Brainstorm a topic to generate Python class skeletons with real-world functions. Use this skill whenever a user wants to design a class structure, architect an object-oriented system, or generate Python skeleton code with attributes and methods. Trigger on phrases like "generate a skeleton for X", "create a class structure", "design this as a class", "let's brainstorm X", or any request to turn a concept into Python code with getter/setter methods and business logic functions.
