What is html-it?

html-it is a skill for Claude Code, the AI coding assistant, that teaches it to produce polished HTML pages as output instead of plain markdown text. Markdown is the simple formatted text, with asterisks for bold and dashes for lists, that most AI tools return by default. The idea comes from an article by a member of the Anthropic Claude Code team, and this project describes itself as one community implementation of that idea rather than the original source. The skill defines four escalating levels of HTML output. Level 1 is a Static Doc, in practice a prettier version of a report or plan with readable formatting. Level 2 is a Visual Artifact that adds diagrams drawn in SVG, tables, and layouts, suited to things like design systems or dashboards. Level 3 is Two Way Interactive, meaning the page includes sliders or toggles you can adjust plus a button that copies your chosen values back into a prompt. Level 4 is a Throwaway Tool, a small purpose built app such as a drag and drop ticket board, meant to be used once and discarded. You install the skill by cloning the repository into your Claude Code skills folder, either for all projects or just one. Once installed, it activates when you type the slash command html-it or phrases like "html this" or "render as html." The package also includes a fixed color palette and font stack, so pages it generates look consistent instead of like generic AI output. The README mentions a related project called tweak, which adds a live adjustment panel to any HTML page and pairs well with the Level 3 and 4 outputs this skill produces. The project is released under the MIT license and was built by RoboNuggets.
