To see what changed, the user **supplies the seller's table from a previous period** (the one this skill produced before); the skill compares the two and shows the difference per metric. **The baseline is whatever table the user provides — there is no hidden session memory and nothing is stored server-side.** The seller is identified by a store link or a seller identifier on either marketplace. It is different from ranking work: to rank many sellers in a category and track how that ranking moves, use the top-sellers-in-category skill; to analyze one product, use the single-product analysis skill. This skill follows **one** seller. ## Prerequisites - JoomPulse MCP access is configured for the current agent environment. - The user provides a marketplace — Mercado Livre (Brasil) or Shopee Brasil — and one seller as a store link or a seller identifier on that marketplace. - For a perio
