What it does
Clear alt text on every product image, so AI tools know what each one shows. Shopping agents cannot see pixels. They read the alt text to judge color, material and style, and a file name like IMG_2931 tells them nothing. Claude finds product images with blank or low-value alt text. For each, it writes a short, specific line covering what the product is, its color and material, and how it is shown. You review the lines before anything is saved. The change updates live files, so you need an authenticated Shopify CLI session with product and file write access.
