}Always call this tool when the shopper asks to show, open, view, review, or check their cart. It renders the interactive cart UI; do not replace it with a text-only cart summary.
No arguments.
{
"type": "object",
"title": "render_cartArguments",
"properties": {}
}Use this when a shopper wants Lorenzo products to pair, match, style or wear with a specific product. Render Complete the Look with store-configured complementary products and supplementary items. Examples: 'what can I pair with this?', 'what can I match?', 'suggest a suitable pair', 'suitable matching suggestions', 'recommend matching products', 'what goes well with it?', 'dress to pair with this product', or 'complete this outfit'. Follow-up pairing requests also need this tool when the subject is clear from current-store context; the shopper does not need to say 'Complete the Look' or 'call the tool'. Do not substitute a text-only styling answer for fetching store recommendations. For one subject product, call this tool exactly once. For multiple explicitly named subject products, call it at most once per subject. Do not call it automatically after an ordinary discovery search, and do not additionally open product search or product detail merely to prepare, validate, rank, compare, or explain these recommendations. Pass a known current-store product ID, otherwise the subject's exact title in query; this tool resolves it internally. Do not call product search first merely to resolve the subject. If 'this/it' is ambiguous or no subject is identified, ask which product rather than guessing. General shopping suggestions without a subject belong to render_product_search. If no matching products are configured, explain the returned limitation without inventing pairs or opening another UI.
| Argument | Type | Description |
|---|---|---|
| query | any | Subject product's exact current-store title, extracted from user wording or prior store context, when product_id is unknown. Example: 'Painter Tee - Black'. Do not pass the whole pairing question, 'this product', or the desired matching category. |
| product_id | any | Exact Shopify product GID of the subject to match, from a previous current-store result. Prefer this over query; never invent an ID or use a different store's ID. |
Render the interactive detail UI for one exact Lorenzo product. Pass a product_id when known; otherwise pass the exact product-name query directly because this tool resolves it internally. Use this only when the shopper explicitly asks to view, inspect, review, or get specifications for one exact product, or selects a product from search results. Do not call it automatically to rank, compare, validate, or explain discovery results. Do not call product search first to resolve the product. For matching items, recommended pairs or what to wear with this product, use render_complete_the_look instead.

}Search Lorenzo and render the interactive product carousel. Pass the shopper's product wording through in query without rewriting it. When the shopper states a budget, provide min_price and/or max_price in major currency units; use both with the same value only for an exact price. For one requested category or concept, call this tool exactly once and do not repeat or rephrase the search. If no products are returned, show the empty result and ask before trying a different query or relaxing constraints. For multiple explicitly requested categories, use one faithful combined search when possible; otherwise call this tool once per distinct category. Do not create separate searches for synonyms, colours, styles, audiences, or alternative wording. Use this for browsing or discovery, not as a preliminary lookup for an exact product-detail request. Do not automatically open product-detail tools for returned products to rank, compare, validate, or explain the results. For products to pair or match with a referenced item, use render_complete_the_look instead.
| Argument | Type | Description |
|---|---|---|
| limit | integer | Maximum products to return. |
| query* | string | The shopper's product wording, passed to Shopify unchanged. |
| currency | any | ISO 4217 currency code. |
| max_price | any | Optional maximum price in major currency units. |
| min_price | any | Optional minimum price in major currency units. |
| buyer_context | any |

}We read every tool's name, description and inputs the way the model will, looking for instructions hidden from you. A clean result means no warning signs, not a guarantee. Scanned Nov 5, 2026.
No readOnlyHint / destructiveHint annotations, so clients can't tell a read from a write without asking.
Fix: Add annotations to each tool, e.g. { readOnlyHint: true } for tools that only read.
