+| 指标 | 数值 |
+|------|------|
+| 代码规模 | **7K LOC** |
+| 模块数 | **71 modules** |
+| 测试数 | **44 tests** |
+| 内置工具 | **30+ built-in tools** |
+
+**为什么选择 LangCode：**
+
+- **对标 Claude Code 工程水准** — 六层架构（Layer 0–5），层间依赖严格单向，零循环引用
+- **纯 tool calling 路由** — 无脆弱的文本解析，LLM 输出结构化 tool_calls 直接驱动分发
+- **代码修改后强制验证** — auto_verify 不靠提示词"请检查"，而是图节点强制跑 compile/import/lint/test
+- **AST 语义级编辑** — 基于 tree-sitter 的重命名、加参数、加方法，比纯文本替换更安全
+- **生产级错误恢复** — 截断升级、prompt 压缩、模型 fallback、断路器，长会话不崩溃
+- **内存安全** — PythonTool 有内存看门狗，BashTool 有命令分类器，路径沙箱锁定工作目录
