Implementation Reference

• main.ts:776-801 (registration)

  Registration of the 'taskStepDelete' MCP tool, including description, Zod input schema, and thin async handler that delegates to TaskManagerTool.deleteTaskStep and handles response formatting.

  server.tool("taskStepDelete",
      "刪除任務的特定步驟",
      {
          taskId: z.string(),
          stepId: z.string()
      },
      async ({ taskId, stepId }) => {
          try {
              const updatedTask = await TaskManagerTool.deleteTaskStep(taskId, stepId);
  
              if (!updatedTask) {
                  return {
                      content: [{ type: "text", text: `未找到指定的任務或步驟` }]
                  };
              }
  
              return {
                  content: [{ type: "text", text: `步驟刪除成功：\n${JSON.stringify(updatedTask, null, 2)}` }]
              };
          } catch (error) {
              return {
                  content: [{ type: "text", text: `刪除步驟失敗: ${error instanceof Error ? error.message : "未知錯誤"}` }]
              };
          }
      }
  );

• tools/taskManagerTool.ts:314-345 (handler)

  Core handler logic for deleting a task step: loads tasks, finds task, filters out the step by ID, reorders remaining steps, updates timestamp, and persists changes to storage.

  public static async deleteTaskStep(taskId: string, stepId: string): Promise<Task | null> {
    const tasks = await this.readTasks();
    const taskIndex = tasks.findIndex(t => t.id === taskId);
  
    if (taskIndex === -1) {
      return null;
    }
  
    const task = tasks[taskIndex];
    const initialStepsLength = task.steps.length;
  
    // 刪除步驟
    task.steps = task.steps.filter(s => s.id !== stepId);
  
    if (task.steps.length === initialStepsLength) {
      return null;
    }
  
    // 重新排序步驟
    task.steps = task.steps.map((step, index) => ({
      ...step,
      order: index + 1
    }));
  
    // 更新任務
    task.updatedAt = new Date().toISOString();
  
    // 保存所有任務
    await this.writeTasks(tasks);
  
    return task;
  }

• main.ts:778-781 (schema)

  Zod schema defining input parameters: taskId (string) and stepId (string).

  {
      taskId: z.string(),
      stepId: z.string()
  },
