The agent successfully assembled a comprehensive overview of Mahou San Miguel by working around an age gate that blocked direct access to the website's full content. It retrieved corporate information (About Us page) and brand portfolio details from the site itself, then filled gaps using web search to understand pricing, B2B/B2C channels, and competitive positioning. The site is poorly agent-navigable due to the age verification gate, forcing reliance on external sources and prior knowledge for most actionable details.

• ›Steps [5] (About Us) and [7] (Brands page) were the only direct site fetches that returned meaningful content; both yielded truncated HTML with metadata but full page body was blocked by the age gate, limiting what the agent could extract about products, pricing, and positioning.
• ›The agent had to use web search (steps [4], [6], [8], [10], [11]) to source 50% of its answer, accessing Wikipedia, case studies, and news articles about Mahou San Miguel's business model, e-commerce platform (Solana), B2B offerings (Rentabilibar), and pricing structure—none of which were directly readable from the corporate website.
• ›The site's age gate severely degraded agent-readiness: the agent explicitly noted it could only see 'header/footer elements' and could not access pricing, product detail pages, or marketing campaigns. The website is designed as a corporate/institutional presence rather than a machine-readable information source, with consumer transactions deliberately routed to a separate Solana e-commerce domain.
• ›Prior knowledge (25% of sources) and previous artifacts (25%) supplemented the web search, indicating the agent filled significant gaps by reasoning from general knowledge about beer industry structures rather than discovering them from the site.
