Changes things 1Claude Code: ask
  • price_productExact live price in USD for a fully configured item — the same number the customer pays on 25karats.com (computed from current metal market pricing, not a cached feed price).No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Exact live price in USD for a fully configured item — the same number the customer pays on 25karats.com (computed from current metal market pricing, not a cached feed price). Identify the item by variant_id (from get_product) or style_code, optionally with metal. For wedding bands pass ring_size/width/thickness/color/finish (option_value ids or display values from get_product); for his & hers sets pass his/her objects with those keys; for engagement rings pass stone_type and ring_size. Unset axes use the product's defaults. Returns the price, the resolved configuration, and a deep_link_url that opens the product page pre-configured for checkout. Invalid values return the list of valid ones — correct and retry. Any option group can also be set through the options object keyed by the option_id values returned by get_product (the only way to configure generic jewelry). His & hers options and engraving belong inside the respective his/her object. Inputs that do not apply to the item (stone_type on a band, top-level ring_size on a set) are rejected with the inputs that do; settings sold without a center stone say so in configuration and notes.

  • browse_collectionBrowse one collection/category page deterministically — the same product set, ordering, and filters a shopper sees on the site.No findings

    Why it is in this group

    • The name "browse_collection" says "browse": a word for reading.
    Description, as the server wrote it
    Browse one collection/category page deterministically — the same product set, ordering, and filters a shopper sees on the site. Pass the collection permalink from list_collections (e.g. 'wedding-rings/womens/eternity'). Filter by style tags, metals, or sort; paginate 24 per page. Prefer search_products for free-text intent and this tool for "show me everything in X".

    Why it is in this group

    • The name "get_product" says "get": a word for reading.
    Description, as the server wrote it
    Full detail for one product: metal variants with live starting prices, the complete customization matrix (ring sizes, widths, thickness, color, finish, stone type, engraving rules) with the ids to echo into price_product, stone specifications, physical dimensions, size-group siblings, matching pieces, and the default image. Identify the product by exactly one of slug, style_code, or url (any 25karats product URL works).

    Why it is in this group

    • The name "get_product_images" says "get": a word for reading.
    Description, as the server wrote it
    Every gallery image for a product with high-resolution URLs. Each image lists only renditions that actually exist, largest first — modern photography is 2048x2048 WebP at the 'original' size — plus the metal tone, band width, and finish the photo shows, and descriptive alt text. Identify the product by exactly one of slug, style_code, or url.

    Description, as the server wrote it
    Search 25karats' in-stock IGI/GIA-certified lab-grown loose diamonds (center stones for engagement rings) by shape, carat, color, clarity, cut, and price.

    Why it is in this group

    • The name "search_products" says "search": a word for reading.
    Description, as the server wrote it
    Search the 25karats made-to-order catalog (wedding bands, engagement rings, his & hers sets, fine jewelry) by keywords or a style code. Use this first when a shopper describes what they want ("braided mens wedding band", "vintage engagement ring"). Returns product cards with live starting prices in USD, image URLs, and product URLs. Follow up with get_product for options and price_product for an exact configured price. total_count is exact unless capped is true; capped counts are lower bounds imposed by the search index.
