Use this skill whenever the user wants to understand, analyze, or audit a codebase before refactoring. Triggers include: "analyze this project", "what does this codebase do", "give me an overview of the code", "audit dependencies", "map the file structure", "what are the code smells", "assess code quality", "review this project", "what needs refactoring", or any request to understand a codebase before changing it. Also triggers when a user shares a project folder and wants to know where to start. Do NOT use for actually writing refactored code — use refactor-code for that.
