What it does
Change prices across a whole collection or tag in one go, within a floor and a ceiling you set. It edits live prices, so preview first. You name a collection or product tag, then say whether to adjust by percent or by a fixed amount. A negative value means a discount. Minimum and maximum prices keep any variant from going too low or too high. The skill can run in preview mode that lists every change without applying it. Use it for storewide sales, ending a promotion, passing on a supplier increase or aligning prices. It works through Shopify, so you need the CLI signed in with permission to read and write products.
