Does it handle Japanese imperial dates like Reiwa and Heisei?

Yes, the skill automatically converts Japanese era names (和暦) into standard Western calendar years (西暦) during the extraction process.

What specific fields can it extract?

It extracts the payer name, total payment amount, withheld tax, social insurance, life and earthquake insurance deductions, and housing loan details.

Can I process multiple tax slips at once?

Yes, you can provide multiple file paths or use patterns, and the skill will process them sequentially and return a consolidated report of the data.

What document formats does this skill support?

The skill supports PDF files as well as image formats like PNG and JPG. For PDFs, it first attempts to extract text directly before falling back to OCR.

How does the dual-verification system work?

To ensure maximum accuracy, the skill can run two independent reading processes in parallel and compare the results. If the results match, the data is accepted; otherwise, it asks the user for clarification.
