WHY IT NEEDS A POLICY

Why create_project needs a policy

Creating a project in a task management system is a reversible write operation—it adds data to the user's task database but does not delete, execute code, or trigger financial transactions. The lack of a detailed description slightly reduces confidence, but the tool name and server context clearly indicate data creation.

From the tool's definition Tool name 'create_project' indicates creation of a new project entity in Things3 task manager. Server description confirms 'write access' capability.
