WHY IT NEEDS A POLICY

Why save_presentation needs a policy

This tool performs a write operation that creates or modifies data (Keynote presentation files) on the filesystem. It is reversible—saved files can be edited, overwritten, or deleted by subsequent operations. It does not delete data irreversibly (ruling out Destructive) nor does it execute arbitrary code (ruling out Execute).

From the tool's definition Tool description states 'Saves the frontmost Keynote presentation. Optionally specify a file path for save-as.' The save and save-as operations create or modify presentation files on disk.
