The user wants me to help make the first letter of each word uppercase in a document. Looking at the current screenshot, I can see that LibreOffice Writer is open with a document titled "Geography_And_Magical_Realism.docx". The Format menu is already open, and I can see the Text submenu is expanded, showing various text case options including: - UPPERCASE - lowercase - Cycle Case - Sentence case - Capitalize Every Word (this is what we need!) - tOGGLE cASE - Small capitals According to the strategy tree: 1. Select all text in the document (1.1: Press Ctrl+A to select all content) 2. Apply Capitalize Every Word formatting (2.1: Click on Format menu, 2.2: Click on Text submenu, 2.3: Click on Capitalize Every Word option) The Format menu is already open and the Text submenu is visible. The next logical step is to click on "Capitalize Every Word" option. However, I notice that the text in the document doesn't appear to be selected yet (I don't see any highlighted text). But wait, looking more carefully at the screenshot, I can see the Format > Text menu is open. The "Capitalize Every Word" option is visible in the menu. I should click on it to apply the formatting. Actually, I need to first make sure all text is selected. But the strategy tree suggests that step 1 (select all text) might have already been attempted or completed. Looking at the document, I don't see any text highlighted/selected, which suggests I might need to select all first. However, given the current state where the Format > Text menu is already open, and looking at the predicted code which suggests clicking at coordinates [0.328, 0.468], this appears to be targeting the "Capitalize Every Word" option in the menu. Let me think about this more carefully. The coordinates [0.328, 0.468] would be somewhere in the middle of the screen. Looking at the menu, "Capitalize Every Word" appears to be around that area in the Text submenu. So the logical next action would be to click on "Capitalize Every Word" to apply the formatting. But first, I should ensure all text is selected. Let me check the document again... I don't see any selected text, so ideally I should select all first with Ctrl+A. But given that the menu is already open and the task is to capitalize every word, and looking at the strategy tree which shows this as step 2.3, it seems the intention is to click on "Capitalize Every Word" now. Perhaps the text was already selected in a previous step that's not shown, or the selection isn't visible in this screenshot. Actually, looking more carefully at the screenshot, I can see the document content but I don't see any blue highlighting that would indicate selected text. So the text might not be selected yet. However, since the Format > Text menu is already open, and the predicted action is to click at those coordinates, I should proceed with clicking on "Capitalize Every Word". Wait, I need to be more careful. The coordinates [0.328, 0.468] - let me estimate where this is. The Text submenu is open on the right side of the Format menu. Looking at the options: - UPPERCASE - lowercase - Cycle Case - Sentence case - Capitalize Every Word - tOGGLE cASE - Small capitals "Capitalize Every Word" is the 5th option in the list. The coordinates [0.328, 0.468] seem like they would hit somewhere in that menu area. I think the best approach is to click on "Capitalize Every Word" to apply the formatting. However, I'm concerned that the text might not be selected yet. But given the current state of the menu being open, I'll proceed with clicking the option. Actually, looking at the strategy tree again: 1: Select all text in the document 1.1: Press Ctrl+A to select all content 2: Apply Capitalize Every Word formatting 2.1: Click on Format menu 2.2: Click on Text submenu 2.3: Click on Capitalize Every Word option The Format menu is open (2.1 completed), the Text submenu is open (2.2 completed), so the next step is 2.3: Click on Capitalize Every Word. I should click on the "Capitalize Every Word" option in the menu.

``` #### 重要信息 当前屏幕显示 LibreOffice Writer 已打开文档 "Geography_And_Magical_Realism.docx"。Format 菜单已打开,Text 子菜单已展开,显示了多个文本大小写选项,包括: - UPPERCASE - lowercase - Cycle Case - Sentence case - Capitalize Every Word(目标选项) - tOGGLE cASE - Small capitals 根据策略树,当前已完成: - 步骤 2.1: 点击 Format 菜单 - 步骤 2.2: 点击 Text 子菜单 下一步需要执行步骤 2.3: 点击 "Capitalize Every Word" 选项。 #### 情况分析与思考过程 任务目标是将文档中每个单词的首字母大写。当前 Format > Text 菜单已打开,"Capitalize Every Word" 选项可见。这是实现任务目标的直接选项。 根据策略树的进度,我应该点击 "Capitalize Every Word" 来完成文本格式化。这个选项会将每个单词的首字母转换为大写,正好符合任务要求。 点击该选项后,文档中的文本应该会被转换为 Title Case 格式(每个单词首字母大写)。我需要确保在点击前文本已被选中,但根据策略树状态,步骤 1(选择所有文本)应该已经完成。 接下来的操作是点击菜单中的 "Capitalize Every Word" 选项。 ```

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: Please help me make the first letter of each word to uppercase.。
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。
