# MPSTATS Ozon Seller Products

This skill drills into all Ozon (Russia) products sold by a given seller, returning per-SKU sales, revenue, price, rating, stock, turnover, lost profit, and more. Designed for store-structure audits, bestseller dissection within a shop, and head-to-head competitor-store comparison.

## Core Concepts

**Seller ID, not name**: `sellerId` must be a **numeric string** — the `sellerId` field Ozon / MPSTATS uses to identify a shop. Do **not** pass a brand name, category path, or human-readable seller name. If you only have the seller name, resolve the ID via `mpstats-ozon-product-search` (seller-filtered) and read `sellerId` from the result.

**Filters & ops**: Same AND-combined numeric filter model as `brand-products` and `category-products`. See Filter Reference.

**Currency**: Default `RUB`; override with `currency` / `currencyRate` for USD / EUR / CNY views.

**FBO / FBS**: `includeFbs: true` folds FBS into the numbers; `false` keeps FBO-only.

## Parameters

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| sellerId | string | yes | Ozon seller ID as numeric string, e.g. `"3628678"` |
| startDate | string | no | Stats window start, `YYYY-MM-DD`; latest = yesterday |
| endDate | string | no | Stats window end, `YYYY-MM-DD`; latest = yesterday |
| page | integer | no | Page number, starts at 1 |
| pageSize | integer | no | Rows per page, 1-100, default 100 |
| sortField | string | no | snake_case column (`sales`, `revenue`, ...) |
| sortDirection | string | no | `asc` / `desc` |
| currency | string | no | Currency code, default `RUB` |
| currencyRate | integer | no | Custom rate for non-default currency |
| includeFbs | boolean | no | Include FBS data |
| filters | array | no | Numeric filter list |

## Filter Reference

Each `filters` entry: `{"field": "<snake_case>", "op": "<OP>", "value": <num>, "value2": <num?>}`.

**Common fields**: `sales`, `final_price`, `rating`, `comments`, `balance`, `revenue`, `days_in_stock`, `turnover_days`, `lost_profit`, `category_position`.

**Operators**: `GTE`, `LTE`, `GT`, `LT`, `EQ`, `NOT_EQ`, `BETWEEN` (requires `value2`).

## 调用方式

- **API 端点**：`POST /mpstats/ozon/sellerProducts`（完整参数/响应/错误码见 `references/api.md`）
- **Python 脚本**：`python scripts/mpstats_ozon_seller_products.py '<JSON 参数>' [--inline]`
- **成本约束**：本工具会消耗算力；同一会话同一参数组合默认只调用一次，脚本带 24h 本地缓存。失败/空结果不得自动换关键词、翻页或改邮编连续试探；需要继续检索时先向用户说明会产生额外消耗。

**输出策略（脚本默认行为）**：
- **始终**将完整响应写入 `<cwd>/linkfox/<YYYY-MM-DD>/<session>/data/linkfox-mpstats-ozon-seller-products-<timestamp>.json`（`<cwd>` 为脚本执行时的工作目录，在 Claude Code 里即当前项目目录；`<session>` 取自环境变量 `SESSION_ID`，按用户任务自动聚合；**禁止写入 /tmp**，当前目录不可写则报错）
- 响应体 ≤ 8 KB：落盘后把完整 JSON 打印到 stdout
- 响应体 > 8 KB：落盘后 stdout 只输出摘要（顶层字段、常见计数如 `total`/`costToken`、最大列表字段的长度 + 前 3 条样本）
- 加 `--inline` 强制全量打印到 stdout（同样落盘）

**读数据建议**：先看摘要判断是否足够；需要具体字段时优先用 `jq`或`ConvertFrom-Json` 从保存的 json 文件按需抽取，避免整份 JSON 进入上下文。
## 解决认证和算力问题
发生以下异常情况时，采用 references/onboarding.md 引导解决问题：

### 异常情况
- **未配置API Key**：环境变量未配置 `LINKFOX_AGENT_API_KEY`，也未配置 `LINKFOXAGENT_API_KEY`。
- **响应401或402状态码**
- **响应提示算力或余额不足**：消息含"算力余额不足/计费不足/余额不足/quota exceeded/insufficient balance/套餐到期/需充值/请充值"，或类似含义的内容。

## Usage Examples

**1. Seller's top-100 by sales**
```json
{
  "sellerId": "3628678",
  "sortField": "sales",
  "sortDirection": "desc",
  "pageSize": 100
}
```

**2. Store's revenue top-20**
```json
{
  "sellerId": "3628678",
  "sortField": "revenue",
  "sortDirection": "desc",
  "pageSize": 20
}
```

**3. High-turnover star products**
```json
{
  "sellerId": "3628678",
  "filters": [
    {"field": "sales", "op": "GTE", "value": 30},
    {"field": "turnover_days", "op": "LTE", "value": 20}
  ],
  "sortField": "revenue",
  "sortDirection": "desc"
}
```

**4. Stockout pain points for the store**
```json
{
  "sellerId": "3628678",
  "filters": [{"field": "lost_profit", "op": "GTE", "value": 100000}],
  "sortField": "lost_profit",
  "sortDirection": "desc"
}
```

**5. USD-converted store audit**
```json
{
  "sellerId": "3628678",
  "currency": "USD",
  "sortField": "revenue",
  "sortDirection": "desc"
}
```

## Display Rules

1. **Compact store table** — key columns: `productId`, `title`, `brand`, `price`, `monthlySalesUnits`, `monthlySalesRevenue`, `rating`, `balance`, `turnoverDays`, `lostProfit`, `position`.
2. **Revenue share = within this seller query** — 0-100%; clarify the base.
3. **Russian titles** — preserve; translate on user request.
4. **Currency labeling** — if converted, note `"已按 USD 换算"`.
5. **Pagination** — for stores with thousands of SKUs, suggest tighter filters before paging deep.
6. **No buying advice** — the skill shows the store's book, not whether their SKUs are worth copying.

## Important Limitations

- **Numeric seller ID only** — passing a seller **name** will not resolve; go through `mpstats-ozon-product-search` first.
- **Page cap** — max 100 rows per page.
- **T-1 data** — `endDate` cannot be today or a future date.
- **No business advice** — data-only.
- **Ozon-only** — Wildberries / other Russian marketplaces are separate.

## User Expression & Scenario Quick Reference

**Applicable** — Seller-scoped Ozon product metrics:

| User Says | Scenario |
|-----------|----------|
| "Show me everything seller 3628678 sells, by sales" | Store SKU map |
| "What are this Ozon store's top revenue products" | Store bestseller drill |
| "How many SKUs does the store have with turnover <20 days" | Operational health filter |
| "Where is this store losing money to stockouts" | Lost-profit scan |
| "Compare two Ozon stores' SKU counts and sales" | Store-vs-store benchmarking (call twice) |

**Not applicable** — Needs beyond seller drill-down:

- Only seller **name** known → use `mpstats-ozon-product-search` to resolve the ID
- Brand-scoped drill → `mpstats-ozon-brand-products`
- Category-scoped drill → `mpstats-ozon-category-products`
- Single-SKU time-series → `mpstats-ozon-product-trend`
- Wildberries / other Russian marketplaces → not covered

**Boundary judgment**: Use this skill when the **dimension is a specific seller** and you want the per-SKU table under that shop. For "who are the top sellers in category X" you'd use category drill-down and group by seller client-side.

## 算力消耗规则

按动态规则计费：消耗算力 = 12。列表为空返回 0
