Given an article, the skill builds a local HTML preview page that shows it as WeChat-compatible rich HTML, with a button labeled 复制 HTML that copies the article for pasting into the WeChat editor. The article's meaning and content stay as they are; only light structural changes are allowed, such as normalizing heading levels, splitting very long paragraphs and turning obvious lists or tables into styled blocks.
You choose one of three styles: Claude, a warm off-white editorial look; OpenAI, crisp white with a documentation feel; or Google, bright white with soft colored accents and modular cards. If you leave it to the agent, reflective writing gets Claude, technical or tutorial content gets OpenAI, and data or comparison pieces get Google. references/style-guide.md is read only when applying or comparing styles.
The preview is a single static index.html where possible, or follows the structure of an existing Vite app, with a toolbar, a centered content area at 677px maximum width, a status message after copying and a mobile layout. Copying uses the Clipboard API with HTML and plain-text formats and falls back to execCommand. The copied article uses inline styles only, with no external CSS, scripts, web fonts or CSS variables.
