WHY IT NEEDS A POLICY

Why tms_create_project needs a policy

This tool creates a new project resource in the Phrase TMS system, which is a reversible modification (projects can be deleted). It requires Project Manager permissions, indicating elevated access is needed. The blast radius is high because creating projects could impact organizational localization workflows, resource allocation, and potentially incur costs through project setup and management overhead.

From the tool's definition Tool name contains 'create' and description states 'Create a new Phrase TMS project from scratch'. The endpoint is POST /api2/v3/projects, a standard write operation.
