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 | $0.00141 | $0.01104 |
| Opus 5 | $0.00071 | $0.00552 |
| Sonnet 5 | $0.00028 | $0.00221 |
| Haiku 4.5 | $0.00014 | $0.00110 |
Grade A, and why
sprite-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 yesterday.
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 sprite-animation — 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.
How it starts
The opening of the file, as written. The whole thing — 95 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Sprite Animation Skill
Produce a single animated frame of an educational explainer — the kind you might screen-record into a vertical video. Pixel-art mascots, big year display, looping CSS animations, kinetic Japanese / English display type.
Workflow
- Read the active DESIGN.md (injected above). Pick the loudest serif token for the year, a sturdy sans for headlines, and a mono token for timeline / index labels.
- Pick the topic from the brief (e.g. "Nintendo · 1889 — Hanafuda"). You always need: a year, a one-line headline, an animated subject (a pixel sprite — character, object, or icon), and a short caption.
- Stage — full-bleed cream / off-white background (
#f5efe2) with a subtle paper grain. Keep margins generous; this is one beat of a video. - Top bar — small mono row:
- Left: title slug ("名次の/番組" or "EP. 01 / NINTENDO")
- Right: progress dots ("01 / 12") and a "REC" stamp
- Subject animations — at least three independent looping animations
on the page:
- Big year: the headline year (e.g. "1889年") fills the lower-left, in a serif display weight. It has a subtle vertical glitch / scanline animation (clip-path keyframes), and a 1-frame "pop" every loop.
- Pixel sprite card: a 96×128 pixel-art card or character (use an
inline SVG with crisp
shape-rendering: crispEdgesrectangles, or abox-shadowpixel grid). Subtle bobbing animation (±4px, 1.6s). - Kinetic kana: 1–2 Japanese / kanji characters that fade-and-slide in sync with the bob (e.g. "花" — hana — flower).
- Tick ribbon: bottom of the stage, a tape/ribbon with year ticks (1889 · 1907 · 1949 · 1977 · 1985 · 2006 · 2017) sliding left at a slow constant speed.
- Caption block — small mono caption explaining the trivia: "Nintendo started as a Hanafuda playing-card maker in Kyoto, 1889. Mario didn't show up for another ninety-six years."
- Write a single HTML document:
<!doctype html>through</html>, CSS inline, no external JS.- All animations use
@keyframes+animation: ... infinite. - Stage uses a fixed canvas ratio (e.g. 16:9 letterboxed) so the loop reads as a single frame from a video.
data-od-idon stage, year, sprite, caption, and tick ribbon.
- Self-check:
- The page is one cohesive scene, not a collage. The eye lands on the year first, then the sprite, then the caption.
- At least 3 independent looping animations are visible.
- The color palette is restrained (cream + a single accent red + ink).
- No external assets — all sprites are inline SVG or CSS.
What ships with it
1 file 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.

sprite-animation is a skill published in the GitHub repository wolfenazz/YzPzCode (13 stars, last pushed today), licensed Apache-2.0. It adds 141 tokens to every session and 1,104 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to sprite-animation, differing in 0 lines, and is treated as a copy.
