AI agent misled by deceptive web pages, highlighting need for better checks

An AI agent was misled by a website that returned a 200 status code for non-existent pages, providing only an empty JavaScript shell instead of actual content. This highlights three ways a web page can be deceptive: serving an empty shell, delivering stale content despite a successful build, or accidental overwriting of downloaded files during checks. To mitigate these issues, the author proposes implementing a control mechanism where a request for a non-existent page is made alongside the actual page request to verify the server's ability to distinguish pages. Additionally, a content check is recommended to ensure the page contains specific, expected information, such as a product title or version stamp. AI
