• [nitpick] The JSON property name isChild mixes camelCase with other snake_case properties; consider using is_child for consistency with occurrence_count.

        [JsonProperty(propertyName: "isChild")]

Contentstack.Management.Core/Models/ContentModelling.cs:16

• New Description property is not covered by existing unit tests; consider adding deserialization tests to verify it and the GlobalFieldRefs list are correctly populated.

        [JsonProperty(propertyName: "description")]

Contentstack.Management.Core/Models/GlobalFieldRefs.cs:10

• [nitpick] Class name GlobalFieldRefs is plural but represents a single reference; consider renaming to GlobalFieldRef for clarity.

    public class GlobalFieldRefs
