Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (8)

find_cheaperGiven a product (by Lowvyn ID or retailer URL), return the same physical product on other Canadian retailers with their current prices and savings. Uses verified UPC matches. Use this when a user wants to know 'can I get this cheaper somewhere else?'.
get_categoriesList the product categories Lowvyn covers, with item counts. Useful for narrowing search_products calls.
get_price_historyReturn the daily price history for a product as (date, price) pairs, up to N days. Use this to verify whether a 'sale' is genuine or whether the price has been higher in the past, or to show a price trend in an answer to the user.
get_productLook up a product by Lowvyn ID OR retailer URL (amazon.ca / walmart.ca / bestbuy.ca / canadiantire.ca). Returns title, current price (CAD), Lowvyn Score (0-100), Deal Verdict, and price summary (current / all-time low / all-time high).
get_retailersList the Canadian retailers Lowvyn currently tracks, with item counts and last-update timestamps.
intent_searchSearch the Canadian catalogue by a natural-language description of a NEED rather than keywords. Give it what the shopper actually wants (e.g. 'a quiet gaming laptop under $1500', 'a reliable stroller for travel') and it returns the best-matching products with their current price (CAD), Lowvyn Score, and Deal Verdict, plus what it understood (category, budget, must-haves). A relevance model does the matching; the deterministic deal gate decides the verdict — it never inflates a deal. Use this when the user describes a use case, budget, or constraints instead of naming a product; use search_products for a plain category/price filter. Each result carries an id + canonicalUrl you can pass to get_product, verify_deal, or find_cheaper.
search_productsSearch the Canadian product catalogue. Filter by category slug, max price (CAD), and retailer. Returns up to 20 matching products with current price and Lowvyn Score. Use this when a user is exploring what is available in a category rather than asking about a specific product. Each result carries an id + canonicalUrl you can pass to get_product, verify_deal, find_cheaper, or get_price_history.
verify_dealGiven a product (by Lowvyn ID, retailer URL, or a lowvyn.com product URL from another tool's result) and an optional claimed price, return whether the deal is genuine. Compares against Lowvyn's price history and returns a verdict ('real_deal', 'modest_deal', 'average', 'bad_time', 'insufficient_data') plus an explanation. Use this first when a user asks 'is this actually a good price?'. Accepts the id or canonicalUrl from a search_products / intent_search result directly.
