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 →
- high System Prompt Leakage · line 101 Skill contains instructions that could directly expose system prompts, internal rules, or hidden instructions to users or external parties.Fix: Remove any instructions that reveal, print, or output system prompts or internal rules. 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 | $0.00221 | $0.03352 |
| Opus 5 | $0.00111 | $0.01676 |
| Sonnet 5 | $0.00044 | $0.00670 |
| Haiku 4.5 | $0.00022 | $0.00335 |
Grade A, and why
linkfox-seerfar-ozon-category-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 Category Search
This skill lists the products of a specific Ozon category from the Seerfar analytics database. Given a categoryId, it returns category-level aggregates (total sales, total revenue, average price, average rating, seasonality) plus each product's sales, price, rating, review count, brand and seller — the starting point for category selection analysis, best-seller mining within a category, and category capacity / price-band analysis.
Core Concepts
Unit of data is the product, scoped to one category: pass a single categoryId and receive that category's product list with performance metrics, alongside category-level aggregates. This is a category-level view, not a shop or keyword view.
Where the categoryId comes from: categoryId is the Ozon category identifier — a hierarchical path joined by _ (e.g. 15621032_15621049_115951147), obtained from the Ozon category document or from other Seerfar Ozon tools. If the user only has a category name, first resolve it to a categoryId from an upstream Seerfar Ozon source before calling this skill.
Category aggregates vs product rows: the response carries both category-level totals (totalSales, totalRevenue, avgPrice, rating, seasonalityAmplitude, seasonalityCoef, startDate/endDate) and a paginated product list (data / products). Use the aggregates for category sizing and the rows for individual product analysis.
Sales & price currency: sales / monthlySalesUnits are units; price / revenue are in Russian rubles (₽), indicated by currency.
Time window: by default the data covers the last 30 days (startDate / endDate show the actual range). Pass date as yyyy-MM (e.g. 2026-02) to query a historical month snapshot.
Parameters
| Parameter | Type | Required | Description |
|---|---|---|---|
| categoryId | string | yes | Ozon category ID, e.g. 15621032_15621049_115951147 (levels joined by _). |
| 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} (both required); direction DESC/ASC. Common fields: sales, price, revenue, reviewRating. |
| date | string | no | Historical month yyyy-MM (e.g. 2026-02); omit for last 30 days. |
| fulfillment | string | no | Fulfillment filter, one of FBO / FBS / RFBS / FBP / OZON; omit to query all. Single string, not an array. |
| uId | string | no | User ID. |
| memberId | string | no | Member ID (data attribution). |
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
