Claude Code 系统提示词和 11个内置 Tool拆解

Claude Code 是 Anthropic 开发的一个人工智能代码助手工具，它作为命令行界面 (CLI) 工具直接在你的终端中运行。它被设计为帮助开发人员更快速地编写代码、解决问题和理解代码库。

Claude Code目前是闭源的，而且使用的话需要单独收费另外充值 Token，因为成本太高，而且封号严重，不太建议直接上手。

为了获取它的系统提示词，本次同样使用了Go起了一个转发后台服务，将原本请求Claude的 API代理到了DeepSeek。

请求转发示意图：

下面是对Claude Code系统提示词和11个功能工具tools参数解析。

API 请求内容结构

{   "model": "deepseek-ai/DeepSeek-V3",   "messages": [     {       "content": "You are Claude Code, Anthropic's official CLI for Claude...",       "role": "system"     },     {       "content": "1",       "role": "user"     },     {       "content": [         {           "text": "API Error: 400 OpenAI API error: {"code":20015,"message":"max_tokens: Must be less than or equal to 4096","data":null}n",           "type": "text"         }       ],       "role": "assistant"     },     {       "content": "<bash-input>cd /tmp</bash-input>",       "role": "user"     },     {       "content": [         {           "text": "<bash-stdout>Changed directory to u001b[1m/tmp/u001b[22m</bash-stdout>",           "type": "text"         }       ],       "role": "assistant"     },     {       "content": "ls",       "role": "user"     },     {       "content": [         {           "text": "API Error: 400 OpenAI API error: {"code":20015,"message":"max_tokens: Must be less than or equal to 4096","data":null}n",           "type": "text"         }       ],       "role": "assistant"     },     {       "content": [         {           "text": "ls",           "type": "text"         }       ],       "role": "user"     }   ],   "max_tokens": 16384,   "temperature": 1,   "stream": true,   "tools": [     // 这里是工具数组，包含各种工具的定义   ] }

工具数组(tools)定义了模型可以使用的11个功能工具。以下是对每个工具的详细解析：

1. dispatch_agent

{   "function": {     "description": "Launch a new agent that has access to the following tools: View, GlobTool, GrepTool, LS, ReadNotebook. When you are searching for a keyword or file and are not confident that you will find the right match in the first few tries, use the Agent tool to perform the search for you...",     "name": "dispatch_agent",     "parameters": {       "$schema": "http://json-schema.org/draft-07/schema#",       "additionalProperties": false,       "properties": {         "prompt": {           "description": "The task for the agent to perform",           "type": "string"         }       },       "required": ["prompt"],       "type": "object"     }   },   "type": "function" }

功能: 启动新的代理进程，该代理可以访问View、GlobTool、GrepTool、LS和ReadNotebook工具
适用场景: 搜索关键词或文件，特别是在不确定能否快速找到匹配时
参数:

prompt(必需): 字符串，描述代理需要执行的任务

使用注意:

可以并行启动多个代理以提高性能
代理完成后会返回一条消息，该消息对用户不可见
代理调用是无状态的，不能发送额外消息
代理不能使用Bash、Replace、Edit、NotebookEditCell等修改文件的工具

2. Bash

{   "function": {     "description": "Executes a given bash command in a persistent shell session with optional timeout, ensuring proper handling and security measures...",     "name": "Bash",     "parameters": {       "$schema": "http://json-schema.org/draft-07/schema#",       "additionalProperties": false,       "properties": {         "command": {           "description": "The command to execute",           "type": "string"         },         "timeout": {           "description": "Optional timeout in milliseconds (max 600000)",           "type": "number"         }       },       "required": ["command"],       "type": "object"     }   },   "type": "function" }

功能: 在持久化的shell会话中执行bash命令
参数:

command(必需): 要执行的命令
timeout(可选): 超时时间(毫秒)，最大600000ms(10分钟)

使用规则:

创建文件前先验证目录路径
禁止使用特定命令(alias, curl, wget等)
避免使用搜索命令如find和grep，使用专用工具代替
避免使用cat、head、tail、ls等，使用View和LS工具代替
命令共享同一个shell会话，环境变量等状态会持续
提供详细的git提交和PR创建流程指导

3. BatchTool
