# ai-model-wechat

A skill for calling AI models in WeChat Mini Programs through wx.cloud.extend.AI. Useful when you add text generation to a mini app and don't want to guess the call shapes.

## What it does

The skill covers `wx.cloud.extend.AI` inside WeChat Mini Programs: `generateText` and `streamText` with the `onText`, `onEvent` and `onFinish` callbacks. The streaming call wraps its payload in `data`; the plain one returns the raw response. You pick a model with `wx.cloud.extend.AI.createModel` and put the model id in the `model` field inside `data`.

The trap is the `createModel` argument. It is a group name, not a vendor and not a model id. Only three values are legal: `hunyuan-exp` for the Mini Program growth plan, `cloudbase` for the main managed pool, and `custom-<your-name>` for a group you onboarded yourself. Writing `createModel("deepseek")` or passing a model-id variable is the usual mistake, and the skill blocks it.

Before any business code, the skill insists on a two-step preflight: billing eligibility first, group readiness second. If a model is not already in the managed catalog, you enable it with `UpdateAIModel`. This is not for browser or Web apps, not for a Node.js backend, and not for image generation — sibling CloudBase skills handle those.

## Install

1. **Skills CLI (Vercel)**
```bash
npx skills add TencentCloudBase/skills --skill ai-model-wechat -a claude-code
```

2. **Manually: put the files in place**

## When to use it
- call an AI model from a WeChat Mini Program
- stream a model response into the mini app UI
- wire up a Hunyuan model in the WeChat environment
- figure out what to pass to `createModel`
- enable a model in the managed group

## Example prompts
- Add text generation to my WeChat Mini Program using wx.cloud.extend.AI
- Set up streaming with the onText callback in my mini app
- Connect hunyuan-2.0-instruct-20251111 to my Mini Program

## 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.

## When to use this skill

Use this skill for **calling AI models in WeChat Mini Program** using `wx.cloud.extend.AI`.

**Use it when you need to:**

- Integrate AI text generation in a Mini Program
- Stream AI responses with callback support
- Call Hunyuan models from the WeChat environment

**Do NOT use for:**

- Browser/Web apps → use `ai-model-web` skill
- Node.js backend or cloud functions → use `ai-model-nodejs` skill
- Image generation → use `ai-model-nodejs` skill (not available in Mini Program)
- Runtimes without a CloudBase SDK (native apps, Python, etc.) → use `http-api-cloudbase` skill (it now includes the `ai_model` OpenAPI spec for direct HTTP calls)

## ⛔ STOP — `wx.cloud.extend.AI.createModel(provider)` argument is **not** a vendor / model name

Read this before writing any `createModel(...)` line. Agents frequently hallucinate this argument. There are **exactly three** legal shapes. Anything else is a bug.

| ✅ Legal `createModel(provider)` argument | When to use it |
|-----------------------------------------|----------------|
| `"hunyuan-exp"` | The Mini Program **成长计划** (`ai_miniprogram_inspire_plan`) is enrolled for the current env. Default model: `hunyuan-2.0-instruct-20251111`. |
| `"cloudbase"` | Default fallback. Main managed group (TokenHub-backed, multi-vendor pool). Vendor + concrete model go into the **`model` field**, e.g. `{ model: "deepseek-v4-flash" }`. |
