Agent skills answer questions with interactive HTML instead of plain text

Instead of making the agent reply with prose, a skill instructs it to produce a one-page interactive HTML artifact: a diagram, a visual summary, or an explorable UI that the user can click through. This turns complex answers or architecture explanations into something visual and shareable rather than a wall of text.

What it is

This move adds a reusable skill to your coding agent (Claude Code, Codex, Cursor, OpenCode, Copilot, and similar tools) that changes the output format of an answer. Instead of the agent replying with markdown or a wall of prose, it produces a single self-contained HTML file: a diagram, an explorable map, or a small interactive page that answers the question directly. Two examples of this pattern are answer-me-with-html, which turns a hard question into a one-page HTML explainer, and Archify, which turns a described system, plan, or codebase into a validated interactive diagram.

How to do it

  • Install the skill into your agent's skills directory, for example with a package command like npx skills add or by dropping the skill folder into the project so the agent can discover it.
  • Ask your question in plain language, the same way you normally would. No special syntax is needed to trigger the skill.
  • Let the agent pick the right visual shape for the question: architecture, workflow, sequence, data flow, or lifecycle, depending on what you asked.
  • Open the generated HTML file in a browser. It should work offline with zero runtime dependencies, so you can click through it, scroll or pan around larger diagrams, and in some implementations toggle between light and dark themes.
  • Iterate by chatting instead of hand-editing the file: ask the agent to move a step, rename a node, or recolor an element, then regenerate the page.
  • Export or share the artifact directly, for example attaching the HTML file to an email or a pull request comment, or exporting a snapshot in formats like PNG, SVG, or WebP if the skill supports it.

When it helps

This is most useful for architecture explanations, multi-step workflows, state machines, and other answers that are naturally spatial or relational rather than linear. It also fits situations where you want to hand the explanation to someone else without walking them through paragraphs of text.

Pitfalls

The visual format is better suited to structured, relational content; a straightforward factual answer may not benefit from the extra step. Treat generated diagrams as a draft to check, since an agent can still misrepresent relationships even when the output looks polished and interactive.
