Extract key terms from the contracts at [file URL 1], [file URL 2], and [file URL 3], then generate a contract register spreadsheet. Use the extract_document tool with these fields:
- contracts (ARRAY): One entry per contract file, each with:
- contract_title (TEXT): Title or subject of the contract
- counterparty (TEXT): Name of the other contracting party
- effective_date (DATE): Date the contract becomes effective
- expiry_date (DATE): Date the contract expires or ends
- contract_value (CURRENCY_AMOUNT): Total or annual contract value if stated
- currency (CURRENCY_CODE): Currency of contract value
- auto_renewal (BOOLEAN): Whether the contract auto-renews
- governing_law (TEXT): Jurisdiction or governing law
Then use the generate_sheet tool to create an XLSX contract register with the extracted rows.
