Workflow (MANDATORY)
Step 1: Collect Invoice Data
Accept input in any of these forms:
- Images: Read invoice photos using the Read tool. Extract: date, vendor, amount, item type, notes.
- Text descriptions: Parse the user's text for the same fields.
- Mixed: Multiple images + supplementary text.
For each invoice, extract these fields:
{
"date": "2026-04-15",
"vendor": "海底捞(国贸店)",
"item": "客户餐费",
"amount": 486.00,
"category": "业务招待",
"note": "与XX公司李总晚餐"
}Step 2: Classify
Assign each invoice to a category from the table above. Rules:
- If the user explicitly states the category, use it.
- If the item/vendor clearly matches a category keyword, auto-assign.
- For ambiguous items (e.g., "餐费" could be 业务招待 or 差旅-餐饮):
- If the note mentions a client/customer → 业务招待 - If the context is a business trip → 差旅-餐饮 - If unclear, ask the user.
Step 3: Confirm with User
Before generating, show the extracted data as a table:
| # | 日期 | 商户 | 项目 | 金额 | 分类 | 备注 |
|---|------|------|------|------|------|------|
| 1 | 2026-04-15 | 海底捞 | 客户餐费 | 486.00 | 业务招待 | 与XX公司李总 |
| 2 | 2026-04-14 | 滴滴出行 | 打车 | 45.50 | 差旅-交通 | 机场→酒店 |Ask: "以上信息是否正确? 需要修改或补充吗?"
Step 4: Generate Excel
Write the confirmed data to a temp JSON file, then run:
python expense-report-skill/scripts/generate_report.py \
--input /tmp/invoices.json \
--output "发票报销汇总-YYYYMMDD.xlsx"JSON format (array of objects):
[
{"date": "2026-04-15", "vendor": "海底捞", "item": "客户餐费", "amount": 486.0, "category": "业务招待", "note": "与XX公司李总"},
{"date": "2026-04-14", "vendor": "滴滴出行", "item": "打车", "amount": 45.5, "category": "差旅-交通", "note": "机场→酒店"}
]Step 5: Deliver
Tell the user:
- Output file path
- Total amount and breakdown by category
- Remind them to review the "分类汇总" sheet for the summary
Output Format
The Excel file contains two sheets:
- 发票报销汇总 — Full detail, grouped by category with subtotals
- 分类汇总 — Summary table: category, count, subtotal
Style: Lovstudio warm-academic (terracotta headers #CC785C, warm cream accents).
Edge Cases
- Blurry/unreadable image: Tell the user which fields couldn't be extracted; ask them to provide manually.
- Foreign currency: Note the currency; convert to CNY if user provides rate, otherwise keep original with note.
- Duplicate invoices: Flag potential duplicates (same date + vendor + amount) before generating.
- No date on invoice: Use the date the user provides, or mark as "日期不详".
