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: According to the scale table shown above, calculate and give each student a grade in the table below. Finish the work and don't touch irrelevant regions, even if they are blank.。
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）。

</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: Analyze the grading scale from the reference table (rows 2-7)
  1.1: Identify grade boundaries: 0-29=Fail, 30-59=Pass, 60-79=Average, 80-89=Above average, 90-99=Excellent, 100=Exceptional
2: Calculate and enter grades in the Message column (F) for each student
  2.1: Click on cell F10 (first student Benedict) and enter grade based on mark 42
  2.2: Continue entering grades for remaining students (rows 11-23) based on their marks
3: Verify all grades are correctly assigned and save the file
  3.1: Cross-check a few entries against the scale table to ensure accuracy
  3.2: Save the spreadsheet (Ctrl+S)

## 2. 任务失败条件检查
- LibreOffice Calc is not installed or not running
- The spreadsheet file is read-only or locked
- The scale table data is missing or corrupted
- Student data table is empty or inaccessible

## 3. 关键视觉证据
- Cell F10 (Benedict's grade) displays 'Pass'
- Cell F13 (Arnold's grade) displays 'Fail'
- Cell F15 (Olivia's grade) displays 'Average'
- Cell F20 (John's grade) displays 'Above average'
- Cell F11 (Blake's grade) displays 'Excellent'
- Cell F22 (Swan's grade) displays 'Exceptional'

## 4. 上一次返回的决策

### 4.1. 上一次的观察和思考
```
#### 重要信息

- LibreOffice Calc is open with student grades spreadsheet
- Cell F17 now shows "Average" for Elijah (mark 60) - correct!
- The formula bar confirms "Average" is entered
- Current position: F17 (done)
- Next: F18 - Tom with mark 10 → should be "Fail"

#### 情况分析与思考过程

Good progress! Eight grades are now correctly entered:
- F10: Pass (Benedict, 42) ✓
- F11: Excellent (Blake, 94) ✓
- F12: Pass (Bey, 33) ✓
- F13: Fail (Arnold, 6) ✓
- F14: Above average (Clint, 86) ✓
- F15: Average (Olivia, 67) ✓
- F16: Pass (Parah, 59) ✓
- F17: Average (Elijah, 60) ✓

Now I need to continue with the remaining students. I'll move to F18 and enter the grades systematically.

Remaining students:
- F18: Tom (10) → Fail
- F19: John (85) → Above average
- F20: Kanee (5) → Fail
- F21: Reese (73) → Average
- F22: Swan (100) → Exceptional
- F23: 50 Dollar (32) → Pass

I'll press Down to move to F18 and continue entering grades. I can batch the remaining entries since they're straightforward.
```

### 4.2. 上一次返回的操作
{"function": {"name": "computer", "arguments": {"actions": [{"action": "key", "text": ["down"]}, {"action": "key", "text": ["delete"]}, {"action": "type", "text": "Fail"}, {"action": "key", "text": ["down"]}, {"action": "key", "text": ["delete"]}, {"action": "type", "text": "Above average"}, {"action": "key", "text": ["down"]}, {"action": "key", "text": ["delete"]}, {"action": "type", "text": "Fail"}, {"action": "key", "text": ["down"]}, {"action": "key", "text": ["delete"]}, {"action": "type", "text": "Average"}, {"action": "key", "text": ["down"]}, {"action": "key", "text": ["delete"]}, {"action": "type", "text": "Exceptional"}, {"action": "key", "text": ["down"]}, {"action": "key", "text": ["delete"]}, {"action": "type", "text": "Pass"}]}}}

## 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 containing student grades
  - The scale table is visible in rows 2-7 showing grade boundaries
  - Student data is in rows 10-23 with names in column C, marks in column D
  - The Message column (F) is where grades need to be entered
  - Cell F10 is already selected (Benedict's row with mark 42)
  - Benedict's mark 42 falls in the Pass range (30-59)
  
  #### 情况分析与思考过程
  
  The task is to calculate and enter grades for each student based on the scale table. I can see:
  - Scale: 0=Fail, 30=Pass, 60=Average, 80=Above average, 90=Excellent, 100=Exceptional
  
  Students and their calculated grades:
  - Benedict (42): Pass
  - Blake (94): Excellent
  - Bey (33): Pass
  - Arnold (6): Fail
  - Clint (86): Above average
  - Olivia (67): Average
  - Parah (59): Pass
  - Elijah (60): Average
  - Tom (10): Fail
  - John (85): Above average
  - Kanee (5): Fail
  - Reese (73): Average
  - Swan (100): Exceptional
  - 50 Dollar (32): Pass
  
  Since F10 is already selected, I'll start entering the grades. I'll type "Pass" for Benedict, then move to the next cells to continue entering all grades.</think>

### 步骤 2:
- 描述:
  ```
  #### 重要信息
  
  - LibreOffice Calc is open with student grades spreadsheet
  - The Message column (F) shows grades have been entered but many appear incorrect or merged with other text
  - Current cell is F22 (Swan's row)
  - The formula bar shows "Pass" for the current cell
  - Multiple grades seem to have been entered incorrectly - they appear to be merged with marks or other text
  - Need to correct all grades in column F (rows 10-23)
  
  #### 情况分析与思考过程
  
  The previous batch action attempted to enter all grades at once, but it appears the entries got corrupted or merged. Looking at the visible data:
  - Row 10: Shows "42Pass" instead of just "Pass"
  - Row 11: Shows "94ExcellentPass" instead of just "Excellent"
  - Row 12: Shows "33Fail" instead of "Pass"
  - And so on...
  
  I need to fix these entries. The best approach is to:
  1. Click on each cell in column F
  2. Clear the incorrect content
  3. Enter the correct grade
  
  Let me start by clicking on F10 (Benedict's grade cell) and clearing it, then entering the correct grade. I'll work through each student systematically.
  
  The scale is:
  - 0-29: Fail
  - 30-59: Pass
  - 60-79: Average
  - 80-89: Above average
  - 90-99: Excellent
  - 100: Exceptional
  
  Students and correct grades:
  - Benedict (42): Pass
  - Blake (94): Excellent
  - Bey (33): Pass
  - Arnold (6): Fail
  - Clint (86): Above average
  - Olivia (67): Average
  - Parah (59): Pass
  - Elijah (60): Average
  - Tom (10): Fail
  - John (85): Above average
  - Kanee (5): Fail
  - Reese (73): Average
  - Swan (100): Exceptional
  - 50 Dollar (32): Pass
  
  I'll start by clicking on F10 and fixing the grades one by one.
  ```
- 操作:
  1. 左键单击坐标 (0.281, 0.423)
  2. 按下键盘按键: delete
  3. 输入文本: Pass

### 步骤 3:

  #### 重要信息
  
  - LibreOffice Calc is open with student grades spreadsheet
  - The cell reference shows F9 and formula bar shows "Pass"
  - The Message column (F) shows corrupted data like "42 Pass", "94 ExcellentPass", "33 Fail"
  - The grades need to be corrected based on the scale table
  - Current view shows the student data table with names, marks, and the Message column
  
  #### 情况分析与思考过程
  
  The previous action didn't properly fix the cell. Looking at the current state:
  - The grades in column F are corrupted/mixed with marks
  - I need to systematically fix each cell by clicking on it, clearing it, and entering the correct grade
  
  Let me start fresh by clicking on F10 (Benedict's row) and fixing it properly. Then I'll continue with the other cells one by one.
  
  The correct grades should be:
  - Benedict (42): Pass
  - Blake (94): Excellent
  - Bey (33): Pass
  - Arnold (6): Fail
  - Clint (86): Above average
  - Olivia (67): Average
  - Parah (59): Pass
  - Elijah (60): Average
  - Tom (10): Fail
  - John (85): Above average
  - Kanee (5): Fail
  - Reese (73): Average
  - Swan (100): Exceptional
  - 50 Dollar (32): Pass
  
  I'll click on F10 first to fix Benedict's grade.

  - The formula bar shows "PassPass" indicating corrupted data
  - The Message column (F) still shows mixed/corrupted grades like "42 Pass", "94 ExcellentPass", etc.
  - I need to properly clear and re-enter all grades in column F for rows 10-23
  
  #### 情况分析与思考过程
  
  The previous action selected the wrong cell (F9 instead of F10). I need to:
  1. Click on the correct cell F10 (Benedict's row)
  2. Clear it properly using Delete key
  3. Enter "Pass" 
  4. Continue with the remaining students
  
  Let me click on F10 first to ensure I'm on the right cell, then systematically fix all grades.

  #### 重要信息
  
  - LibreOffice Calc is open with student grades spreadsheet
  - Cell F9 is still selected (as shown in cell reference box), not F10
  - The formula bar shows "PassPass" indicating corrupted/concatenated data
  - Column F (Message/Remarks) contains mixed data: "42 Pass", "94 ExcellentPass", "33 Fail", etc.
  - The previous click coordinates didn't hit the correct cell
  - I need to properly select cell F10 (Benedict's row in the Message column) and fix all grades
  
  #### 情况分析与思考过程
  
  The previous attempts to click on F10 haven't been successful - I'm still on F9. I need to:
  1. Click on the correct cell F10 (Benedict's grade in the Message column)
  2. Clear it and enter the correct grade
  3. Continue with all remaining students (rows 10-23)
  
  Looking at the spreadsheet layout from the screenshot:
  - Column F is the Remarks/Message column
  - Row 10 is Benedict's data row
  - I need to click at the intersection of column F and row 10
  
  Let me try clicking at a coordinate that should properly hit F10. Based on the visible grid, I should click slightly lower to hit row 10 instead of row 9.
  
  Correct grades for all students:
  - Benedict (42): Pass
  - Blake (94): Excellent  
  - Bey (33): Pass
  - Arnold (6): Fail
  - Clint (86): Above average
  - Olivia (67): Average
  - Parah (59): Pass

  #### 重要信息
  
  - LibreOffice Calc is open with student grades spreadsheet
  - Cell F10 now correctly shows "Pass" for Benedict (the formula bar confirms this)
  - The previous action successfully corrected F10
  - Now I need to continue with F11 (Blake's grade)
  - Blake has a mark of 94, which should be "Excellent" according to the scale (90-99)
  
  #### 情况分析与思考过程
  
  Good progress! F10 is now correctly showing "Pass" for Benedict. Now I need to continue systematically fixing the remaining cells. 
  
  Looking at the visible data:
  - Row 11: Blake with mark 94 → should be "Excellent"
  - Row 12: Bey with mark 33 → should be "Pass"
  - Row 13: Arnold with mark 6 → should be "Fail"
  - And so on...
  
  I'll move to F11 and correct Blake's grade. I'll press Down arrow to move from F10 to F11, then clear and enter "Excellent".
  
  Actually, looking more carefully at the screen, I can see that row 11 (Blake) currently shows some corrupted text. I should click on F11 specifically to make sure I'm on the right cell, then clear it and enter "Excellent".
  ```
