What the hardware does

A custom network bridge prints actual labels and packing slips across two warehouses.

How the agent helped

Ryan Kulp's firsthand rollout says 'to actually write the code we used Claude (CLI) and the Superpowers skill'; its final-product section identifies the Swift printer utility and shows the shipping station used in the deployed system.
