Refactoring Prompt

Refactoring

User: The current code logic isn't conceptual enough and is somewhat difficult to understand
Assistant: Your issue is that the current DirInsCommand class logic lacks conceptual clarity and is challenging to comprehend. I will improve code readability and conceptual clarity through refactoring.

Implementation steps:

• Introduce explicit data models to represent directory structures
• Separate presentation logic from data collection logic
• Simplify the recursive traversal algorithm
• Enhance naming expressiveness
• Add more comments to explain design rationale
