The previous action successfully navigated to slide 3. I can now see slide 3 is displayed in the main editing area, showing a blonde woman's photo. The slide has a purple/blue background (#E6D8F4) that needs to be changed to yellow. Looking at the Properties panel on the right side, I can see: - Format: User - Orientation: Landscape - Background: Color with value #E6D8F4 (purple) To change the background color to yellow, I need to click on the color dropdown or the color selector in the Properties panel. I can see there's a dropdown next to the color value #E6D8F4. Let me click on that to open the color picker and select yellow. My plan is: 1. Click on the color dropdown in the Properties panel to open color options 2. Select yellow color 3. Then navigate to slide 4 and repeat the process 4. Save the presentation Let me click on the color dropdown button next to #E6D8F4 in the Properties panel.

``` #### 重要信息 - Successfully navigated to slide 3 which shows the blonde woman photo - The slide currently has a purple/blue background (#E6D8F4) - The Properties panel on the right shows Background is set to "Color" - There's a color selector showing #E6D8F4 with a dropdown button next to it - Need to change this background color to yellow #### 情况分析与思考过程 I'm now on slide 3 which contains the photo of a real person (blonde woman). The current background is purple (#E6D8F4) and needs to be changed to yellow. Looking at the Properties panel on the right: - Background is already set to "Color" - The current color is #E6D8F4 - There's a dropdown button next to the color value I need to click on the color dropdown to open the color picker and select yellow. After that, I'll navigate to slide 4 and do the same, then save the presentation. Let me click on the dropdown button next to the color value in the Properties panel. ```

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: Set the background color to yellow for any slide that contains one or more images of real people, and set the title of slide 2 as "Let's start".。
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

...

#### 情况分析与思考过程

...
```
</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

text (2726 chars)
## 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 presentation "13_0.pptx"
  - Currently viewing slide 3 of 6, which shows a blonde woman photo
  - The Properties panel on the right shows Background is set to "Color" with purple (#E6D8F4)
  - Slide 4 thumbnail shows three circular photos of people
  - Slide 2 thumbnail is visible in the left sidebar and needs its title changed to "Let's start"
  - The task requires: 1) Change slide 2 title to "Let's start", 2) Set yellow background for slides with real people photos (slides 3 and 4)
  
  #### 情况分析与思考过程
  I need to complete two main tasks:
  1. Change slide 2's title from "Introduction" to "Let's start"
  2. Set yellow background for slides 3 and 4 (both contain photos of real people)
  
  Looking at the current state, I'm on slide 3. I should start by navigating to slide 2 to change its title. I can see slide 2's thumbnail in the left sidebar. I'll click on it to navigate there first.
  ```
  
- 操作:
  1. 左键单击坐标 (0.088, 0.329)

### 步骤 2:
- 描述:
  ```
  #### 重要信息
  - Successfully navigated to slide 2
  - Slide 2 is now displayed with title "Introduction" visible in the center
  - The slide has a blue/purple background with fish illustrations
  - Need to change the title from "Introduction" to "Let's start"
  - After that, need to set yellow backgrounds for slides 3 and 4
  
  #### 情况分析与思考过程
  I'm now on slide 2 and can see the title "Introduction" that needs to be changed to "Let's start". To edit the title text:
  1. I need to click on the title text to select the text box
  2. Then select all the text and type the new title "Let's start"
  
  The title "Introduction" is visible in the center of the slide. I'll click on it to select the text box for editing.
  ```
- 操作:
  1. 左键单击坐标 (0.433, 0.556)

### 步骤 3:
- 描述:
  ```
  #### 重要信息
  - The text box containing "Introduction" is now selected and active for editing
  - The cursor is positioned in the text (status bar shows "TextEdit: Paragraph 1, Row 1, Column 7")
  - The text box has an orange border indicating it's selected
  - Need to select all text and replace it with "Let's start"
  
  #### 情况分析与思考过程
  The previous action successfully clicked on the title text box. Now I can see the cursor is in the text and the text box is active for editing. To change the title from "Introduction" to "Let's start":
  
  1. First, I need to select all the current text using Ctrl+A
  2. Then type "Let's start" to replace the selected text
  
  This is a simple text replacement operation. After this is done, I'll need to move on to changing the background colors for slides 3 and 4.
  ```
- 操作:
  1. 按下键盘按键: ctrl, a
  2. 输入文本: Let's start
