Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

top-sellers-in-category scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Top Sellers In Category

This skill returns the top sellers in one Mercado Livre (Brasil) category, ranked by estimated average monthly revenue. For each seller it shows estimated average monthly sales and revenue, completed sales over the last 365 days, cancellation rate, sales trend, brands, how their products split between all listings and listings with sales, international shipping, and classic versus premium listing counts.

By default it produces today's leaderboard as a downloadable table. It can also show how the ranking moved over time: if you supply a previous-period leaderboard that this skill produced for the same category, it compares the two and reports each seller's movement (rose / fell / new) plus the biggest movers. The baseline is the table you supply — there is no hidden session memory.

To monitor a single named seller over time, use the seller-overview-tracker skill. To rank brands rather than sellers, use the top-brand-position-tracker skill.

Prerequisites

  • JoomPulse MCP access is configured for the current agent environment.
  • The user names a category (free text is fine).
  • For a period comparison, the user supplies a previous leaderboard that this skill produced for the same category (pasted or uploaded). Without it, the skill produces a standalone leaderboard.
  • The available JoomPulse tools can find the sellers active in a category and return each seller's profile (estimated average monthly sales and revenue, last-365-day completed sales, cancellation rate, sales trend, brands, listing distribution, international shipping, classic and premium listing counts). Seller medal — used to color the chart — and reputation are read when available.

If JoomPulse MCP access is unavailable, stop and explain that the skill requires JoomPulse MCP setup before it can rank a category's sellers.

Scope

  • Mercado Livre (Brasil) only. Other marketplaces are out of scope.
  • Sales and revenue are JoomPulse estimates derived from historical listing data — not real transactions. Cancellation rate and last-365-day completed sales are real history. Disclose the estimate caveat in every output.
  • Read-only. The skill never writes or modifies anything; it does not store the leaderboard — the user keeps the downloadable table and brings it back next period.
  • Language: detect the seller's language and respond in it. Default to pt-BR.
  • The baseline is user-supplied. Never claim a movement without a previous leaderboard to compare against, and never infer or fabricate one from memory.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
