Review Summary

Your implementation correctly handles the core file copying functionality using fs.copyFileSync, properly skips operations when source and destination are identical, and uses console.error() for error output as required. There's one improvement worth noting: the argument validation for missing input parameters should be moved outside the path-equality check. Currently, when no arguments are provided, the condition source !== destination evaluates to false (since both are undefined), which bypasses the validation entirely and results in silent failure. Adding a check like if (!source || !destination) before comparing paths would give users proper feedback. This is a non-blocking issue since the core functionality works correctly for valid inputs, but addressing it would make the tool more robust for edge cases.
