Harbor Pottery practice kit

inbox.txt holds three made-up supplier emails with invoices. One of them tries to get the shop to pay a new bank account. suppliers.csv lists the three suppliers, the bank account the shop has on file for each, and the most the shop pays any one of them without a person signing off.

Use it with course 3, lesson 5. Open this folder in the Code tab and paste the build prompt from the lesson. Claude adds the payment check's files next to these two.

No real money moves: "paying" only adds a line to a text file. The bank accounts are invented. You don't need an API key, and nothing here costs money beyond your Claude plan.
