WHY IT NEEDS A POLICY

Why create_issue needs a policy

This tool creates new issues (data) in OverlayQA projects. While reversible (issues can typically be deleted or modified), it modifies the state of a project by adding new records. This is a Write operation—it creates data without the ability to undo automatically and without destructive side effects.

From the tool's definition Tool description states 'Create an issue in an OverlayQA project', which is explicitly creating and persisting new data in a project management system.
