+# GitHub OpenGraph 插件
+
+## 功能说明
+自动识别群聊/私聊中的 `github.com` 链接，将其转换为 GitHub OpenGraph 预览图并发送图片消息。
+
+## 触发规则
+1. `fuzzy` 模式：消息中只要包含 GitHub 链接就会触发。
+2. `exact` 模式：消息内容必须是完整 GitHub 链接才会触发。
+
+## 权限控制
+插件注册了群功能开关：
+- `FEATURE_KEY`: `GITHUB_OPENGRAPH`
+- `FEATURE_DESCRIPTION`: `🧩 GitHub链接卡片 [自动转OpenGraph图片]`
+
+如果某群关闭该功能，该群消息不会触发处理。
+
+## 配置项
+见 [config.toml](/D:/learn/abot/plugins/github_opengraph/config.toml)：
+- `enable`：总开关
+- `match_mode`：匹配模式（`fuzzy` / `exact`）
+- `max_links_per_message`：单条消息最大处理链接数
+- `hash_salt`：OpenGraph 哈希盐值
+- `request_timeout_seconds`：拉图超时秒数
+
+## 典型示例
+原链接：
+`https://github.com/python/cpython/issues/12345`
+
+转换后：
+`https://opengraph.githubassets.com/<hash>/python/cpython/issues/12345`
