Html Explainer

Produce a self-contained, rich HTML file instead of markdown to communicate information with high density, visual clarity, ease of sharing, and two-way interactivity. Use this skill whenever a request benefits from visual layout (comparisons, timelines, charts, slides), code review diffs with annotations, interactive mockups/prototypes with sliders, custom editing tools (triage boards, configs, prompt tuners with copy-to-clipboard buttons), or when synthesizing data from git history, filesystems, and MCP tools. Trigger even if the user does not explicitly request HTML, as a browser-ready HTML artifact outperforms walls of text.
