Metafield Bulk Update

### name Metafield Bulk Update — Structured Data Across an Entire Collection ### oneLiner Sets or deletes metafield values on hundreds of products at once — no manual product-by-product editing required. ### whenToUse - Before launching a new storefront feature that requires a metafield to be filled across an entire product category. - After a product import, when fields like material composition or care instructions were left blank. - When restructuring store data and needing to rewrite old metafield values to a new namespace or key. ### howToRun ``` Run skill: shopify-admin-metafield-bulk-update Store: yourstore.myshopify.com filter: tag:summer-collection namespace: custom key: material value: "100% Cotton" value_type: single_line_text_field action: set dry_run: true ``` ### whatYouGet A CSV file `metafield_update_YYYY-MM-DD.csv` with columns: `resource_type`, `resource_id`, `title`, `namespace`, `key`, `old_value`, `new_value`, `action`. The skill batches up to 25 metafields per API request and handles large catalogs automatically. Verify that `namespace` and `key` match your store's metafield definitions before running without `dry_run`. ### polishContext ### safetyNote This skill executes `metafieldsSet` or `metafieldsDelete` mutations — `metafieldsSet` overwrites existing values without merging, and `metafieldsDelete` removes them permanently. Default is `dry_run: true`. Preview before committing to large product sets.
