RN WeChat Extract

Extract the full text of a WeChat public account article into clean Markdown.

This skill is a source reader — it extracts and returns text. It does not summarize, rewrite, translate, or produce video.

How It Works

WeChat blocks external access to public account articles through User-Agent detection: the server checks for the MicroMessenger keyword and rejects normal browser requests.

This skill sends HTTP requests with a genuine WeChat iOS WebView User-Agent and the correct Referer header, which is sufficient to receive the full article HTML. No login, cookie, or API key is needed.

Extracts: title, author, publish time, and body text as Markdown.

Limitations:

Images are not downloaded (WeChat uses lazy-loaded data-src)
Some heavily JS-rendered articles may return partial content
Rapid successive calls from the same IP may trigger CAPTCHA (wait and retry)
Does not work on login-gated or paid articles

Locate The Skill

WX_HOME="$(
  for d in "$(pwd)/.codex/skills/rn-wechat-extract" \
           "$(pwd)/.agents/skills/rn-wechat-extract" \
           "$(pwd)/.claude/skills/rn-wechat-extract" \
           "$(pwd)/rnskill/skills/rn-wechat-extract" \
           "$HOME/.codex/skills/rn-wechat-extract" \
           "$HOME/.agents/skills/rn-wechat-extract" \
           "$HOME/.claude/skills/rn-wechat-extract"; do
    [ -f "$d/SKILL.md" ] && echo "$d" && break
  done
)"
export WX_HOME

Workflow

Health check (optional):

python3 "$WX_HOME/scripts/fetch_wechat.py" --doctor

Extract article:

python3 "$WX_HOME/scripts/fetch_wechat.py" "<mp.weixin.qq.com URL>" \
  --output-dir "<desired output directory>"

The script prints a JSON result to stdout:

{
  "status": "ok",
  "title": "文章标题",
  "author": "公众号名称",
  "publish_time": "2026-07-14 00:18",
  "char_count": 7025,
  "output_path": "path/to/extracted.md"
}

Read the output file and present the full text or pass it to the next skill.
On failure:
- Exit 1 (fetch/CAPTCHA): suggest retry after a few minutes or ask the user to paste text
- Exit 2 (parse failure): rerun with --raw to save HTML for debugging
