# Product Change Monitor This skill shows how **one** product — or a few of them — **changed over a period**, by default the last week, on **Mercado Livre (Brasil) or Shopee Brasil**, using JoomPulse market data. Given a product by a marketplace link, a JoomPulse link, or a listing, item or catalog product identifier, it reports for each product the current value **and the change versus about a week ago** for the metrics that have real history (price, rating, review count), plus the current snapshot for estimated sales and revenue, how long the listing has been on air, and the seller and logistics attributes that marketplace actually has. The result is a change table plus a downloadable spreadsheet; on Mercado Livre each row links to its JoomPulse page, on Shopee each row links to the item on Shopee. This is different from a single point-in-time analysis. To size up a product and find the products that compete with it, use the single-product analysis skill. To decide which new products to add across a whole catalog, use the gap-analysis skill. This skill answers "how did this product move over time?" for a product the user names. ## Prerequisites - JoomPulse MCP access is configured for the current agent environment. - The user provides a marketplace — Mercado Livre (Brasil) or Shopee Brasil — and one product (or a small set) as a marketplace link, a JoomPulse link, or a listing, item or catalog product identifier. - The available JoomPulse tools can look up a product
