WHY IT NEEDS A POLICY

Why create_object_schema needs a policy

This tool creates a custom object schema (metadata/structural definition) in the GoHighLevel CRM system. Schema creation is a Write operation because it establishes new data structures that can subsequently be modified or removed. While it affects system configuration, it is reversible (schemas can be updated or deleted), distinguishing it from Destructive actions.

From the tool's definition Tool description states 'Create a new custom object schema' - the verb 'create' indicates creation of a new data structure that can be modified or deleted later, making it a reversible write operation.
