The agent successfully assembled a comprehensive explanation of laureberti.github.io by combining content from the researcher's main website, Learn2Clean documentation, and the IDEAL Lab's official IRD page. The site itself was poorly navigable — the root domain returns a 404, forcing the agent to rely on web search to discover the correct `/website/` subdirectory — but once located, the pages contained enough biographical, project, and research information to answer all aspects of the task (what they do, who it's for, pricing, differentiation).

• ›Steps [5] and [6] returned the main portfolio page with meta description indicating research focus on 'data quality, machine learning, truth discovery, anomaly detection, multimodal AI, and AI for sustainable development,' plus author/affiliation metadata — the foundation for answering 'what they do' and 'who it's for'.
• ›Step [10] (Learn2Clean documentation) provided technical details about the reinforcement learning approach that differentiated the tool from competitors, directly supporting the 'how it's different' section of the answer.
• ›Step [14] (IDEAL Lab IRD page) confirmed institutional context and research scope (60+ researchers, Franco-Brazilian collaboration, sustainability focus), adding authority to claims about the lab's scale and mission.
• ›The site's root URL (laureberti.github.io) is entirely inaccessible via direct navigation — this is a critical discoverability failure that forced the agent into web search [3] to find the correct path. The agent had to work around broken routing rather than being guided by the site itself.
• ›No pricing, support, or commercialization information was present on any fetched page, but the agent correctly inferred 'free/open-source' from the GitHub/academic context and absence of payment language — this inference was sound but not explicitly stated anywhere on the site.
• ›The agent cited all four content-bearing fetches in its final Sources section, indicating they were necessary to construct the answer. No single page contained all required information; the answer required assembly from fragmented sources across multiple domains.
