wechat-html-check-no-div

Run the check-html.mjs script with Node.js against your final HTML file, for example node scripts/check-html.mjs article.ai.html. It exits with code 0 and outputs {"valid":true,"issues":[]} when the document passes all checks.

This gate flags div open tags, style tags, stylesheet links, script tags, on* event handlers, iframes, forms, and unprocessed Mermaid or ECharts code fences. It also detects fixed pixel dimensions on flow tags and content outside the html element.

No, the skill only inspects the HTML and reports issues as JSON; it never rewrites content. Fixing is delegated to a separate normalizer step, which the orchestrator may retry up to two rounds.

These issues appear when non-whitespace text exists before the doctype/html start or after the closing </html> tag. Remove the stray content so the document contains only a single clean HTML document.

The script uses only Node.js built-in modules (fs and path), so no npm packages need to be installed. Any recent Node.js runtime can execute it directly from the command line.
