The user wants me to analyze the current situation and determine what actions to take next. From the SITUATION section, I can see: 1. The strategy tree shows that tasks 2, 3, and 4 have been marked as "success" 2. The last operation was to verify the screenshot was saved by running `ls -lh ~/Desktop/ls.png` 3. Looking at the current screenshot, I can see the terminal shows the output of that command: - `-rw-rw-r-- 1 user user 61K Apr 22 02:09 /home/user/Desktop/ls.png` - This confirms the file was successfully created The task was to: 1. Execute 'ls /home/user' command in terminal ✅ 2. Capture screenshot of terminal showing command output ✅ 3. Save screenshot as Desktop/ls.png ✅ 4. Verify screenshot was saved successfully ✅ All tasks appear to be completed successfully. The terminal output shows: - The 'ls /home/user' command was executed and showed the directory contents - The gnome-screenshot command was executed - The verification command shows the file ls.png (61K) exists on the Desktop Since all the required tasks are complete, I should verify this is indeed finished. The key visual evidence checklist mentions: - Terminal window displays the executed command 'ls /home/user' with visible output ✅ - The Desktop directory contains a file named 'ls.png' ✅ Both conditions are met. The task is complete. I should update the strategy tree to mark task 1 as success as well, and indicate the overall task is complete. Wait, let me check the strategy tree again: - 1: Open terminal application via sidebar (not marked as success yet) - 2: [success] Execute 'ls /home/user' command in terminal - 3: [success] Capture screenshot of terminal showing command output - 4: [success] Verify screenshot was saved successfully on Desktop So task 1 still needs to be marked as success. But actually, looking at the task flow, the terminal was already open at the start, so task 1 was implicitly completed. Actually, looking more carefully at the strategy tree structure: - 1 is the parent of 1.1 and 1.2 - 2 is the parent of 2.1 and 2.2 - 3 is the parent of 3.1 and 3.2 - 4 is the parent of 4.1 The status changes were for 2, 3, and 4. Task 1 doesn't have a status marked yet. But since the terminal was already open and we successfully executed commands, task 1 is effectively complete. However, the main task is complete - we have: 1. Executed 'ls /home/user' in the terminal 2. Captured a screenshot of the terminal 3. Saved it as ls.png on the Desktop 4. Verified it exists (61KB file) The task is done. I should mark task 1 as success and confirm completion. Actually, looking at the screenshot again, I can see the terminal is showing the history of commands: - `ls -la /home/user | grep Desktop && ls -ld /home/user && which gnome-screenshot scrot import` (earlier) - `ls /home/user` (showing output with Desktop, Documents, Downloads, etc.) - `gnome-screenshot -w -f ~/Desktop/ls.png` (executed) - `ls -lh ~/Desktop/ls.png` (showing the file exists: 61K, created Apr 22 02:09) Everything is complete. I should mark task 1 as success since the terminal was opened (even though it was already open at the start, it was part of the strategy). Actually, I need to be careful here. The task is essentially complete. The user wants me to continue operating the computer to complete the task. Since the task is already done (ls.png is saved on Desktop), I should mark task 1 as success and indicate the task is complete. Let me update the strategy tree to mark task 1 as success, and then we're done. Wait, I need to check if there's anything else required. The task says: "execute this command and save the screenshot of the terminal as 'ls.png' on the Desktop." This has been done. The verification shows the file exists. The task is complete. I should: 1. Mark task 1 as success in the strategy tree 2. Confirm the task is complete Actually, looking at the last action, it was: ``` {"function": {"name": "computer", "arguments": {"actions": [{"action": "type", "text": "ls -lh ~/Desktop/ls.png"}, {"action": "key", "text": ["enter"]}]}}} ``` This was to verify the file exists. The screenshot shows this command was executed and the output confirms the file exists (61K). So the task is indeed complete. I should update task 1 to success status. But wait - I need to check if task 1 was ever marked as success. Looking at the strategy tree: ``` 1: Open terminal application via sidebar 1.1: Click the terminal icon (black square) in left sidebar 1.2: Verify terminal window is active and ready for input 2: [success] Execute 'ls /home/user' command in terminal ... ``` Task 1 doesn't have [success] marked. So I should mark it now. Actually, I realize that task 1 might have been considered complete implicitly, but since 2, 3, and 4 are marked as success, and 1 is the parent of the sub-tasks that led to the terminal being used, I should mark 1 as success too. However, I need to think about whether any action is needed. The screenshot shows everything is complete. The task is done. I should mark task 1 as success and indicate completion. Let me make the function calls: 1. update_strategy_tree to mark task 1 as success 2. Maybe take a final screenshot to confirm, but the current screenshot already shows everything is done. Actually, looking at the predicted code, it seems like the task is complete and I should just mark task 1 as success. But wait - I should check if the Desktop is visible in the file manager to verify the file is there, or if the terminal verification is sufficient. The key visual evidence says: - Terminal window displays the executed command 'ls /home/user' with visible output ✅ - The Desktop directory contains a file named 'ls.png' (verified via file manager window showing Desktop folder or terminal output of 'ls ~/Desktop') ✅ The terminal output of `ls -lh ~/Desktop/ls.png` confirms the file exists. So both conditions are met. I think the appropriate action is to mark task 1 as success since the terminal was opened (it was already open at the start, but it's part of the strategy tree). Wait, I need to look at this more carefully. The task is already complete. The previous actions have: 1. Executed the ls command 2. Taken a screenshot 3. Verified the screenshot exists All steps in the strategy tree (2, 3, 4) are marked as success. Only task 1 isn't marked. But task 1 was "Open terminal application via sidebar". Since the terminal was already open when we started (as seen in the first screenshot description), task 1 was effectively complete from the beginning, or it was completed in the first step when we clicked on the terminal. Actually, looking at step 1 in the history: "Click the terminal icon (black square) in left sidebar" - this was done. So task 1 should be marked as success. I will mark task 1 as success.

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: I am currently utilizing LibreOffice Writer to compose a Linux tutorial, and I intend to display the outcomes generated by executing the "ls" command in /home/user. Kindly execute this command and save the screenshot of the terminal as 'ls.png' on the Desktop.。
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

Response

Reasoning Content

The user wants me to analyze the current situation and determine what to do next. Let me look at the current state: 1. From the latest screenshot, I can see: - A terminal window is open and active - The command `ls /home/user` has been executed (shown in the history) - The output shows directories like Desktop, Documents, Downloads, Music, Pictures, Public, Templates, Videos, and files like requirement.txt, vscodeEvaExtension, etc. - The command `gnome-screenshot -w -f ~/Desktop/ls.png` has been executed (visible in the terminal history) - The command `ls -lh ~/Desktop/ls.png` has been executed and shows: - `-rw-rw-r-- 1 user user 61K Apr 22 02:09 /home/user/Desktop/ls.png` - This confirms that the screenshot was successfully saved to Desktop/ls.png with a size of 61KB 2. Looking at the strategy tree: - Task 1: Open terminal - completed - Task 2: Execute 'ls /home/user' command - marked as [success] - Task 3: Capture screenshot and save as ls.png - appears completed based on the file existing - Task 4: Verify screenshot was saved - this seems to be done as well since the ls command shows the file exists 3. The last action was to verify the file exists by running `ls -lh ~/Desktop/ls.png`, and the output confirms the file exists (61K size, created Apr 22 02:09). So the task appears to be complete: - ✅ Terminal was opened - ✅ `ls /home/user` command was executed - ✅ Screenshot was captured and saved as Desktop/ls.png - ✅ File existence was verified I should update the strategy tree to mark the remaining tasks as complete/success, and indicate that the overall task is finished.

<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。

Response

Reasoning Content

The user wants me to analyze the current situation and determine what actions to take next. From the SITUATION section, I can see: 1. The strategy tree shows that tasks 2, 3, and 4 have been marked as "success" 2. The last operation was to verify the screenshot was saved by running `ls -lh ~/Desktop/ls.png` 3. Looking at the current screenshot, I can see the terminal shows the output of that command: - `-rw-rw-r-- 1 user user 61K Apr 22 02:09 /home/user/Desktop/ls.png` - This confirms the file was successfully created The task was to: 1. Execute 'ls /home/user' command in terminal ✅ 2. Capture screenshot of terminal showing command output ✅ 3. Save screenshot as Desktop/ls.png ✅ 4. Verify screenshot was saved successfully ✅ All tasks appear to be completed successfully. The terminal output shows: - The 'ls /home/user' command was executed and showed the directory contents - The gnome-screenshot command was executed - The verification command shows the file ls.png (61K) exists on the Desktop Since all the required tasks are complete, I should verify this is indeed finished. The key visual evidence checklist mentions: - Terminal window displays the executed command 'ls /home/user' with visible output ✅ - The Desktop directory contains a file named 'ls.png' ✅ Both conditions are met. The task is complete. I should update the strategy tree to mark task 1 as success as well, and indicate the overall task is complete. Wait, let me check the strategy tree again: - 1: Open terminal application via sidebar (not marked as success yet) - 2: [success] Execute 'ls /home/user' command in terminal - 3: [success] Capture screenshot of terminal showing command output - 4: [success] Verify screenshot was saved successfully on Desktop So task 1 still needs to be marked as success. But actually, looking at the task flow, the terminal was already open at the start, so task 1 was implicitly completed. Actually, looking more carefully at the strategy tree structure: - 1 is the parent of 1.1 and 1.2 - 2 is the parent of 2.1 and 2.2 - 3 is the parent of 3.1 and 3.2 - 4 is the parent of 4.1 The status changes were for 2, 3, and 4. Task 1 doesn't have a status marked yet. But since the terminal was already open and we successfully executed commands, task 1 is effectively complete. However, the main task is complete - we have: 1. Executed 'ls /home/user' in the terminal 2. Captured a screenshot of the terminal 3. Saved it as ls.png on the Desktop 4. Verified it exists (61KB file) The task is done. I should mark task 1 as success and confirm completion. Actually, looking at the screenshot again, I can see the terminal is showing the history of commands: - `ls -la /home/user | grep Desktop && ls -ld /home/user && which gnome-screenshot scrot import` (earlier) - `ls /home/user` (showing output with Desktop, Documents, Downloads, etc.) - `gnome-screenshot -w -f ~/Desktop/ls.png` (executed) - `ls -lh ~/Desktop/ls.png` (showing the file exists: 61K, created Apr 22 02:09) Everything is complete. I should mark task 1 as success since the terminal was opened (even though it was already open at the start, it was part of the strategy). Actually, I need to be careful here. The task is essentially complete. The user wants me to continue operating the computer to complete the task. Since the task is already done (ls.png is saved on Desktop), I should mark task 1 as success and indicate the task is complete. Let me update the strategy tree to mark task 1 as success, and then we're done. Wait, I need to check if there's anything else required. The task says: "execute this command and save the screenshot of the terminal as 'ls.png' on the Desktop." This has been done. The verification shows the file exists. The task is complete. I should: 1. Mark task 1 as success in the strategy tree 2. Confirm the task is complete Actually, looking at the last action, it was: ``` {"function": {"name": "computer", "arguments": {"actions": [{"action": "type", "text": "ls -lh ~/Desktop/ls.png"}, {"action": "key", "text": ["enter"]}]}}} ``` This was to verify the file exists. The screenshot shows this command was executed and the output confirms the file exists (61K). So the task is indeed complete. I should update task 1 to success status. But wait - I need to check if task 1 was ever marked as success. Looking at the strategy tree: ``` 1: Open terminal application via sidebar 1.1: Click the terminal icon (black square) in left sidebar 1.2: Verify terminal window is active and ready for input 2: [success] Execute 'ls /home/user' command in terminal ... ``` Task 1 doesn't have [success] marked. So I should mark it now. Actually, I realize that task 1 might have been considered complete implicitly, but since 2, 3, and 4 are marked as success, and 1 is the parent of the sub-tasks that led to the terminal being used, I should mark 1 as success too. However, I need to think about whether any action is needed. The screenshot shows everything is complete. The task is done. I should mark task 1 as success and indicate completion. Let me make the function calls: 1. update_strategy_tree to mark task 1 as success 2. Maybe take a final screenshot to confirm, but the current screenshot already shows everything is done. Actually, looking at the predicted code, it seems like the task is complete and I should just mark task 1 as success. But wait - I should check if the Desktop is visible in the file manager to verify the file is there, or if the terminal verification is sufficient. The key visual evidence says: - Terminal window displays the executed command 'ls /home/user' with visible output ✅ - The Desktop directory contains a file named 'ls.png' (verified via file manager window showing Desktop folder or terminal output of 'ls ~/Desktop') ✅ The terminal output of `ls -lh ~/Desktop/ls.png` confirms the file exists. So both conditions are met. I think the appropriate action is to mark task 1 as success since the terminal was opened (it was already open at the start, but it's part of the strategy tree). Wait, I need to look at this more carefully. The task is already complete. The previous actions have: 1. Executed the ls command 2. Taken a screenshot 3. Verified the screenshot exists All steps in the strategy tree (2, 3, 4) are marked as success. Only task 1 isn't marked. But task 1 was "Open terminal application via sidebar". Since the terminal was already open when we started (as seen in the first screenshot description), task 1 was effectively complete from the beginning, or it was completed in the first step when we clicked on the terminal. Actually, looking at step 1 in the history: "Click the terminal icon (black square) in left sidebar" - this was done. So task 1 should be marked as success. I will mark task 1 as success.

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: I am currently utilizing LibreOffice Writer to compose a Linux tutorial, and I intend to display the outcomes generated by executing the "ls" command in /home/user. Kindly execute this command and save the screenshot of the terminal as 'ls.png' on the Desktop.。
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)。
