Finds products with no brand (unbranded / no-name / generic) in one category on
JoomPulse — Mercado Livre (Brasil) or Shopee Brasil: an opening for your own brand
/ private label, where buyers aren't brand-anchored. Asks for a marketplace and a
category, ranks the no-brand listings by estimated demand, and returns a product
table. Triggers: "unbranded products", "products without a
brand", "private-label opportunities", "unbranded products on Shopee"; pt-BR
"produtos sem marca", "genéricos que vendem", "oportunidade de marca própria",
"produtos sem marca na Shopee". Ask which marketplace when unclear; never mix the
two. Sales and revenue are JoomPulse estimates, not real transactions; price,
rating and reviews are real. On Shopee the unbranded set is a lower bound. NOT for
ranking brands (use top-brand-position-tracker), new listings (use
new-growing-products-in-category), high-demand low-rated products (use
high-demand-low-quality-finder), or niches without platinum sellers (use
uncontested-niche-finder).

# Unbranded Products In Category
This skill surfaces the **products that have no brand** (unbranded / no-name /
generic) in one category on **Mercado Livre (Brasil) or Shopee Brasil** — the
listings where no brand is attached. These are spots where a seller can enter with
their **own brand / private label**, because buyers there aren't anchored to a
brand name. For each it shows price, estimated sales and revenue, rating, reviews,
time on air, and the seller's or shop's standing. On Mercado Livre each row links
to its JoomPulse page; on Shopee each row links to the item on Shopee.
It is the opposite of ranking a category's brands (for that, use the
top-brand-position-tracker skill). For fresh listings use the
new-growing-products-in-category skill; for low-rated, well-selling products use
the high-demand-low-quality-finder skill; for deep niches without platinum sellers
use the uncontested-niche-finder 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 (free text is fine).
- The available JoomPulse tools can return the listings in a category and resolve a
category name on **either** marketplace, tell which listings have no brand
attached, and provide each listing's price, estimated sales and revenue, rating,
reviews, and time on air. On Mercado Livre they also report listing status,
logistics, listing type and the seller medal; on Shopee, the shop tier, the date
the item was created and the date it was last seen.
If JoomPulse MCP access is unavailable, stop and explain that the skill requires
JoomPulse MCP setup before it can find unbranded products.
## Scope
- **Mercado Livre (Brasil) and Shopee Brasil**, one at a time. Other marketplaces
are out of scope.
- **Sales and revenue are JoomPulse estimates** — not real transactions. By
contrast, price, rating, and review count are real history. Disclose the estimate
caveat 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, and does not render
product images.
- **Language:** detect the seller's language and respond in it. Default to pt-BR.
- **Keep the workflow invisible.** Show `—` for any missing value; never fabricate.
**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 category
Ask for a category if none was given, then use JoomPulse to match the free text to
a category **on the chosen marketplace**. If several plausible matches come back,
list the top candidates (name and depth level) and let the user choose — do not
guess between unrelated categories. On Shopee, category analytics stop at three
levels — if the seller names a deeper niche, work it through the item view instead
and say which you used.
### Step 2 — Find the unbranded products
Use JoomPulse to get the category's listings that have **no brand attached** (brand
empty / unbranded), rank them by estimated demand, highest first, and keep the
strongest ~20–30.
- **Mercado Livre:** take the **active** listings and rank by estimated weekly
demand (estimated weekly revenue, or weekly sales).
- **Shopee:** items carry an explicit "has a brand attached" signal, so the no-brand
filter ports over directly. There is no listing-status filter here — how recently
an item was last seen is what tells you whether it is still live, so check it and
never present a stale row as a live opportunity. Estimated sales and revenue cover
the **last 30 days**, not a week, so rank by estimated 30-day revenue and label
those columns as 30 days.
- **On Shopee the unbranded set is a lower bound.** Brand information exists only
for items that are tracked at all, and only items with at least one lifetime sale
are tracked. Never quote the count or the share of unbranded items as complete,
and never claim that some percentage of the category has no brand.
## Output
Respond in the seller's language (default pt-BR). Lead with a one-line summary (the
**marketplace**, the category and how many unbranded products were found), sort by
estimated demand, and end with the disclaimer. The product list always renders as a
markdown table.
**Product table (Mercado Livre):**
| MLB | Nome | Vendedor | Preço | Vendas (semana) | Receita (semana) | Classificação | Avaliações | Tempo no ar | Frete grátis | Mercado Envios Full | Tipo de anúncio | Medalha do vendor |
|---|---|---|--:|--:|--:|--:|--:|--:|:--:|:--:|---|---|
- The **MLB** identifier links to the item's JoomPulse page.
**Product table (Shopee)** — same shape, with the marketplace's own columns:
| Item | Nome | Loja | Preço | Vendas (30 dias) | Receita (30 dias) | Classificação | Avaliações | Tempo no ar | Nível da loja |
|---|---|---|--:|--:|--:|--:|--:|--:|---|
- The item identifier links to the item on Shopee — **there is no JoomPulse
dashboard link for Shopee rows**, so never invent one.
- **Tempo no ar** is computed from the date the item was created.
- **Nível da loja** is the shop tier — Official store / Preferred (Indicado) /
Common. Never map a shop tier onto a seller medal.
- Free shipping, Mercado Envios Full and the listing tier have **no Shopee
equivalent**: either drop those columns or show `—` in them, never a "Não".
- The sales window differs: weekly on Mercado Livre, 30 days on Shopee. Never
present a 30-day figure under a weekly heading.
- Say in the text that the Shopee list is a **lower bound** — a brand is recorded
only for tracked items, and only items with at least one lifetime sale are
tracked — so it is not the complete set of unbranded items in the category, and no
share of the category can be claimed from it.
**Disclaimer (every report) — use the variant for the marketplace you queried.**

## Visualization
**Render the visuals every time the data supports them.** As soon as the analysis
is done, present the cards and charts described below as a **self-contained visual
panel** — an artifact where the client renders artifacts, an inline widget where
it renders widgets. Do not ask permission first, do not describe the panel instead
of drawing it, and do not offer it as an optional extra: the cards and charts are
part of the answer, not a follow-up.
- **Order:** the cards first, then the charts, then the written read.
- **The data table always stays markdown in the response text**, never inside the
panel — the panel carries cards and charts only.
- **The estimate disclaimer always stays in the response text** as well.
- **Skip an individual chart when its own data threshold is not met** (each
threshold is stated below): a chart nobody can read is worse than no chart.
Skipping one chart never means skipping the panel.
- **Only the cards and charts specified below.** Do not invent extra ones, and do
not promote a categorical value to a bar — a chip or plain text is the honest
rendering for it.
- **If no visual surface is available at all**, fall back to the markdown table
plus the same figures written as text cards. Never block on visuals, and never
leave the answer without its numbers.
The panel contains:
- **Three cards:** number of unbranded products found — on Shopee label it as a
lower bound — total estimated sales for the window in use, and average ticket.
- **A horizontal bar** of the top ~10 unbranded products by estimated revenue —
weekly on Mercado Livre, 30-day on Shopee; name the window on the chart. Render
the chart only when there are enough products (skip it under about four), and
never block on it.
Presentation rules: no product images; render a chart only when the data supports
it; any column with movement uses a word header, never a bare "Δ". The medal palette
(platina = purple, ouro = amber, prata = blue, sem medalha = white with a thin
border) is Mercado Livre only — on Shopee write the shop tier as plain text and
never colour it as if it were a rung on a ladder.
## Notes & Guardrails
The seller should never see a system or stack error — only a friendly next step.
- **No unbranded products in the category:** the category may be brand-dominated —
say so plainly and suggest a broader or adjacent category. Never fabricate rows.
On Shopee, add that the list is a lower bound — a brand is recorded only for
tracked items, and only items with at least one lifetime sale are tracked — so an
empty result is not proof that the whole category is branded.
- **Ambiguous category name:** list the candidates and ask the user to choose. If
nothing matches, check the other marketplace before saying it does not exist.
- **Market data temporarily unavailable:** retry once quietly; if it is still
down, say market data is temporarily unavailable and to try again. Never paste
internal error text, HTTP codes, or field names to the seller.
- **Never silently limit coverage** — if the category is larger than what you
pulled, say the table covers the strongest unbranded products, not all of them.
On Shopee say it twice over: the coverage itself is partial.
