Find Exact Same Product

This skill finds listings that appear to represent the same real-world product as a reference product, on Mercado Livre (Brasil) or Shopee Brasil, using JoomPulse market data. The seller picks a marketplace and hands over a reference — a title, a link, an identifier or a picture — and the skill returns the listings it can confirm are the same product, each with a short reason.

"The same product" means the candidate listing matches the reference item's identity: brand, model, variant, color, size, capacity, pack count, bundle contents, and other defining attributes visible from the provided product data. Formatting, casing, punctuation, and translation differences are acceptable when the underlying product is clearly the same.

What confirms that identity differs by marketplace. On Mercado Livre several sellers can list the very same catalogue product, so the shared catalogue is the strongest anchor available. On Shopee nothing links different shops' listings of one product, and an item belongs to a single shop, so a match has to be built from a title search and then confirmed on attributes.

Prerequisites

• JoomPulse MCP access is configured for the current agent environment.
• The user provides a marketplace — Mercado Livre (Brasil) or Shopee Brasil — and a reference product: a title, a product link, a product identifier, or a product image.
• The available JoomPulse tools can search marketplace listings on either marketplace and return enough product data to compare candidates: title, category, price, seller or shop, rating and review count, and, where the marketplace records it, brand.
• The image route needs an image-based product search, which exists on Mercado Livre only.

If JoomPulse MCP access is unavailable, stop and explain that the skill requires JoomPulse MCP setup before it can search or compare products.

Scope

• Mercado Livre (Brasil) and Shopee Brasil, one at a time. Other marketplaces are out of scope.
• What anchors a match differs. On Mercado Livre, the listings of one catalogue product are the reference set. On Shopee there is no shared catalogue identifier linking different sellers' listings of the same product, so that anchor does not exist: matching is a title search plus attribute confirmation.
• A title-only match is not a confirmed match on Shopee. Confirm on brand plus category plus a plausible price band, and label anything weaker as a likely candidate, not a match.
• The photo route is unsupported on Shopee — there is no image-similarity search. Say so plainly instead of attempting it.
• An absent match is not proof the product is not sold on Shopee: coverage includes only items with at least one lifetime sale, and brand is recorded for tracked items only.
• Read-only. The skill does not sign in as the seller or modify any listing.
• Language: detect the seller's language and respond in it. Default to pt-BR.
• Keep the workflow invisible. The seller wants the answer, not a play-by- play. If one approach does not return data, switch to another quietly; only if every approach fails do you say one short, friendly sentence.

Shopee data — what differs from Mercado Livre

• Estimates come from Shopee's own rounded sold counters, refined with review movement. Treat small gaps between items as noise and never rank on a difference of a few units. Price, rating and review count are real.
• Coverage is not a census: only items with at least one lifetime sale are tracked, so any count is a lower bound and an absent item is not evidence it does not sell.
• History starts May 2026 — there is no long-run trend and no seasonal read.
• Category analytics stop at three levels; the item view reaches deeper. Say which you used.
• No seller medals — Shopee has three mutually exclusive shop tiers: Official store, Preferred (Indicado) and Common. There is no ladder; inventing Shopee medals is fabrication.
• No catalogue and no buy-box, and an item belongs to one shop.
• No fulfilment programme, no free-shipping flag and no listing tier — show — rather than guessing.
• Concentration is measured differently and thresholds do not transfer between marketplaces.
• Item titles mix Portuguese, English and Chinese — search both languages.

Workflow

Step 0 — Decide the marketplace

JoomPulse covers two separate marketplaces: Mercado Livre (Brasil) and Shopee Brasil. They are independent datasets with different coverage, history and mechanics. Decide which one the request belongs to before reading any data:

• The seller said so. "Shopee" means Shopee; "Mercado Livre", "MeLi" or "ML" means Mercado Livre.
• An identifier gives it away. An identifier beginning MLB is Mercado Livre; a bare 10–11 digit number is a Shopee item or shop. A mercadolivre.com.br link is Mercado Livre, a shopee.com.br link is Shopee. If an identifier is not found on the marketplace you assumed, check the other one before telling the seller it does not exist.
• The request only makes sense on one of them — buy-box, catalogue position, seller medals, a fulfilment programme or search keywords are Mercado Livre only.
• Otherwise ask — one short question, mentioning that both are available. Never guess and never default.

Never mix data from the two marketplaces in one query, one table or one total. They are separate pipelines with different grains and estimate methods; a combined figure is simply wrong. If the seller wants both, run the analysis twice and report the two side by side, comparing direction and orders of magnitude — never exact numbers.

Step 1 — Resolve the reference product

• If the user provides a title, use it directly as the reference.
• If the user provides a link or an identifier, fetch the available product details first. A Mercado Livre listing code or link resolves on Mercado Livre; a Shopee link carries two bare numeric identifiers — the shop and the item — and resolves on Shopee.
• If the user provides an image:
  • On Mercado Livre, use the available image-based product search workflow to generate candidate listings.
  • On Shopee there is no image-similarity search — say so plainly rather than attempting one. You may still read the picture yourself, describe what you see (brand, product type, colour, pack size) and search on those words, but label the result as a search by your own reading of the photo, never as an image match.
• Echo back what you captured — the marketplace and the reference product — so the user can correct it before you search.

Step 2 — Search for candidate listings

• Use JoomPulse product search to find plausible candidates. Treat search results as candidate generation, not final truth.
• Mercado Livre: start from the listings of the same catalogue product, then widen to a title search inside the category if that set is thin.
• Shopee: title search is a literal substring match, and item titles mix Portuguese, English and Chinese. So:
  • search several short terms instead of one long precise phrase — a long phrase typically returns nothing at all;
  • try both the Portuguese and the English wording of the same term;
  • scope the search to a category, because a short generic term on its own comes back full of unrelated bundles and accessories.
• Prefer a compact candidate set first, then broaden only when recall is clearly too low.

Step 3 — Enrich candidates

• Fetch title, category, price, images, seller or shop, rating, review count, the attributes the marketplace records, and the link for each candidate.
• Mercado Livre: the catalogue product and the listing attributes carry most of the identifying detail.
• Shopee: brand is recorded only for tracked items, so expect it to be missing on part of the set; also check how recently each item was last seen, so a stale row is never presented as a live listing.
• Keep enough source data to explain why a candidate was accepted or rejected.

Step 4 — Decide the matches

• Accept a candidate only when the defining attributes match the reference.
• Reject candidates when brand, model, size, color, capacity, pack count, bundle contents, or other defining attributes differ.
• On Shopee, confirm a match on brand plus category plus a plausible price band — never on the title alone. A title-only match is not a confirmed match: report it as a likely candidate and say what is still unverified. Where brand is absent, a likely candidate is the strongest claim available.
• If data is insufficient for a confident match, do not mark it as exact.
• Do not rely on title similarity alone when important attributes are missing or ambiguous.

Step 5 — Return the results

• List confirmed matches with their links — the JoomPulse page on Mercado Livre, the item's own Shopee link on Shopee. There is no JoomPulse dashboard link for Shopee rows, so never invent one.
• Include a short rationale for each accepted match.
• If there are no confident matches, say so clearly and summarize what was checked, including which wordings were tried. On Shopee, add that this is not proof the product is not sold there — coverage includes only items with at least one lifetime sale.
• When useful, include rejected near-matches separately with the key reason they were rejected.

Output Format

Respond in the seller's language. Lead with a short line naming the marketplace and the reference product. Use a concise table when there are multiple candidates:

Result	Product	Link	Why it matches
Match	Product title	Product link	Same brand, model, size, and variant

• Mercado Livre: the product column carries the listing code, and the link points at its JoomPulse page.
• Shopee: the product column carries the item title and its shop, and the link is the item's own Shopee link, built from the two numeric identifiers for the shop and the item. A row is a Match only when brand, category and price band agree; otherwise call it a likely candidate and name what is still unverified.

For a single match, a short paragraph with the product link and rationale is enough. Empty field → —; never guess or fabricate.

Notes

• Prefer precision over recall. A smaller list of confident matches is better than a broad list of uncertain candidates.
• Do not expose raw private data, internal identifiers, or implementation details in the final answer.
• If the user asks for bulk matching, process items one by one and make uncertainty explicit for each item.
• Never mix the two marketplaces in one table. If the seller wants to know whether a Mercado Livre product is also on Shopee, run the search twice and report the two sides separately.
• No image-similarity search on Shopee: say so in one short sentence and offer a term search based on your own reading of the photo instead. Never imply a photo match was performed.
• Nothing found on Shopee: an empty result is a floor, not a verdict — coverage includes only items with at least one lifetime sale, and a literal title search misses the wordings you did not try. Offer to try other terms or another category.
• Market data temporarily unavailable: retry once quietly; if it is still down, say market data is temporarily unavailable and to try again shortly. Never paste internal error text, HTTP codes, or field names to the seller.
