RISK

Why GOOGLESUPER_ADD_SHEET is rated Medium

This tool creates new worksheets within existing spreadsheets, which is a reversible modification operation. It falls under Write category since sheets can be deleted or renamed if created in error. Severity is medium because while it modifies user data structures, the changes are non-destructive and reversible, and the blast radius is limited to a single spreadsheet's structure.

From the tool's definition Tool description explicitly states it 'Adds a new sheet (worksheet) to a spreadsheet' and 'create a new tab within an existing Google Sheet', which are create operations that modify spreadsheet structure reversibly.
