CLAIMS ON THE CARD, AS CHECKED

01 Answers a plain-text property question with matches: count, references, prices and page URLs (AMLI 3-bedroom Lisbon example) Probe '3-bedroom apartment for sale in Lisbon with garage': answered '3 properties found' with references (META-001009...), prices (e.g. 1.030.000 EUR for a 200 m2 T3 duplex), sizes and page URLs; structured data part carries total and the property list. VERIFIED live probe of the pesquisar_imoveis skill
02 The listing pages it returns exist on its own site 3 of 3 returned URLs returned HTTP 200 on metastate.pt and the URL slugs match the returned property titles; page titles load client-side, so title text was not asserted. VERIFIED HTTP spot-check of returned listing URLs
03 Official market-price data skill answers with a sourced figure Probe 'Price per m2 in Cascais': answered Cascais municipality median 5.000 EUR/m2, 1st quarter 2026, naming the source (INE, Estatisticas de Precos da Habitacao ao nivel local) and the report edition. Figure not independently re-checked. VERIFIED live probe of the consultar_precos_mercado skill
04 Purchase-cost skill answers as the card describes, and contact-creating skills behave The card's own plain-text example ('How much tax do I pay buying a 750,000 euro flat?') returned an input prompt for preco_eur instead of parsing the price; structured data-part probes returned no readable answer. Viewing/valuation/consultant-contact skills create real requests at the agency and were deliberately not exercised. NOT VERIFIED live probes of the calcular_custos_compra skill
