WHY IT NEEDS A POLICY

Why create_workflow_run needs a policy

This tool creates a new workflow run record in draft status, which is a reversible write operation. It does not execute tasks, delete data, or move money. The severity is medium because creating workflow runs could consume resources or trigger downstream automation if not properly constrained, but the draft status suggests it's not immediately active.

From the tool's definition Tool name 'create_workflow_run' and description 'Create a new workflow run in draft status' indicates creation of a new data entity.
