-View git diff between the branch i specified and HEAD. If no branch is specified,

-unused variables etc. Think twice before removing or adding code, because you 
-mustn't alter the behavior.
+# Code Cleanup Command
+
+## Overview
+Analyze git diff between the specified branch and HEAD (defaults to main if no branch specified) and clean up code quality issues without altering functionality.
+
+## Process
+1. **Get diff**: Run `git diff <branch>..HEAD` to see changes
+2. **Identify issues**: Look for code quality problems in the diff
+3. **Clean up**: Remove only the identified issues
+4. **Verify**: Ensure no behavioral changes
+
+## What to Clean Up
+- **Debug artifacts**: `console.log()`, `debugger`, `print()` statements
+- **Unused code**: Variables, imports, functions, parameters
+- **Commented code**: Dead code blocks, TODO comments (unless active)
+- **Formatting**: Inconsistent spacing, trailing whitespace
+- **Temporary code**: Test values, hardcoded strings meant to be dynamic
+- **Redundant code**: Duplicate logic, unnecessary intermediate variables
+
+## What NOT to Touch
+- **Functional logic**: Don't change how features work
+- **API interfaces**: Keep method signatures intact
+- **Configuration**: Don't modify settings or constants
+- **Comments**: Keep documentation and explanatory comments
+- **Error handling**: Don't remove try-catch blocks or validation
+
+## Safety Rules
+- ✅ Only modify code that appears in the git diff
+- ✅ Preserve all existing functionality
+- ✅ Maintain code readability and structure
+- ❌ Don't refactor or optimize beyond cleanup
+- ❌ Don't add new features or improvements
+- ❌ Don't change variable names or function signatures
+
+## Example
+```bash
+# If user specifies: "/clean-up main"
+git diff main
+# Clean only the issues found in this diff
+```

 - Use double quotes ("") for strings consistently.
 - Prefer functional components over class components in React.
