# Category Monitor This skill tracks **one category's aggregate health over time** on **Mercado Livre (Brasil) or Shopee Brasil** — its estimated sales, how many products and sellers it holds, how those sellers split across tiers, and how concentrated the market is. Each run builds **today's snapshot table** for the category and offers it as a **downloadable table**. To see what changed, the user **supplies the 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 default view is the whole category; on Mercado Livre the user may instead point it at a single listing or a catalog product (a catalog product rolls up its competing listings). **Shopee has no catalogue at all**, so that input mode does not exist there. To track one named product over time, use the product-change-monitor skill. For a one-shot opportunity / market-size snapshot, use the category-opportunity-index skill. ## Prerequisites - JoomPulse MCP access is configured for the current agent environment. - The user provides a marketplace — Mercado Livre (Brasil) or Shopee Brasil — and names a category (on Mercado Livre, optionally a single listing or a catalog product instead). - For a period comparison, the user supplies a previous table that this skill produced for the **same category on the same m
