+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+IC Coder Plugin 是一个 VS Code 扩展，为 Verilog/FPGA 开发提供智能辅助功能，包括代码生成、文件操作、iverilog 仿真和 VCD 波形查看。
+
+## Build Commands
+
+```bash
+# 安装依赖
+pnpm install
+
+# 编译 (开发模式)
+pnpm run compile
+
+# 监听模式编译
+pnpm run watch
+
+# 生产环境打包
+pnpm run package
+
+# 代码检查
+pnpm run lint
+
+# 运行测试
+pnpm run test
+
+# 编译测试文件
+pnpm run compile-tests
+```
+
+## Development
+
+- 按 F5 在 VS Code 中启动调试模式
+- 使用 webpack 打包，入口文件为 `src/extension.ts`
+- 输出目录为 `dist/`
+
+## Architecture
+
+```

+├── types/
+│   └── chatHistory.ts    # 消息类型定义 (LangChain4j 格式)
+└── test/                 # 测试文件
+```
+
+### Key Components
+
+**消息流程**: Webview -> `onDidReceiveMessage` -> `messageHandler.ts` -> 后端处理 -> `panel.webview.postMessage` -> Webview
+
+**消息类型** (`src/types/chatHistory.ts`):
+- `MessageType.SYSTEM` / `USER` / `AI` / `TOOL_EXECUTION_RESULT`
+- 兼容 LangChain4j 格式
+
+**iverilog 集成** (`tools/iverilog/`):
+- 内置 Windows x64 版本的 iverilog/vvp
+- 通过 `IVERILOG_ROOT` 环境变量配置库路径
+- 支持命令: "生成 VCD"、"运行仿真"、"生成波形"
+
+## VS Code Extension Points
+
+- 命令: `ic-coder.openPanel`, `ic-coder.openChat`, `ic-coder.openVCDViewer`
+- 侧边栏视图: `ic-coder.mainView`
+- 激活事件: `onLanguage:verilog`, `onLanguage:vhdl`, `onStartupFinished`
+
+## Dependencies
+
+- `vcdrom`, `vcd-stream`, `waveql` - VCD 波形处理
+- `@wavedrom/doppler`, `onml` - 波形渲染
+- `iconv-lite` - 编码转换
+
+## Notes
+
+- `webviewContent.ts` 和 `messageHandler.ts` 文件较大，建议使用搜索而非完整读取
+- 当前仅支持 Windows 平台的 iverilog，其他平台需用户自行安装
