WeChat Article Publisher

Publish Markdown or HTML content to WeChat Official Account drafts via API, with automatic format conversion.

Prerequisites

• WECHAT_API_KEY environment variable set (from .env file)

• Python 3.9+

• Authorized WeChat Official Account on wx.limyai.com

Scripts

Located in ~/.claude/skills/wechat-article-publisher/scripts/:

wechat_api.py

WeChat API client for listing accounts and publishing articles:

# List authorized accounts

python wechat_api.py list-accounts

Publish from markdown file

python wechat_api.py publish --appid <wechat_appid> --markdown /path/to/article.md

Publish from HTML file (preserves formatting)

python wechat_api.py publish --appid <wechat_appid> --html /path/to/article.html

Publish with custom options

python wechat_api.py publish --appid --markdown /path/to/article.md --type newspic

### parse_markdown.py

Parse Markdown and extract structured data (optional, for advanced use):

python parse_markdown.py <markdown_file> [--output json|html]

## Workflow

**Strategy: "API-First Publishing"**

Unlike browser-based publishing, this skill uses direct API calls for reliable, fast publishing.

- Load WECHAT_API_KEY from environment

- List available WeChat accounts (if user hasn't specified)

- Detect file format (Markdown or HTML) and parse accordingly

- Call publish API to create draft in WeChat

- Report success with draft details

**Supported File Formats:**

- `.md` files → Parsed as Markdown, converted by WeChat API

- `.html` files → Sent as HTML, formatting preserved

## Step-by-Step Guide

### Step 1: Check API Key

Before any operation, verify the API key is available:

Check if .env file exists and contains WECHAT_API_KEY

cat .env | grep WECHAT_API_KEY

If not set, remind user to:

- Copy `.env.example` to `.env`

- Set their `WECHAT_API_KEY` value

### Step 2: List Available Accounts

Get the list of authorized WeChat accounts:

python ~/.claude/skills/wechat-article-publisher/scripts/wechat_api.py list-accounts

Output example:

{

"success": true,

"data": {

"accounts": [

{

"name": "我的公众号",

"wechatAppid": "wx1234567890",

"username": "gh_abc123",

"type": "subscription",

"verified": true,

"status": "active"

}

],

"total": 1

}

}

**Important**:

- If only one account, use it automatically

- If multiple accounts, ask user to choose

- Note the `wechatAppid` for publishing

### Step 3: Publish Article

**For Markdown files:**

python ~/.claude/skills/wechat-article-publisher/scripts/wechat_api.py publish \

--appid <wechatAppid> \

--markdown /path/to/article.md

**For HTML files (preserves formatting):**

python ~/.claude/skills/wechat-article-publisher/scripts/wechat_api.py publish \

--appid <wechatAppid> \

--html /path/to/article.html

**For 小绿书 (image-text mode):**

python ~/.claude/skills/wechat-article-publisher/scripts/wechat_api.py publish \

--appid <wechatAppid> \

--markdown /path/to/article.md \

--type newspic

Success response:

{

"success": true,

"data": {

"publicationId": "uuid-here",

"materialId": "uuid-here",

"mediaId": "wechat-media-id",

"status": "published",

"message": "文章已成功发布到公众号草稿箱"

}

}

### Step 4: Report Result

After successful publishing:

- Confirm the draft was created

- Remind user to review and publish manually in WeChat admin panel

- Provide any relevant IDs for reference

## Critical Rules

- **NEVER auto-publish** - Only save to drafts, user publishes manually

- **Check API key first** - Fail fast if not configured

- **List accounts first** - User may have multiple accounts

- **Handle errors gracefully** - Show clear error messages

- **Preserve original content** - Don't modify user's markdown unnecessarily

## Supported Formats

### Markdown Files (.md)

- H1 header (# ) → Article title

- H2/H3 headers (##, ###) → Section headers

- Bold (**text**)

- Blockquotes (> )

- Code blocks (`...`)

- Lists (- or 1.)

### HTML Files (.html)

- `<title>` or `<h1>` → Article title

- All HTML formatting preserved (styles, tables, etc.)

- `<img>` tags → Images auto-uploaded to WeChat

**HTML Title Extraction Priority:**

- `<title>` tag content

- First `<h1>` tag content

**HTML Content Extraction:**

- If `<body>` exists, uses body content

- Otherwise, strips `<html>`, `<head>`, `<!DOCTYPE>` and uses remaining content

## Example Flow

### Markdown File

User: "把 ~/articles/ai-tools.md 发布到微信公众号"

Step 1: Verify API key

cat .env | grep WECHAT_API_KEY

Step 2: List accounts

python ~/.claude/skills/wechat-article-publisher/scripts/wechat_api.py list-accounts

Step 3: Publish (assuming single account with appid wx1234567890)

python ~/.claude/skills/wechat-article-publisher/scripts/wechat_api.py publish \

--appid wx1234567890 \

--markdown ~/articles/ai-tools.md

Step 4: Report

"文章已成功发布到公众号草稿箱！请登录微信公众平台预览并发布。"

### HTML File

User: "把这个HTML文章发布到公众号：~/articles/newsletter.html"

Step 1: Verify API key

cat .env | grep WECHAT_API_KEY

Step 2: List accounts

python ~/.claude/skills/wechat-article-publisher/scripts/wechat_api.py list-accounts

Step 3: Publish HTML (auto-detects format)

python ~/.claude/skills/wechat-article-publisher/scripts/wechat_api.py publish \

--appid wx1234567890 \

--html ~/articles/newsletter.html

Step 4: Report

"文章已成功发布到公众号草稿箱！HTML格式已保留。请登录微信公众平台预览并发布。"

## Error Handling

### API Key Not Found

Error: WECHAT_API_KEY environment variable not set.

**Solution**: Ask user to set up `.env` file with their API key.

### Account Not Found

Error: ACCOUNT_NOT_FOUND - 公众号不存在或未授权

**Solution**: Ask user to authorize their account on wx.limyai.com.

### Token Expired

Error: ACCOUNT_TOKEN_EXPIRED - 公众号授权已过期

**Solution**: Ask user to re-authorize on wx.limyai.com.

### WeChat API Error

Error: WECHAT_API_ERROR - 微信接口调用失败

**Solution**: May be temporary issue, retry or check WeChat service status.

## Best Practices

### Why use API instead of browser automation?

- **Reliability**: Direct API calls are more stable than browser automation

- **Speed**: No browser startup, page loading, or UI interactions

- **Simplicity**: Single command to publish

- **Portability**: Works on any system with Python (no macOS-only dependencies)

### Content Guidelines

- **Images**: Use public URLs when possible; local images will be uploaded

- **Title**: Keep under 64 characters

- **Summary**: Auto-extracted from first paragraph if not provided

- **Cover**: First image in markdown becomes cover if not specified

### Workflow Efficiency

Minimal workflow (1 command):

• list-accounts → get appid → publish → done

Full workflow (with verification):

1. Check .env → list accounts → confirm with user

1. Publish with options → report result
