HTML Explainer

A Claude Skill for building polished, interactive HTML explainers as a single page OR a slide deck. Give it a topic, answer a few questions, and it produces a real page that someone can land on cold and come away understanding the basics.

It’s a process, not a template: the quality comes from an iterative loop (research → architect for learning → 10× the visual design → render-and-actually-look → revise), not from filling in blanks.

Best results: run it in Claude Code with Opus 4.8 at high effort (or better). It’s both faster and higher quality, since stronger first drafts mean fewer quality-loop fix cycles. Claude Code renders in a real headless browser, so it catches visual bugs the Claude App or Cowork cannot.

What it does

Given a topic (or your own source material), the skill:

• Scopes first — a short, must-ask interview: grounding, audience/depth, format (scrolling page vs slide deck), visual style, quiz, AI chat.
• Gets the facts right — grounds in your material and/or primary sources; cites them.
• Architects for learning — leads with one mental model, layers depth, builds around a single clear centerpiece.
• Hits a 10× visual bar — editorial typography, a semantic palette, real use of the horizontal space, and an explicit anti-“AI-slop” checklist (no emoji-as-icons, no decorative gradients, no generic bento grids).
• Shows, doesn’t tell — favors small playable micro-demos over paragraphs.
• Runs a real quality loop — renders the page in a headless browser, screenshots it (desktop + mobile + interactive states), critiques it like a human, and fixes what’s weak.
• Ships a real .html file with an optional in-page Review & edit overlay so non-technical reviewers can annotate or edit in place (and download a copy with both the edits and the notes embedded).
