WHY IT NEEDS A POLICY

Why save_pdf needs a policy

The tool creates or writes PDF files to persistent storage, making it a Write category action. Severity is medium because misuse could fill disk space, overwrite user files, or store sensitive utility/consumption data in unintended locations, but it is reversible (files can be deleted). Confidence is 0.85 rather than higher due to empty description providing no explicit confirmation of side effects.

From the tool's definition Tool name 'save_pdf' indicates file creation/storage operation. Server context shows it handles utility consumption reports and PDF downloads, suggesting this tool persists files to storage.
