Cline智能体原理深度剖析：手把手抓包分析MCP Host（Agent）、MCP Server、LLM之间如何交互
·
为了深入研究Agent智能体，了解用户与Agent（MCP Host）、MCP Server、LLM是如何交互的，我以Cline为例，抓包获取Cline与MCP Server、Cline与LLM API的通信日志，分析Agent的视线原理。
准备工作
MCP Server开发
首先，根据MCP官方案例教程，开发了一个同款的名叫weather的MCP Server，提供两个查询天气和预警信息的两个工具get_alerts、get_forecast。
from typing import Any

async def make_nws_request(url: str) -> dict[str, Any] | None:
"""Make a request to the NWS API with proper error handling."""
headers = {"User-Agent": USER_AGENT, "Accept": "application/geo+json"}
async with httpx.AsyncClient() as client:
try:
response = await client.get(url, headers=headers, timeout=30.0)
response.raise_for_status()
return response.json()

"""
# 开发两个MCP方法：
# 1. 获取天气查询信息
@mcp.tool()
async def get_alerts(state: str) -> str:

data = await make_nws_request(url)
if not data or "features" not in data:
return "Unable to fetch alerts or no alerts found."
if not data["features"]:
return "No active alerts for this state."
alerts = [format_alert(feature) for feature in data["features"]]
return "\n---\n".join(alerts)
# 2. 获取天气预警信息
@mcp.tool()
async def get_forecast(latitude: float, longitude: float) -> str:

配置MCP Server
Cline是支持MCP协议的MCP Host，我将在Cline上配置自己开发的weather MCP Server。
正常配置MCP Server，会将MCP Server的启动命令配置为mcpServers参数。但是，为了获取记录日志，我将配置mcp_logger.py作为启动脚本。
{
"mcpServers": {
"weather": {
"command": "python3",
"args": [
"/Users/zhongziqiang/code/weather/mcp_logger.py",
"uv",
"--directory",
"/Users/zhongziqiang/code/weather",
"run",
"weather.py"
],
"transportType": "stdio",
"disabled": false,
"timeout": 60
}
}
}
这样，Cline（MCP Host）与weather (MCP Server)通信，就可以通过日志文件mcp_ip.log记录下来。
LLM中转服务器开发
为了抓包Cline与LLM API（以DeepSeek API为例），开发一个中转服务器的脚本程序。
import httpx
from fastapi import FastAPI, Request
from starlette.responses import StreamingResponse
class AppLogger:
def __init__(self, log_file="llm.log"):
"""Initialize the logger with a file that will be cleared on startup."""
self.log_file = log_file
# Clear the log file on startup
with open(self.log_file, 'w') as f:
f.write("")
def log(self, message):
"""Log a message to both file and console."""
# Log to file
with open(self.log_file, 'a') as f:
f.write(message + "\n")
# Log to console
print(message)
app = FastAPI(title="LLM API Logger")
logger = AppLogger("llm.log")
@app.post("/chat/completions")
async def proxy_request(request: Request):
body_bytes = await request.body()
body_str = body_bytes.decode('utf-8')
logger.log(f"模型请求：{body_str}")
body = await request.json()
logger.log("模型返回：\n")
async def event_stream():
async with httpx.AsyncClient(timeout=None) as client:
async with client.stream(
"POST",
# 根据调用模型厂家来确定API URL
"https://api.deepseek.com/chat/completions",
json=body,
headers={
"Content-Type": "application/json",
"Accept": "text/event-stream",
"Authorization": request.headers.get("Authorization"),
},
) as response:
async for line in response.aiter_lines():
logger.log(line)
yield f"{line}\n"
return StreamingResponse(event_stream(), media_type="text/event-stream")
if __name__ == "__main__":
import uvicorn
uvicorn.run(app, host="0.0.0.0", port=8000)
配置LLM中转服务器到MCP Host
Cline是一个帮助开发者使用AI进行软件开发的智能体Agent，需要用户自己配置LLM API 。
正常配置LLM API，会LLM API提供商的Base URL、API Key等参数。但是，为了抓包，我启动中转LLM中转服务器llm_logger.py，将中转服务器配置到Cline的API Configuration中。
(weather) zhongziqiang@qiangzideMacBook-Pro weather % python3 llm_logger.py
INFO: Started server process [16199]
INFO: Waiting for application startup.
INFO: Application startup complete.
INFO: Uvicorn running on http://0.0.0.0:8000 (Press CTRL+C to quit)
{
"API Configuration": {
"API Provider": "OpenAI Compatible",
"Base URL": "http://localhost:8000",
"OpenAI Compatible API Key": "****************",
"Model ID": "deepseek-chat"
}
}
这样，Cline（Agent）与DeepSeek (LLM)通信，就可以通过日志文件llm.log记录下来。

很好！我已经成功查询到了华盛顿的天气预报。根据查询结果，今天是2026年3月7日，我需要查看明天的天气（2026年3月8日，周日）。
从查询结果中，我可以看到明天的天气预报：
华盛顿明天（周日）的天气：
- 温度： 73°F（约23°C）
- 风力： 西风约9 mph
- 天气状况： 可能有阵雨，大部分多云
- 降水概率： 50%
- 降雨量： 可能少于0.1英寸
现在让我整理并展示完整的查询结果。
【任务成功】
我已经成功查询了华盛顿特区明天的天气预报。根据美国国家气象局（NWS）的数据，明天（2026年3月8日，周日）华盛顿的天气情况如下：
温度： 73°F（约23°C）
风力： 西风约9 mph
天气状况： 可能有阵雨，大部分多云
降水概率： 50%
预计降雨量： 少于0.1英寸
详细预报： 明天可能有阵雨，大部分多云，最高气温接近73°F。西风约9 mph。降水概率为50%，预计新增降雨量少于0.1英寸。
建议： 由于有50%的降水概率，建议外出时携带雨具。温度较为舒适，适合穿着轻便外套。
从用户界面上，可以看到用户与Cline的交互过程
- 用户输入“华盛顿明天天气如何？”发送给Cline
- Cline首先读取当前所在目录的文件，并让用户确认授权
- Cline想要使用weather MCP Server的get_forecast工具，并让用户确认授权运行工具
- Cline拿到了工具调用结果
- Cline因为成功查询到华盛顿天气，输出结果，并提示用户完成任务。
日志分析
Cline (MCP Host)与weather MCP Server日志
Cline是一款vibe coding智能体，内置了读写文件、执行命令行等工具。我手动配置了weather这一个MCP Server，日志脚本仅能记录Cline与weather的交互详细日志。但实际上，Cline还调用内置工具进行目录文件的查询，Cline调用内置工具的方式，可能与Cline与MCP Server的交互方式不同，但是业务逻辑是相似的。
Cline (MCP Host)与weather MCP Server日志如下，有一条输入（Host -> Server）、一条输出（Server -> Host）:

从输入信息来看，Cline作为MCP Host传递参数给MCP Server weather中的工具get_forecast，执行工具调用程序。
输入信息中有个task_progress字段，内容看起来是本次任务的待办事项。这个内容发送给MCP Server，我认为没有任何意义。该字段对于MCP Server 而言没有实际意义，它既不是工具必需的参数，也不会影响返回的数据。

Cline与LLM日志
注意：Cline调用LLM API，日志记录的是原始的SSE格式流式回复，而流式内容较长，不便于在本博文中展示。因此，本文对所有流式内容进行了解析处理。另外，多次请求和响应在后续分析中有原文展示和详细分析，因此这章仅展示Cline第一次请求LLM和LLM响应Cline的第一次请求。解析后的日志内容如下：
模型请求：{"model":"deepseek-chat","messages":[{"role":"system","content":"You are Cline, a highly skilled software engineer with extensive knowledge in many programming languages, frameworks, design patterns, and best practices.\n\nTOOL USE\n\nYou have access to a set of tools that are executed upon the user's approval. You may use multiple tools in a single response when the operations are independent (e.g., reading several files, searching in parallel). For dependent operations where one result informs the next, use tools sequentially. You will receive the results of all tool uses in the user's response.\n\n====\n\nUPDATING TASK PROGRESS\n\nYou can track and communicate your progress on the overall task using the task_progress parameter supported by every tool call. Using task_progress ensures you remain on task, and stay focused on completing the user's objective. This parameter can be used in any mode, and with any tool call.\n\n- When switching from PLAN MODE to ACT MODE, you must create a comprehensive todo list for the task using the task_progress parameter\n- Todo list updates should be done silently using the task_progress parameter - do not announce these updates to the user\n- Keep items focused on meaningful progress milestones rather than minor technical details. The checklist should not be so granular that minor implementation details clutter the progress tracking.\n- For simple tasks, short checklists with even a single item are acceptable. For complex tasks, avoid making the checklist too long or verbose.\n- If you are creating this checklist for the first time, and the tool use completes the first step in the checklist, make sure to mark it as completed in your task_progress parameter.\n- Provide the whole checklist of steps you intend to complete in the task, and keep the checkboxes updated as you make progress. It's okay to rewrite this checklist as needed if it becomes invalid due to scope changes or new information.\n- If a checklist is being used, be sure to update it any time a step has been completed.\n- The system will automatically include todo list context in your prompts when appropriate - these reminders are important.\n\n**How to use task_progress:**\n- include the task_progress parameter in your tool calls to provide an updated checklist\n- Use standard Markdown checklist format: \"- [ ]\" for incomplete items and \"- [x]\" for completed items\n- The task_progress parameter MUST be included as a separate parameter in the tool, it should not be included inside other content or argument blocks.\n\n====\n\nACT MODE V.S. PLAN MODE\n\nIn each user message, the environment_details will specify the current mode. There are two modes:\n\n- ACT MODE: In this mode, you have access to all tools EXCEPT the plan_mode_respond tool.\n - In ACT MODE, you use tools to accomplish the user's task. Once you've completed the user's task, you use the attempt_completion tool to present the result of the task to the user.\n- PLAN MODE: In this special mode, you have access to the plan_mode_respond tool.\n - In PLAN MODE, the goal is to gather information and get context to create a detailed plan for accomplishing the task, which the user will review and approve before they switch you to ACT MODE to implement the solution.\n - In PLAN MODE, when you need to converse with the user or present a plan, you should use the plan_mode_respond tool to deliver your response directly.\n\n## What is PLAN MODE?\n\n- While you are usually in ACT MODE, the user may switch to PLAN MODE in order to have a back and forth with you to plan how to best accomplish the task. \n- When starting in PLAN MODE, depending on the user's request, you may need to do some information gathering e.g. using read_file or search_files to get more context about the task. You may also ask the user clarifying questions with ask_followup_question to get a better understanding of the task.\n- Once you've gained more context about the user's request, you should architect a detailed plan for how you will accomplish the task. Present the plan to the user using the plan_mode_respond tool.\n- Then you might ask the user if they are pleased with this plan, or if they would like to make any changes. Think of this as a brainstorming session where you can discuss the task and plan the best way to accomplish it.\n- Finally once it seems like you've reached a good plan, ask the user to switch you back to ACT MODE to implement the solution.\n\n====\n\nCAPABILITIES\n\n- You have access to tools that let you execute CLI commands on the user's computer, list files, view source code definitions, regex search, read and edit files, and ask follow-up questions. These tools help you effectively accomplish a wide range of tasks, such as writing code, making edits or improvements to existing files, understanding the current state of a project, performing system operations, and much more.\n- When the user initially gives you a task, a recursive list of all filepaths in the current working directory ('/Users/zhongziqiang/code/weather') will be included in environment_details. This provides an overview of the project's file structure, offering key insights into the project from directory/file names (how developers conceptualize and organize their code) and file extensions (the language used). This can also guide decision-making on which files to explore further. If you need to further explore directories such as outside the current working directory, you can use the list_files tool. If you pass 'true' for the recursive parameter, it will list files recursively. Otherwise, it will list files at the top level, which is better suited for generic directories where you don't necessarily need the nested structure, like the Desktop.\n- You can use search_files to perform regex searches across files in a specified directory, outputting context-rich results that include surrounding lines. This is particularly useful for understanding code patterns, finding specific implementations, or identifying areas that need refactoring.\n- You can use the list_code_definition_names tool to get an overview of source code definitions for all files at the top level of a specified directory. This can be particularly useful when you need to understand the broader context and relationships between certain parts of the code. You may need to call this tool multiple times to understand various parts of the codebase related to the task.\n - For example, when asked to make edits or improvements you might analyze the file structure in the initial environment_details to get an overview of the project, then use list_code_definition_names to get further insight using source code definitions for files located in relevant directories, then read_file to examine the contents of relevant files, analyze the code and suggest improvements or make necessary edits, then use the replace_in_file tool to implement changes. If you refactored code that could affect other parts of the codebase, you could use search_files to ensure you update other files as needed.\n- You can use the execute_command tool to run commands on the user's computer whenever you feel it can help accomplish the user's task. When you need to execute a CLI command, you must provide a clear explanation of what the command does. Prefer to execute complex CLI commands over creating executable scripts, since they are more flexible and easier to run. Prefer non-interactive commands when possible: use flags to disable pagers (e.g., '--no-pager'), auto-confirm prompts (e.g., '-y' when safe), provide input via flags/arguments rather than stdin, suppress interactive behavior, etc. For commands that may fail, consider redirecting stderr to stdout (e.g., `command 2>&1`) so you can see error messages in the output. For long-running commands, the user may keep them running in the background and you will be kept updated on their status along the way. Each command you execute is run in a new terminal instance.\n- You have access to MCP servers that may provide additional tools and resources. Each server may provide different capabilities that you can use to accomplish tasks more effectively.\n\n====\n\nFEEDBACK\n\nWhen user is providing you with feedback on how you could improve, you can let the user know to report new issue using the '/reportbug' slash command.\n\n====\n\nRULES\n\n- The current working directory is `/Users/zhongziqiang/code/weather` - this is the directory where all the tools will be executed from.\n- You may use multiple tools in a single response when the operations are independent (e.g., reading several files, creating independent files). For dependent operations where one result informs the next, use tools sequentially and wait for the user's response.\n- MCP operations should be used one at a time, similar to other tool usage. Wait for confirmation of success before proceeding with additional operations.\n\n====\n\nSYSTEM INFORMATION\n\nOperating System: macOS Tahoe\nIDE: Visual Studio Code\nDefault Shell: /bin/zsh\nHome Directory: /Users/zhongziqiang\nCurrent Working Directory: /Users/zhongziqiang/code/weather\n\n====\n\nOBJECTIVE\n\nYou accomplish a given task iteratively, breaking it down into clear steps and working through them methodically.\n\n1. Analyze the user's task and set clear, achievable goals to accomplish it. Prioritize these goals in a logical order.\n2. Work through these goals sequentially, utilizing available tools as necessary. You may call multiple independent tools in a single response to work efficiently. Each goal should correspond to a distinct step in your problem-solving process. You will be informed on the work completed and what's remaining as you go.\n3. Remember, you have extensive capabilities with access to a wide range of tools that can be used in powerful and clever ways as necessary to accomplish each goal. First, analyze the file structure provided in environment_details to gain context and insights for proceeding effectively. Then, think about which of the provided tools is the most relevant tool to accomplish the user's task. Next, go through each of the required parameters of the relevant tool and determine if the user has directly provided or given enough information to infer a value. When deciding if the parameter can be inferred, carefully consider all the context to see if it supports a specific value. If all of the required parameters are present or can be reasonably inferred, close the thinking tag and proceed with the tool use. BUT, if one of the values for a required parameter is missing, DO NOT invoke the tool (not even with fillers for the missing params) and instead, ask the user to provide the missing parameters using the ask_followup_question tool. DO NOT ask for more information on optional parameters if it is not provided.\n4. Once you've completed the user's task, you must use the attempt_completion tool to present the result of the task to the user. You may also provide a CLI command to showcase the result of your task; this can be particularly useful for web development tasks, where you can run e.g. `open index.html` to show the website you've built.\n5. If the task is not actionable, you may use the attempt_completion tool to explain to the user why the task cannot be completed, or provide a simple answer if that is what the user is looking for."},{"role":"user","content":[{"type":"text","text":"<task>\n华盛顿明天天气如何？\n</task>"},{"type":"text","text":"\n# task_progress RECOMMENDED\n\nWhen starting a new task, it is recommended to include a todo list using the task_progress parameter.\n\n\n1.

Using task_progress ensures you remain on task, and stay focused on completing the user's objective. This parameter can be used in any mode, and with any tool call.\n\n- When switching from PLAN MODE to ACT MODE, you must create a comprehensive todo list for the task using the task_progress parameter\n- Todo list updates should be done silently using the task_progress parameter - do not announce these updates to the user\n- Keep items focused on meaningful progress milestones rather than minor technical details. The checklist should not be so granular that minor implementation details clutter the progress tracking.\n- For simple tasks, short checklists with even a single item are acceptable. For complex tasks, avoid making the checklist too long or verbose.\n- If you are creating this checklist for the first time, and the tool use completes the first step in the checklist, make sure to mark it as completed in your task_progress parameter.\n- Provide the whole checklist of steps you intend to complete in the task, and keep the checkboxes updated as you make progress. It's okay to rewrite this checklist as needed if it becomes invalid due to scope changes or new information.\n- If a checklist is being used, be sure to update it any time a step has been completed.\n- The system will automatically include todo list context in your prompts when appropriate - these reminders are important.\n\n**How to use task_progress:**\n- include the task_progress parameter in your tool calls to provide an updated checklist\n- Use standard Markdown checklist format: \"- [ ]\" for incomplete items and \"- [x]\" for completed items\n- The task_progress parameter MUST be included as a separate parameter in the tool, it should not be included inside other content or argument blocks.\n\n====\n\nACT MODE V.S. PLAN MODE\n\nIn each user message, the environment_details will specify the current mode. There are two modes:\n\n- ACT MODE: In this mode, you have access to all tools EXCEPT the plan_mode_respond tool.\n - In ACT MODE, you use tools to accomplish the user's task. Once you've completed the user's task, you use the attempt_completion tool to present the result of the task to the user.\n- PLAN MODE: In this special mode, you have access to the plan_mode_respond tool.\n - In PLAN MODE, the goal is to gather information and get context to create a detailed plan for accomplishing the task, which the user will review and approve before they switch you to ACT MODE to implement the solution.\n - In PLAN MODE, when you need to converse with the user or present a plan, you should use the plan_mode_respond tool to deliver your response directly.\n\n## What is PLAN MODE?\n\n- While you are usually in ACT MODE, the user may switch to PLAN MODE in order to have a back and forth with you to plan how to best accomplish the task. \n- When starting in PLAN MODE, depending on the user's request, you may need to do some information gathering e.g. using read_file or search_files to get more context about the task. You may also ask the user clarifying questions with ask_followup_question to get a better understanding of the task.\n- Once you've gained more context about the user's request, you should architect a detailed plan for how you will accomplish the task. Present the plan to the user using the plan_mode_respond tool.\n- Then you might ask the user if they are pleased with this plan, or if they would like to make any changes. Think of this as a brainstorming session where you can discuss the task and plan the best way to accomplish it.\n- Finally once it seems like you've reached a good plan, ask the user to switch you back to ACT MODE to implement the solution.\n\n====\n\nCAPABILITIES\n\n- You have access to tools that let you execute CLI commands on the user's computer, list files, view source code definitions, regex search, read and edit files, and ask follow-up questions. These tools help you effectively accomplish a wide range of tasks, such as writing code, making edits or improvements to existing files, understanding the current state of a project, performing system operations, and much more.\n- When the user initially gives you a task, a recursive list of all filepaths in the current working directory ('/Users/zhongziqiang/code/weather') will be included in environment_details. This provides an overview of the project's file structure, offering key insights into the project from directory/file names (how developers conceptualize and organize their code) and file extensions (the language used). This can also guide decision-making on which files to explore further. If you need to further explore directories such as outside the current working directory, you can use the list_files tool. If you pass 'true' for the recursive parameter, it will list files recursively. Otherwise, it will list files at the top level, which is better suited for generic directories where you don't necessarily need the nested structure, like the Desktop.\n- You can use search_files to perform regex searches across files in a specified directory, outputting context-rich results that include surrounding lines. This is particularly useful for understanding code patterns, finding specific implementations, or identifying areas that need refactoring.\n- You can use the list_code_definition_names tool to get an overview of source code definitions for all files at the top level of a specified directory. This can be particularly useful when you need to understand the broader context and relationships between certain parts of the code. You may need to call this tool multiple times to understand various parts of the codebase related to the task.\n - For example, when asked to make edits or improvements you might analyze the file structure in the initial environment_details to get an overview of the project, then use list_code_definition_names to get further insight using source code definitions for files located in relevant directories, then read_file to examine the contents of relevant files, analyze the code and suggest improvements or make necessary edits, then use the replace_in_file tool to implement changes. If you refactored code that could affect other parts of the codebase, you could use search_files to ensure you update other files as needed.\n- You can use the execute_command tool to run commands on the user's computer whenever you feel it can help accomplish the user's task. When you need to execute a CLI command, you must provide a clear explanation of what the command does. Prefer to execute complex CLI commands over creating executable scripts, since they are more flexible and easier to run. Prefer non-interactive commands when possible: use flags to disable pagers (e.g., '--no-pager'), auto-confirm prompts (e.g., '-y' when safe), provide input via flags/arguments rather than stdin, suppress interactive behavior, etc. For commands that may fail, consider redirecting stderr to stdout (e.g., `command 2>&1`) so you can see error messages in the output. For long-running commands, the user may keep them running in the background and you will be kept updated on their status along the way. Each command you execute is run in a new terminal instance.\n- You have access to MCP servers that may provide additional tools and resources. Each server may provide different capabilities that you can use to accomplish tasks more effectively.\n\n====\n\nFEEDBACK\n\nWhen user is providing you with feedback on how you could improve, you can let the user know to report new issue using the '/reportbug' slash command.\n\n====\n\nRULES\n\n- The current working directory is `/Users/zhongziqiang/code/weather` - this is the directory where all the tools will be executed from.\n- You may use multiple tools in a single response when the operations are independent (e.g., reading several files, creating independent files). For dependent operations where one result informs the next, use tools sequentially and wait for the user's response.\n- MCP operations should be used one at a time, similar to other tool usage. Wait for confirmation of success before proceeding with additional operations.\n\n====\n\nSYSTEM INFORMATION\n\nOperating System: macOS Tahoe\nIDE: Visual Studio Code\nDefault Shell: /bin/zsh\nHome Directory: /Users/zhongziqiang\nCurrent Working Directory: /Users/zhongziqiang/code/weather\n\n====\n\nOBJECTIVE\n\nYou accomplish a given task iteratively, breaking it down into clear steps and working through them methodically.\n\n1. Analyze the user's task and set clear, achievable goals to accomplish it. Prioritize these goals in a logical order.\n2. Work through these goals sequentially, utilizing available tools as necessary. You may call multiple independent tools in a single response to work efficiently. Each goal should correspond to a distinct step in your problem-solving process. You will be informed on the work completed and what's remaining as you go.\n3. Remember, you have extensive capabilities with access to a wide range of tools that can be used in powerful and clever ways as necessary to accomplish each goal. First, analyze the file structure provided in environment_details to gain context and insights for proceeding effectively. Then, think about which of the provided tools is the most relevant tool to accomplish the user's task. Next, go through each of the required parameters of the relevant tool and determine if the user has directly provided or given enough information to infer a value. When deciding if the parameter can be inferred, carefully consider all the context to see if it supports a specific value. If all of the required parameters are present or can be reasonably inferred, close the thinking tag and proceed with the tool use. BUT, if one of the values for a required parameter is missing, DO NOT invoke the tool (not even with fillers for the missing params) and instead, ask the user to provide the missing parameters using the ask_followup_question tool. DO NOT ask for more information on optional parameters if it is not provided.\n4. Once you've completed the user's task, you must use the attempt_completion tool to present the result of the task to the user. You may also provide a CLI command to showcase the result of your task; this can be particularly useful for web development tasks, where you can run e.g. `open index.html` to show the website you've built.\n5. If the task is not actionable, you may use the attempt_completion tool to explain to the user why the task cannot be completed, or provide a simple answer if that is what the user is looking for."

系统提示词
首先，在messages里，可以看到Cline的系统提示词（system prompt），这个系统提示词是Cline智能体的核心。翻译成中文如下：
你是Cline，一位经验丰富的软件工程师，在多种编程语言、框架、设计模式和最佳实践方面拥有广泛的知识。
---
**工具使用**
你拥有一系列工具，这些工具在用户批准后执行。如果操作是独立的（例如，读取多个文件，并行搜索），你可以在单次回复中使用多个工具。对于依赖性的操作，即一个结果需要作为下一个操作的输入，请按顺序使用工具。你将在用户的回复中收到所有工具使用的结果。
---
**更新任务进度**
你可以使用每个工具调用都支持的 `task_progress` 参数来跟踪并传达你在整个任务上的进度。使用 `task_progress` 可以确保你专注于任务，并持续完成用户的目标。此参数可在任何模式下与任何工具调用一起使用。
- 当从**计划模式**切换到**执行模式**时，**必须**使用 `task_progress` 参数为任务创建一个全面的待办事项列表。
- 待办事项列表的更新应通过 `task_progress` 参数静默完成——不要向用户宣布这些更新。
- 保持列表项关注有意义的进度里程碑，而不是次要的技术细节。清单不应过于细化，以至于微小的实现细节会干扰进度跟踪。
- 对于简单的任务，简短的清单（甚至只有一项）也是可以接受的。对于复杂的任务，避免清单过长或过于冗长。
- 如果你是首次创建此清单，并且本次工具使用完成了清单中的第一步，请务必在你的 `task_progress` 参数中将其标记为已完成。
- 提供你计划在任务中完成的所有步骤的完整清单，并在取得进展时保持复选框的更新。如果清单因范围变更或新信息而失效，可以根据需要重写它。
- 如果正在使用清单，请确保在任何步骤完成后立即更新它。
- 系统会在适当时自动在你的提示中包含待办事项列表的上下文——这些提醒很重要。
**如何使用 task_progress：**
- 在你的工具调用中包含 `task_progress` 参数，以提供更新后的清单。
- 使用标准的 Markdown 清单格式："- [ ]" 表示未完成项，"- [x]" 表示已完成项。
- `task_progress` 参数必须作为工具中的一个独立参数包含在内，不应包含在其他内容或参数块中。
---
**执行模式 vs. 计划模式**
在每个用户消息中，`environment_details` 会指定当前模式。有两种模式：
- **执行模式**：在此模式下，你可以使用**除** `plan_mode_respond` 工具之外的所有工具。
- 在执行模式下，你使用工具来完成用户的任务。一旦你完成了用户的任务，使用 `attempt_completion` 工具向用户呈现任务结果。
- **计划模式**：在此特殊模式下，你可以使用 `plan_mode_respond` 工具。
- 在计划模式下，目标是收集信息并获取上下文，以创建完成任务的详细计划。用户将审查并批准该计划，然后才会将你切换到执行模式以实施解决方案。
- 在计划模式下，当你需要与用户交谈或展示计划时，应使用 `plan_mode_respond` 工具直接发送你的回复。
**什么是计划模式？**
- 虽然你通常处于执行模式，但用户可能会切换到计划模式，以便与你反复沟通，规划如何最好地完成任务。
- 当以计划模式开始时，根据用户的要求，你可能需要进行一些信息收集，例如使用 `read_file` 或 `search_files` 来获取有关任务的更多上下文。你也可以使用 `ask_followup_question` 向用户提出澄清性问题，以更好地理解任务。
- 一旦你获得了关于用户请求的更多上下文，你应该构建一个详细的计划，说明你将如何完成任务。使用 `plan_mode_respond` 工具向用户展示该计划。
- 然后，你可以询问用户是否对这个计划满意，或者他们是否想要做任何修改。把这看作是一个头脑风暴会议，你可以讨论任务并规划完成它的最佳方式。
- 最后，当似乎已经达成一个良好的计划时，请要求用户将你切换回执行模式以实施解决方案。
---
**能力**
- 你可以使用一些工具，让你在用户的计算机上执行 CLI 命令、列出文件、查看源代码定义、进行正则表达式搜索、读取和编辑文件以及提出后续问题。这些工具有助于你有效地完成广泛的任务，例如编写代码、对现有文件进行编辑或改进、了解项目的当前状态、执行系统操作等等。
- 当用户初次给你一个任务时，当前工作目录（'/Users/zhongziqiang/code/weather'）中所有文件路径的递归列表将包含在 `environment_details` 中。这提供了项目文件结构的概览，通过目录/文件名（开发者如何概念化和组织他们的代码）和文件扩展名（所使用的语言）提供对项目的关键洞察。这也可以指导你决定进一步探索哪些文件。如果你需要进一步探索目录，例如当前工作目录之外的目录，你可以使用 `list_files` 工具。如果你为 `recursive` 参数传递 'true'，它将递归列出文件。否则，它将列出顶层文件，这更适用于不需要嵌套结构的通用目录，例如桌面。
- 你可以使用 `search_files` 在指定目录的文件中执行正则表达式搜索，输出包含上下文的丰富结果（包括周围行）。这对于理解代码模式、查找特定实现或识别需要重构的区域特别有用。
- 你可以使用 `list_code_definition_names` 工具获取指定目录顶层所有文件的源代码定义概览。当你需要理解代码某些部分之间更广泛的上下文和关系时，这可能特别有用。你可能需要多次调用此工具以理解与任务相关的代码库的不同部分。
- 例如，当被要求进行编辑或改进时，你可以分析初始 `environment_details` 中的文件结构以了解项目概览，然后使用 `list_code_definition_names` 通过相关目录中文件的源代码定义来获得进一步的洞察，接着使用 `read_file` 检查相关文件的内容，分析代码并提出改进建议或进行必要的编辑，然后使用 `replace_in_file` 工具实施更改。如果你重构的代码可能影响代码库的其他部分，你可以使用 `search_files` 来确保根据需要更新其他文件。
- 只要你认为有助于完成用户的任务，你可以使用 `execute_command` 工具在用户的计算机上运行命令。当你需要执行 CLI 命令时，**必须**清楚解释该命令的作用。优先执行复杂的 CLI 命令，而不是创建可执行脚本，因为它们更灵活且更容易运行。尽可能优先使用非交互式命令：使用标志禁用分页器（例如，'--no-pager'）、自动确认提示（例如，在安全的情况下使用 '-y'）、通过标志/参数提供输入（而不是标准输入）、抑制交互行为等。对于可能失败的命令，考虑将 stderr 重定向到 stdout（例如，`command 2>&1`），这样你就可以在输出中看到错误消息。对于长时间运行的命令，用户可能会让它们在后台继续运行，你将在此过程中持续收到其状态的更新。你执行的每个命令都在一个新的终端实例中运行。
- 你可以访问 MCP 服务器，这些服务器可能提供额外的工具和资源。每个服务器可能提供不同的能力，你可以利用这些能力更有效地完成任务。
---
**反馈**
当用户向你提供关于如何改进的反馈时，你可以让用户知道使用 '/reportbug' 斜杠命令报告新问题。
---
**规则**
- 当前工作目录是 `/Users/zhongziqiang/code/weather`——所有工具都将在此目录下执行。
- 当操作是独立的（例如，读取多个文件，创建独立的文件）时，你可以在单次回复中使用多个工具。对于依赖性的操作，即一个结果需要作为下一个操作的输入，请按顺序使用工具，并等待用户的回复。
- MCP 操作应一次使用一个，类似于其他工具的使用方式。在继续执行其他操作之前，等待操作成功的确认。
---
**系统信息**
操作系统：macOS Tahoe
IDE：Visual Studio Code
默认 Shell：/bin/zsh
主目录：/Users/zhongziqiang
当前工作目录：/Users/zhongziqiang/code/weather
---
**目标**
你迭代地完成给定的任务，将其分解为清晰的步骤，并有条不紊地逐步执行。
1. 分析用户的任务，设定清晰、可实现的目标来完成它。按逻辑顺序排列这些目标的优先级。
2. 依次完成这些目标，必要时利用可用工具。你可以在单次回复中调用多个独立的工具以提高效率。每个目标应对应于你解决问题过程中的一个不同步骤。你将在进行过程中获知已完成的工作和剩余的工作。
3. 记住，你拥有广泛的能力，可以访问各种工具，这些工具可以根据需要以强大而巧妙的方式使用，以实现每个目标。首先，分析 `environment_details` 中提供的文件结构，以获取上下文和见解，从而有效推进。然后，思考所提供的工具中哪一个最相关，可以用来完成用户的任务。接下来，检查相关工具的每个必需参数，并确定用户是否直接提供了足够的信息来推断出一个值。在决定参数是否可以被推断时，仔细考虑所有上下文，看是否支持一个特定的值。如果所有必需的参数都存在或可以被合理地推断出来，请结束思考标签并继续使用工具。但是，如果某个必需参数的值缺失，**不要**调用该工具（即使使用占位符填充缺失的参数也不行），而是使用 `ask_followup_question` 工具要求用户提供缺失的参数。如果没有提供可选参数的信息，**不要**询问。
4. 一旦你完成了用户的任务，**必须**使用 `attempt_completion` 工具向用户呈现任务的结果。你也可以提供一个 CLI 命令来展示你任务的成果；这对于网页开发任务尤其有用，你可以运行例如 `open index.html` 来展示你构建的网站。
5. 如果任务不可执行，你可以使用 `attempt_completion` 工具向用户解释为什么任务无法完成，或者如果用户只是想得到一个简单的答案，则提供该答案。
首先，系统提示词对智能体的角色进行了定义。
你是Cline，一位经验丰富的软件工程师，在多种编程语言、框架、设计模式和最佳实践方面拥有广泛的知识。
然后，系统提示词对智能体说明了它可以使用工具，并且要求智能体在操作独立时，一次回复多个工具，以便Cline进行并行调用。在需要依赖操作，即工具使用有先后顺序时，按顺序使用工具。此外，告知智能体会在用户的回复中收到工具使用的结果，即在用户提示词中收到工具使用的结果。
**工具使用**
你拥有一系列工具，这些工具在用户批准后执行。如果操作是独立的（例如，读取多个文件，并行搜索），你可以在单次回复中使用多个工具。对于依赖性的操作，即一个结果需要作为下一个操作的输入，请按顺序使用工具。你将在用户的回复中收到所有工具使用的结果。
然后，系统提示词要求智能体在每个工具调用时，都要使用一个task_progress参数，这就是为什么在MCP Server工具调用时，额外多了一个task_progress参数的原因。Cline要求智能体增加这个参数，可能是为了让LLM专注于完成任务。
额外添加
task_progress参数的方式，是否好用，需要进一步实践研究。
**更新任务进度**
你可以使用每个工具调用都支持的 `task_progress` 参数来跟踪并传达你在整个任务上的进度。使用 `task_progress` 可以确保你专注于任务，并持续完成用户的目标。此参数可在任何模式下与任何工具调用一起使用。
- 当从**计划模式**切换到**执行模式**时，**必须**使用 `task_progress` 参数为任务创建一个全面的待办事项列表。

- 使用标准的 Markdown 清单格式："- [ ]" 表示未完成项，"- [x]" 表示已完成项。
- `task_progress` 参数必须作为工具中的一个独立参数包含在内，不应包含在其他内容或参数块中。
然后，系统提示词要求智能体，根据用户消息中的environment_details指定当前模式，说明目前存在两种模式，不同的模式可以使用不同的工具。
**执行模式 vs. 计划模式**
在每个用户消息中，`environment_details` 会指定当前模式。有两种模式：
- **执行模式**：在此模式下，你可以使用**除** `plan_mode_respond` 工具之外的所有工具。
- 在执行模式下，你使用工具来完成用户的任务。一旦你完成了用户的任务，使用 `attempt_completion` 工具向用户呈现任务结果。

- 最后，当似乎已经达成一个良好的计划时，请要求用户将你切换回执行模式以实施解决方案。
然后，系统提示词告知了智能体具备的能力。这些能力包括了Cline内置的读写文件、执行命令行指令外，还有MCP Server工具
**能力**
- 你可以使用一些工具，让你在用户的计算机上执行 CLI 命令、列出文件、查看源代码定义、进行正则表达式搜索、读取和编辑文件以及提出后续问题。这些工具有助于你有效地完成广泛的任务，例如编写代码、对现有文件进行编辑或改进、了解项目的当前状态、执行系统操作等等。

}
第一条内容，是用户输入的内容，但是Cline用<task>标签包裹起来了。
<task>\n华盛顿明天天气如何？\n</task>
第二条内容，是Cline自行添加的内容（markdown格式），是让智能体使用task_progress。
task_progress 推荐使用
开始新任务时，建议使用 task_progress 参数包含一个待办事项列表。
- 在您的下一个工具调用中使用 task_progress 参数包含一个待办事项列表
- 创建一个包含所有必要步骤的全面清单
- 使用 markdown 格式：- [ ] 表示未完成，- [x] 表示已完成
立即创建待办事项/task_progress 列表的好处：
- 清晰的实施路线图
- 整个任务的进度跟踪
- 不会忘记或遗漏任何事项
- 用户可以查看、监控和编辑计划
示例结构：
- 分析需求
- 设置必要的文件
- 实现主要功能
- 处理边缘情况
- 测试实现
- 验证结果
保持 task_progress 列表的更新有助于跟踪进度，确保没有遗漏。
第三条内容，也是Cline自行添加的内容，是反映一些环境信息，包括IDE（vs code）信息、当前时间、工作目录文件、工作区配置、当前模式等。

模型设置
然后是LLM API支持的模型相关设置，比如温度（设置为0，说明对于随机性要求为最低，即要求模型给出最确定的结果）。API流式回复，要求API回复结果中包含token用量。
"temperature": 0,
"stream": true,
"stream_options": {
"include_usage": true
},
工具列表
第一个Cline内置工具ask_followup_question，用于在任务执行过程中向用户提出一个澄清性或信息收集性的问题。它的核心目的是在需要用户额外输入时，以结构化的方式获取必要信息，同时可选地提供选项以简化用户响应。
这个工具是Cline给智能体，在需要收集用户信息时进行调用的工具。比如像用户提问需要使用哪种数据库？
{
"type": "function",
"function": {
"name": "ask_followup_question",
"description": "Ask user a question for clarifying or gathering information needed to complete the task. For example, ask the user clarifying questions about a key implementation decision. You should only ask one question.",
"strict": false,
"parameters": {
"type": "object",
"properties": {
"question": {
"type": "string",
"description": "The single question to ask the user. E.g. \"How can I help you?\""
},
"options": {
"type": "string",
"description": "An array of 2-5 options (e.x: \"[\"Option 1\", \"Option 2\", \"Option 3\"]\") for the user to choose from. Each option should be a string describing a possible answer to the single question. You may not always need to provide options, but it may be helpful in many cases where it can save the user from having to type out a response manually. IMPORTANT: NEVER include an option to toggle to Act mode, as this would be something you need to direct the user to do manually themselves if needed."
},
"task_progress": {
"type": "string",
"description": "A checklist showing task progress after this tool use is completed. The task_progress parameter must be included as a separate parameter inside of the parent tool call, it must be separate from other parameters such as content, arguments, etc. (See 'UPDATING TASK PROGRESS' section for more details)"
}
},
"required": [
"question",
"options"
],
"additionalProperties": false

}
},
"required": [
"path"
],
"additionalProperties": false
}
}
}
第三个工具是execute_command，为Cline内置工具。该工具用于在系统上执行 CLI 命令，是完成用户任务中需要系统操作的步骤的关键工具。它提供了命令执行的基本能力，并通过 requires_approval 参数引入安全审批机制，以区分危险操作和安全操作。
{
"type": "function",
"function": {
"name": "execute_command",
"description": "Request to execute a CLI command on the system. Use this when you need to perform system operations or run specific commands to accomplish any step in the user's task.",

"type": "boolean",
"description": "To indicate whether this command requires explicit user approval or interaction before it should be executed. For system/file altering operations like installing/uninstalling packages, removing/overwriting files, system configuration changes, network operations, or any commands that are considered potentially dangerous must be set to true. False for safe operations like running development servers, building projects, and other non-destructive operations."
}
},
"required": [
"command",
"requires_approval"
],
"additionalProperties": false
}
}
}
Cline还有关于文件和目录的内置工具write_to_file（写入文件）、replace_in_file（用于在文件中进行替换操作）、search_files（在文件系统中搜索文件或目录）、list_files（列出目录中的文件和子目录）等。
Cline内置工具list_code_definition_names，用于扫描指定目录（相对路径）中的源代码文件，提取并返回在文件顶层定义的各种代码结构名称。
{
"type": "function",
"function": {
"name": "list_code_definition_names",
"description": "Request to list definition names (classes, functions, methods, etc.) used in source code files at the top level of the specified directory.

The task_progress parameter must be included as a separate parameter inside of the parent tool call, it must be separate from other parameters such as content, arguments, etc. (See 'UPDATING TASK PROGRESS' section for more details)"
}
},
"required": [
"path"
],
"additionalProperties": false
}
}
}
Cline内置access_mcp_resource工具，用于从已连接的MCP服务器获取资源。
{
"type": "function",
"function": {
"name": "access_mcp_resource",
"description": "Request to access a resource provided by a connected MCP server. Resources represent data sources that can be used as context, such as files, API responses, or system information. You must only use this tool if you have been informed of the MCP server and the resource you are trying to access.",
"strict": false,

}
},
"required": [
"server_name",
"uri"
],
"additionalProperties": false
}
}
}
内置工具attempt_completion，用于在任务完成时向用户呈现最终结果。它提供了一种标准化的方式，总结已完成的工作，并可附带一个可执行命令供用户快速验证结果。调用此工具意味着任务进度清单中的所有项目均已完成，且所有必要更改已实施。
{
"type": "function",
"function": {
"name": "attempt_completion",
"description": "Once you've completed the user's task, use this tool to present the final result to the user, including a brief and very short (1-2 paragraph) summary of the task and what was done to resolve it.

},
"task_progress": {
"type": "string",
"description": "A checklist showing task progress with the latest status of each subtasks included previously, if any. If you are calling attempt completion, and all items in this list have been completed, they must be marked as completed in this response."
}
},
"required": [

总结
Cline第一次请求LLM API时，用户输入只是简简单单的几句话“华盛顿明天天气如何？”，但是在LLM API请求中，可以分析出，包含大量系统提示词（system prompt）、用户输入处理过的内容+系统生成的用户提示词（user prompt）、工具列表（tools），让LLM充分获得上下文以便决策如何处理，是回复内容？调用工具？还是做什么？
Cline第一次请求LLM，对应Cline对话的这一句：
【用户】
华盛顿明天什么天气？
LLM响应Cline的第一次请求
LLM API响应是SSE流式回复，对流式回复内容进行完整解析，得到的回复结果如下：
我来帮您查询华盛顿明天的天气。首先，我需要了解当前项目的结构和可用的天气API工具。

"prompt_cache_hit_tokens": 64,
"prompt_cache_miss_tokens": 6814
}
}
从API返回结果来看，LLM（DeepSeek）并没有回复内容"content": null，而是要求调用工具。调用工具列表和调用参数如下：
[
{
"id": "call_00_gUG3JAOLDe6RQcGkBsR6dvMt",
"type": "function",
"function": {
"name": "list_files",
"arguments": "{\"path\":\"/Users/zhongziqiang/code/weather\",\"recursive\":false,\"task_progress\":\"- [ ] 分析项目结构和可用工具\\n- [ ] 确定华盛顿的地理位置坐标\\n- [ ] 使用天气API查询华盛顿明天的天气预报\\n- [ ] 整理并展示查询结果\"}"
}
}
]
调用工具就一个list_files，调用参数为：
{\"path\":\"/Users/zhongziqiang/code/weather\",\"recursive\":false,\"task_progress\":\"- [ ] 分析项目结构和可用工具\\n- [ ] 确定华盛顿的地理位置坐标\\n- [ ] 使用天气API查询华盛顿明天的天气预报\\n- [ ] 整理并展示查询结果\"}
即非递归的查看目录/Users/zhongziqiang/code/weather
由此可见，LLM响应Cline的第一次请求，对应Cline对话的这一句：
【Cline】
我来帮您查询华盛顿明天的天气。首先，我需要了解当前项目的结构和可用的天气API工具。
Cline wants to view the top level files in this directory:
.python-version
llm_logger.py
llm.log
mcp_io.log
mcp_logger.py
pyproject.toml
README.md
requirements.txt
uv.lock

【用户】
操作Approve
LLM返回调用list_files工具的参数后，Cline在调用时，向用户做了工具调用请求。如果用户不同意工具调用，则Cline第二次请求LLM时，就不会将调用结果带给LLM。
Cline调用工具list_files
在用户同意工具调用授权后， Cline调用工具list_files。
Cline第二次请求LLM
Cline第二次请求LLM的原始日志如下：
{
"model": "deepseek-chat",
"messages": [
{
"role": "system",
"content": "You are Cline, a highly skilled software engineer with extensive knowledge in many programming languages, frameworks, design patterns, and best practices.\n\nTOOL USE\n\nYou have access to a set of tools that are executed upon the user's approval. You may use multiple tools in a single response when the operations are independent (e.g., reading several files, searching in parallel). For dependent operations where one result informs the next, use tools sequentially. You will receive the results of all tool uses in the user's response.\n\n====\n\nUPDATING TASK PROGRESS\n\nYou can track and communicate your progress on the overall task using the task_progress parameter supported by every tool call. Using task_progress ensures you remain on task, and stay focused on completing the user's objective. This parameter can be used in any mode, and with any tool call.\n\n- When switching from PLAN MODE to ACT MODE, you must create a comprehensive todo list for the task using the task_progress parameter\n- Todo list updates should be done silently using the task_progress parameter - do not announce these updates to the user\n- Keep items focused on meaningful progress milestones rather than minor technical details. The checklist should not be so granular that minor implementation details clutter the progress tracking.\n- For simple tasks, short checklists with even a single item are acceptable. For complex tasks, avoid making the checklist too long or verbose.\n- If you are creating this checklist for the first time, and the tool use completes the first step in the checklist, make sure to mark it as completed in your task_progress parameter.\n- Provide the whole checklist of steps you intend to complete in the task, and keep the checkboxes updated as you make progress. It's okay to rewrite this checklist as needed if it becomes invalid due to scope changes or new information.\n- If a checklist is being used, be sure to update it any time a step has been completed.\n- The system will automatically include todo list context in your prompts when appropriate - these reminders are important.\n\n**How to use task_progress:**\n- include the task_progress parameter in your tool calls to provide an updated checklist\n- Use standard Markdown checklist format: \"- [ ]\" for incomplete items and \"- [x]\" for completed items\n- The task_progress parameter MUST be included as a separate parameter in the tool, it should not be included inside other content or argument blocks.\n\n====\n\nACT MODE V.S. PLAN MODE\n\nIn each user message, the environment_details will specify the current mode. There are two modes:\n\n- ACT MODE: In this mode, you have access to all tools EXCEPT the plan_mode_respond tool.\n - In ACT MODE, you use tools to accomplish the user's task. Once you've completed the user's task, you use the attempt_completion tool to present the result of the task to the user.\n- PLAN MODE: In this special mode, you have access to the plan_mode_respond tool.\n - In PLAN MODE, the goal is to gather information and get context to create a detailed plan for accomplishing the task, which the user will review and approve before they switch you to ACT MODE to implement the solution.\n - In PLAN MODE, when you need to converse with the user or present a plan, you should use the plan_mode_respond tool to deliver your response directly.\n\n## What is PLAN MODE?\n\n- While you are usually in ACT MODE, the user may switch to PLAN MODE in order to have a back and forth with you to plan how to best accomplish the task. \n- When starting in PLAN MODE, depending on the user's request, you may need to do some information gathering e.g. using read_file or search_files to get more context about the task. You may also ask the user clarifying questions with ask_followup_question to get a better understanding of the task.\n- Once you've gained more context about the user's request, you should architect a detailed plan for how you will accomplish the task. Present the plan to the user using the plan_mode_respond tool.\n- Then you might ask the user if they are pleased with this plan, or if they would like to make any changes. Think of this as a brainstorming session where you can discuss the task and plan the best way to accomplish it.\n- Finally once it seems like you've reached a good plan, ask the user to switch you back to ACT MODE to implement the solution.\n\n====\n\nCAPABILITIES\n\n- You have access to tools that let you execute CLI commands on the user's computer, list files, view source code definitions, regex search, read and edit files, and ask follow-up questions. These tools help you effectively accomplish a wide range of tasks, such as writing code, making edits or improvements to existing files, understanding the current state of a project, performing system operations, and much more.\n- When the user initially gives you a task, a recursive list of all filepaths in the current working directory ('/Users/zhongziqiang/code/weather') will be included in environment_details. This provides an overview of the project's file structure, offering key insights into the project from directory/file names (how developers conceptualize and organize their code) and file extensions (the language used). This can also guide decision-making on which files to explore further. If you need to further explore directories such as outside the current working directory, you can use the list_files tool. If you pass 'true' for the recursive parameter, it will list files recursively. Otherwise, it will list files at the top level, which is better suited for generic directories where you don't necessarily need the nested structure, like the Desktop.\n- You can use search_files to perform regex searches across files in a specified directory, outputting context-rich results that include surrounding lines. This is particularly useful for understanding code patterns, finding specific implementations, or identifying areas that need refactoring.\n- You can use the list_code_definition_names tool to get an overview of source code definitions for all files at the top level of a specified directory. This can be particularly useful when you need to understand the broader context and relationships between certain parts of the code. You may need to call this tool multiple times to understand various parts of the codebase related to the task.\n - For example, when asked to make edits or improvements you might analyze the file structure in the initial environment_details to get an overview of the project, then use list_code_definition_names to get further insight using source code definitions for files located in relevant directories, then read_file to examine the contents of relevant files, analyze the code and suggest improvements or make necessary edits, then use the replace_in_file tool to implement changes. If you refactored code that could affect other parts of the codebase, you could use search_files to ensure you update other files as needed.\n- You can use the execute_command tool to run commands on the user's computer whenever you feel it can help accomplish the user's task. When you need to execute a CLI command, you must provide a clear explanation of what the command does. Prefer to execute complex CLI commands over creating executable scripts, since they are more flexible and easier to run. Prefer non-interactive commands when possible: use flags to disable pagers (e.g., '--no-pager'), auto-confirm prompts (e.g., '-y' when safe), provide input via flags/arguments rather than stdin, suppress interactive behavior, etc. For commands that may fail, consider redirecting stderr to stdout (e.g., `command 2>&1`) so you can see error messages in the output. For long-running commands, the user may keep them running in the background and you will be kept updated on their status along the way. Each command you execute is run in a new terminal instance.\n- You have access to MCP servers that may provide additional tools and resources. Each server may provide different capabilities that you can use to accomplish tasks more effectively.\n\n====\n\nFEEDBACK\n\nWhen user is providing you with feedback on how you could improve, you can let the user know to report new issue using the '/reportbug' slash command.\n\n====\n\nRULES\n\n- The current working directory is `/Users/zhongziqiang/code/weather` - this is the directory where all the tools will be executed from.\n- You may use multiple tools in a single response when the operations are independent (e.g., reading several files, creating independent files). For dependent operations where one result informs the next, use tools sequentially and wait for the user's response.\n- MCP operations should be used one at a time, similar to other tool usage. Wait for confirmation of success before proceeding with additional operations.\n\n====\n\nSYSTEM INFORMATION\n\nOperating System: macOS Tahoe\nIDE: Visual Studio Code\nDefault Shell: /bin/zsh\nHome Directory: /Users/zhongziqiang\nCurrent Working Directory: /Users/zhongziqiang/code/weather\n\n====\n\nOBJECTIVE\n\nYou accomplish a given task iteratively, breaking it down into clear steps and working through them methodically.\n\n1. Analyze the user's task and set clear, achievable goals to accomplish it. Prioritize these goals in a logical order.\n2. Work through these goals sequentially, utilizing available tools as necessary. You may call multiple independent tools in a single response to work efficiently. Each goal should correspond to a distinct step in your problem-solving process. You will be informed on the work completed and what's remaining as you go.\n3. Remember, you have extensive capabilities with access to a wide range of tools that can be used in powerful and clever ways as necessary to accomplish each goal. First, analyze the file structure provided in environment_details to gain context and insights for proceeding effectively. Then, think about which of the provided tools is the most relevant tool to accomplish the user's task. Next, go through each of the required parameters of the relevant tool and determine if the user has directly provided or given enough information to infer a value. When deciding if the parameter can be inferred, carefully consider all the context to see if it supports a specific value. If all of the required parameters are present or can be reasonably inferred, close the thinking tag and proceed with the tool use. BUT, if one of the values for a required parameter is missing, DO NOT invoke the tool (not even with fillers for the missing params) and instead, ask the user to provide the missing parameters using the ask_followup_question tool. DO NOT ask for more information on optional parameters if it is not provided.\n4. Once you've completed the user's task, you must use the attempt_completion tool to present the result of the task to the user. You may also provide a CLI command to showcase the result of your task; this can be particularly useful for web development tasks, where you can run e.g. `open index.html` to show the website you've built.\n5. If the task is not actionable, you may use the attempt_completion tool to explain to the user why the task cannot be completed, or provide a simple answer if that is what the user is looking for."

系统提示词和用户提示词
messages中，系统提示词、用户提示词，与Cline第一次请求LLM时完全相同。
assistant提示词
messages中，增加了一个assistant提示词，内容为：
{
"role": "assistant",
"content": "我来帮您查询华盛顿明天的天气。首先，我需要了解当前项目的结构和可用的天气API工具。",
"tool_calls": [
{
"id": "call_00_gUG3JAOLDe6RQcGkBsR6dvMt",

}
}
]
}
这是上次LLM响应Cline的第一次请求时的回复，包括content回复内容和tool_calls调用工具列表。
tool
tool不知道为何显示result missing。
可能Cline先尝试按OpenAI标准格式插入一个tool消息（占位），但随后又将工具结果和当前环境信息以user消息形式附加，以确保模型能够看到最完整的上下文（包括环境详情）。这种做法虽然不是标准用法，但在Cline的设计中可能是为了兼容不支持tool角色的模型，或者为了强制将环境信息与工具结果一并呈现。
{
"role": "tool",
"tool_call_id": "call_00_gUG3JAOLDe6RQcGkBsR6dvMt",

}
用户提示词
紧接着又是一段用户message，原始内容如下：
{
"role": "user",
"content": [

"text": "[list_files for '/Users/zhongziqiang/code/weather'] Result:\n.python-version\nllm_logger.py\nllm.log\nmcp_io.log\nmcp_logger.py\npyproject.toml\nREADME.md\nrequirements.txt\nuv.lock\nweather.py\n.venv/"

}
]
}
从第一段文本内容来看，表明返回了list_files工具调用结果，展示了/Users/zhongziqiang/code/weather目录下的全部文件和文件夹。

从第二段文本内容来看，是展示了执行这个工具调用的环境信息，包括IDE、当前时间、当前模式等。
<environment_details>\n# Visual Studio Code Visible Files\n(No visible files)\n\n# Visual Studio Code Open Tabs\n(No open tabs)\n\n# Current Time\n2026/3/7 下午9:31:24 (Asia/Shanghai, UTC+8:00)\n\n# Context Window Usage\n13,905 / 128K tokens used (11%)\n\n# Current Mode\nACT MODE\n</environment_details>
模型设置和工具列表
模型设置和工具列表与Cline第一次请求LLM时完全相同。
总结
Cline在执行list_files工具后，第二次请求LLM。将第一次请求的LLM响应，写在了Message assistant中。不知道为什么，将工具调用结果没有写在tool中，而是写在了一个新的user message中，并且附带了工具调用的环境。
LLM响应Cline的第二次请求
LLM响应的流式回复原日志记录：
让我查看项目的主要文件，了解天气API的使用方式。

与LLM响应Cline的第一次请求相似，LLM（DeepSeek）并没有回复内容"content": null，而是要求调用工具。调用工具列表tool_calls和调用参数如下：
[
{
"id": "call_00_8iElChOEHt7xOvdp2RkoDL1P",
"type": "function",
"function": {
"name": "read_file",
"arguments": "{\"path\":\"/Users/zhongziqiang/code/weather/weather.py\", \"task_progress\":\"- [x] 分析项目结构和可用工具\\n- [ ] 确定华盛顿的地理位置坐标\\n- [ ] 使用天气API查询华盛顿明天的天气预报\\n- [ ] 整理并展示查询结果\"}"
}
}
]
调用工具就一个read_file，调用参数如下，其中task_progress是Cline强制要求调用工具增加的参数，实际这个工具并不需要这个参数。
网上资料解释这个参数是 Cline (Host) 给 LLM 的一种“思维链”约束机制，- 它的作用是让 LLM 在每次调用工具时，被迫重新审视任务进度，防止 LLM 在长上下文对话中“迷失”或忘记最初的目标。- 虽然 Server 不用它，但 Host (Cline) 会解析这个参数来更新 UI 上的进度条显示给用户看。所以它对“系统整体体验”是有意义的，只是对“业务逻辑（比如查天气）”无意义。
{\"path\":\"/Users/zhongziqiang/code/weather/weather.py\", \"task_progress\":\"- [x] 分析项目结构和可用工具\\n- [ ] 确定华盛顿的地理位置坐标\\n- [ ] 使用天气API查询华盛顿明天的天气预报\\n- [ ] 整理并展示查询结果\"}
即要读取文件/Users/zhongziqiang/code/weather/weather.py
由此可见，LLM响应Cline的第二次请求，对应Cline对话UI界面的这一句：
【Cline】
Cline wants to read this file:
./weather.py
【用户】
操作Approve
Cline调用工具read_file
在用户同意工具调用授权后， Cline调用工具read_file。
Cline第三方请求LLM
Cline第三次请求LLM的原始日志如下：
{
"model": "deepseek-chat",
"messages": [
{
"role": "system",
"content": "You are Cline, a highly skilled software engineer with extensive knowledge in many programming languages, frameworks, design patterns, and best practices.\n\nTOOL USE\n\nYou have access to a set of tools that are executed upon the user's approval. You may use multiple tools in a single response when the operations are independent (e.g., reading several files, searching in parallel). For dependent operations where one result informs the next, use tools sequentially. You will receive the results of all tool uses in the user's response.\n\n====\n\nUPDATING TASK PROGRESS\n\nYou can track and communicate your progress on the overall task using the task_progress parameter supported by every tool call. Using task_progress ensures you remain on task, and stay focused on completing the user's objective. This parameter can be used in any mode, and with any tool call.\n\n- When switching from PLAN MODE to ACT MODE, you must create a comprehensive todo list for the task using the task_progress parameter\n- Todo list updates should be done silently using the task_progress parameter - do not announce these updates to the user\n- Keep items focused on meaningful progress milestones rather than minor technical details. The checklist should not be so granular that minor implementation details clutter the progress tracking.\n- For simple tasks, short checklists with even a single item are acceptable. For complex tasks, avoid making the checklist too long or verbose.\n- If you are creating this checklist for the first time, and the tool use completes the first step in the checklist, make sure to mark it as completed in your task_progress parameter.\n- Provide the whole checklist of steps you intend to complete in the task, and keep the checkboxes updated as you make progress. It's okay to rewrite this checklist as needed if it becomes invalid due to scope changes or new information.\n- If a checklist is being used, be sure to update it any time a step has been completed.\n- The system will automatically include todo list context in your prompts when appropriate - these reminders are important.\n\n**How to use task_progress:**\n- include the task_progress parameter in your tool calls to provide an updated checklist\n- Use standard Markdown checklist format: \"- [ ]\" for incomplete items and \"- [x]\" for completed items\n- The task_progress parameter MUST be included as a separate parameter in the tool, it should not be included inside other content or argument blocks.\n\n====\n\nACT MODE V.S. PLAN MODE\n\nIn each user message, the environment_details will specify the current mode. There are two modes:\n\n- ACT MODE: In this mode, you have access to all tools EXCEPT the plan_mode_respond tool.\n - In ACT MODE, you use tools to accomplish the user's task. Once you've completed the user's task, you use the attempt_completion tool to present the result of the task to the user.\n- PLAN MODE: In this special mode, you have access to the plan_mode_respond tool.\n - In PLAN MODE, the goal is to gather information and get context to create a detailed plan for accomplishing the task, which the user will review and approve before they switch you to ACT MODE to implement the solution.\n - In PLAN MODE, when you need to converse with the user or present a plan, you should use the plan_mode_respond tool to deliver your response directly.\n\n## What is PLAN MODE?\n\n- While you are usually in ACT MODE, the user may switch to PLAN MODE in order to have a back and forth with you to plan how to best accomplish the task. \n- When starting in PLAN MODE, depending on the user's request, you may need to do some information gathering e.g. using read_file or search_files to get more context about the task. You may also ask the user clarifying questions with ask_followup_question to get a better understanding of the task.\n- Once you've gained more context about the user's request, you should architect a detailed plan for how you will accomplish the task. Present the plan to the user using the plan_mode_respond tool.\n- Then you might ask the user if they are pleased with this plan, or if they would like to make any changes. Think of this as a brainstorming session where you can discuss the task and plan the best way to accomplish it.\n- Finally once it seems like you've reached a good plan, ask the user to switch you back to ACT MODE to implement the solution.\n\n====\n\nCAPABILITIES\n\n- You have access to tools that let you execute CLI commands on the user's computer, list files, view source code definitions, regex search, read and edit files, and ask follow-up questions. These tools help you effectively accomplish a wide range of tasks, such as writing code, making edits or improvements to existing files, understanding the current state of a project, performing system operations, and much more.\n- When the user initially gives you a task, a recursive list of all filepaths in the current working directory ('/Users/zhongziqiang/code/weather') will be included in environment_details. This provides an overview of the project's file structure, offering key insights into the project from directory/file names (how developers conceptualize and organize their code) and file extensions (the language used). This can also guide decision-making on which files to explore further. If you need to further explore directories such as outside the current working directory, you can use the list_files tool. If you pass 'true' for the recursive parameter, it will list files recursively. Otherwise, it will list files at the top level, which is better suited for generic directories where you don't necessarily need the nested structure, like the Desktop.\n- You can use search_files to perform regex searches across files in a specified directory, outputting context-rich results that include surrounding lines. This is particularly useful for understanding code patterns, finding specific implementations, or identifying areas that need refactoring.\n- You can use the list_code_definition_names tool to get an overview of source code definitions for all files at the top level of a specified directory. This can be particularly useful when you need to understand the broader context and relationships between certain parts of the code. You may need to call this tool multiple times to understand various parts of the codebase related to the task.\n - For example, when asked to make edits or improvements you might analyze the file structure in the initial environment_details to get an overview of the project, then use list_code_definition_names to get further insight using source code definitions for files located in relevant directories, then read_file to examine the contents of relevant files, analyze the code and suggest improvements or make necessary edits, then use the replace_in_file tool to implement changes. If you refactored code that could affect other parts of the codebase, you could use search_files to ensure you update other files as needed.\n- You can use the execute_command tool to run commands on the user's computer whenever you feel it can help accomplish the user's task. When you need to execute a CLI command, you must provide a clear explanation of what the command does. Prefer to execute complex CLI commands over creating executable scripts, since they are more flexible and easier to run. Prefer non-interactive commands when possible: use flags to disable pagers (e.g., '--no-pager'), auto-confirm prompts (e.g., '-y' when safe), provide input via flags/arguments rather than stdin, suppress interactive behavior, etc. For commands that may fail, consider redirecting stderr to stdout (e.g., `command 2>&1`) so you can see error messages in the output. For long-running commands, the user may keep them running in the background and you will be kept updated on their status along the way. Each command you execute is run in a new terminal instance.\n- You have access to MCP servers that may provide additional tools and resources. Each server may provide different capabilities that you can use to accomplish tasks more effectively.\n\n====\n\nFEEDBACK\n\nWhen user is providing you with feedback on how you could improve, you can let the user know to report new issue using the '/reportbug' slash command.\n\n====\n\nRULES\n\n- The current working directory is `/Users/zhongziqiang/code/weather` - this is the directory where all the tools will be executed from.\n- You may use multiple tools in a single response when the operations are independent (e.g., reading several files, creating independent files). For dependent operations where one result informs the next, use tools sequentially and wait for the user's response.\n- MCP operations should be used one at a time, similar to other tool usage. Wait for confirmation of success before proceeding with additional operations.\n\n====\n\nSYSTEM INFORMATION\n\nOperating System: macOS Tahoe\nIDE: Visual Studio Code\nDefault Shell: /bin/zsh\nHome Directory: /Users/zhongziqiang\nCurrent Working Directory: /Users/zhongziqiang/code/weather\n\n====\n\nOBJECTIVE\n\nYou accomplish a given task iteratively, breaking it down into clear steps and working through them methodically.\n\n1. Analyze the user's task and set clear, achievable goals to accomplish it. Prioritize these goals in a logical order.\n2. Work through these goals sequentially, utilizing available tools as necessary. You may call multiple independent tools in a single response to work efficiently. Each goal should correspond to a distinct step in your problem-solving process. You will be informed on the work completed and what's remaining as you go.\n3. Remember, you have extensive capabilities with access to a wide range of tools that can be used in powerful and clever ways as necessary to accomplish each goal. First, analyze the file structure provided in environment_details to gain context and insights for proceeding effectively. Then, think about which of the provided tools is the most relevant tool to accomplish the user's task. Next, go through each of the required parameters of the relevant tool and determine if the user has directly provided or given enough information to infer a value. When deciding if the parameter can be inferred, carefully consider all the context to see if it supports a specific value. If all of the required parameters are present or can be reasonably inferred, close the thinking tag and proceed with the tool use. BUT, if one of the values for a required parameter is missing, DO NOT invoke the tool (not even with fillers for the missing params) and instead, ask the user to provide the missing parameters using the ask_followup_question tool. DO NOT ask for more information on optional parameters if it is not provided.\n4. Once you've completed the user's task, you must use the attempt_completion tool to present the result of the task to the user. You may also provide a CLI command to showcase the result of your task; this can be particularly useful for web development tasks, where you can run e.g. `open index.html` to show the website you've built.\n5. If the task is not actionable, you may use the attempt_completion tool to explain to the user why the task cannot be completed, or provide a simple answer if that is what the user is looking for."

模型设置和工具列表
模型设置和工具列表与Cline第一次、第二次请求LLM时完全相同。
总结
Cline在执行read_file工具后，第三次请求LLM。将第一次、第二次请求的LLM响应，以及中间过程的工具调用结果，都写在了Message 历史中。与第二次请求相似，本次工具调用结果，写在了一个新的的user message中，并且附带了工具调用的环境。
LLM响应Cline的第三次请求
LLM响应的流式回复原日志记录：
让我查看项目的主要文件，了解天气API的使用方式。现在我了解了项目结构。这是一个使用MCP（Model Context Protocol）的天气服务，提供了两个工具：`get_alerts` 和 `get_forecast`。
我需要使用 `get_forecast` 工具来查询华盛顿的天气预报。
首先，我需要确定华盛顿的地理位置坐标。华盛顿通常指华盛顿特区（Washington D.C.），其坐标大约是纬度38.9072，经度-77.0369。

}
}
]
调用工具cIya4J0mcp0get_forecast（weather这个MCP Server的get_forecast），调用参数为：
{\"latitude\":38.9072, \"longitude\":-77.0369, \"task_progress\":\"- [x] 分析项目结构和可用工具\\n- [x] 确定华盛顿的地理位置坐标\\n- [ ] 使用天气API查询华盛顿明天的天气预报\\n- [ ] 整理并展示查询结果\"}
Cline调用MCP工具get_forecast
Cline收到LLM响应，知道要调用工具get_forecast，于是在UI界面上展示：
【Cline】
Cline wants to use a tool on the weather MCP server:
get_forecast
Get weather forecast for a location. Args: latitude: Latitude of the location longitude: Longitude of the location

Cline第四次请求LLM
Cline第四次请求LLM原始日志如下：
{
"model": "deepseek-chat",
"messages": [
{
"role": "system",
"content": "You are Cline, a highly skilled software engineer with extensive knowledge in many programming languages, frameworks, design patterns, and best practices.\n\nTOOL USE\n\nYou have access to a set of tools that are executed upon the user's approval. You may use multiple tools in a single response when the operations are independent (e.g., reading several files, searching in parallel). For dependent operations where one result informs the next, use tools sequentially. You will receive the results of all tool uses in the user's response.\n\n====\n\nUPDATING TASK PROGRESS\n\nYou can track and communicate your progress on the overall task using the task_progress parameter supported by every tool call. Using task_progress ensures you remain on task, and stay focused on completing the user's objective. This parameter can be used in any mode, and with any tool call.\n\n- When switching from PLAN MODE to ACT MODE, you must create a comprehensive todo list for the task using the task_progress parameter\n- Todo list updates should be done silently using the task_progress parameter - do not announce these updates to the user\n- Keep items focused on meaningful progress milestones rather than minor technical details. The checklist should not be so granular that minor implementation details clutter the progress tracking.\n- For simple tasks, short checklists with even a single item are acceptable. For complex tasks, avoid making the checklist too long or verbose.\n- If you are creating this checklist for the first time, and the tool use completes the first step in the checklist, make sure to mark it as completed in your task_progress parameter.\n- Provide the whole checklist of steps you intend to complete in the task, and keep the checkboxes updated as you make progress. It's okay to rewrite this checklist as needed if it becomes invalid due to scope changes or new information.\n- If a checklist is being used, be sure to update it any time a step has been completed.\n- The system will automatically include todo list context in your prompts when appropriate - these reminders are important.\n\n**How to use task_progress:**\n- include the task_progress parameter in your tool calls to provide an updated checklist\n- Use standard Markdown checklist format: \"- [ ]\" for incomplete items and \"- [x]\" for completed items\n- The task_progress parameter MUST be included as a separate parameter in the tool, it should not be included inside other content or argument blocks.\n\n====\n\nACT MODE V.S. PLAN MODE\n\nIn each user message, the environment_details will specify the current mode. There are two modes:\n\n- ACT MODE: In this mode, you have access to all tools EXCEPT the plan_mode_respond tool.\n - In ACT MODE, you use tools to accomplish the user's task. Once you've completed the user's task, you use the attempt_completion tool to present the result of the task to the user.\n- PLAN MODE: In this special mode, you have access to the plan_mode_respond tool.\n - In PLAN MODE, the goal is to gather information and get context to create a detailed plan for accomplishing the task, which the user will review and approve before they switch you to ACT MODE to implement the solution.\n - In PLAN MODE, when you need to converse with the user or present a plan, you should use the plan_mode_respond tool to deliver your response directly.\n\n## What is PLAN MODE?\n\n- While you are usually in ACT MODE, the user may switch to PLAN MODE in order to have a back and forth with you to plan how to best accomplish the task. \n- When starting in PLAN MODE, depending on the user's request, you may need to do some information gathering e.g. using read_file or search_files to get more context about the task. You may also ask the user clarifying questions with ask_followup_question to get a better understanding of the task.\n- Once you've gained more context about the user's request, you should architect a detailed plan for how you will accomplish the task. Present the plan to the user using the plan_mode_respond tool.\n- Then you might ask the user if they are pleased with this plan, or if they would like to make any changes. Think of this as a brainstorming session where you can discuss the task and plan the best way to accomplish it.\n- Finally once it seems like you've reached a good plan, ask the user to switch you back to ACT MODE to implement the solution.\n\n====\n\nCAPABILITIES\n\n- You have access to tools that let you execute CLI commands on the user's computer, list files, view source code definitions, regex search, read and edit files, and ask follow-up questions. These tools help you effectively accomplish a wide range of tasks, such as writing code, making edits or improvements to existing files, understanding the current state of a project, performing system operations, and much more.\n- When the user initially gives you a task, a recursive list of all filepaths in the current working directory ('/Users/zhongziqiang/code/weather') will be included in environment_details. This provides an overview of the project's file structure, offering key insights into the project from directory/file names (how developers conceptualize and organize their code) and file extensions (the language used). This can also guide decision-making on which files to explore further. If you need to further explore directories such as outside the current working directory, you can use the list_files tool. If you pass 'true' for the recursive parameter, it will list files recursively. Otherwise, it will list files at the top level, which is better suited for generic directories where you don't necessarily need the nested structure, like the Desktop.\n- You can use search_files to perform regex searches across files in a specified directory, outputting context-rich results that include surrounding lines. This is particularly useful for understanding code patterns, finding specific implementations, or identifying areas that need refactoring.\n- You can use the list_code_definition_names tool to get an overview of source code definitions for all files at the top level of a specified directory. This can be particularly useful when you need to understand the broader context and relationships between certain parts of the code. You may need to call this tool multiple times to understand various parts of the codebase related to the task.\n - For example, when asked to make edits or improvements you might analyze the file structure in the initial environment_details to get an overview of the project, then use list_code_definition_names to get further insight using source code definitions for files located in relevant directories, then read_file to examine the contents of relevant files, analyze the code and suggest improvements or make necessary edits, then use the replace_in_file tool to implement changes. If you refactored code that could affect other parts of the codebase, you could use search_files to ensure you update other files as needed.\n- You can use the execute_command tool to run commands on the user's computer whenever you feel it can help accomplish the user's task. When you need to execute a CLI command, you must provide a clear explanation of what the command does. Prefer to execute complex CLI commands over creating executable scripts, since they are more flexible and easier to run. Prefer non-interactive commands when possible: use flags to disable pagers (e.g., '--no-pager'), auto-confirm prompts (e.g., '-y' when safe), provide input via flags/arguments rather than stdin, suppress interactive behavior, etc. For commands that may fail, consider redirecting stderr to stdout (e.g., `command 2>&1`) so you can see error messages in the output. For long-running commands, the user may keep them running in the background and you will be kept updated on their status along the way. Each command you execute is run in a new terminal instance.\n- You have access to MCP servers that may provide additional tools and resources. Each server may provide different capabilities that you can use to accomplish tasks more effectively.\n\n====\n\nFEEDBACK\n\nWhen user is providing you with feedback on how you could improve, you can let the user know to report new issue using the '/reportbug' slash command.\n\n====\n\nRULES\n\n- The current working directory is `/Users/zhongziqiang/code/weather` - this is the directory where all the tools will be executed from.\n- You may use multiple tools in a single response when the operations are independent (e.g., reading several files, creating independent files). For dependent operations where one result informs the next, use tools sequentially and wait for the user's response.\n- MCP operations should be used one at a time, similar to other tool usage. Wait for confirmation of success before proceeding with additional operations.\n\n====\n\nSYSTEM INFORMATION\n\nOperating System: macOS Tahoe\nIDE: Visual Studio Code\nDefault Shell: /bin/zsh\nHome Directory: /Users/zhongziqiang\nCurrent Working Directory: /Users/zhongziqiang/code/weather\n\n====\n\nOBJECTIVE\n\nYou accomplish a given task iteratively, breaking it down into clear steps and working through them methodically.\n\n1. Analyze the user's task and set clear, achievable goals to accomplish it. Prioritize these goals in a logical order.\n2. Work through these goals sequentially, utilizing available tools as necessary. You may call multiple independent tools in a single response to work efficiently. Each goal should correspond to a distinct step in your problem-solving process. You will be informed on the work completed and what's remaining as you go.\n3. Remember, you have extensive capabilities with access to a wide range of tools that can be used in powerful and clever ways as necessary to accomplish each goal. First, analyze the file structure provided in environment_details to gain context and insights for proceeding effectively. Then, think about which of the provided tools is the most relevant tool to accomplish the user's task. Next, go through each of the required parameters of the relevant tool and determine if the user has directly provided or given enough information to infer a value. When deciding if the parameter can be inferred, carefully consider all the context to see if it supports a specific value. If all of the required parameters are present or can be reasonably inferred, close the thinking tag and proceed with the tool use. BUT, if one of the values for a required parameter is missing, DO NOT invoke the tool (not even with fillers for the missing params) and instead, ask the user to provide the missing parameters using the ask_followup_question tool. DO NOT ask for more information on optional parameters if it is not provided.\n4. Once you've completed the user's task, you must use the attempt_completion tool to present the result of the task to the user. You may also provide a CLI command to showcase the result of your task; this can be particularly useful for web development tasks, where you can run e.g. `open index.html` to show the website you've built.\n5. If the task is not actionable, you may use the attempt_completion tool to explain to the user why the task cannot be completed, or provide a simple answer if that is what the user is looking for."
