+# C++ 代理规则集
+
+本规则集定义 AI/自动化代理在处理 C++ 代码时必须遵守的核心约束。
+
+## 范围与优先级
+
+- 作为仓库级基线规则集使用；更靠近代码目录的规则更具体并可覆盖基线。
+- 当代理规则与 docs 冲突：安全/合规优先，其次保持仓库一致性。
+
+## 代理工作原则（铁律）
+
+1. 先理解目标与上下文，再动手改代码
+2. 修改要小而清晰；避免无关重构
+3. 发现安全问题（内存安全/鉴权漏洞）立即标注或修复
+4. 不引入新依赖或工具，除非明确要求
+
+## C++ 核心约定（不可违反）
+
+- 语言标准：C++23；优先使用 Modules；避免裸指针、`new/delete`、C 风格字符串
+- 代码风格：Google C++ Style Guide；使用项目 `.clang-format`；头文件保护用 `#pragma once`
+- 命名规范：文件 `lower_with_under.cpp/.h/.cppm`；类型 `CapWords`；函数/变量 `lower_with_under`；常量 `kCapWords`；成员 `lower_with_under_`；命名空间 `lower_with_under`
+- Modules 工程：模块名点分层 `lower_snake_case`；接口文件 `.cppm`；修改 `export module` 必须更新 CMake module file-set
+- 构建与依赖：Conan 需提供 `conan-release`/`conan-debug`；`conan install` + `cmake --preset ...`；Windows 通过 Linux + Clang 交叉编译验证
+
+## 安全红线（不可触碰）
+
+- 不得在代码/日志/注释中写入明文密钥、密码、Token、API Key
+- 避免内存不安全操作：悬垂指针、双重释放、越界访问
+- 禁用不安全函数（`strcpy`, `sprintf`, `gets` 等）
+- 修改鉴权/权限逻辑必须说明动机与风险
+
+## 权威来源
+
+- 代码风格：`docs/cpp/code_style.md`
+- 命名规范：`docs/cpp/naming.md`
+- 工具链：`docs/cpp/toolchain.md`
+- 依赖管理：`docs/cpp/dependencies_conan.md`
+- clangd 配置：`docs/cpp/clangd.md`
+
+## Skills（按需加载）
+
+- `$commit-message`
+
+## 与开发规范的关系
+
+- 本仓库内：`docs/cpp/` 与 `docs/common/`
+- 目标项目 subtree：`docs/standards/playbook/docs/cpp/` 与 `docs/standards/playbook/docs/common/`
