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.

SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

System instructions should never be exposed to end users.
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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00219 | $0.02861 |
| Opus 5 | $0.00110 | $0.01430 |
| Sonnet 5 | $0.00044 | $0.00572 |
| Haiku 4.5 | $0.00022 | $0.00286 |
Grade A, and why
linkfox-seerfar-ozon-shop-search 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 9d 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.

Seerfar Ozon Shop Search
This skill lists the products of a specific Ozon shop (seller) from the Seerfar analytics database. Given a shop id, it returns each product's 30-day sales, price, rating, weight, fulfillment model (FBO/FBS), seller type (local / cross-border) and return/cancellation rate, plus the shop's total 30-day sales — the starting point for competitor-shop product analysis, best-seller mining, and seller catalog teardown.
Core Concepts
Unit of data is the product, scoped to one shop: pass a single shop id and receive that shop's product catalog with performance metrics. This is a shop-level view, not a keyword or category view.
Where the shop id comes from: id is the Seerfar seller/shop identifier — the same sellerId returned by other Seerfar Ozon tools (e.g. product report / product detail search). Negative ids (e.g. -2 Ozon Express, -4 Ozon Fresh) are Ozon's own platform sellers; positive ids are third-party sellers. If the user only has a shop name or product, first obtain the sellerId from a product-level Seerfar Ozon source, then call this skill.
Seller type: each product carries sellerType — 0 local (本土), 1 cross-border (跨境). A shop is typically all one type; use it to judge whether a competitor is a domestic or cross-border seller.
Sales & price currency: sales / monthlySalesUnits are 30-day units; price is in Russian rubles (₽), indicated by currency.
Parameters
| Parameter | Type | Required | Description |
|---|---|---|---|
| id | integer | yes | Shop (seller) ID — the sellerId from other Seerfar Ozon tools. Negative = Ozon platform seller. |
| page | object | yes | Pagination {page, pageSize, orders[]}. |
| page.page | integer | no | Page number, from 1 (default 1). |
| page.pageSize | integer | no | Page size, default 20. Max 20 — larger values are rejected (errcode 1002). |
| page.orders | array | no | Sort rules, elements {field, direction}; direction DESC/ASC. Common fields: sales, price, reviewRating, upTime. |
| uId | string | no | User ID. |
| memberId | string | no | Member ID (data attribution). |

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.
