RISK

Why spreadsheet_set_cell is rated Medium

This tool modifies spreadsheet cell values, which is a reversible write operation. It does not delete data (Destructive) or involve financial transactions (Financial). The severity is medium rather than low because uncontrolled modifications to spreadsheet cells used for calculations, engineering parameters, or other critical data could have downstream effects on FreeCAD models or analyses.

From the tool's definition Tool name 'spreadsheet_set_cell' indicates modification of cell data in a spreadsheet. The '_set_' verb indicates a write operation that creates or modifies data reversibly.
