-# Hello Plugin
-
-这是给 AstrBot SDK 插件作者准备的最小示例。
-
-## 目录结构
-
-```text
-hello_plugin/
-├── plugin.yaml
-├── requirements.txt
-├── main.py
-└── tests
-    └── test_plugin.py
-```
-
-## 能学到什么
-
-- 如何定义一个 `Star` 插件
-- 如何注册命令 handler
-- 如何使用 `MessageEvent.reply()`
-- 如何用 `PluginHarness.from_plugin_dir()` 走真实 dispatch 链
-- 如何从 `Context` 里读取当前插件元数据
-- 如何用 `MockContext` / `MockMessageEvent` 写插件测试
-
-## 运行
-
-在仓库根目录执行：
-
-```bash
-cd examples/hello_plugin
-astrbot-sdk validate
-astrbot-sdk dev --local --event-text hello
-astrbot-sdk dev --local --watch --event-text hello
-```
-
-## 测试
-
-```bash
-python -m pytest examples/hello_plugin/tests/test_plugin.py -v
-```
-
-## 代码说明
-
-- `hello`: 最小命令，收到 `hello` 时回复 `Hello, World!`
-- `about`: 读取 `ctx.metadata.get_current_plugin()`，演示 capability 客户端的基础用法
-- `tests/test_plugin.py`: 展示 direct handler test
-- `tests/test_dispatch.py`: 展示 `PluginHarness.from_plugin_dir()` dispatch test
