WHY IT NEEDS A POLICY

Why open-presentation needs a policy

This tool performs a Write operation by creating a backup copy of an existing presentation file. It does not delete, execute arbitrary code, or cause irreversible changes. The blast radius is low since creating a backup copy is a standard, non-destructive operation that can be easily undone or managed.

From the tool's definition The tool description states it 'Opens an existing presentation and saves a copy to a new file for backup.' The action of saving a copy to a new file constitutes creating/modifying data reversibly.
