Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00222 | $0.04980 |
| Opus 5 | $0.00111 | $0.02490 |
| Sonnet 5 | $0.00044 | $0.00996 |
| Haiku 4.5 | $0.00022 | $0.00498 |
Grade A, and why
uncontested-niche-finder 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 6d 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.
How it starts
The opening of the file, as written. The whole thing — 384 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Uncontested Niche Finder
This skill finds products in deep sub-categories of a chosen category — on Mercado Livre (Brasil) or Shopee Brasil — where the whole deep sub-category has no dominant incumbent among its listings. On Mercado Livre the incumbent test is no platinum seller at all; on Shopee, which has no seller medals, it is no Official store (Shopee Mall) seller at all. Given a marketplace and a category by name or identifier, it surfaces the active listings in those deep niches, and ranks them by estimated traction so the strongest uncontested opportunities surface first. On Mercado Livre each row links to its JoomPulse page; on Shopee each row links to the item on Shopee.
A truly uncontested niche is a whole deep sub-category with zero incumbents of that kind — not merely the listings without one inside a sub-category that still has them elsewhere. Dropping individual incumbent-held listings is not enough: if any platinum seller (Mercado Livre) or any Official store (Shopee) is active in the sub-category, that niche is contested, so the skill keeps only the deep sub-categories with none present. If keeping only those would leave too few results, the skill may also show the non-incumbent listings from sub-categories that still have one — but it labels those plainly as non-platinum listings (platinum sellers still present in the category) on Mercado Livre, or listings outside an Official store (Official stores still present in the category) on Shopee, and does not call them uncontested.
This is different from broad assortment work. To size up one product and the products that compete with it, use the ml-product-analysis skill. To find the fast-growing deep categories under a category (rather than the products inside them), use the growing-leaf-category-tracker skill. This skill answers "where can I enter without facing a dominant incumbent?" for a category the seller names, on the marketplace they choose.
Prerequisites
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.

uncontested-niche-finder is a skill published in the GitHub repository joomcode/joompulse-skills (50 stars, last pushed 16d ago), licensed MIT. It adds 222 tokens to every session and 4,980 once invoked, about $0.0011 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
