What is article-to-html-skill?

article-to-html is a skill (a small plugin) for Codex, an AI coding assistant. Its job is to convert a written document, such as a Markdown file, a pasted draft, or a proposal in a chat conversation, into a single, self-contained HTML file that looks like a printed paper or formal report. The output is a single file with all styles, graphics, and optional interactivity embedded directly inside it, with no dependencies on external fonts, content delivery networks, or remote images. The visual style is deliberately paper-like: a light off-white background, serif body text, monospace headers, numbered sections, and a required summary block near the top. Optional features include collapsible sections, copy buttons, dark mode, and filterable tables, all powered by plain JavaScript with no frameworks. You would use this when you want Codex to take something you have written and turn it into a polished, shareable static web page, for example, converting an infrastructure proposal, an RFC (request for comments), or a design document into an HTML file you can email or host on any web server. It is not intended for slide decks, multi-page websites, or anything that needs a live backend. The skill itself has no build step or runtime dependencies, it is purely a prompt-and-template bundle that instructs Codex on how to generate the HTML.
