Mini Claude Code - 极简教学版 AI 编程助手
Project description
MiniCC
极简版 Claude Code,用于教学。
想知道 Claude Code 这类 AI 编程助手是怎么实现的? 看这个项目就够了。核心代码约 1400 行,架构清晰,注释充分。
能干嘛
- 读写文件、搜索代码、执行 shell 命令
- 创建子任务并行处理
- 终端 UI 界面,支持流式输出
技术栈
- pydantic-ai - Agent 框架
- Textual - TUI 框架
快速开始
# 设置 API Key
export ANTHROPIC_API_KEY="your-key"
# 或 export OPENAI_API_KEY="your-key"
# 直接运行(无需安装)
uvx minicc
# 或者安装后运行
uv pip install minicc
minicc
开发
git clone https://github.com/TokenRollAI/miniCC.git
cd miniCC
uv sync
uv run minicc
项目结构
minicc/
├── cli.py # 入口(仅启动 TUI)
├── core/ # 运行时/模型/事件总线/MCP 预加载
├── tools/ # 工具实现(按职责拆分)
└── tui/ # Textual TUI(消费 stream events)
配置
配置文件在 ~/.minicc/config.json:
{
"provider": "anthropic",
"model": "claude-sonnet-4-20250514"
}
可选 MCP 配置:
- 项目级:
<project>/.minicc/mcp.json - 全局:
~/.minicc/mcp.json
MiniCC 会自动加载 MCP servers,并把它们的工具注册给 Agent。
如需启用 MCP(连接/启动 MCP servers),请安装可选依赖:pip install "minicc[mcp]"。
Prompt Cache (Anthropic)
按照 pydantic-ai Anthropic 指南 可以在配置里开启 prompt caching:
{
"provider": "anthropic",
"model": "claude-sonnet-4-20250514",
"prompt_cache": {
"instructions": true,
"tool_definitions": "1h",
"messages": true
}
}
instructions缓存系统提示词;tool_definitions缓存工具定义;messages缓存最近一条用户消息true表示 5 分钟 TTL,或显式写"5m"/"1h"- Anthropic 最多支持 4 个 cache points,pydantic-ai 会按指南自动裁剪超出的 CachePoint
工具列表
