Most tools target distinct operations (search, view, add, bulk add, status, checkout link), but remove_from_cart is fully redundant with update_cart_line when quantity is set to 0, creating a blurred boundary for deletion. Descriptions do clarify the intent, which keeps the overlap from being harmful, but two paths to the same outcome remain.

Nearly all names follow a snake_case verb_noun or verb_object pattern (add_to_cart, add_many_to_cart, update_cart_line, remove_from_cart, view_cart, search_products), with checkout_link as a noun-ish compound and status as a bare noun outlier. The pattern is predictable and readable despite those two deviations.

Eight tools map cleanly onto the cart workflow: discover, inspect, mutate (single/bulk/update/remove), finalize, and check session state. Nothing feels bloated, and each tool except the redundant remove_from_cart earns its place.

The core lifecycle is covered end-to-end: search products, add single or many, view cart, adjust quantity, remove lines, and obtain a checkout link for manual payment. Minor gaps exist (no clear-cart operation, no product-detail endpoint beyond search, no order history), but agents can work around them by removing lines individually.
