Check whether there is an active Lufa Farms session.

This makes a live request rather than just checking for a saved cookie. If a note field is present, the session cookie exists but its validity couldn't be fully confirmed (see the note text for why) — tool calls may still work, or may come back asking for a re-login.

Log out from Lufa Farms and erase the saved session from disk.

Retrieve the full product catalog for the current order week.

Returns product IDs, names, prices, producers, and category tags. Requires an active session.

Search the Lufa Farms marketplace by keyword.

Use this to quickly locate a specific item without loading the full catalog.

Args: query: Search term, e.g. "heirloom tomatoes", "sourdough bread", "goat cheese".

Get detailed information for a specific product.

Returns name, price, producer, category, weight, and organic status, looked up from the full marketplace catalog.

Args: product_id: Product ID from lufa_get_products or lufa_search_products.

Retrieve the nutritional information panel for a product.

Returns calories, macronutrients, and ingredient list.

Args: product_id: Product ID to look up.

Show the current basket contents.

Returns all items, quantities, unit prices, and the running order total. Requires an active session.

Add a product to the basket. Changes take effect immediately (there is no separate draft state) — verified live: basket total updated right after the call, with no save_basket needed to see it reflected.

Products that come in multiple sizes/formats (e.g. "family format") are listed as separate product IDs, not a weight variant of the same product — check the sub_products field from lufa_get_product_details to find them, then add the desired variant's ID directly. Requires an active session.

Args: product_id: Product ID to add. quantity: Number of units to add on top of the current basket quantity (default 1). This is an increment, not an absolute target quantity.

Remove a quantity of a product from the basket.

Requires an active session.

Args: product_id: Product ID to remove. quantity: Number of units to remove (default 1). Pass a value >= the current basket quantity to remove the line entirely.

Not required for normal use — kept only for backwards compatibility.

lufa_add_to_basket / lufa_remove_from_basket already persist to the server immediately; there is no "confirm order" step anywhere in Lufa's actual site (no such button or endpoint exists in the marketplace frontend). This calls a legacy per-product endpoint with no product specified, which is effectively a no-op that returns success trivially. Requires an active session.

Add or remove a product from the user's favorites list.

Favorites appear prominently in the marketplace next week, making it easy to reorder frequently purchased items. Requires an active session.

Args: product_id: Product ID to favorite/unfavorite. favorite: True to add to favorites, False to remove (default True).

Show the current or upcoming order summary.

Returns the delivery date, pickup location, basket breakdown, and final totals. Requires an active session.

Retrieve delivery metadata for the current order, including a countdown.

Returns the delivery date, address, and delivery time window, plus two computed fields: delivery_window_starts_at (ISO timestamp) and time_until_delivery (e.g. "3d 22h") — how long until the delivery window opens. Lufa's API doesn't expose an explicit order-cutoff field, so treat this as a useful approximation of how much time is left, not a confirmed deadline — Lufa may stop accepting basket changes some time before the delivery window actually opens. Requires an active session.
