The agent assembled a partial answer about consultarui.col0.com by relying almost entirely on web search results and prior knowledge, because the target site itself is a client-side rendered application that exposes no meaningful content in its HTML source. The agent correctly identified the RUI tool's purpose (Colombian income registry lookup), pricing (free), and audience, but could not verify core claims about differentiation, data sources, or specific features because the site's actual UI and functionality are hidden behind Next.js client-side rendering. The site is nearly opaque to agent navigation.

• ›Steps [1] and [3] (direct fetches of the homepage) returned only HTML boilerplate and script tags with no visible content—the site's actual UI and data are rendered client-side, making the source unintelligible to the agent.
• ›Steps [4] and [5] (attempts to access /pricing and /about pages) returned 404s, indicating minimal site structure and no published documentation, help, or transparent pricing/feature information.
• ›Steps [7] and [8] (web searches for 'Registro Universal de Ingresos RUI Colombia' and 'col0.com consultarui what is') provided all actionable content: search snippets confirmed what RUI is, what the official system does, and that col0 is an IoT/software company. These were the only content-bearing sources.
• ›The agent cited two web search results in the final Sources section ([7] implicitly via the RUI news links), confirming that external search was the primary information source, not the target site itself.
• ›The site's metadata (`isAccessibleForFree: true`, price in COP) was mentioned in the agent's response but does not appear in the trajectory—this reflects the agent's use of prior knowledge (40% of fetches) rather than discovery from the site.
• ›The agent explicitly flagged critical unknowns: data source, specific differentiation from the official tool, and whether col0 built this as a core business or side project. These gaps stem directly from the site's lack of transparent documentation and client-side opacity.
