Return the Ametller Origen shopping playbook: how to present products (ALWAYS as a photo-grid artifact), fill and review the real cart, and reorder past shops. Call this once at the start of any Ametller task — before searching or adding to the cart — and follow it.

Check whether the Ametller Origen session is valid.

Open a browser window to sign in to Ametller Origen. The user logs in (and handles any 2FA); the session is then saved so all other tools work. Call this when not signed in, or when a tool reports the session expired.

Find a product and its id (needed before ametller_add_to_cart). Use a short term; Catalan works best (e.g. 'llet', 'pa'). Returns matches with ids and prices.

Get details for a single product by id.

Show the current real shopping cart (items, quantities, total).

List past online orders (date, total, status, item count), by page or as the full bounded history.

List the products in a past order (without adding anything). Defaults to the most recent order if order_id is omitted.

Add a product to the real cart by id (get the id from ametller_search_products first). If already present, increases the quantity. Returns the updated cart with its total.

Set the exact quantity of a product in the cart. Quantity 0 removes it. Returns the updated cart.

Remove a product from the cart entirely. Returns the updated cart.

Add all items from a past order to the cart in one step (a 'buy again'). Defaults to the most recent order. Returns the updated cart.
