WHY IT NEEDS A POLICY

Why create_data_list needs a policy

This tool creates new data structures in AdButler's system, which is a reversible write operation. While it modifies state by adding new data lists, it does not execute arbitrary code, delete data, move money, or trigger external operations. Severity is medium because inappropriate data list creation could clutter the system or store unwanted data, but the impact is limited and reversible.

From the tool's definition Tool name 'create_data_list' and description 'Create a new data list' indicate data creation. Context shows AdButler manages advertising campaigns and data.
