微信公众号二维码

Overview

根据微信公众号 ID 生成关注二维码链接，并在用户没有提供 ID 时，用内置引导图帮助用户在微信中找到公众号 ID。

二维码规则：

https://open.weixin.qq.com/qr/code?username={公众号ID}

Workflow

1. If the user provides a公众号 ID, normalize it and generate the QR code URL directly.
2. If the user provides a full QR URL, extract the username value and regenerate the canonical URL.
3. If the user does not provide an ID, show the three guide images from assets/ and ask them to follow the steps to copy the ID.
4. In Agent/Codex chat surfaces, download the QR image to a local file and embed it with an absolute local path. Do not rely on the remote WeChat image URL for Markdown preview.
5. Return the公众号 ID, the canonical URL, and the local image preview.

Generate QR Code

Use the helper script for deterministic output. Prefer downloading to ~/Downloads/wechat-qrcodes/ so Agent surfaces can render the image from a local absolute path:

python3 <skill_dir>/scripts/generate_qr.py gh_11eec77a7c51 \
  --download \
  --output ~/Downloads/wechat-qrcodes/gh_11eec77a7c51.jpg

Example output:

公众号ID：gh_11eec77a7c51
二维码链接：https://open.weixin.qq.com/qr/code?username=gh_11eec77a7c51
本地图片：/Users/example/Downloads/wechat-qrcodes/gh_11eec77a7c51.jpg

![微信公众号二维码](/Users/example/Downloads/wechat-qrcodes/gh_11eec77a7c51.jpg)

If the user only wants the URL and does not need an image preview, omit --download:

python3 <skill_dir>/scripts/generate_qr.py gh_11eec77a7c51

Help User Find The ID

When the user does not know the公众号 ID, provide these steps and include the matching images:

1. Open the chat with the公众号, tap the profile icon in the upper-right corner.
   • Image: assets/step-1-open-profile.jpg
2. Tap the公众号 name on the profile page.
   • Image: assets/step-2-tap-name.jpg
3. In the basic information panel, copy the value shown next to 微信号; this is the公众号 ID.
