WHY IT NEEDS A POLICY

Why export_svg needs a policy

This tool creates or writes files to persistent storage. While the action itself is reversible (exported files can be deleted or overwritten), it modifies the user's filesystem by creating new files. This is a Write operation rather than Destructive because the export does not irreversibly delete or overwrite existing data—it simply creates new output.

From the tool's definition Tool name is "export_svg" and description states "SVG 파일로 내보냅니다" (exports to SVG file). The tool exports/saves SVG graphics to a file.
