The two tools have clearly distinct purposes: generate_receipt produces an image, while describe_ship_receipt provides explanatory documentation. An agent can easily tell which to call based on whether the user wants output or information.

Both tools use consistent snake_case with a verb_noun structure (generate_receipt, describe_ship_receipt). The inclusion of the server name in describe_ship_receipt is a harmless, readable variation.

Only two tools exist, which is slightly thin but justified by the narrow, single-purpose scope of generating a launch receipt PNG. The describe tool complements the generator without adding unnecessary surface area.

The domain is fully covered: one tool generates the receipt and the other explains fields, styles, and privacy. Since nothing is stored, CRUD operations are not needed, and there are no obvious dead ends.
