# Problem Statement `client-go` package currently lacks support for updating individual, bulk list of Work Items & hierarchical re-ordering of Work Items. ### Proposed Solution Create a new `WorkItemsService` with: * **Pre-defined data structures** matching common work item fields and operations * **High-level functions** (`UpdateWorkItem(), BulkUpdateWorkItems(), ReorderWorkItems()`) that abstract away GraphQL query construction * **Automatic type conversion** from GraphQL response types to idiomatic Go types * **Consistent API patterns** following the conventions established by `IssuesService` and other existing services ### docs: * [Mutation.workItemUpdate](https://docs.gitlab.com/api/graphql/reference/#mutationworkitemupdate) * [Mutation.workItemsBulkUpdate](https://docs.gitlab.com/api/graphql/reference/#mutationworkitemsbulkupdate) * [Mutation.workItemsHierarchyReorder](https://docs.gitlab.com/api/graphql/reference/#mutationworkitemshierarchyreorder)
