WHAT IT DOES

WHY IT NEEDS A POLICY

Why create_user needs a policy

This tool creates new user accounts in the project management system. While reversible (users can be deleted), creating users has significant implications for access control and system usage. The 'admin only' restriction indicates this is a privileged operation. It falls under Write rather than Execute because it directly creates data rather than running arbitrary code.

From the tool's definition Tool name 'create_user' and description 'Create a new user (admin only)' indicate this creates a new user account in OpenProject, a reversible write operation.
