auth-nodejs-cloudbase

A guide for handling CloudBase user identity in Node.js backend code.

In plain words
What is it for?
Use it to identify the caller, look up users, issue custom login tickets, or connect an existing user system to CloudBase.
Why use it?
It separates server-side identity work from login-provider setup and browser login screens.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

auth-nodejs-cloudbase scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 446 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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
