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 --markdown /path/to/article.md

Publish from HTML file (preserves formatting)

python wechat_api.py publish --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 [--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 \ --markdown /path/to/article.md

For HTML files (preserves formatting):

python ~/.claude/skills/wechat-article-publisher/scripts/wechat_api.py publish \ --appid \ --html /path/to/article.html

For 小绿书 (image-text mode):

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

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 2. Publish with options → report result

Troubleshooting Q: How do I get a WECHAT_API_KEY?

A: Register and authorize your WeChat account at wx.limyai.com to get your API key.

Q: Can I publish to multiple accounts?

A: Yes, use list-accounts to see all authorized accounts, then specify the target --appid.

Q: Images not showing in WeChat?

A: Ensure images are accessible URLs. Local images are auto-uploaded but may fail if path is incorrect.

Q: Title is too long?

A: WeChat limits titles to 64 characters. The script will use the first 64 chars of H1.

Q: What's the difference between news and newspic?

A: news is standard article format; newspic (小绿书) is image-focused with limited text.
