WHY IT NEEDS A POLICY

Why knowledge_create_dataset needs a policy

Creating a knowledge base is a write operation that modifies the state of the system by adding new data structures, but it is reversible (the dataset can be deleted). It does not execute arbitrary code, delete irreversibly, move money, or merely read data.

From the tool's definition Tool name 'knowledge_create_dataset' and description 'Create a new knowledge base' indicate data creation. This is a reversible write operation that adds a new dataset/knowledge base to the Dify instance.
