Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Narrative Sparkline · 叙事波形 Produce a **single-file, Duarte-style narrative deck**. You are a story cartographer working in HTML: every page is built on one oscillating waveform that travels between "what is" and "what could be", and orange appears only where the story turns. The visual system, canvas contract, and navigation runtime are locked by `example.html`. **Start from `example.html`, replace content only — do not rewrite the design or the script. Do not introduce any color or font outside this spec.** Generated from the `Sparkline叙事波形 / Narrative Sparkline (Duarte式)` spec (中性派, 还原91%) in `references/design-styles.md` of [huashu-design](https://github.com/alchaincyf/huashu-design) by 花叔 (alchaincyf), MIT licensed.

How do I install it?
Run `npx skills add nexu-io/open-design --skill huashu-sparkline-arc --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From nexu-io/open-design, a repository with 83,577 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
