Step 2007

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 want to work out the maturity date for all the loans. Please do it for me in a new column with header "Maturity Date".。
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。

<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: Add 'Maturity Date' header in column C
  1.1: Click on cell C1 to select it
  1.2: Type 'Maturity Date' as the header
2: Create maturity date formula in C2
  2.1: Click on cell C2 to select it
  2.2: Enter formula =A2+B2 to calculate Issue Date + Days
  2.3: Press Enter to confirm the formula
3: Copy formula to all loan rows (C3 to C10)
  3.1: Select range C2:C10
  3.2: Use Ctrl+D to fill down the formula
4: Verify maturity dates are calculated correctly

## 2. 任务失败条件检查
- LibreOffice Calc is not running or has crashed
- The spreadsheet file is read-only or locked
- Column C already contains critical data that would be overwritten
- The loan data is not in the expected columns A and B

## 3. 关键视觉证据
- Cell C1 contains the header text 'Maturity Date'
- Cells C2 through C10 all contain calculated date values
- Cell C2 displays the date '14/01/2011' (calculated from 16/09/2010 + 120 days)

## 4. 上一次返回的决策

### 4.1. 上一次的观察和思考
```
#### 重要信息

- Cell C2 is currently selected (shown in cell reference box as "C2")
- Cell C2 displays "14/01/2011" which is the correctly calculated maturity date (16/09/2010 + 120 days)
- The formula bar shows "=A2+B2" confirming the formula is in place
- The data spans rows 2-10 (9 loans total)
- I need to copy the formula from C2 down to C3:C10

#### 情况分析与思考过程

The formula in C2 is working correctly. Now I need to:
1. Select the range C2:C10 (including the cell with the existing formula and all target cells)
2. Use Ctrl+D to fill down the formula to all rows

Since C2 is already selected, I'll drag from C2 to C10 to select the entire range, then use Ctrl+D to fill down the formula.
```



### 4.2. 上一次返回的操作
{"function": {"name": "computer", "arguments": {"actions": [{"action": "left_click_drag", "from_coordinate": [0.263, 0.303], "to_coordinate": [0.263, 0.431]}]}}}

## 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 Calc is open with a spreadsheet "MaturityDate.xlsx"
  - Column A contains "Loan Issue Date" with dates (16/09/2010, 09/12/2010, etc.)
  - Column B contains "Length of Loan in Days" with values (120, 90, 90, 100, etc.)
  - Column C is currently empty - this is where I need to add the "Maturity Date" column
  - Data spans rows 2-10 (9 loans total)
  - Cell B14 is currently selected
  
  #### 情况分析与思考过程
  
  The task is to calculate maturity dates by adding the Issue Date (Column A) + Length of Loan in Days (Column B), and put the results in a new Column C with header "Maturity Date".
  
  Following the strategy tree plan:
  1. First, I need to click on cell C1 to add the header "Maturity Date"
  2. Then create the formula in C2 (=A2+B2)
  3. Copy the formula down to C10
  4. Verify the results
  
  Let me start by clicking on cell C1 to select it and add the header.
- 操作:
  1. 左键单击坐标 (0.26, 0.287)

### 步骤 2:
- 描述:
  ```
  #### 重要信息
  
  - Cell C1 is now selected (shown in cell reference box and highlighted with orange border)
  - The formula bar is empty, ready for input
  - Cell C1 is positioned in column C, row 1, which is where the header needs to be added
  
  #### 情况分析与思考过程
  
  The previous action successfully selected cell C1. Now I need to type "Maturity Date" as the header text. This follows the strategy tree plan:
  1. ✓ Click on cell C1 (completed)
  2. → Type 'Maturity Date' (current step)
  3. Then move to C2 to create the formula
  4. Copy formula down to C10
  
  Since the cell is already selected and ready for input, I should type the header text "Maturity Date" now.
  ```
- 操作:
  1. 输入文本: Maturity Date

### 步骤 3:
- 描述:
  ```
  #### 重要信息
  
  - The header "Maturity Date" has been successfully entered in cell C1
  - The formula bar shows "Maturity Date" confirming the text was entered
  - Cell C1 is still selected with an orange border
  - Column A has dates (Loan Issue Date) and Column B has days (Length of Loan in Days)
  - I need to move to cell C2 to create the formula that adds A2+B2
  
  #### 情况分析与思考过程
  
  The header has been successfully added to C1. Now I need to:
  1. Move to cell C2 (either by pressing Enter or clicking on C2)
  2. Enter the formula =A2+B2 to calculate the maturity date
  3. Then copy this formula down to all rows with data (rows 2-10)
  
  Pressing Enter is the most efficient way to move from C1 to C2, as it will confirm the current entry and automatically move the cursor to the next cell down.
  ```
  
  
- 操作:
  1. 按下键盘按键: enter

### 步骤 4:
- 描述:
  ```
  #### 重要信息
  
  - Cell C2 is now selected (shown in cell reference box as "C2")
  - The formula bar is empty, ready for input
  - Cell C2 is highlighted with an orange border
  - Column A has dates (Loan Issue Date) and Column B has days (Length of Loan in Days)
  - I need to enter the formula =A2+B2 to calculate the maturity date
  
  #### 情况分析与思考过程
  
  The cursor has successfully moved to cell C2. Now I need to:
  1. Enter the formula =A2+B2 to calculate the maturity date (Issue Date + Days)
  2. Press Enter to confirm the formula
  3. Then copy the formula down to all rows with data (C3 to C10)
  
  This is a straightforward step - I'll type the formula =A2+B2 which will add the date in A2 to the number of days in B2.
  ```
- 操作:
  1. 输入文本: =A2+B2

### 步骤 5:
- 描述:
  ```
  #### 重要信息
  
  - Cell C2 is selected and shows the formula "=A2+B2" in both the cell and the formula bar
  - The formula has been entered but not yet confirmed (still showing formula text, not the calculated result)
  - Column A contains dates (Loan Issue Date) and Column B contains days (Length of Loan in Days)
  - I need to press Enter to confirm the formula, then copy it down to all rows (C3 to C10)
  
  #### 情况分析与思考过程
  
  The formula =A2+B2 has been typed into cell C2 but needs to be confirmed. Once I press Enter:
  1. The formula will be calculated and should show "14/01/2011" (16/09/2010 + 120 days)
  2. The cursor will move to C3
  3. Then I'll need to go back to C2 and copy the formula down to C10
  
  I'll press Enter to confirm the formula first.
  ```
  
  
- 操作:
  1. 按下键盘按键: enter

### 步骤 6:
- 描述:
  ```
  #### 重要信息
  
  - Cell C3 is currently selected (shown in cell reference box as "C3")
  - Cell C2 now displays "14/01/2011" which is the calculated maturity date (16/09/2010 + 120 days)
  - The formula in C2 has been confirmed and is working correctly
  - I need to copy this formula down to all remaining rows (C3 to C10)
  - The data spans rows 2-10 (9 loans total)
  
  #### 情况分析与思考过程
  
  The formula has been successfully created in C2 and shows the correct result. Now I need to:
  1. Select cell C2 first (since I'm currently in C3)
  2. Then select the range C2:C10 (to include the existing formula cell and all target cells)
  3. Use Ctrl+D to fill down the formula to all rows
  
  I'll start by clicking on C2 to select it, then I'll select the range C2:C10 and use Ctrl+D to copy the formula down.
  ```
- 操作:
  1. 左键单击坐标 (0.263, 0.303)
