The agent successfully assembled a comprehensive understanding of TIER IV by combining official site content (homepage, about, products pages) with web search results and prior knowledge. The site itself provided clear positioning and product names, but lacked pricing details, detailed product differentiation, and feature comparisons—forcing the agent to rely heavily on press releases and external sources to construct a complete answer.

• ›Steps [1], [4], [8], [10] returned core identity content: mission statements ('democratization of autonomous driving'), three product names (Pilot.Auto, Web.Auto, Edge.Auto), and Autoware's open-source foundation. This was the backbone of the 'what they do' and 'who it's for' sections.
• ›Steps [17] and [24] confirmed Autoware's open-source status and global community focus, but contained no technical differentiation or use-case details beyond meta descriptions.
• ›The site's product pages ([8], [10]) list the three platforms by name and general function, but do not provide comparison tables, feature matrices, or clear guidance on which product to use for which scenario—the agent had to infer this from press releases ([25] search results were cited but not fetched directly).
• ›Pricing was entirely absent from the site—steps [6] /pricing returned 404. The agent filled this gap using external sources (search [22], [23]) indicating a 'free software + paid services' model, but no specific pricing tiers, subscription costs, or licensing terms are published on tier4.jp.
• ›The site has two domains (tier4.jp and tier4.co.jp) with inconsistent structure; /products exists on tier4.jp but /products/pilot-auto, /products/web-auto, /products/edge-auto all returned 404, suggesting single overview page rather than individual product pages—agent-unfriendly for deep dives.
• ›Agent relied on prior knowledge (19%) and web search (19%) more than direct site content (63% from previous artifact, likely cached/reused), indicating the site does not self-contain the full narrative needed to answer the task without external bridging.
