Duplicate SKU/Barcode Detector

### name Duplicate SKU and Barcode Detector ### oneLiner Scans all variants and reports every SKU or barcode assigned to more than one variant in the catalog. ### whenToUse - After every bulk product import — imports are the most common source of duplicate SKUs. - When a 3PL or WMS reports order routing errors for specific SKUs. - Before integrating a new fulfillment system that requires unique identifiers on every variant. ### howToRun ``` Run skill: shopify-admin-duplicate-sku-barcode-detector Store: yourstore.myshopify.com check_skus: true check_barcodes: true include_blank: true ``` ### whatYouGet A CSV file `duplicates_YYYY-MM-DD.csv` with columns: `issue_type`, `duplicate_value`, `variant_id`, `product_title`, `variant_title`, `sku`, `barcode`. Duplicate SKUs are grouped — for each group you see exactly which variants and products share the same identifier. Use `include_blank: true` to also surface variants with no SKU set, which cause fulfillment problems regardless of duplication. ### polishContext ### safetyNote
