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 | $0.00087 | $0.02116 |
| Opus 5 | $0.00044 | $0.01058 |
| Sonnet 5 | $0.00017 | $0.00423 |
| Haiku 4.5 | $0.00009 | $0.00212 |
Grade A, and why
logo-animation 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 12d 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.

How it starts
The opening of the file, as written. The whole thing — 149 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Logo Animation
Bring a brand mark to life with one clear idea, on-brand geometry, and a crisp settle. Animate for web (SVG/Lottie), video intros/outros, or app splash screens, and always ship a static end-frame fallback.
When to use
- Build an intro stinger, sign-off, app splash, or loader idle loop.
- Reveal a brand mark on a landing hero or sizzle reel.
- Draw on an SVG mark, wipe/build it in piece by piece, or morph an icon into a wordmark.
- Sync the final settle of the mark to a sound-logo beat.
Core principle
Pick ONE technique per logo — draw OR build OR morph — not all at once. Reveals run 0.8–2.5s. Never distort brand geometry; scale and fade are safe, skew and squash usually are not. Respect clearspace (keep the mark's minimum margin clear of motion debris). Always provide a prefers-reduced-motion path that shows the final mark with no motion.
Technique map
| Technique | Best for | Mechanism |
|---|---|---|
| Stroke draw-on | Line marks, monograms, signatures | stroke-dashoffset 1→0 |
| Mask wipe / reveal | Filled shapes, gradients | animate a <clipPath> / <mask> rect |
| Build-on (stagger) | Multi-piece marks, grids | per-group opacity+transform, staggered |
| Morph | Icon ↔ wordmark, shape→logo | GSAP MorphSVG or matched path interpolation |
| Idle loop | Loaders, ambient splash | seamless cyclic transform (rotate/pulse) |
| Wordmark | Logotypes | per-letter mask/translate stagger |
Quick start: SVG stroke draw-on
The fastest on-brand web reveal. Each path draws itself, then fills settle in.
<svg viewBox="0 0 200 80" id="logo">
<path class="ink" d="M10 60 L40 20 L70 60" fill="none"
stroke="#111" stroke-width="6" stroke-linecap="round"
pathLength="1" stroke-dasharray="1" stroke-dashoffset="1"/>
</svg>
<style>
@keyframes draw { to { stroke-dashoffset: 0; } }
#logo .ink { animation: draw 1.1s cubic-bezier(.65,0,.35,1) forwards; }
@media (prefers-reduced-motion: reduce) {
#logo .ink { animation: none; stroke-dashoffset: 0; }
}
</style>
What ships with it
2 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.

logo-animation is a skill published in the GitHub repository iart-ai/motion-design-skills (28 stars, last pushed 2mo ago), licensed MIT. It adds 87 tokens to every session and 2,116 once invoked, about $0.0004 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.
