The agent extracted what Mein Kegelbuch does and who it serves from the homepage, but could not locate pricing information despite multiple attempts—neither the site nor web search yielded cost details, leaving the answer incomplete on a critical commercial dimension.

• ›Step [1] returned rich feature descriptions directly from the homepage, making the product's purpose immediately clear and requiring no assembly from fragments.
• ›Steps [2] and [5] revealed the site lacks standard navigation paths (/preise, /faq returned 404), forcing the agent to guess URLs rather than follow links.
• ›Step [6] web search yielded unrelated results (Amazon physical books, other apps) and failed to surface pricing, indicating poor external indexing or the absence of public pricing documentation altogether.
• ›Step [4] relied on re-fetching the homepage to extract positioning and differentiation language already visible in step [1], suggesting the agent was working from model synthesis rather than discovering new content.
• ›The final response explicitly cites only one source (mein-kegelbuch.de directly), despite retrieving and synthesizing information across multiple steps, indicating the site was the sole reliable primary source but was incomplete for the task.
