 分配正确的簿记类别（面向德国企业的 SKR04 会计科目表）。

4. **发票匹配**：当某笔交易看起来像是一笔收款时：
   - 调用 `list_invoices` 查找匹配的未付发票（按金额或客户）
   - 使用 `link_transaction` 将该收款与发票关联

5. **单据附件**：提醒用户为支出附上收据：
   - 使用 `upload_bulk_attachments` 上传多张收据
   - 使用 `link_attachment_transaction` 将收据与交易关联

6. **核验**：分类完成后，使用 `change_transaction_verification` 将交易标记为已核验。

以每批 10-15 笔的方式呈现交易，以便于审查。显示：日期、金额、描述、建议类别。
