WHY IT NEEDS A POLICY

While it alters existing data, the operation is not permanent/unrecoverable — data can be edited, undone, or restored. The severity is high because an AI agent with access could overwrite critical spreadsheet data across multiple cells, affecting business logic, analytics, or dependent workflows.

From the tool's definition Tool name contains 'write' and description states 'Write data to a specific range in a Google Sheet' — directly modifies spreadsheet content.
