WHY IT NEEDS A POLICY

Why sheets_insert_date needs a policy

The tool inserts or writes date values into spreadsheet cells. While this modifies data, it is reversible (values can be edited or cleared afterward), placing it in the Write category rather than Destructive. Severity is medium because misuse could corrupt data integrity or overwrite important date fields, but the impact is limited to insertions that users can undo.

From the tool's definition Tool name 'insert' and description 'Insert properly formatted dates' indicate creation/modification of cell data in Google Sheets. This is reversible modification, not deletion or irreversible destruction.
