refactor-safe

Execute the following steps:

1. Check if current directory is a valid project (package.json, requirements.txt, etc.)

2. Analyze code patterns and identify safe refactoring opportunities:

   • Duplicate code blocks that can be extracted into functions
   • Long functions that can be broken down
   • Magic numbers/strings that should be constants
   • Unused imports or variables
   • Simple type improvements (TypeScript/Python)
   • Dead code that can be removed safely

3. Prioritize suggestions by safety level:

   • Safe: No behavior change (extract constants, remove unused code)
   • Low Risk: Mechanical refactoring (extract functions, rename variables)
   • Medium Risk: Structural changes that need testing
