Step 2015

以下有几个部分：
ROLE_AND_TASK：你的角色定义以及任务描述
TOOLS：你可以调用的工具列表，以及每个工具的参数说明
OUTPUT：输出相关规则和约束
TIPS：重要建议
SITUATION：操作历史和任务相关状态

<ROLE_AND_TASK>
你是一个计算机操作代理，正在操作 Ubuntu Linux 桌面。你可以通过截图查看屏幕，并使用鼠标和键盘动作来控制它。

你的任务是：借助工具，来操作一台电脑来达成任务: Add page number for every page at the bottom left。
电脑的操作系统: Ubuntu Linux

工作流程：
1. 理解当前的情况（SITUATION），SITUATION 中会包括策略树状态、任务失败条件列表、关键视觉证据、上次返回的操作、屏幕截图（上次操作前 & 上次操作后）、历史操作简述。
2. 思考如何尽快达成任务，规划接下来的动作。可以是1次动作，也可以是一组BATCH动作。BATCH动作原则见下。
3. 输出tool_calls：包含你规划的需要执行的电脑操作以及维护 SITUAION 的工具调用。
4. 重复上面步骤，直到任务达成。

关于策略树：
- 策略树是一个分层的任务管理结构。
- 它可以帮助你组织和跟踪任务所需的步骤。也可以帮助你在某个细分尝试方向失败时，回退到高级的节点来尝试其他方法。通过维护策略树，你可以系统地分解复杂任务，并且在较困难的子任务中大胆尝试，确保每一步都得到适当的关注和执行。
- 策略树必须以层次结构组织，实例：
`1`: 顶层任务。重要目标或里程碑，从用户给出的任务开始拆解。
`1.1`, `1.2`, ...: 任务 `1` 的子任务。
`1.1.1`, `1.1.2`, ...: 任务 `1.1` 的子任务或尝试路径方案。它们不是实际动作，而是对父任务的子目标贡献。

关于失败条件列表：
- 失败条件列表是一个 checklist
- 它用于辨认当前任务是否还有达成的可能。当所有失败条件都被确认为真后，任务将返回不可能达成。

关于关键视觉证据：
- 关键视觉证据是一些屏幕状态的描述，这些状态可以通过截图来验证。
- 任务完成后，验证模块会检查这些视觉证据是否都满足，以判断任务是否成功完成。

</ROLE_AND_TASK>

<TOOLS>
你拥有以下工具：computer、update_strategy_tree。
每次调用必须包含computer工具的调用来执行电脑操作，update_strategy_tree工具的调用则根据需要选择性使用来维护策略树状态。

## computer
操作电脑的动作库，调用它以在桌面上执行操作。

坐标值定义：
在最新一张屏幕截图中的坐标轴比例，使用 [0, 1] 范围内的归一化值。其中 (0, 0) = 屏幕左上角，(1, 1) = 屏幕右下角。

操作和参数说明：
1. 移动鼠标
{
  "action": "mouse_move",
  "to_coordinate": [float, float], # 移动到的坐标值。
}

2. 移动鼠标并点击鼠标按键
{
  "action": str, # 鼠标按键操作，one of left_click | right_click | middle_click | double_click | triple_click
  "at_coordinate": [float, float], # 移动到的坐标值。
  "with_key": str or None, # 点击时按住的键盘按键(比如"ctrl"、"shift")，如没有则填None。
}

3. 按住鼠标左键并拖动
{
  "action": "left_click_drag",
  "from_coordinate": [float, float], # 起始到的坐标值,
  "to_coordinate": [float, float], # 移动到的坐标值。
  "with_key": str or None, # 点击时按住的键盘按键(比如"ctrl"、"shift")，如没有则填None。
}

4. 输入文字
{
  "action": "type",
  "text": str, # 要输入的文字
  "submit": bool, # 输入后是否按 Enter 键提交
}

5. 键盘按键（单个或组合键）
{
  "action": "key",
  "text": list[str], # 要按的键盘按键组合(如"enter"、"tab"、"ctrl"),
  "with_duration": float or None, # 按键持续时间（秒），如点击则填 null。
}

6. 移动鼠标并滚动鼠标滚轮
{
  "action": "scroll",
  "at_coordinate": [float, float], # 滚动位置的坐标值
  "scroll_direction": str, # 滚动方向，one of "up" | "down" | "left" | "right"
  "scroll_amount": int, # 滚动量，1-30，模拟人类滚轮滚动的幅度。较大的值表示更大幅度的滚动。
}

7. 等待
{
  "action": "wait",
  "duration": float, # 等待秒数。根据操作后界面变化的复杂程度调整等待时间。
}


BATCH动作原则：
BATCH动作指一组连续且相对固定的电脑操作，主要用来减少不必要的对话过程。
- 例如：顺序输入（type→Tab→type）、键盘快捷键（Ctrl+C 然后 Ctrl+V）、输入一段字符后 Enter（在搜索输入框中常用）。
- DO NOT BATCH：涉及界面状态变化等待的操作（如打开菜单/对话框后等待动画）→ 依赖新坐标的操作。例如：点击打开一个菜单后，等待菜单完全展开再点击菜单项，因为菜单项的坐标在菜单完全展开前可能不稳定；滚动页面后再点击某个元素，因为滚动会改变元素的坐标。
**只在比较确定的操作中可以使用多个动作组合。当你不确定时，使用单个动作是更保险的做法**

## update_strategy_tree
维护策略树的相关工具

1. 创建新任务节点
{
  "action": "create",
  "parent_id": str or None, # 父任务ID，根任务则填None。此操作会在这个父节点下顺序创建子节点。
  "description": str, # 任务描述
}

2. 更改节点状态
{
  "action": "change_status",
  "id": str, # 任务ID，使用点号分隔的层次编号（如 1.2.1），程序会自动解析层级关系。
  "new_status": str, # 新状态，one of None | "success" | "fail"
  "fail_reason": str or None, # 失败原因，仅在 new_status=fail 时需要提供
}
</TOOLS>

<OUTPUT>
你需要调用工具来规划接下来需要执行的电脑操作，以及维护SITUATION（如果需要）。
另外你需要输出从最新的屏幕截图中观察到的重要信息、你对当前情况的分析、为什么这么做的思考过程（thoughts）。

</OUTPUT>

<TIPS>
- 尽量以最少的操作数完成任务。每个动作都应该有明确的目的，并直接推动任务向前发展。
- 优先操作成功率，其次是操作的效率。
- 尽可能使用键盘快捷键（例如 ctrl+l 聚焦浏览器地址栏），以增加操作的成功率。
- 如果一段时间的多个动作后还未产生预期结果，参考策略树中其父节点的目标并尝试替代路径。
- 始终记得完成时保存文件（例如 ctrl+s），除非任务明确说不需要。
- 永远不要假设操作成功。寻找预期变化的具体视觉证据。
- 如果截图与上一张相同，说明上一次操作没有产生任何效果。不要假设它成功——诊断为什么失败并尝试不同的方法。
</TIPS>

<SITUATION>
SITUATION中有4个部分：策略树状态、上次返回的操作、屏幕截图（上次操作前 & 上次操作后）、历史操作简述

## 1. 策略树状态
1: Open the Insert menu to access Footer options
  1.1: Click on Insert menu in the menu bar
  1.2: Select Footer option to enable footer for all pages
  1.3: Choose Default Page Style to apply footer to the document
2: Insert and position page number field in footer
  2.1: Click in the footer area at the bottom of the page
  2.2: Click Insert menu > Page Number to add page number field
  2.3: Select the page number and align it to the left (bottom left)
3: Verify page numbers appear on all pages at bottom left

## 2. 任务失败条件检查
- LibreOffice Writer is not installed or not accessible
- The document is read-only or password protected
- No permission to modify the document

## 3. 关键视觉证据
- 页脚区域在页面底部可见，且左下角显示页码数字（如'1'）
- 第二页的左下角显示页码'2'，证明每页都有页码
- 页码位于页面底部左侧（左对齐）
- 页脚中的页码为自动更新的字段格式，非手动输入的静态文本

## 4. 上一次返回的决策

### 4.1. 上一次的观察和思考
```
#### 重要信息

An "Edit Fields" dialog box has appeared, which was triggered by the previous triple-click action on the page number. This dialog allows editing the page number field format, but I don't need to change the format - I just need to align the existing page number to the left. The dialog shows:
- Type: "Page number" is selected
- Various format options (First, Second, Third..., Roman numerals, etc.)
- Offset field set to "0"
- Help, Cancel, and OK buttons

I need to close this dialog first to get back to the document, then properly align the page number to the left.

#### 情况分析与思考过程

The Edit Fields dialog appeared because the triple-click selected the page number field and triggered the field editing mode. To complete the task:
1. Close this dialog by clicking "Cancel" (since I don't need to change the field format)
2. Return to the document with the footer active
3. Select the page number text in the footer
4. Apply left alignment to move it to the bottom left

I'll click the "Cancel" button to close this dialog and return to the document.
```

### 4.2. 上一次返回的操作
{"function": {"name": "computer", "arguments": {"actions": [{"action": "left_click", "at_coordinate": [0.616, 0.706]}]}}}

### 步骤 9:
- 描述:
  ```
  #### 重要信息
  
  The previous action closed the Insert menu, and I can now see that a page number "3" has been inserted in the footer. However, the page number appears to be centered in the footer rather than aligned to the left (bottom left) as required by the task. The footer is active and the page number field is visible.
  
  #### 情况分析与思考过程
  
  The page number has been successfully inserted in the footer, but it's currently centered. According to the task requirements, I need to align it to the bottom left. My next steps are:
  1. Click on the page number to select it
  2. Use the left alignment button in the toolbar to align it to the left
  
  I can see the page number "3" in the footer area. I'll click on it to select the page number field, then align it to the left using the alignment buttons.
  ```
  
  I'll click on the page number in the footer to select it, then align it to the left.
- 操作:
  1. 左键单击坐标 (0.338, 0.736)

### 步骤 10:
- 描述:
  ```
  #### 重要信息
  
  The page number "3" in the footer is now selected (I can see the selection indicator around it). The page number is currently centered in the footer area. I need to align it to the left to meet the task requirement of placing page numbers at the bottom left of every page.
  
  #### 情况分析与思考过程
  
  The previous action successfully selected the page number field in the footer. Now I need to:
  1. Click the left alignment button in the toolbar to align the page number to the left
  2. After alignment, click outside the footer to exit footer editing mode
  3. Verify the page number appears at the bottom left
  4. Save the document
  
  I can see the alignment buttons in the toolbar. The left alignment button is visible in the formatting toolbar. I'll click on it to align the page number to the left.
  ```
- 操作:
  1. 左键单击坐标 (0.555, 0.134)

### 步骤 11:
- 描述:
  ```
  #### 重要信息
  
  The previous attempt to click the left alignment button at coordinates [0.555, 0.134] didn't seem to work - the page number "3" is still centered in the footer. I can see the page number is visible in the footer area, but it needs to be properly selected first before applying alignment.
  
  #### 情况分析与思考过程
  
  The alignment didn't change because either:
  1. The page number wasn't properly selected when the alignment button was clicked
  2. The coordinates for the alignment button were incorrect
  
  I need to:
  1. First, click directly on the page number "3" in the footer to select it
  2. Then click the left alignment button in the toolbar
  
  Looking at the footer, I can see the page number "3". I'll click on it to select it first, then apply left alignment.
  ```
- 操作:
  1. 左键单击坐标 (0.338, 0.736)

### 步骤 12:
- 描述:
  ```
  #### 重要信息
  
  The page number "3" is visible in the footer area. The previous action attempted to select it, and now I need to apply left alignment to move it to the bottom left as required. I can see the alignment buttons in the toolbar - the left alignment button should align the selected content to the left.
  
  #### 情况分析与思考过程
  
  The page number appears to be in the footer but still centered. I need to:
  1. Apply left alignment using the left alignment button in the toolbar
  2. The left alignment button should be among the alignment buttons visible in the formatting toolbar
  3. After alignment, verify the page number moves to the left side of the footer
  
  Looking at the toolbar, I can see alignment buttons. I'll click on the left alignment button to align the page number to the left.
  ```
- 操作:
  1. 左键单击坐标 (0.555, 0.134)

### 步骤 13:
- 描述:
  ```
  #### 重要信息
  
  The previous attempt to click the left alignment button didn't work - the page number "3" is still centered in the footer. Looking at the current screenshot, I can see the page number is visible but may not have been properly selected when the alignment was attempted. I need to ensure the page number is selected first before applying alignment.
  
  #### 情况分析与思考过程
  
  The alignment didn't work because the page number wasn't properly selected. I need to:
  1. First, click directly on the page number "3" in the footer to select it (ensure it's highlighted)
  2. Then apply left alignment using either the left alignment button or Ctrl+L keyboard shortcut
  
  Looking at the footer area, I can see the page number "3". I'll click on it to select it first, then use the keyboard shortcut Ctrl+L to align it to the left, which is more reliable than trying to click the toolbar button.
  ```
- 操作:
  1. 左键单击坐标 (0.338, 0.736)
  2. 按下键盘按键: ctrl, l

### 步骤 14:
- 描述:
  ```
  #### 重要信息
  
  The page number "3" is visible in the footer but still appears to be centered rather than left-aligned. The previous Ctrl+L keyboard shortcut attempt didn't seem to work. I can see the footer is active (indicated by "Footer" in the paragraph style dropdown on the left). The page number needs to be selected first before alignment can be applied.
  
  #### 情况分析与思考过程
  
  The alignment attempts haven't worked because the page number field may not be properly selected. I need to:
  1. Triple-click on the page number "3" in the footer to select it completely (triple-click ensures the field is fully selected)
  2. Then apply left alignment using the left alignment button in the toolbar or try Ctrl+L again
  
  Looking at the footer area, I can see the page number "3" positioned in the center-bottom area. I'll triple-click on it to ensure it's fully selected, then apply left alignment.
  ```
- 操作:
  1. 左键三击坐标 (0.338, 0.736)
  2. 左键单击坐标 (0.555, 0.134)
