Rubber Duck - Debugging Companion

The Rubber Duck skill is designed to assist users who are stuck or debugging code. It implements a 'Quack Protocol' that guides the user through a series of steps: first, restating the problem in a single sentence to ensure understanding; second, inventorying all previously attempted solutions and their outcomes; third, surfacing and verifying implicit assumptions made about the problem; and finally, asking one single, focused question to help the user gain clarity. The skill strictly avoids proposing solutions until the user has had an opportunity to identify the issue themselves, aiming to foster independent problem-solving.
