WHY IT NEEDS A POLICY

Why create_plane_issue needs a policy

This tool creates new project management data (issues) which is reversible through deletion or modification. It has Write semantics as it adds structured data to an external system. Severity is medium because misuse could create spam issues or corrupt project organization, but the blast radius is limited to the specific project and the action is reversible.

From the tool's definition Tool name 'create_plane_issue' and description 'Create a new issue in a Plane project' explicitly indicate creation of new data in a project management system.
