The agent successfully fulfilled the task by assembling a complete explanation of iCost Analyzer from GitHub-hosted sources rather than the website itself. The site (icost.lmmmmmm.dev) is minimally navigable for discovery—it serves as a React app frontend with no visible documentation, forcing the agent to rely entirely on the GitHub repository README and package.json to answer what the product does, who it's for, its pricing, and how it differs from alternatives.

• ›The website itself (steps [1], [4]) returned only HTML scaffolding and JavaScript bundles with no machine-readable content answering the task; the site is a thin client with no landing page copy, pricing information, or feature documentation embedded in its HTML.
• ›All substantive answers came from GitHub sources ([15] the API-fetched README content in base64, [16] the raw README markdown, [17] package.json for technical stack)—the agent had to infer that the GitHub repo was authoritative by discovering it through web search and GitHub API queries, rather than finding links on the website itself.
• ›The website offers no entry point for understanding the product: no about page, no documentation link, no metadata in HTML head tags (title is only 'iCost Analyzer｜本地账单分析' in Chinese); the site assumes users already know what to do and how to use it, making it unsuitable as a standalone discovery or educational resource.
