The agent successfully assembled a comprehensive explanation of d.design by combining information from third-party tool directories and a Baidu wiki entry, since the official site itself (fetches [1] and [6]) returned only truncated HTML and required login to access pricing ([5] returned 401). The agent filled gaps with web search and prior knowledge, delivering a substantive answer grounded in external sources rather than direct site navigation.

• ›Fetch [1] (homepage) and [6] (/about) returned only truncated HTML with no substantive content visible; the site appears to be client-rendered and login-gated, making it opaque to direct crawling.
• ›Fetch [5] (/pricing) returned a 401 error ('请重新登陆' / 'please re-login'), confirming that pricing and likely other core information requires authentication.
• ›Steps [9] (ToolMage), [19] (AIWW), [20] (UISDCd.design), and [24] (Baidu wiki) provided the actual content—feature lists, positioning, freemium model details, and comparisons to Canva/Figma. None originated from the official d.design domain itself.
• ›The agent correctly identified that d.design is Alibaba's 'DuiYou' platform (Chinese name 堆友) and pivoted to Chinese-language search terms ([17]) to surface better documentation, demonstrating adaptive discovery.
• ›The site publishes minimal machine-readable information in its HTML headers or meta tags; understanding d.design required relying on third-party aggregators and review sites, not official documentation.
• ›The agent could not access or verify exact paid pricing tiers, exact AI model capabilities, or concrete examples of 'AI Agent' and 'Skills' workflows—these remain unavailable without account login.
