The agent assembled a comprehensive explanation of Starlite Festival by combining minimal content from the official website (homepage and programming page) with external sources found via web search. The official site proved navigation-ready but content-sparse on key details (pricing, positioning, differentiation), forcing the agent to rely heavily on third-party sources (spain.info, Andalucia.com, Wikipedia, real estate blogs) to answer the task. The agent successfully delivered a complete, well-structured answer by synthesizing fragments across sources.

• ›Steps [1] and [3] (homepage fetches in Spanish and English) returned HTML but no rendered text showing what Starlite is, who it targets, or pricing—these were JavaScript-heavy landing pages that did not expose content-bearing data in the fetch response.
• ›Step [5] (programacion/programming page) similarly returned shell HTML without visible concert data, pricing, or lineup information embedded in the response.
• ›Steps [7], [9], and [11] (web searches) were the actual content sources—search snippets and linked third-party pages (spain.info, Andalucia.com, panoramamarbella.com, Wikipedia) provided the quarry venue differentiator, pricing ranges (€39–€59), capacity, curated positioning, and festival dates. These external sources did the explanatory work the official website did not.
• ›The agent explicitly cited five external sources in its final response and did not cite the official starlitefestival.com pages—a signal that the official site did not contain the information needed to fulfill the task.
• ›The site's JavaScript-heavy architecture (Next.js with dynamic content loading) made static fetches uninformative; the agent correctly inferred this limitation and pivoted to search to gather the required context.
• ›Agent-readiness is low on the official site: no structured data (schema.org), no plain-text positioning statement, no pricing table, no comparison against competitors. Explainability required external triangulation.
