WHY IT NEEDS A POLICY

Why split_pdf needs a policy

Splitting a PDF typically creates new files from an existing one, which is a Write operation (creating new documents). The original file may or may not be modified depending on implementation. Since the description is empty, confidence is reduced, but 'split' generally implies creating new output files rather than destructive modification.
