The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Real A/B, rendered in-browser: the skill build produced a genuinely playable Doppler-shift canvas demo with color-coded compressed/stretched wavefronts, editorial serif/sans typography, and a real assemble.mjs-injected review overlay, against a baseline that was exactly the emoji-hero/gradient-text/bento-card template the skill's own anti-slop checklist warns about.

What HTML Explainer does

A heavyweight process skill (scoping interview, research cap, anti-slop visual design system, mandatory playable micro-demos, screenshot-and-critique quality loop) for turning a topic into a self-contained interactive HTML explainer. Triggers on requests to build an interactive explainer, guide, walkthrough, or one-pager, or to turn material into a visual web page people can explore.
