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 | $0.00081 | $0.01402 |
| Opus 5 | $0.00041 | $0.00701 |
| Sonnet 5 | $0.00016 | $0.00280 |
| Haiku 4.5 | $0.00008 | $0.00140 |
Grade A, and why
animate-text 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.
How it starts
The opening of the file, as written. The whole thing — 86 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Animate Text
Use this skill as a text animation catalog backed by generated JSON contracts.
Use assets/specs/<id>.json for a portable motion contract. Use assets/effects/<id>.json for exact animation reproduction, including content, renderer algorithm, playback, runtime, host requirements, rendering contract, and library adapters.
This skill ships 24 specs in total. The website currently showcases 20 of them.
When To Use
Use this skill when the request involves:
- animating headings, labels, counters, editorial copy, or text swaps
- matching a named effect id such as
soft-blur-in,typewriter,shared-axis-y, orkinetic-center-build - choosing a motion pattern from a curated catalog and translating it into a target stack
- reproducing the current animation behavior in another stack without relying on example components
- implementing the same spec with WAAPI, Motion / motion.dev, GSAP, CSS, Lottie, Rive, or another renderer
Workflow
- Determine whether the user wants:
- the exact site version of a visible effect
- a portable translation of the motion contract
- If the user names an effect id, read
assets/specs/<id>.jsonor runnode scripts/get-spec.mjs <id>. - Otherwise use
references/catalog.mdor optionally run:node scripts/list-specs.mjsnode scripts/find-spec.mjs "<query>"
- Use
assets/specs/<id>.jsonwhen the user wants a portable translation of the motion intent. - Use
assets/effects/<id>.jsonornode scripts/get-effect.mjs <id>when the user wants the exact generated animation behavior. - If the user names a target animation library, treat that as binding. Follow
showcase.library_selectionand use only the matchingshowcase.library_adapters.<library>block for that effect. - For exact reproduction, follow
showcase.renderer,showcase.playback,showcase.timing,showcase.runtime,showcase.stage,showcase.rendering_contract,showcase.library_selection, andshowcase.library_adaptersover assumptions inferred from the portable spec alone. - Treat
showcase.stageas animation host requirements only. Do not copy typography, color, padding, card chrome, or page layout from the source website unless the user explicitly asks for that UI. - When applying an effect to an existing section, preserve that section's text. Use
showcase.contentonly as demo/fallback copy unless the user explicitly asks to reproduce the showcase copy.

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.
- 8d ago First seen · 86 lines · 81 tokens per session scan A 346d475ec128
animate-text is a skill published in the GitHub repository marvkr/better-design (228 stars, last pushed 18d ago), licensed MIT. It adds 81 tokens to every session and 1,402 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.
