Payment Statement Image Reading

Image Reading Methods

Recommended: Dual Verification (Parallel 2 Contexts)

1. Execute two independent readings: In environments where sub-agents are available, launch two sub-agents in parallel and have each read the image independently. Pass the following "Basic Rules" and "Output Format" as prompts to each sub-agent, and specify the image file path.
2. Result Collation: Compare key fields (such as amounts) from both reading results.
3. If results match: Adopt the results as-is. Report "Results matched in two independent readings."
4. If results do not match: Present the original image path and both results to the user, and ask them to select the correct one:

• Clearly indicate the fields with discrepancies
• Provide three options: Adopt A / Adopt B / Manual Input

Fallback (When Sub-Agents Are Not Supported)

1. Read the image file directly using the Read tool
2. Extract data according to the "Basic Rules" and "Output Format" below
3. Present the extraction results to the user and always request visual confirmation

Basic Rules

• Read image files using the Read tool (Claude Vision automatically recognizes images)
• Always return amounts as int (integer in yen). Remove commas and the "yen" character
• Return dates in YYYY-MM-DD format
• Convert Japanese calendar years to Western calendar years (Reiwa 7 → 2025, Reiwa 6 → 2024, Heisei 31 → 2019)
• For unreadable fields, use UNKNOWN (string) or 0 (amount)
• If multiple files are provided, process all in sequence and return the combined results

Output Format

---PAYMENT_STATEMENT_DATA---
payer_name: Payer Name
category: Category (Remuneration/Fee/Contract Money/Prize)
gross_amount: Payment Amount (int)
withholding_tax: Withholding Tax Amount (int)
---END---

Extraction Points

• Prioritize extracting the "Payment Amount" field
• Accurately read the "Withholding Tax Amount" field
• Extract the payer's name
• Confirm the category (one of remuneration, fee, contract money, prize)
• Verify the title "Statement of Payment for Remuneration, Fees, Contract Money, and Prizes"
• If readable, include the payee's information (address and name) for confirmation

Processing Multiple Files

1. Use the Glob tool to retrieve the file list (if a pattern is specified)
2. Read each file in sequence using the Read tool
3. Return the combined results of all files (include the file name before each result)
