Is Using a Service for Dependency Injection an Anti-Pattern in Effect Typescript?

export class WorkspaceOpsService extends Context.Tag(
  "@mason/workspace/WorkspaceOpsService"
)<
  WorkspaceOpsService,
  {
    checkSlug: (
      params: WorkspaceCheckSlugRequest
    ) => Effect.Effect<
      WorkspaceCheckSlugResponse,
      WorkspaceSlugAlreadyExistsError | MasonError
    >;
  }
>() {
  static readonly live = Layer.effect(
    WorkspaceOpsService,
    Effect.gen(function* () {
      const workspaceRepo = yield* WorkspaceRepository;

      return WorkspaceOpsService.of({
        checkSlug: (params) =>
          WorkspaceCheckSlugAction(params).pipe(
            Effect.provideService(WorkspaceRepository, workspaceRepo),
            Effect.catchTags({
              "shared/DatabaseError": (e) =>
                Effect.fail(new MasonError({ cause: e })),
            })
          ),
      });
    })
  );
}
