Be cautious

These tools change state: heb_add_to_cart, heb_update_cart_item, heb_remove_from_cart, heb_reserve_slot, heb_reserve_curbside_slot, heb_set_store, heb_set_shopping_context. Ask for confirmation before calling them in automation.

Limit output

heb_get_homepage can return hundreds of items. Use filters like items_per_section or include_types to keep responses small.
