html-video is a local tool that turns HTML, CSS, and data into animated MP4 videos using configurable rendering engines and templates. Coding agents use it to create and export videos on a user's machine, with optional AI-generated soundtracks. The catalogue skills operate the tool and its video-generation workflow.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00030 | $0.01207 |
| Opus 5 | $0.00015 | $0.00603 |
| Sonnet 5 | $0.00006 | $0.00241 |
| Haiku 4.5 | $0.00003 | $0.00121 |
Grade A, and why
frame-data-chart-nyt scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
100% identical to frame-data-chart-nyt — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
【模板: NYT 风数据图表帧】 【意图】把一段数据 (CSV / JSON / 一句结论) 做成《纽约时报》专栏感的单帧/动画图表, 适合视频片段或推特卡。Inspired by hyperframes data-chart。
【画布】1920×1080, 暖白底 #f7f5ee 或墨黑底 #0e0e0e 二选一; 文字色和背景相反。
【布局】
- 顶部 kicker (11px uppercase letterspace 0.14em, 颜色 = accent 红
#a91d1d或 mint#5fb38a): 数据来源 + 类目, 如 "GLOBAL · WEEKLY ACTIVE USERS · 2018–2026"。 - 大字标题 (Cheltenham / Playfair / Source Serif Pro, 5.6vw, italic 副标可选): 一句结论。结论必须从用户数据中提炼, 不是描述图。
- 图表区 (占画布 55-65%):
- 折线: 1-2 条线, 主线 ink 实心 2.5px, 次线 dashed 1.5px; 数据点用 6px 实心圆; 关键点旁标注
2024 · 412M黑色 mono 小字。 - 柱状: 全部 ink 单色或加 1 道 accent 高亮柱; 柱顶大数字; 柱底类目斜体 (Cheltenham italic)。
- 范围带 (range band): 浅灰填充
#e6e2d2包络 + 中线 ink。
- 折线: 1-2 条线, 主线 ink 实心 2.5px, 次线 dashed 1.5px; 数据点用 6px 实心圆; 关键点旁标注
- 底部 source + footnote (10px mono, opacity 0.6): "Source: 用户数据 · Chart by html-anything"。
- 错峰揭示动画: 标题 fade-in (0s), kicker (200ms), 折线 stroke-dashoffset 1.2s ease-out (400ms), 数据标签依次 100ms 间隔。可被
prefers-reduced-motion关闭。
【设计细节】
- 绝不: 使用 chart.js / d3 库 (除非 jsdelivr CDN 引入); 推荐手写 SVG, 不超过 80 行 inline。
- 字体: 标题
Source Serif Pro或Cheltenham(无则用Playfair Display); bodyIBM Plex Sans或Inter; 数据标签IBM Plex Mono。 - 1 个主色 (ink) + 1 个 accent (NYT red
#a91d1d/ 编辑 mint#5fb38a/ 暖橙#d97757三选一)。 - Y 轴刻度仅 hairline + 3-4 个 tick, 标签在轴外侧 mono 字。
- 严禁 grid 全屏铺线、阴影、3D 立体柱; 严禁 emoji。
- 必须用用户提供的数据。如果输入是文本结论, 自动估算合理坐标 (但要标注 "schematic"); 如果是 CSV/JSON, 直接绘制。
- 单文件 HTML; 数据点旁注释格式:
<text class="annot">2024 · 412M</text>。
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
