WHY IT NEEDS A POLICY

Why create_spreadsheet needs a policy

Creating a new spreadsheet is a write operation: it modifies the user's Google Sheets environment by adding a new resource. However, it is not destructive (the spreadsheet can be deleted), not financial (no money involved), and not execute (no code execution or external triggers).

From the tool's definition Tool creates a new spreadsheet, which is a reversible operation that adds data to Google Sheets infrastructure. The verb 'create' with a new resource is characteristic of Write operations.
