accessible-animation

accessible-animation is a skill for Claude Code from 2233admin/design-pipeline. It costs 98 tokens per session (2,969 once invoked), scanned A, a copy of accessible-animation, MIT.

A guide to making interface animation respect the user's reduced-motion accessibility setting, which asks software to limit movement that may cause nausea, dizziness, or migraines.

In plain words
What is it for?
Use it to audit or adapt CSS, GSAP, Framer Motion, Lenis, Anime.js, and other web animations for reduced-motion users and accessibility requirements.
Why use it?
It helps prevent motion-related discomfort while preserving useful feedback such as focus indicators and loading progress.

Token cost

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.

Security

Grade A, and why

accessible-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 6d 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.

Accessible Animation (Reduced Motion, Tiered)

Honor prefers-reduced-motion: reduce as a graceful degradation, not a kill switch. The OS-level setting (macOS: Settings > Accessibility > Display > Reduce motion; Windows: Settings > Accessibility > Visual effects > Animation effects; iOS/Android equivalents) signals that vestibular-triggering motion causes nausea, dizziness, or migraines. The correct response is to remove the dangerous motion while keeping orientation cues.

When to use

Use when adding or auditing animation in a web UI, when a user reports motion sickness or WCAG findings, or when integrating animation libraries (GSAP, Framer Motion, Lenis smooth scroll, Anime.js, CSS keyframes) into an accessible product.

The core principle: tier motion, do not nuke it

Removing all animation is a common over-correction. An instant state change with no transition can be more disorienting (elements teleport) and removes useful affordances (focus rings, loading spinners that communicate progress). Sort every animation into three tiers:

  • Tier 1 — Remove entirely (vestibular triggers). Parallax; large-area slides/translates across the viewport; scale/zoom of large elements; 3D rotation and spin; continuous auto-playing carousels and marquees; smooth-scroll hijacking (Lenis/Locomotive); scroll-jacked pinned scenes; motion-path animation; anything that moves a large portion of the screen or implies depth/self-motion.
  • Tier 2 — Soften / shorten. Replace movement with a short opacity fade (≤200ms). Reduce distance and duration. Keep the fact of a transition (so elements don't teleport) but strip the displacement. Replace a 600ms slide-in-from-left with a 150ms cross-fade.
  • Tier 3 — Always keep. Opacity fades, color/background transitions, focus-ring transitions, loading indicators, and motion that is essential to meaning (WCAG allows essential animation). These rarely trigger vestibular responses because they imply no self-motion.
