WHY IT NEEDS A POLICY

Why notion_table_update_cells needs a policy

The tool modifies existing database/table content by updating row cells. It is reversible (updates can be undone or overwritten), so it falls under Write rather than Destructive. The scope is limited to a single row within a table, reducing blast radius compared to database-wide operations. Severity is medium because unintended row updates could corrupt structured data, but the effect is contained and recoverable.

From the tool's definition Update all cells in a table row. Replaces entire row content — indicates modification of existing data in Notion tables.
