product-change-monitor

Monitors how one or a few Mercado Livre products or listings changed over a period — by default week over week. Use it when a user wants to track how a named product changes over time, given a Mercado Livre link, a JoomPulse link, a Mercado Livre listing identifier, or a catalog product identifier. It returns a change table: per product the current value and the difference versus about a week ago for price, rating, and review count, plus the current estimated weekly sales and revenue, logistics, listing type, seller medal, and time on air, with a JoomPulse link per product. Triggers include: "monitor this product", "track price changes", "what changed this week", "did the price drop", and the pt-BR equivalents "monitorar este produto", "acompanhar este anúncio", "o preço caiu", "variação de avaliações". Sales and revenue are JoomPulse estimates, not real transactions; price, rating, and reviews are real history. For point-in-time product and competitor analysis, use the single-product analysis skill.
