## What it does

This skill guides coding agents through backend authentication workflows using `@cloudbase/node-sdk`. It targets cloud functions and standalone Node.js runtimes that must inspect caller identity via `auth.getUserInfo()`, returning `uid`, `openId`, and `customUserId` for authorization checks.

The instructions include canonical patterns for querying user records with `getEndUserInfo` or `queryUserInfo`. It also details how to bridge external authentication systems into CloudBase by issuing custom login tokens with `auth.createTicket()`. Network audits rely on `auth.getClientIP()`.

You need a CloudBase environment ID to initialize the SDK. This skill strictly excludes frontend login UI and provider administration, so keep client SDK tasks in separate modules.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add TencentCloudBase/skills --skill auth-nodejs-cloudbase -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/auth-nodejs-cloudbase/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/auth-nodejs-cloudbase/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add TencentCloudBase/skills --skill auth-nodejs-cloudbase -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/auth-nodejs-cloudbase/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add TencentCloudBase/skills --skill auth-nodejs-cloudbase -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/auth-nodejs-cloudbase/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install TencentCloudBase/skills auth-nodejs-cloudbase
```

2. **Manually: put the files in place**
- File: `.github/skills/auth-nodejs-cloudbase/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add TencentCloudBase/skills --skill auth-nodejs-cloudbase -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/TencentCloudBase/skills --path skills/auth-nodejs-cloudbase
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/auth-nodejs-cloudbase/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add TencentCloudBase/skills --skill auth-nodejs-cloudbase -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/TencentCloudBase/skills/tree/HEAD/skills/auth-nodejs-cloudbase/SKILL.md

## When to use it
- Extract caller identity and UID inside a CloudBase cloud function
- Bridge external user databases into CloudBase using custom login tickets
- Look up user profiles by UID, email, or phone number using the Node SDK
- Capture client IP addresses for backend security audits

## Example prompts
- Show how to initialize @cloudbase/node-sdk and read the caller UID in a cloud function
- Create a custom login ticket with auth.createTicket for an external user id
- Find a CloudBase user profile using queryUserInfo by phone number

description: CloudBase Node SDK auth guide for server-side identity, user lookup, and custom login tickets. This skill should be used when Node.js code must read caller identity, inspect end users, or bridge an existing user system into CloudBase; not when configuring providers or building client login UI.

## Sibling skills (local only)

Sibling CloudBase skills ship beside this skill. Use local relative paths such as `../auth-tool-cloudbase/SKILL.md`.

If a referenced sibling skill file is missing from this environment, ask the user to install the full CloudBase plugin (or the missing skill). Do **not** HTTP-fetch remote skill or protocol markdown into the agent context.

## Activation Contract

### Use this first when

- Node.js code in cloud functions or backend services must read caller identity, look up users, or issue custom login tickets.
- The backend responsibility is auth / identity, not provider setup or frontend login UI.

### Read before writing code if

- The task mentions `@cloudbase/node-sdk`, server-side auth, custom login tickets, or "who is calling".
- The request mixes frontend login with backend identity logic; split the flow and route client-side work elsewhere.

### Then also read

- Provider setup / publishable key -> `../auth-tool-cloudbase/SKILL.md`
- Web login UI that consumes custom tickets -> `../auth-web-cloudbase/SKILL.md`
- Raw HTTP auth client -> `../http-api-cloudbase/SKILL.md`

### Do NOT use for

- Provider enable/disable or login console configuration.
- Frontend login / sign-up UI.
- Mini program native auth.

### Common mistakes / gotchas

- Using this skill as the entry point for every auth request.
- Mixing provider-management work with Node-side identity code.
- Reaching for raw HTTP examples when Node SDK already covers the job.

## When to use this skill

Use this skill whenever the task involves **server-side authentication or identity** in a CloudBase project, and the code is running in **Node.js**, for example:

- CloudBase 云函数 (Node runtime) that needs to know **who is calling**
- Node services that use **CloudBase Node SDK** to look up user information
- Backends that issue **custom login tickets** for Web / mobile clients
- Admin or ops tools that need to inspect CloudBase end-user profiles

**Do NOT use this skill for:**

- Frontend Web login / sign-up flows using `@cloudbase/js-sdk` (handle those with the **auth-web** skill, not this Node skill).
- Direct HTTP auth API integrations (this skill does not describe raw HTTP endpoints; use the **http-api** skill instead).
- Database or storage operations that do not involve identity (use database/storage docs or skills).
