Turn customer order emails into ready-to-enter orders with a reader agent and a separate checker: pull out every line, check it against your price list and stock, and send only the exceptions to a person: AI agent prompt

Help me turn customer order emails into clean orders, with a second check before anything is entered. My setup: [what we sell, how orders arrive (email body, PDF, spreadsheet, photo), the system we enter them in]. My reference data: [paste product list with SKUs, units and prices, customer list with account numbers and delivery addresses]. For each order I paste [paste order email and attachments]: 1) Reader step: extract customer, account number, delivery address and date, PO number, and every line (product as written, matched SKU, quantity, unit, price). Show how sure you are of each SKU match. 2) Checker step: re-read the original email and check the extraction line by line: wrong or unmatched SKUs, unit mix-ups (cases vs single items), prices that differ from my list, missing PO or delivery date, duplicate orders, unusual quantities compared with this customer's normal orders. 3) Output: a ready-to-enter order table, a list of exceptions with the exact question to ask the customer, and a short reply email confirming the order or asking for what's missing. Mark the order 'ready' only if the checker found no issues; otherwise 'needs a person'. Don't send anything or enter orders yourself.
