La Medicina Tienda de cultivo

• Add To Cart — Add a product to the shopper's cart, which updates on screen immediately. A variant id names what to add on its own; otherwise, for a product with variants, pass the option value ids from get_product's "options" - and if the shopper has not chosen yet, ask them, or call show_variant to show one first. Adding does not start checkout - use proceed_to_checkout when they are ready to pay.
• Apply Coupon — Apply a discount coupon code to the cart and report the resulting total.
• Browse Store — Browse the store the way a shopper would. Called with no arguments it lists the categories the merchant features in the store navigation; called with a category permalink it lists that category's products, with name, price and a link. Stock is not included here - call get_product before adding anything from a category listing. Use it when the shopper is exploring rather than looking for something specific.
• Cancel Cart — Empty the shopper's cart, removing every item and any coupon. ALWAYS confirm with the shopper first: this discards everything they chose and cannot be undone. To remove a single line use update_cart_item with qty 0 instead.
• Estimate Shipping — What the store can ship to a destination and what it costs, for the cart as it stands. Ask for it when the shopper wants to know the delivery cost or time before they check out - it is the question that most often decides whether they finish. Needs a country and a region; a postal code makes the estimate exact where the store charges by it.
• Get Cart — Read the shopper's current cart: line items, quantities, discounts, shipping and total. This is the same cart shown on screen, so read it before answering anything about what they are buying rather than relying on what was said earlier in the conversation.
• Get Product — Get one product's details, OR open it in the browser. Returns description, price, stock, and for a product with variants every option and the values it accepts under "options" - not the combinations themselves; use show_variant for a specific one. Set navigate=true when the shopper wants to SEE the product ("show me", "open", "view", "take me to"). Leave it false, the default, when you need data to answer a question or to prepare an add_to_cart - the browser then stays where it is. Does NOT add
• Get Recommended Products — Products this store recommends alongside what is already in the cart. Use it to suggest genuinely related items before checkout.
• Proceed To Checkout — Open checkout so the shopper can review and pay. Use it when they say they are done. You CANNOT place the order or enter payment details, and no tool here can: the shopper completes the purchase themselves. Once this returns, stop - do not navigate again and do not tell them the order was placed.
• Search Catalog — Search this store's catalogue by keyword. Returns name, price, stock and a link for each match. Use this FIRST whenever the shopper names something specific they want. It does not open anything or change the cart: call get_product for detail, add_to_cart to buy.
• Show Variant — Show one specific variant of a product on the page, chosen by its option values, and report its price and stock. Opens the product page with that variant selected, so the shopper sees what is being discussed. Use it after get_product to resolve a combination.
• Update Cart Item — Change the quantity of a line already in the cart, or remove it by setting the quantity to 0. Use the cart_item_id from get_cart, not the product id.
