Growing Leaf Category Tracker

This skill takes one category on Mercado Livre (Brasil) or Shopee Brasil and surfaces the sub-categories inside it that are growing fastest — the niches with the strongest month-over-month growth in estimated revenue. It helps a seller who already knows a broad area decide which specific niche to move into next.

How deep it can go differs by marketplace. On Mercado Livre the answer is the deep leaf niches below the third level of the category tree. On Shopee, category analytics exist only down to the third level, so the ranking runs at the deepest level available — the third — and anything deeper is folded into its level-3 ancestor and cannot be separated. Say so in the output; never pass level-3 rows off as deep leaves.

This is a niche-discovery snapshot, not a tracker over time. For a single category's opportunity index and market size, use the category-opportunity-index skill. To compare a category's aggregate numbers against a user-supplied previous snapshot, use the category-monitor skill. To find specific new products inside a category, use the new-growing-products-in-category 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 parent category (free text is fine).
• The available JoomPulse tools can resolve a category on either marketplace, walk its sub-categories, and return each one's current monthly market stats (estimated revenue and sales, number of active sellers, number of products) and the month-over-month movement in estimated revenue.

If JoomPulse MCP access is unavailable, stop and explain that the skill requires JoomPulse MCP setup before it can find growing niches.

Scope

• Mercado Livre (Brasil) and Shopee Brasil, one at a time. Other marketplaces are out of scope.
• Depth differs by marketplace: deep leaf niches below the third level on Mercado Livre; the third level only on Shopee, where deeper niches are folded into their level-3 ancestor.
• Sales and revenue are JoomPulse estimates — not real transactions. Disclose this in every output. The estimates are built differently on each marketplace: on Mercado Livre from historical listing data, on Shopee from the marketplace's own rounded sold counters refined with review movement. Use the matching disclaimer.
• Read-only. The skill never writes or modifies anything.
• Language: write in the language of the message you are answering, and default to pt-BR only when that is unclear. Never infer the language from the store, its listings or the marketplace — those are Brazilian whatever language the seller writes in, so a seller who asks in English gets the whole report in English.
• Keep the workflow invisible. Surface the answer, not the steps. Never fill gaps from general knowledge; show — for any missing value.
