agent-from-scratch
从零手写一个 AI Agent 的教学型 Python 项目：不依赖任何智能体框架实现核心循环，用约 3700 行可通读的代码，把 Agent 拆成乐高积木式的基础部件——模型调用、工具协议、执行上下文、记忆、RAG、Skills、E2B 沙箱与多智能体编排，逐层拼装、每一步都能追到源码。附 20 个可运行示例、21 章系统课程与 30 篇分层文档，配有单元与集成测试、mypy 严格类型检查。学操作系统要写迷你 OS，学数据库要写迷你数据库，学 Agent 就该亲手写一个：先建知识底座，再上生产框架。适合初学者、大学生与用过框架想补原理的工程师。MIT 开源，Python 3.13。

Same idea, different domain
Nobody's really built a dev tools tool for Sales yet.
