WHY IT NEEDS A POLICY

Why pptx_create needs a policy

This tool creates a new PowerPoint presentation file, which is a reversible write operation. It does not execute code, delete data, or commit financial transactions. The blast radius is minimal—a new blank file can be easily deleted if created in error. Severity is low because creating a blank presentation has negligible potential for harm even in adversarial use.

From the tool's definition Tool description states 'Create a new blank PPTX file', which is a write operation that creates new data without destructive or executable side effects.
