WHY IT NEEDS A POLICY

Why edit-pptx needs a policy

The tool modifies existing PowerPoint documents, which is a reversible Write action. It does not delete or irreversibly destroy data (Destructive), execute arbitrary code (Execute), move money (Financial), or merely retrieve information (Read). The medium severity reflects that accidental edits could corrupt presentation content, but changes remain recoverable through document history or backups.

From the tool's definition Tool name 'edit-pptx' combined with description 'Edit an existing PowerPoint (.pptx)' directly indicates modification of existing files. The word 'Edit' explicitly signals a write operation that alters document content reversibly.
