 # 阿里云百炼CLI 安装说明（供 AI Agent 阅读）
 
-本文档面向 **AI Agent**：按下列步骤为用户安装并校验 **阿里云百炼CLI**（npm 包名 `bailian-cli`，命令 `bl` / `bailian`）。用户通常通过 **npm 全局安装** 使用，**无需**访问本仓库源码。不要臆造版本号或路径；以用户环境为准。
+本文档面向 **AI Agent**：按下列步骤为用户安装并校验 **阿里云百炼CLI**（命令 `bl` / `bailian`）。**优先**使用二进制一键安装（无需 Node）；若环境已有 Node / 需要 Command Pack，再用 npm。不要臆造版本号或路径；以用户环境为准。
 
-## 1. 安装前检查
+## 1. 推荐：二进制安装（无需 Node）
 
-**原则**：先执行检查；若 **Node / 包管理器 / 网络** 任一不满足下文要求，Agent 应 **在本机终端内主动完成安装或配置**（例如升级 Node、切换镜像、配置 `npm` 代理等），再继续 `bailian-cli` 安装。仅在无权限或环境无法自动化时，再向用户说明原因并请其配合。
+```bash
+curl -fsSL https://bailian-cli.oss-cn-hangzhou.aliyuncs.com/bailian-cli/install.sh | bash
+```
 
-1. **Node.js**
-   - 要求 **≥ 18.17.0**，执行 `node -v` 确认。
-   - 未安装或版本不足：由 Agent 自行安装或升级 Node。
+Windows PowerShell：
 
-2. **npm**（**唯一**允许的包管理器）
-   - 执行 `npm -v` 确认可用。
-   - 未安装或不可用：由 Agent **安装或修复 npm**（不要改用 pnpm/yarn 装 `bailian-cli`），再执行 `npm install -g bailian-cli`。
-   - 即使本机已安装 `pnpm`、`yarn` 等，**也仅用于其它项目**；装 `bailian-cli` 时仍必须用 `npm`。
+```powershell
+irm https://bailian-cli.oss-cn-hangzhou.aliyuncs.com/bailian-cli/install.ps1 | iex
+```
 
-3. **网络**
-   - 需能访问 npm registry（默认 **registry.npmjs.org**）。
-   - 不可达：由 Agent 自行配置镜像或代理后重试。
+校验：
 
----
+```bash
+bl --version
+which bl   # Windows: where.exe bl
+```
 
-## 2. 安装 CLI 与 Skills
+若 `command not found`：把 `~/.local/bin`（Windows 为 `%LOCALAPPDATA%\bailian-cli\bin`）加入 PATH 后开新终端。
 
-**仅允许以下命令**（不要用 `pnpm add -g`、`yarn global add` 等）。按顺序执行，上一步通过后再进行下一步。
+> CDN / GitHub Release 未就绪或下载失败时，回退到下方 npm 安装。
 
-**2.1 安装 CLI**
+## 2. 备选：npm 安装（需要 Node.js >= 18.17）
+
+1. `node -v` 确认版本。
+2. `npm -v` 确认可用（**仅允许 npm** 全局安装，不要用 pnpm/yarn）。
+3. 执行：
 
 ```bash
 npm install -g bailian-cli
 ```
 
-安装成功后，应能在 PATH 中找到：
+4. 校验：`bl --version`。
 
-- `bl`（短别名）
-- `bailian`（全名）
-
-**校验**（Agent 应执行并检查退出码与输出）：
-
-```bash
-bl --version
-which bl   # Windows 可用 where bl
-```
-
-若 `command not found`：检查全局 bin 是否在 PATH（`npm config get prefix`，其下 `bin` 目录应加入 PATH）。
-
-**2.2 安装 Skills**
-
-CLI 校验通过后，在本机终端执行：
+可选 skills（与 CLI 本体无关，按需）：
 
 ```bash
 npx skills add modelstudioai/cli --all -g
 ```
 
-安装成功后，用中文简要说明已安装的 skills 及用户可做什么。
-
----
-
 ## 3. 鉴权（安装后必做才能调 API）
 
 ### 推荐：浏览器登录（控制台会话）
 
-适用于本机交互式安装，无需用户手动复制 API Key：
-
 1. 执行 `bl auth status --output json`，判断是否已配置。
-2. 若未配置，在**用户本机终端**执行 `bl auth login --console`；命令会拉起浏览器完成阿里云控制台登录授权。
+2. 若未配置，在**用户本机终端**执行 `bl auth login --console`。
 3. 登录成功后执行 `bl auth status --output json` 确认；汇报时只使用 masked 字段，**禁止**回显完整凭据。
 
-> 此方式同时打通 `app list`、`usage free` 等控制台能力，并自动配置 API Key 调用所需的鉴权信息。
+### 备选：API Key / Token Plan
 
-### 备选一：由 Agent 引导用户输入普通 API Key 后登录
-
-适用于无法拉起浏览器的对话式安装（远程 SSH、CI 调试、纯终端环境等）：
-
-- 获取入口：[百炼控制台 API Key](https://bailian.console.aliyun.com/cn-beijing/?tab=app#/api-key)
-
-1. 执行 `bl auth status --output json`，判断是否已配置。
-2. 若未配置或后续 API 校验失败，**请用户粘贴 API Key**（可说明从上述控制台复制；勿要求用户发到公开渠道）。
-3. 用户提供了 Key 之后，在**用户本机终端**执行（Agent 用终端工具跑，勿把 Key 写进回复正文）：`bl auth login --api-key <用户提供的_Key>`
-4. 登录成功后执行 `bl auth status --output json` 确认；汇报时只使用 masked 字段，**禁止**回显完整 Key。
-
-### 备选二：使用 Token Plan API Key
-
-- 获取入口：[Token Plan 订阅详情](https://bailian.console.aliyun.com/cn-beijing?tab=plan#/efm/subscription/overview)
-
-1. 请用户从订阅详情页获取或复制 Token Plan API Key，勿要求用户发到公开渠道。
-2. 在用户本机终端执行：`bl auth login --config token-plan --api-key <用户提供的_Key>`。
-3. `token-plan` Profile 已内置默认 Base URL；登录命令会先测试 Key，通过后才保存并激活该 Profile，无需另行配置或重复测试。
-4. 执行 `bl auth status --config token-plan --output json` 确认；汇报时只使用 masked 字段。
-
-### 其他方式
-
-- **环境变量**（不落盘到配置文件）：在 shell 中配置 API Key 环境变量；变量名见 `bl auth status --help`，勿在对话中向用户解释底层命名。
-- **写入配置文件**（持久化，与 `auth login` 落盘相同）：`bl config set --key api_key --value <key>`（`--key api-key` 亦可）。**不会**像 `bl auth login --api-key` 那样先校验 Key 是否可用；Agent 引导安装时仍**优先**用 `auth login`。
-- **命令行临时传入**：需要 API Key 的 `bl` 子命令可在**当次**执行附加全局 `--api-key <key>`，仅本次生效、不落盘（例：`bl text chat --api-key sk-xxx --message "你好"`）。与上文持久化方式不是同一用途。
+- 普通 Key：`bl auth login --api-key <Key>`
+- Token Plan：`bl auth login --config token-plan --api-key <Key>`
 
 ### Agent 安全约束
 
 - **禁止**把真实 API Key 写入仓库、日志、Skill、聊天记录的可公开部分。
-- CI / 非交互环境：使用 `bl ... --non-interactive`；通过密钥管理或环境变量注入，勿在脚本中硬编码 Key。
-
----
+- CI / 非交互环境：使用 `bl ... --non-interactive`；通过密钥管理或环境变量注入。
 
 ## 4. 配置验证
 
-API Key 登录命令本身已经完成可用性测试，通过后只需确认配置状态：
-
 ```bash
 bl auth status --output json
 ```
 
-无需再执行重复的模型调用测试。若登录失败，根据 stderr / JSON 中的 `hint` 或 `message` 排查（网络、Key 无效、`base_url` 等）。DashScope 端点：使用 `--base-url` / `bl config set --key base_url` / `DASHSCOPE_BASE_URL`，默认中国大陆 `https://dashscope.aliyuncs.com`。

+  └─ GitHub Release（source of truth）
+        ↓

+        ↓
+  别处维护的 install.sh / install.ps1 → 只拉 OSS
+```
+
+| 环节                      | 谁负责       | 本仓库是否实现                  |
+| ------------------------- | ------------ | ------------------------------- |
+| npm publish               | 本仓库 CI    | ✅                              |

+| Release → OSS 同步        | **外部 FC**  | ❌（仅可选 webhook 触发）       |
+| 生产安装脚本              | **别处维护** | ❌（`packaging/` 仅作契约参考） |
+| 用户 curl / irm           | OSS 上的脚本 | ❌                              |
+
+本仓库**不存放、不上传 OSS AccessKey**；开源侧只用 `GITHUB_TOKEN`。
+
+---
+
+## 2. 本仓库发版（Publish）
+
+入口：`.github/workflows/publish.yml` → `publish-stable.mjs` / `publish-channel.mjs`。
+
+```text
+stable:
+  check → npm latest → git tag v<ver> → gh release（正式）
+  assets: bl-*, SHA256SUMS, latest.json
+  （不再把 install.sh/ps1 挂到 Release；生产脚本外置）
+
+channel:
+  bump beta → npm @channel → gh prerelease v<beta>
+  + 滚动 prerelease tag channel-<name>（仅 <name>.json）
+```
+
+可选：发版成功后 `POST` `BAILIAN_OSS_SYNC_WEBHOOK`，通知 FC 开始同步（Secret 配置，无则跳过）。
+
+`--skip-binary`：只发 npm。
+
+### 构建矩阵

+| `bun-windows-x64`  | `windows-x64.exe` |
+
+不构建 `linux-arm64` / `windows-arm64`。
+
+---
+
+## 3. GitHub Release 约定（source of truth）
+
+基址：`https://github.com/modelstudioai/cli/releases`
+
+| 模式           | Tag                                            | 资产                                    |
+| -------------- | ---------------------------------------------- | --------------------------------------- |
+| stable         | `v<version>`（先 push tag，再 `--verify-tag`） | 矩阵二进制、`SHA256SUMS`、`latest.json` |
+| channel 版本化 | `v0.0.0-beta-<sha7>-<date>`（prerelease）      | 二进制、`SHA256SUMS`                    |
+| channel 滚动   | `channel-<name>`（prerelease，clobber）        | `<name>.json`                           |
+
+Manifest 内 `url` 指向 GitHub download（给 FC / 镜像方解析用）。FC 同步到 OSS 时应**改写**为 OSS URL，或安装脚本忽略 `url`、按固定 OSS 路径拼接。
+
+---
+
+## 4. 外部 FC（本仓库不实现）
+
+建议契约：
+
+1. 触发：Publish webhook，或监听 `release` 事件 / 定时拉取 Latest
+2. 读取 GitHub Latest（stable）或约定 channel tag
+3. 下载资产 → 上传 OSS，建议布局：
+
+```text
+https://bailian-cli.oss-cn-hangzhou.aliyuncs.com/bailian-cli/
+  channels/latest.json          # 改写 url 后的正式版 manifest
+  channels/<channel>.json       # 可选测试渠道
+  releases/<version>/
+    bl-<version>-<os>-<arch>[.exe]
+    SHA256SUMS
+  install.sh                    # 由脚本维护方上传，非本仓库 CI
+  install.ps1
+```
+
+4. **完整校验后再对外**：SHA256 对齐、矩阵文件齐全，避免「Release 已发、OSS 半同步」窗口误导用户
+5. 失败告警（钉钉/飞书/SLS），因用户安装不经过本仓库 CI
+
+---
+
+## 5. 安装脚本（别处维护）
+
+生产入口（示例，以实际 OSS 域名为准）：
+
+```bash
+curl -fsSL https://bailian-cli.oss-cn-hangzhou.aliyuncs.com/bailian-cli/install.sh | bash
+# Windows:
+irm https://bailian-cli.oss-cn-hangzhou.aliyuncs.com/bailian-cli/install.ps1 | iex
+```
+
+脚本只依赖 OSS；不要求用户访问 GitHub。
+
+本仓 `packaging/install.sh` / `install.ps1`：**契约参考**（路径、校验、`install-method=binary`），不作为生产分发物挂 Release。
+
+### 与本仓的契约（脚本方必须遵守）
+
+- 资产名：`bl-<ver>-<os>-<arch>[.exe]`
+- 校验：`SHA256SUMS`
+- 渠道：默认 `latest`；可选 `BAILIAN_CHANNEL`
+- 写入：`~/.bailian/install-method` = `binary`
+- 不支持：linux-arm64 / windows-arm64 → 提示 `npm i -g bailian-cli`
+
+---
+
+## 6. 运行时（本仓库）
+
+- `BAILIAN_COMPILED=1`、install-method、`bl update` 分流仍在本仓
+- 二进制更新默认读 **OSS** manifest（`BAILIAN_CLI_CDN` 可覆盖）；与用户安装源一致
+- GitHub Release 仍是发版真相源；更新链路走 OSS 镜像
+
+---
+
+## 7. 职责边界（验收标准）
+
+| 验收项            | 通过条件                                              |
+| ----------------- | ----------------------------------------------------- |
+| 本仓库 Publish 绿 | npm 可装 + GitHub Release 资产齐全                    |
+| 国内可一键安装    | FC 已同步 + 外置脚本可 curl（**不在本仓 CI 门禁内**） |
+| 无 AK 进 git      | OSS 密钥只在 FC / 脚本发布流水线                      |
+
+---
+
+## 8. 风险
+
+- Release 成功 ≠ 用户能装（依赖 FC）→ 必须有同步监控
+- 脚本外置 → 命名/矩阵变更要同步通知脚本方
+- `latest.json` 双份（GH / OSS）→ FC 负责改写与一致性
+- channel 是否进 OSS：由 FC 与脚本方另定；本仓照常发 prerelease
+
+---
