 `+init` 是推荐便捷入口；想逐步手动控制时，先 `+git-credential-init` 拿 `repository_url`，再用原生 `git clone` / `git checkout sprint/default`。
 
+**`+init` 完成后必须执行**：`cat <project-path>/.agents/skills/plugin-guide/SKILL.md`，读取仓库插件指引。该文件包含插件目录、实例配置规则和调用代码生成方式——不读就无法正确集成插件能力。文件不存在则跳过。

+安装插件包到项目。运行时命令事实以 `lark-cli apps +plugin-install --help` 为准。
+
+## 何时用
+
+用户要接入 AI 能力或飞书平台能力，需要先安装对应的插件包。安装后才能创建插件实例。具体有哪些可用插件、该选哪个，读取创建的应用仓库 Skill：`.agents/skills/plugin-guide/SKILL.md`。
+
+**插件包 ≠ npm 包**：插件包写入 `actionPlugins`，npm 写入 `dependencies`，两套独立机制。禁止用 `npm install` 代替本命令。
+
+## 命令骨架
+
+- `--name <key>`：插件包 key（从仓库 Skill 的「AI 插件目录」获取）。不传则批量安装 `actionPlugins` 中声明的所有插件。
+- `--version <ver>`：指定版本（如 `1.0.0`）。不传则安装最新版。
+
+在项目根目录下运行（和 npm 一样，无需指定路径）。
+
+## 示例
+
+```bash
+# 安装最新版
+lark-cli apps +plugin-install --name <plugin-key>
+
+# 安装指定版本
+lark-cli apps +plugin-install --name <plugin-key> --version 1.0.0
+
+# 批量安装已声明的所有插件
+lark-cli apps +plugin-install
+```
+
+## 输出契约
+
+- 已安装同版本会跳过（status=already_installed）。
+- 失败时 hint 指示原因（网络/版本不存在/package.json 缺失）。
