Receipt, Payment Receipt, Furusato Nozei Donation Receipt Image Reading

Image Reading Methods

Recommended: Dual Verification (Parallel Two Contexts)

1. Execute two independent readings: In an environment where sub-agents are available, launch two sub-agents in parallel to 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 amount) from both reading results.
3. If results match: Adopt the result 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 fields with discrepancies
• Offer 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 eras to Western calendar (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 order and return the combined results

• Use the transaction date on the receipt (not the issue date) as the date

• Extract the official name of the municipality (e.g., "XX City", "XX Town", "XX Village")
• The prefecture name is often stated before the municipality name
• Extract the donation amount from the "Amount" or "Donation Amount" field
• Use the donation receipt date as the date
• Extract the receipt certificate number from notations like "No. XX"
