Step 2014

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: In the last slide, make the font style "Times New Roman"。
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）。

```
#### 重要信息

```
</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: [success] Navigate to the last slide (slide 5)
  1.1: Click on slide 5 thumbnail in the left panel
2: [success] Select text on the last slide
  2.1: Click on the text area to activate it
  2.2: Select all text (Ctrl+A) or specific text
3: [success] Change font to Times New Roman
  3.1: Open font dropdown in toolbar or Format menu
  3.2: Select 'Times New Roman' from font list

## 2. 任务失败条件检查
- LibreOffice Impress is not installed or not running
- The presentation file cannot be accessed or is corrupted
- There is no last slide (empty presentation)
- Times New Roman font is not available on the system
- The last slide has no editable text content

## 3. 关键视觉证据
- Slide 5 (the last slide) is selected in the left slides panel and the status bar shows 'Slide 5 of 5'
- The Properties panel on the right displays 'Times New Roman' in the Font field
- The text 'Conclusion' in slide 5 appears in Times New Roman font style

## 4. 上一次返回的决策

### 4.1. 上一次的观察和思考
```
#### 重要信息

- The font has been successfully changed to "Times New Roman" - the Properties panel on the right now shows "Times New Roman" in the Font field (highlighted in orange)
- The "Conclusion" text on slide 5 is still selected and now appears in Times New Roman font (serif style)
- Slide 5 is confirmed as the last slide (status bar shows "Slide 5 of 5")
- All key visual evidence requirements are met:
  - Slide 5 is selected
  - Properties panel shows Times New Roman
  - The text appears in Times New Roman font

#### 情况分析与思考过程

The task has been completed successfully! The font on the last slide has been changed to Times New Roman. The "Conclusion" text is now displaying in Times New Roman font as evidenced by the serif style and the Properties panel confirmation.

Now I should save the file to preserve these changes. I'll use Ctrl+S to save the presentation.
```

I will now save the file to preserve the changes and mark the strategy tree tasks as complete.

### 4.2. 上一次返回的操作
{"function": {"name": "computer", "arguments": {"actions": [{"action": "key", "text": ["ctrl", "s"]}]}}}

## 5. 屏幕截图

## 6. 上一次操作的前50步操作简述
### 步骤 1:
- 描述:
  ```
  #### 重要信息
  
  - LibreOffice Impress is open with a 5-slide presentation
  - Currently viewing Slide 1 "Introduction" (status bar shows "Slide 1 of 5")
  - The left panel shows all 5 slides, with slide 5 labeled "Conclusion" at the bottom
  - Slide 5 appears to be the last slide I need to work with
  - The task requires changing the font to "Times New Roman" on the last slide
  
  #### 情况分析与思考过程
  
  I need to complete the task of changing the font style to "Times New Roman" on the last slide. The strategy tree shows a clear plan:
  1. Navigate to slide 5 (the last slide)
  2. Select text on that slide
  3. Change the font to Times New Roman
  
  Currently, I'm on slide 1. The first step is to navigate to slide 5 by clicking on its thumbnail in the left panel. I can see slide 5 at the bottom of the slides panel on the left side - it shows "Conclusion" label.
  
  I'll click on slide 5's thumbnail to navigate to it.
  ```
- 操作:
  1. 左键单击坐标 (0.086, 0.706)

### 步骤 2:
- 描述:
  ```
  #### 重要信息
  
  - Successfully navigated to slide 5 (the last slide) - "Conclusion"
  - Status bar confirms "Slide 5 of 5"
  - Slide 5 is now highlighted in the left panel with an orange border
  - The slide contains a "Conclusion" heading text that needs font change
  - There's also a "Click to add Text" bullet point area
  
  #### 情况分析与思考过程
  
  The previous action was successful - I'm now on slide 5. According to the strategy tree, the next step is to select text on this slide. I need to:
  1. First, click on the "Conclusion" heading text to select it
  2. Then change its font to Times New Roman
  
  I'll click on the "Conclusion" text to activate/select it. This should allow me to then modify its font properties.
  ```
- 操作:
  1. 左键单击坐标 (0.433, 0.323)

### 步骤 3:
- 描述:
  ```
  #### 重要信息
  
  - The "Conclusion" text is now in edit mode (cursor visible in the text)
  - The Properties panel shows Character properties with current font "Calibri" at 44 pt
  - The text box is active and ready for text selection
  - Need to select all text and change font to Times New Roman
  
  #### 情况分析与思考过程
  
  The previous action successfully activated the text box. Now I can see the cursor in the "Conclusion" text. To change the font, I need to:
  1. First select all the text (Ctrl+A)
  2. Then change the font to Times New Roman using the font dropdown in the Properties panel
  
  I'll select all text first with Ctrl+A, which will highlight all the text in the current text box, making it ready for font change.
  ```
- 操作:
  1. 按下键盘按键: ctrl, a

### 步骤 4:
- 描述:
  ```
  #### 重要信息
  
  - The "Conclusion" text is now fully selected (highlighted in orange)
  - The Properties panel on the right shows the font dropdown with "Calibri" currently selected
  - The text is ready for font change - I just need to click on the font dropdown and select "Times New Roman"
  
  #### 情况分析与思考过程
  
  The Ctrl+A command successfully selected all the text in the text box. Now I can see "Conclusion" is highlighted. To change the font to Times New Roman, I need to:
  
  1. Click on the font dropdown in the Properties panel (currently showing "Calibri")
  2. Select "Times New Roman" from the dropdown list
  
  The font dropdown is visible in the Character section of the Properties panel on the right side of the screen. I'll click on it to open the font list.
  ```

  1. 左键单击坐标 (0.821, 0.219)

### 步骤 5:
- 描述:
  ```
  #### 重要信息
  
  - The "Conclusion" text is still selected (highlighted in orange)
  - The Properties panel shows the font field with "Calibri" selected
  - A "Font Name" tooltip is visible, indicating the font field area
  - The font dropdown menu has not opened yet from the previous click
  
  #### 情况分析与思考过程
  
  The previous click didn't successfully open the font dropdown. I need to click more precisely on the dropdown arrow button next to the "Calibri" font field. Looking at the Properties panel, the font dropdown arrow appears to be to the right of the font name field.
  
  Once I click on the dropdown arrow, a list of available fonts should appear, and I'll need to scroll down to find and select "Times New Roman". Let me click on the dropdown arrow button.
  ```
- 操作:
  1. 左键单击坐标 (0.9, 0.219)

### 步骤 6:
- 描述:
  ```
  #### 重要信息
  
  - The font dropdown menu is now open showing various font options
  - "Calibri" is currently highlighted in orange (the current font)
  - The list shows fonts alphabetically: Aakar, Abyssinica SIL, Alice, AnjaliOldLipi, Arial, Arial Black, Arial CE, Arial CE MT Black, Arial Light, Arial Narrow, C059, Calibri (selected), Cambria, Caveat, etc.
  - I need to scroll down to find "Times New Roman" which should be near the end alphabetically (starts with "T")
  
  #### 情况分析与思考过程
  
  The font dropdown successfully opened. Now I need to scroll down through the alphabetical list to find "Times New Roman". Since the list is alphabetical and currently showing fonts starting with A-C, I need to scroll down quite a bit to reach fonts starting with "T".
  
  I'll scroll down in the dropdown list to locate "Times New Roman".
  ```

  - "Noto Sans Medium" is currently highlighted in orange
  - I need to continue scrolling down to reach fonts starting with "T" for "Times New Roman"
  
  #### 情况分析与思考过程
  
  The previous scroll moved the list from M to N. Since I need to find "Times New Roman" which starts with "T", and the list is alphabetical, I need to continue scrolling down. The current view shows many "Noto Sans" font variants starting with N, so I need to scroll past O, P, Q, R, S to reach T.
  
  I'll continue scrolling down in the font dropdown to locate "Times New Roman".
  ```

  - "Roboto Condensed Light" is currently highlighted in orange
  - I need to continue scrolling down to reach fonts starting with "T" for "Times New Roman" - I'm very close now, just need to scroll past S to reach T
  
  #### 情况分析与思考过程
  
  The previous scroll moved the list from N to R. Since I need to find "Times New Roman" which starts with "T", and the list is alphabetical, I need to continue scrolling down just a bit more. The current view shows fonts starting with R (Roboto variants), so I just need to scroll past S to reach T where "Times New Roman" should be located.
  
  I'll continue scrolling down in the font dropdown to locate "Times New Roman". I'm very close now.

  - The font dropdown menu is still open showing font options
  - The list has scrolled to show fonts starting with T, and I can now see "Times", "Times New Roman", and "Times New Roman Cyr" at the bottom of the visible area
  - The "Conclusion" text on slide 5 is still selected (highlighted in orange)
  - I've successfully located "Times New Roman" in the font list
  
  #### 情况分析与思考过程
  
  Excellent! The previous scroll successfully brought "Times New Roman" into view. I can now see it in the font dropdown list along with "Times" and "Times New Roman Cyr" just below it.
  
  Now I need to click on "Times New Roman" to select it and apply this font to the currently selected "Conclusion" text. This will complete the task of changing the font style on the last slide to Times New Roman.
  
  After clicking on "Times New Roman", the font should be applied to the selected text, and I should see the "Conclusion" text change from its current font to Times New Roman.
  ```
