Implementation Reference

• handlers/tasks.ts:158-171 (handler)

  The main handler function that validates input arguments using isDeleteTaskListArgs and delegates to the GoogleTasks instance's deleteTaskList method to perform the deletion.

  export async function handleTasksDeleteTasklist(
    args: any,
    googleTasksInstance: GoogleTasks
  ) {
    if (!isDeleteTaskListArgs(args)) {
      throw new Error("Invalid arguments for google_tasks_delete_tasklist");
    }
    const { taskListId } = args;
    const result = await googleTasksInstance.deleteTaskList(taskListId);
    return {
      content: [{ type: "text", text: result }],
      isError: false,
    };
  }

• utils/tasks.ts:237-251 (helper)

  The core implementation in the GoogleTasks class that calls the Google Tasks API to delete the specified task list.

  async deleteTaskList(taskListId: string) {
    try {
      await this.tasks.tasklists.delete({
        tasklist: taskListId,
      });
  
      return `Task list ${taskListId} deleted.`;
    } catch (error) {
      throw new Error(
        `Failed to delete task list: ${
          error instanceof Error ? error.message : String(error)
        }`
      );
    }
  }

• tools/tasks/index.ts:186-199 (schema)

  The tool definition including name, description, and input schema for validation.

  export const DELETE_TASKLIST_TOOL: Tool = {
    name: "google_tasks_delete_tasklist",
    description: "Delete a task list",
    inputSchema: {
      type: "object",
      properties: {
        taskListId: {
          type: "string",
          description: "ID of the task list to delete",
        },
      },
      required: ["taskListId"],
    },
  };

• server-setup.ts:258-262 (registration)

  The switch case in the main server request handler that routes calls to this tool to its handler function.

  case "google_tasks_delete_tasklist":
    return await tasksHandlers.handleTasksDeleteTasklist(
      args,
      googleTasksInstance
    );

• utils/helper.ts:412-416 (schema)

  Type guard function used in the handler to validate input arguments matching the tool schema.

  export function isDeleteTaskListArgs(args: any): args is {
    taskListId: string;
  } {
    return args && typeof args.taskListId === "string";
  }
