WHY IT NEEDS A POLICY

Why convertExcelToSheets needs a policy

The tool creates a new Google Sheets file derived from an Excel file. This is a write operation because it generates new data (the converted sheet) without destructively altering the original. The severity is low because: (1) the original file remains untouched, (2) the operation is reversible (the converted file can be deleted), and (3) no data loss or external side effects occur.

From the tool's definition Tool 'convertExcelToSheets' creates a copy of a file in a new format ('Creates a copy; the original is preserved'). This is a reversible data creation/modification operation.
