# Tencent Agent Storage (云文件上传备份工具)
将本地文件上传至 Tencent Agent Storage,自动生成下载链接和图片预览。上传的文件存储在用户独有的云盘空间中,支持跨端访问——无论是手机、电脑还是平板,用户都可以随时随地查看和下载自己的文件。
## When to Use
Agent **MUST** activate this skill when any of the following conditions are met:
- User mentions cloud drive keywords: 网盘、云盘、云空间、龙虾盘、专属网盘、cloud drive, my drive
- User requests file listing or browsing: 列出文件、有哪些文件、list files, show files
- User requests upload or backup: 上传文件、备份到云、存到网盘、upload, backup, save to cloud
- User asks to send/deliver files: 把文件发给我、发到手机、send file, deliver file
- User requests links or sharing: 生成下载链接、分享文件、download link, share link
- User queries file status: 这个云文件还在吗、链接过期了、is file still there
- User requests file search: 搜索文件、找文件、检索文件、搜索云盘、search files, find file
- **Implicit**: A task produces output files that need to be delivered to the user, or the user's intent implies needing a file on another device
## Quick Reference
| Command | Usage | Description |
|---------|-------|-------------|
| `upload` | `node scripts/agent-storage.js upload '<json>'` | Upload local file to cloud, returns download link |
| `uploadDir` | `node scripts/agent-storage.js uploadDir '<json>'` | Upload entire folder to cloud, preserving directory structure |
| `info` | `node scripts/agent-storage.js info '<json>'` | Get file info and regenerate download link |
| `list` | `node scripts/agent-storage.js list '<json>'` | List files in a cloud directory |
| `search` | `node scripts/agent-storage.js search '<json>'` | Search files by name |
| `mkdir` | `node scripts/agent-storage.js mkdir '<json>'` | Create a directory in cloud storage |
## Setup
### Prerequisites
此 skill 需要 **Node.js ≥ 14** 和 **npm**。Agent 在首次执行前**必须检测运行环境**:
```bash
node --version # 期望输出 v14.x 或更高
npm --version
```
如果 `node` 命令不存在或版本低于 14,直接安装:
根据用户系统自动选择安装方式:
```bash
# macOS (Homebrew)
brew install node
# macOS (无 Homebrew)
curl -o node.pkg "https://nodejs.org/dist/v20.18.0/node-v20.18.0.pkg" && sudo installer -pkg node.pkg -target / && rm node.pkg
# Linux (Debian/Ubuntu)
curl -fsSL https://deb.nodesource.com/setup_lts.x | sudo -E bash - && sudo apt-get install -y nodejs
# Linux (其他发行版 / 通用)
curl -fsSL https://nodejs.org/dist/v20.18.0/node-v20.18.0-linux-x64.tar.xz | sudo tar -xJ -C /usr/local --strip-components=1
# Windows (PowerShell, 管理员)
winget install OpenJS.NodeJS.LTS
# Windows (无 winget)
# 下载安装包: https://nodejs.org/dist/v20.18.0/node-v20.18.0-x64.msi 并运行
# 跨平台 (已有 nvm)
nvm install --lts
```
此 skill 还依赖 `smh-node-sdk` npm 包(**要求 ^1.0.8**)。**必须在使用前完成安装**(二选一):
```bash
# 方式一:全局安装(推荐)
npm install -g smh-node-sdk@^1.0.8
# 方式二:本地安装到项目目录
npm install smh-node-sdk@^1.0.8
```
> 脚本会按以下顺序查找 SDK:当前项目 node_modules → 全局 node_modules。如果未找到,脚本会报错并提示安装命令。
### About the upload script
此 skill 的运行脚本位于 `scripts/agent-storage.js`。Agent 直接通过 `node scripts/agent-storage.js <command> '<json>'` 调用,**无需额外写入临时文件**。脚本源码可在 `scripts/` 目录中审阅。
### Credential configuration
凭证从以下配置文件中自动加载(优先级从高到低)。
> **安全说明**:脚本仅读取配置文件中 `smh_` 前缀的环境变量(`smh_libraryId`、`smh_accessToken` 等),不会访问配置文件中的其他字段或敏感信息。
> **关于 token 权限**:Tencent Agent Storage 的文件上传和下载链接生成 API 要求 `space_admin` 级别的 accessToken,这是 Tencent Agent Storage 服务端对文件写入操作的最低权限要求。
**模式一:直接凭证(accessToken)**
凭证文件查找顺序(先找到者优先):
1. **通用配置** — `~/.tencentAgentStorage/.env`
2. **OpenClaw** — `~/.openclaw/openclaw.json` 的 `env` 字段
3. **Hermes** — `~/.hermes/.env`
**通用配置(推荐)** — 在 `~/.tencentAgentStorage/.env` 中配置:
```env
# ~/.tencentAgentStorage/.env
smh_basePath=https://api.tencentsmh.cn
smh_libraryId=smhxxx-xxxxx
smh_spaceId=space-xxxxx
smh_accessToken=<your-access-token>
```
**OpenClaw** — 在 `~/.openclaw/openclaw.json` 的 `env` 字段中配置:
```json
{
"env": {
"smh_basePath": "https://api.tencentsmh.cn",
"smh_libraryId": "smhxxx-xxxxx",
"smh_spaceId": "space-xxxxx",
"smh_accessToken": "<your-access-token>"
}
}
```
**Hermes** — 在 `~/.hermes/.env` 中配置:
```env
smh_basePath=https://api.tencentsmh.cn
smh_libraryId=smhxxx-xxxxx
smh_spaceId=space-xxxxx
smh_accessToken=<your-access-token>
```
---
## Procedure
Agent uses this skill in any scenario that requires uploading files to the cloud.
### Complete flow
```
User triggers file upload
→ Step 1: Identify the local file path(s)
→ Step 2: Run upload script (loop for batch)
→ Step 3: Extract downloadUrl from JSON output (signed COS URL)
→ Step 4: Deliver the download link with execution notice
```
> **IMPORTANT**: 默认使用 `conflictStrategy: "rename"` 上传。当云端已存在同名文件时,脚本会自动重命名(如 `file(1).pdf`),确保上传始终成功并返回正确的下载链接。**只有用户明确说了 "覆盖"/"替换" 时,才使用 `conflictStrategy: "overwrite"`;用户明确要求先确认时,才使用 `conflictStrategy: "ask"`。**
### Step 2: Upload
**Single file (默认):**
```bash
node scripts/agent-storage.js upload '{"localPath":"/path/to/file.pdf","conflictStrategy":"rename"}'
```
**Upload to specific directory:**
```bash
node scripts/agent-storage.js upload '{"localPath":"/path/to/photo.jpg","remotePath":"photos/photo.jpg","conflictStrategy":"rename"}'
```
**User explicitly requested overwrite:**
```bash
node scripts/agent-storage.js upload '{"localPath":"/path/to/report.pdf","conflictStrategy":"overwrite"}'
```
**Batch upload:**
```bash
node scripts/agent-storage.js upload '{"localPath":"/path/to/file1.pdf","conflictStrategy":"rename"}'
node scripts/agent-storage.js upload '{"localPath":"/path/to/file2.docx","conflictStrategy":"rename"}'
```
#### Conflict handling
When using `conflictStrategy: "rename"` (默认), if a same-name file already exists, the script automatically renames the file (e.g. `file(1).pdf`) and completes the upload, ensuring a valid download link is always returned.
When using `conflictStrategy: "ask"`, if a same-name file already exists, the script returns `{"success":false,"conflict":true}`. Agent must then ask the user:
> 云端已存在同名文件 `{filename}`,你想怎么处理?
>
> 1. 🔄 覆盖 — 替换云端文件
> 2. 📝 重命名 — 自动改名上传(如 file(1).pdf)
> 3. ❌ 取消 — 不上传
**三种策略对照:**
| Strategy | Behavior | When to use |
|----------|----------|-------------|
| `rename` (**默认**) | 同名文件存在时自动重命名,确保上传成功并返回正确链接 | 大多数场景,需要保证用户拿到下载链接 |
| `overwrite` | 直接覆盖已有文件 | 用户明确说 "覆盖", "替换", "更新文件" |
| `ask` | 同名文件存在时返回错误,Agent 询问用户 | 用户明确要求先确认时 |
### Step 4: Deliver link + execution notice
After every successful upload, include this notice alongside the download link(s):
> 链接已生成,链接有效期 2 小时,可直接在浏览器或手机中打开。
**链接输出规则(MUST):**
1. **必须使用带 COS 签名的直链**(`downloadUrl` 字段),域名为 `*.tencentsmhuc.cn`,参数含 `q-sign-algorithm` 和 `q-signature`
2. **禁止输出含 `accessToken` 的中转链接**(如 `https://api.tencentsmh.cn/...?access_token=...`),这会泄露凭证
3. **链接必须完整输出,禁止任何形式的截断、省略或缩写**——不能用 `...`、`<省略>` 等替代任何部分。签名链接通常很长,这是正常的
**Single file example:**
> 链接已生成,链接有效期 2 小时,可直接在浏览器或手机中打开。
>
> 已上传文件: report.pdf 大小: (2.3 MB)
> 下载链接: {脚本返回的完整 downloadUrl,原样输出,不得截断}
**Batch example:**
> 链接已生成,链接有效期 2 小时,可直接在浏览器或手机中打开。
>
> 📎 report.pdf (2.3 MB) — {完整 downloadUrl}
> 📎 photo.jpg (1.1 MB) — {完整 downloadUrl}

## File Size Support
**There is NO file size limit.** The upload script supports files of any size, including multi-GB videos.
- **Small files (≤ 50 MB)**: Single-part upload.
- **Large files (> 50 MB)**: Multipart upload — the file is read in 5 MB chunks, never loaded entirely into memory.
---

## Pitfalls
### Error handling
所有命令输出 JSON 到 stdout。错误也以 JSON 返回:`{"success": false, "error": "..."}`
| 错误 | 处理方式 |
|------|---------|
| 上传失败(`success: false`) | 告诉用户:"文件上传失败:{具体原因}。你可以稍后再试,或者检查网络连接。" |
| 同名冲突(`conflict: true`) | 询问用户选择覆盖、重命名或取消 |
| 文件不存在 | 让用户确认路径 |
| 网络错误 | 重试 2 次,间隔 3s;仍失败告知用户 |
| 配置缺失 | 提示用户在 `~/.tencentAgentStorage/.env`、`~/.openclaw/openclaw.json` 的 `env` 字段或 `~/.hermes/.env` 中添加 `smh_*` 配置 |
**上传失败对话模板**(当 `success: false` 时必须使用):
> ❌ 文件上传失败:{error 中的具体原因}。
>
> 你可以:
> 1. 🔄 重试 — 重新上传这个文件
> 2. ❌ 取消 — 暂时不上传
### Prohibited actions
- **NEVER** 在 `success: false` 时展示下载链接
- **NEVER** 在上传失败时不告知用户,必须明确提示"文件上传失败"及原因
- **NEVER** 硬编码或暴露 SMH 凭证给用户
- **NEVER** 未经用户主动要求就上传其本地个人文件
- **NEVER** 跳过执行通知:"链接已生成,有效期 2 小时,可直接在浏览器或手机中打开"
- **NEVER** 在用户未明确要求覆盖时使用 `conflictStrategy: "overwrite"`
- **NEVER** 把含 `accessToken` 的中转链接(如 `https://api.tencentsmh.cn/...?access_token=...`)发给用户。返回给用户的**必须是带 COS 签名的直链**(域名为 `*.tencentsmhuc.cn`,参数含 `q-sign-algorithm` 和 `q-signature`),即脚本输出的 `downloadUrl` 字段
- **NEVER** 截断、省略或用 `...` 缩写链接。发给用户的下载链接/预览链接**必须是脚本返回的完整 URL**,一个字符都不能少。链接通常很长(含签名参数),这是正常的,**必须原样完整输出**
### Common mistakes
- 用户说"上传文件"但没指定路径 → 追问:"你要上传哪个文件?告诉我文件路径或文件名就行。"
- 用户说"确定上传 xxx"或"把 xxx 发给我" → 直接执行上传(`conflictStrategy: "rename"`)
- **同名文件冲突**:默认使用 `conflictStrategy: "rename"`,自动重命名保证上传成功。只有用户明确要求覆盖时才用 `overwrite`,用户明确要求先确认时才用 `ask`
- 文件默认上传到云空间根目录,用户可通过 `remotePath` 参数指定目标路径
- 下载链接为通过 SDK `infoFile({ purpose: 'download' })` 获取的带签名 COS 直链(`https://bucket-xxxxx.tencentsmhuc.cn/...?q-sign-algorithm=sha1&q-signature=...`),可直接在浏览器或手机中打开预览/下载,**有效期约 2 小时**。**必须原样完整输出此链接,禁止截断或省略任何部分**
- 批量上传按顺序处理(不并行),避免 API 过载
- **执行通知**:每次上传完成后必须告知用户:"链接已生成,有效期 2 小时,可直接在浏览器或手机中打开"
---
## Verification
Upload was successful when ALL of the following are true:
1. Script output contains `"success": true`
2. `downloadUrl` field is present and non-empty
3. Agent delivered the download link to the user with the execution notice: "链接已生成,有效期 2 小时,可直接在浏览器或手机中打开"
To verify a previously uploaded file still exists:
```bash
node scripts/agent-storage.js info '{"remotePath":"<filename>"}'
```
If the response contains `"success": true`, the file is accessible and a fresh download link is returned.
