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.

What it costs to keep this loaded
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 | $0.00032 | $0.01178 |
| Opus 5 | $0.00016 | $0.00589 |
| Sonnet 5 | $0.00006 | $0.00236 |
| Haiku 4.5 | $0.00003 | $0.00118 |
Grade A, and why
frame-takram-organic 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 13d 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.

【画布】1920×1080, 米色底 #EFEAE0; 右侧叠 sage 绿径向 wash (rgba(122,158,127,0.10))。整体柔和、自然、有呼吸感。
【字体】西文 Manrope 700/600/400; 中文 Noto Sans SC。圆润, 不要太硬。

【内容纪律】

What ships with it
5 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.

frame-takram-organic is a skill published in the GitHub repository nexu-io/html-video (4,567 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 32 tokens to every session and 1,178 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
