Quackula: A Haunted Rubber Duck That Hunts Code Smells and Asks the Hard Questions

Quackula is a developer tool described as a haunted rubber duck that lives in the terminal and browser. Its exorcise mode scans a repository for problematic code patterns such as swallowed exceptions, oversized functions, and leftover debug logging, then explains in plain English how to fix each one. A separate debug mode follows the classic rubber-duck approach, prompting the user with pointed questions instead of giving direct answers. The author presents the project as a submission to a Hacktoberfest AI challenge and frames it as a nod to the long-standing rubber-duck debugging tradition. A demo on a deliberately flawed sample project showed thirteen detected issues, each accompanied by a stylized verdict.
