Why spreadsheet_export_csv is rated Medium
Export operations typically generate new files or data artifacts. While not destructive (reversible), and not a read-only query, this falls under Write category as it creates/outputs data. Severity is medium because exporting spreadsheet data has moderate blast radius—unintended exports could leak sensitive design data or create unwanted files, but the operation is reversible.
From the tool's definition Tool name 'spreadsheet_export_csv' indicates export functionality that creates or writes CSV data, likely saving to file or output stream.
