## What it does

This skill walks an agent through the VTEX External Seller protocol on the seller host: answering simulation calls during indexation and checkout, then booking a reservation for each new order and committing it after approval. Once goods ship, the seller calls the marketplace OMS to report invoices and tracking.

The simulation endpoint gets 2.5 seconds; miss that and the offer counts as unavailable. OMS URLs take the marketplace order id. Use the reservation id you returned as `orderId` and the invoice never reaches the customer's order. An `Output` invoice records a sale, an `Input` one a return, and an invoiced order can only be canceled after a return invoice.

Tracking goes in later through a separate `PATCH`, once the carrier supplies it. Split shipments get one invoice per package, with `invoiceValue` summed over that package's items only. Catalog sync and order feed handling live in `marketplace-catalog-sync` and `marketplace-order-hook`, not here.

## When to use it
- answer VTEX simulation calls with shipping options and stock within 2.5 seconds
- create a reservation on order placement and return its id as `orderId`
- turn a reservation into a firm order on the `fulfill` call
- post invoices and tracking to OMS under the marketplace order id
- issue a separate invoice for each package of a split shipment

## Example prompts
- Write a `POST /pvt/orderForms/simulation` handler for a VTEX External Seller that replies inside 2.5 seconds
- Build `POST /pvt/orders` so it creates a reservation, and add the `/fulfill` handler for our seller service
- Send the OMS invoice for this order, then update tracking with a `PATCH` once the carrier gives us a code
