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 | $0.00052 | $0.00794 |
| Opus 5 | $0.00026 | $0.00397 |
| Sonnet 5 | $0.00010 | $0.00159 |
| Haiku 4.5 | $0.00005 | $0.00079 |
Grade A, and why
animejs 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 8d 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
98% identical to animejs — 1 line 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.
How it starts
The opening of the file, as written. The whole thing — 116 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Anime.js for HyperFrames
HyperFrames can seek Anime.js instances through its animejs runtime adapter. The composition owns the animation objects; HyperFrames owns the clock.
Contract
- Create animations or timelines synchronously during composition initialization.
- Set
autoplay: falseso Anime.js does not advance on its own clock. - Register every returned animation or timeline on
window.__hfAnime. - Use finite durations and loop counts.
- Avoid callbacks that mutate DOM based on wall-clock time, network state, or unseeded randomness.
The adapter seeks every registered instance with instance.seek(timeMs), where timeMs is HyperFrames time in milliseconds.
Basic Pattern
<script src="https://cdn.jsdelivr.net/npm/[email protected]/lib/anime.iife.min.js"></script>
<script>
const anim = anime({
targets: ".mark",
translateX: 280,
rotate: "1turn",
opacity: [0, 1],
duration: 1200,
easing: "easeOutExpo",
autoplay: false,
});
window.__hfAnime = window.__hfAnime || [];
window.__hfAnime.push(anim);
</script>
Timeline Pattern
<script>
const tl = anime.timeline({
autoplay: false,
easing: "easeOutCubic",
});
tl.add({
targets: ".title",
translateY: [40, 0],
opacity: [0, 1],
duration: 650,
}).add(
{
targets: ".accent",
scaleX: [0, 1],
duration: 450,
},
250,
);
window.__hfAnime = window.__hfAnime || [];
window.__hfAnime.push(tl);
</script>
Module Builds
If you use an ES module build, the adapter does not care how the instance was created. It only needs the returned object to expose seek(), pause(), and preferably play():
<script type="module">
import { animate } from "https://cdn.jsdelivr.net/npm/animejs/+esm";
const anim = animate(".chip", {
x: "18rem",
duration: 900,
autoplay: false,
});
window.__hfAnime = window.__hfAnime || [];
window.__hfAnime.push(anim);
</script>
Good Uses
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.

animejs is a skill published in the GitHub repository anton-abyzov/vskill (45 stars, last pushed yesterday), licensed MIT. It adds 52 tokens to every session and 794 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 98% identical to animejs, differing in 1 line, and is treated as a copy.
