wtf is ultimate-design?

Ultimate Design is a skill you add to an AI coding assistant so it can handle design work in a structured way rather than guessing. Instead of jumping straight to making a webpage, poster, or dashboard, it walks the AI through a set process: it first clarifies what you actually want, writes a short design contract file called DESIGN.md when the task calls for it, pulls in relevant design knowledge, then builds the actual page or graphic. After building it, the AI is meant to critique its own work, fix problems it finds, and check the rendered result before calling it done. It is meant to work with AI coding tools that support agent skills, including Codex, Claude Code, and Pi Agent. You install it by running one command with npx, choosing which of those tools you are targeting, and then you invoke it inside a conversation by mentioning the skill by name along with what you want designed, such as turning a report into a clear web page. There is also a pro mode that pauses to agree on the important design decisions with you before the AI starts building. The kinds of work it covers include marketing websites, product interfaces and dashboards, slide decks made in HTML, posters and social graphics, overall brand systems, and reviews of a project's existing design or its motion and animation choices. For checking the visual result, it expects the AI to actually render the page and look at it using whatever browser or screenshot tools the host tool has available, and it also ships a few optional command line checks like flow-check and okf-graph-check for environments that support running them. The project is released under the MIT license.
