WHY IT NEEDS A POLICY

Why set_row_color needs a policy

This tool modifies metadata (row color) associated with Pinako's organizational nodes (groups and folders). It is not destructive since color changes are reversible and can be undone. It does not execute code or trigger external operations. It is a Write operation because it creates or modifies data in a reversible manner.

From the tool's definition The tool "sets the rowColor of a Pinako Group node or Folder node," which modifies display properties of organizational elements within the Pinako extension. This is a reversible data modification operation.
