v1: 模型即代理

~200 行代码，4 个工具，所有编程 Agent 的本质。

Claude Code 的秘密？没有秘密。

剥去 CLI 外观、进度条、权限系统，剩下的出奇简单：一个让模型持续调用工具直到任务完成的循环。

核心洞察

传统助手：

1	用户 -> 模型 -> 文本回复

Agent 系统：

1 2	用户 -> 模型 -> [工具 -> 结果]* -> 回复 ^_________\|

星号很重要。模型反复调用工具，直到它决定任务完成。这将聊天机器人转变为自主代理。

核心洞察：模型是决策者，代码只提供工具并运行循环。

四个核心工具

Claude Code 有约 20 个工具，但 4 个覆盖 90% 的场景：

工具	用途	示例
`bash`	运行命令	`npm install`, `git status`
`read_file`	读取内容	查看 `src/index.ts`
`write_file`	创建/覆盖	创建 `README.md`
`edit_file`	精确修改	替换一个函数

有了这 4 个工具，模型可以：

探索代码库（bash: find, grep, ls）
理解代码（read_file）
做出修改（write_file, edit_file）
运行任何东西（bash: python, npm, make）

Agent 循环

整个 Agent 在一个函数里：

def agent_loop(messages):
    while True:
        # 1. 询问模型
        response = client.messages.create(
            model=MODEL, system=SYSTEM,
            messages=messages, tools=TOOLS
        )

        # 2. 打印文本输出
        for block in response.content:
            if hasattr(block, "text"):
                print(block.text)

        # 3. 如果没有工具调用，完成
        if response.stop_reason != "tool_use":
            return messages

        # 4. 执行工具，继续循环
        results = []
        for tc in response.tool_calls:
            output = execute_tool(tc.name, tc.input)
            results.append({"type": "tool_result", "tool_use_id": tc.id, "content": output})

        messages.append({"role": "assistant", "content": response.content})
        messages.append({"role": "user", "content": results})

为什么这能工作：

模型控制循环（持续调用工具直到 stop_reason != "tool_use"）
结果成为上下文（作为 “user” 消息反馈）
记忆自动累积（messages 列表保存历史）

系统提示词

唯一需要的”配置”：

SYSTEM = f"""You are a coding agent at {WORKDIR}.

Loop: think briefly -> use tools -> report results.

Rules:
- Prefer tools over prose. Act, don't just explain.
- Never invent file paths. Use ls/find first if unsure.
- Make minimal changes. Don't over-engineer.
- After finishing, summarize what changed."""

没有复杂逻辑，只有清晰的指令。

为什么这个设计有效

1. 简单
没有状态机，没有规划模块，没有框架。

2. 模型负责思考
模型决定用哪些工具、什么顺序、何时停止。

3. 透明
每个工具调用可见，每个结果在对话中。

4. 可扩展
添加工具 = 一个函数 + 一个 JSON schema。

缺少什么

特性	为什么省略	添加于
待办追踪	非必需	v2
子代理	复杂度	v3
权限	学习目的信任模型	生产版

关键点：核心是微小的，其他都是精化。

更大的图景

Claude Code、Cursor Agent、Codex CLI、Devin——都共享这个模式：

while not done:
    response = model(conversation, tools)
    results = execute(response.tool_calls)
    conversation.append(results)

差异在于工具、显示、安全性。但本质始终是：给模型工具，让它工作。

模型即代理。这就是全部秘密。

v1_basic_agent.py - Mini Claude Code: Model as Agent (~200 lines)

Core Philosophy: "The Model IS the Agent"
=========================================
The secret of Claude Code, Cursor Agent, Codex CLI? There is no secret.

Strip away the CLI polish, progress bars, permission systems. What remains
is surprisingly simple: a LOOP that lets the model call tools until done.

Traditional Assistant:
    User -> Model -> Text Response

Agent System:
    User -> Model -> [Tool -> Result]* -> Response
                          ^________|

The asterisk (*) matters! The model calls tools REPEATEDLY until it decides
the task is complete. This transforms a chatbot into an autonomous agent.

KEY INSIGHT: The model is the decision-maker. Code just provides tools and
runs the loop. The model decides:
  - Which tools to call
  - In what order
  - When to stop

The Four Essential Tools:
------------------------
Claude Code has ~20 tools. But these 4 cover 90% of use cases:

    | Tool       | Purpose              | Example                    |
    |------------|----------------------|----------------------------|
    | bash       | Run any command      | npm install, git status    |
    | read_file  | Read file contents   | View src/index.ts          |
    | write_file | Create/overwrite     | Create README.md           |
    | edit_file  | Surgical changes     | Replace a function         |

With just these 4 tools, the model can:
  - Explore codebases (bash: find, grep, ls)
  - Understand code (read_file)
  - Make changes (write_file, edit_file)
  - Run anything (bash: python, npm, make)
