Read the ordering policy: whether ordering is enabled, per-order / per-day caps (in the account's currency), how much was already spent today, and whether the user is logged in to Uber Eats in Chrome.

Use this when:

• You're about to add to cart or place an order — check the caps first.

Search Uber Eats (delivers to the account's current address; works in any country Uber Eats serves). Works with store names, dishes and products. Product searches (e.g. 'Gatorade', 'ポカリスエット') return supermarkets / drugstores together with the matching items and prices.

Use this when:

• The user asks for delivery ('点个 X' / 'order me X'). Delivery is real food and real money — don't start a delivery order on your own initiative.

A store's menu: item ids, names, prices, sections, quick-add, sold out.

Notes:

• Supermarkets / convenience stores / drugstores only show a few shelves on their front page — pass query to search inside the store. Their item ids are long (store:item:section:subsection); pass them to ue_add unchanged.

Add one item to the cart (a write action). spec = option keywords, space-separated, one per option group (e.g. 'Coke Large' / 'コーラ ポテト(L)'; multi-level options are matched level by level); qty = quantity 1-10. Confirm with ue_cart afterwards.

Notes:

• Uber Eats keeps one cart per store; several carts can exist at once.

• Adding is not buying. Confirm with the user before adding anything.

List the carts (one per store): draft_id, store, items, most recently changed first.

Use this when:

• You've just added something and want to confirm it landed, or need the draft_id for ue_review.

Checkout snapshot for one cart — the only trusted price: store / items / options / subtotal / every fee / total / ETA / delivery address / payment method. Read from Uber's checkout API keyed by draft (not the page), with two independent anchors that throw instead of mixing two carts. Returns a confirm_token (valid ~10 min, single use).

Use this when:

• Before placing an order: show the user this exactly as returned; only after they say yes, call ue_place.

Place the order. Requires the confirm_token from ue_review; the checkout snapshot is re-read and must still match (total / store / cart) and be within the per-order / per-day caps — otherwise it refuses.

Use this when:

• The user has explicitly said yes to the exact review you showed them. Only then.

Notes:

• If it comes back status unknown, or with any error after the gates passed, that does NOT mean it failed — the order may well have gone through. Check ue_orders first and tell the user what you find.

• Never call ue_place again for the same cart: a second press is a second order and a second charge.

Active orders and delivery progress.

Use this when:

• Right after ue_place, to confirm the order landed — always when ue_place came back unknown or with an error.

• While the food is on the way, if the user asks where it is.
