improve-codebase-architecture

Use this skill to refactor, clean up, and improve a codebase or specific folder. Trigger when the user asks to: improve code architecture, clean up AI-generated slop, refactor for readability, make code more testable, reduce complexity, improve folder structure, apply clean architecture principles, separate concerns, increase modularity, add helpful comments, apply DRY principles, split large files, or generally improve code quality. Also trigger for phrases like "clean up my code", "review my codebase", "make this more readable", "reduce complexity", "refactor this", "improve my project structure", "audit my code", "restructure this project", "separate concerns", "make this more modular", or "apply clean architecture". The skill conducts a structured interview before making any changes, exploring every design decision collaboratively, then delivers both an architecture description and fully refactored code (including a new folder structure if warranted). Always use this skill rather than ad-hoc refactoring.
