auth-wechat-miniprogram

A guide for handling native user identity in WeChat Mini Programs connected to CloudBase, Tencent’s cloud development platform. It covers identities such as OPENID and UNIONID and how wx.cloud authentication behaves.

In plain words
What is it for?
Use it when building or debugging mini program login, user identity checks, or cloud-function code that needs to know who called it.
Why use it?
It removes uncertainty about how a mini program identifies users without treating it like a normal website login. It helps avoid using the wrong login or token flow.

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-wechat-miniprogram 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 today.

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 — 131 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

  • The task is about WeChat Mini Program auth behavior, wx.cloud identity, OPENID / UNIONID, or how a mini program caller is identified in CloudBase.
  • The project is a CloudBase mini program and the auth question is about native mini program identity rather than provider configuration.

Read before writing code if

  • The request mentions mini program login, user identity in cloud functions, or wx.cloud auth assumptions.
  • The user expects a Web-style login page or explicit token exchange in a mini program; route them back to native mini program auth behavior.

Then also read

  • Mini program project implementation -> ../miniprogram-development/SKILL.md
  • Cloud function implementation -> ../cloud-functions/SKILL.md

Do NOT use for

  • Web-based WeChat login or Web auth UI.
  • Provider enable/disable or auth console setup.
  • Generic Node-side auth flows outside mini program identity handling.

Common mistakes / gotchas

  • Generating a Web-style login page for a wx.cloud mini program.
  • Treating mini program auth as a provider-configuration problem.
  • Forgetting that caller identity is injected in cloud functions automatically.

When to use this skill

Use this skill for WeChat Mini Program (小程序) authentication in a CloudBase project.

Use it when you need to:

  • Implement identity-aware WeChat Mini Program flows with CloudBase
  • Access user identity (openid, unionid) in cloud functions
  • Understand how WeChat authentication integrates with CloudBase
  • Build Mini Program features that require user identification

Key advantage: WeChat Mini Program authentication with CloudBase is seamless and automatic - no complex OAuth flows needed. When a Mini Program calls a cloud function, the user's openid is automatically injected and verified by WeChat.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
