Purpose

用途

Scans all product variants and identifies duplicate SKUs or barcodes — two or more variants sharing the same identifier. Duplicate SKUs cause inventory sync failures, incorrect order routing, and accounting mismatches. Read-only — no mutations.

扫描所有商品变体，识别重复的SKU或条形码——即两个或多个变体共用同一个标识符。重复的SKU会导致库存同步失败、订单路由错误以及账目不匹配。本工具为只读模式，不会执行任何变更操作。

Workflow Steps

工作流步骤

OPERATION:
```
productVariants
```
— query Inputs:
```
first: 250
```
, select
```
sku
```
,
```
barcode
```
,
```
product { title }
```
, pagination cursor Expected output: All variants with SKU and barcode values; paginate until
```
hasNextPage: false
```

Build in-memory map of

sku → [variants]

and

barcode → [variants]

Report all keys with more than one variant (duplicates)
If
```
include_blank
```
: additionally flag variants where
```
sku
```
is null or empty string

操作：
```
productVariants
```
— 查询 输入：
```
first: 250
```
，选择
```
sku
```
、
```
barcode
```
、
```
product { title }
```
、分页游标 预期输出： 所有带SKU和条形码值的变体；分页直到
```
hasNextPage: false
```

在内存中构建

sku → [variants]

和

barcode → [variants]

的映射表

上报所有对应变体数量大于1的键（即重复项）
如果开启
```
include_blank
```
：额外标记
```
sku
```
为null或空字符串的变体

Session Tracking

会话跟踪

Claude MUST emit the following output at each stage. This is mandatory.

On start, emit:

╔══════════════════════════════════════════════╗
║  SKILL: Duplicate SKU/Barcode Detector       ║
║  Store: <store domain>                       ║
║  Started: <YYYY-MM-DD HH:MM UTC>             ║
╚══════════════════════════════════════════════╝

After each step, emit:

[N/TOTAL] <QUERY|MUTATION>  <OperationName>
          → Params: <brief summary of key inputs>
          → Result: <count or outcome>

On completion, emit:

For

format: human

(default):

══════════════════════════════════════════════
DUPLICATE SKU / BARCODE REPORT
  Variants scanned:      <n>
  Duplicate SKUs found:  <n> groups
  Duplicate barcodes:    <n> groups
  Blank SKUs:            <n>

  Duplicate SKU groups:
    SKU "ABC-123"  — used by 2 variants:
      Product A / Blue / L
      Product B / Navy / XL
  Output: duplicates_<date>.csv
══════════════════════════════════════════════

For

format: json

, emit:

json

{
  "skill": "duplicate-sku-barcode-detector",
  "store": "<domain>",
  "variants_scanned": 0,
  "duplicate_sku_groups": 0,
  "duplicate_barcode_groups": 0,
  "blank_skus": 0,
  "output_file": "duplicates_<date>.csv"
}

Claude必须在每个阶段输出以下内容，这是强制要求。

启动时，输出：

╔══════════════════════════════════════════════╗
║  SKILL: Duplicate SKU/Barcode Detector       ║
║  Store: <store domain>                       ║
║  Started: <YYYY-MM-DD HH:MM UTC>             ║
╚══════════════════════════════════════════════╝

每步完成后，输出：

[N/TOTAL] <QUERY|MUTATION>  <OperationName>
          → Params: <brief summary of key inputs>
          → Result: <count or outcome>

运行完成时，输出：

当

format: human

（默认）时：

══════════════════════════════════════════════
DUPLICATE SKU / BARCODE REPORT
  Variants scanned:      <n>
  Duplicate SKUs found:  <n> groups
  Duplicate barcodes:    <n> groups
  Blank SKUs:            <n>

  Duplicate SKU groups:
    SKU "ABC-123"  — used by 2 variants:
      Product A / Blue / L
      Product B / Navy / XL
  Output: duplicates_<date>.csv
══════════════════════════════════════════════

Error Handling

错误处理

Error	Cause	Recovery
`THROTTLED`	API rate limit exceeded	Wait 2 seconds, retry up to 3 times
No duplicates found	Clean catalog	Exit with ✅ no issues found

错误	原因	解决方案
`THROTTLED`	API速率限制超出	等待2秒，最多重试3次
未找到重复项	目录数据干净	返回✅未发现问题后退出

Best Practices

最佳实践

Run this skill after every bulk product import — imports are the most common source of duplicate SKUs.
A shared SKU across products is only valid if you intentionally use the same SKU for reprints or variants — most cases are data errors.
Blank SKUs are not duplicates but can cause problems with 3PLs and fulfillment systems that require a SKU for every variant — use
```
include_blank: true
```
to surface them.
After identifying duplicates, use the Shopify Admin UI or the
```
productVariantsBulkUpdate
```
mutation to correct SKU values.

每次批量导入商品后运行本skill——导入操作是重复SKU最常见的来源。
只有当你有意为再版商品或变体使用相同SKU时，跨商品共享SKU才是合理的，绝大多数此类情况都是数据错误。
空SKU不属于重复项，但会给要求每个变体都有SKU的第三方物流和履约系统带来问题——可使用
```
include_blank: true
```
来找出这类SKU。
识别到重复项后，可使用Shopify管理后台UI或
```
productVariantsBulkUpdate
```
mutation修正SKU值。
