"description": "Find fashion products using natural language and/or structured filters. Provide a `query` for semantic ranking via multimodal text+image embeddings (\"oversized wool coat\", \"black leather jacket\", \"minimalist gold jewelry\", \"linen shirt for a beach wedding under $200\") — best for open-ended discovery. Keep queries concrete: noun-led with up to one or two modifiers works best (\"summer linen shirt\" beats \"breathable linen shirt perfect for summer\"). Provide only structured filters (category, brand, colors, gender, price, etc.) for pure browse — results are recency-ranked and paginate cleanly. Combine both for filtered semantic search. At least one of query or a filter must be provided.\n\nExample calls (notice the sparse filter population — descriptive attributes stay in `query`, not in structured fields):\n- \"linen wedding guest dress under $200\" → {query: \"linen wedding guest dress\", gender: \"women\", max_price: 200, materials: [\"linen\"]}\n- \"wool coat under $300\" → {query: \"wool coat\", gender: \"women\", max_price: 300, materials: [\"wool\"]}\n- \"browse women's black dresses $100-$300\" → {gender: \"women\", category: \"clothing/dresses\", colors: [\"black\"], min_price: 100, max_price: 300}\n- \"Acne Studios outerwear\" → {query: \"outerwear\", brand: \"Acne Studios\", gender: \"women\"}\n\nReturns compact product cards: AI-generated summary, price, images, tags, and compact availability by color/size; variant price differences are nested under the availability dimension that determines price. For merchant description, store info, SKU-level variants, exact variant prices, and all product images, call get_product with a product ID from these results. Multi-currency prices supported (e.g. \"under 200 zł\" or min_price=200 + currency=\"PLN\"); returned prices render in the requested currency when provided.",
