accessibility-issues

accessibility-issues is a skill for Claude Code, Codex from dylantarre/animation-principles. It costs 23 tokens per session (544 once invoked), scanned A, original, MIT.

A guide to making animation usable for people with motion sensitivity, cognitive disabilities, or assistive technology needs.

In plain words
What is it for?
Use it to support reduced-motion settings, remove distracting movement, simplify transitions, and keep animated interfaces accessible.
Why use it?
It helps prevent dizziness, flashing-related risks, confusion, and lost keyboard focus caused by excessive or poorly controlled motion.

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

accessibility-issues 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 9d 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.

Accessibility Issues

Make animations inclusive using Disney's principles thoughtfully.

Problem Indicators

  • Motion sickness complaints
  • Vestibular disorder triggers
  • Screen reader confusion
  • Cognitive overload
  • Seizure risk (flashing)
  • Keyboard focus lost during animation

Diagnosis by Principle

Squash and Stretch

Issue: Excessive distortion causes disorientation Fix: Reduce or eliminate squash/stretch for users with prefers-reduced-motion. Use opacity changes instead.

Secondary Action

Issue: Too many moving elements Fix: Limit to one animated element at a time. Secondary actions should be subtle or removed.

Exaggeration

Issue: Dramatic motion triggers vestibular responses Fix: Reduce scale, rotation, and position changes. Keep movements small and predictable.

Timing

Issue: Animations too fast or too slow Fix: Provide consistent, predictable timing. Avoid sudden speed changes.

Arcs

Issue: Curved motion paths cause tracking difficulty Fix: Use linear motion for essential UI. Save arcs for optional decorative elements.

Quick Fixes

  1. Respect prefers-reduced-motion - Always check and honor
  2. No autoplay animation - Let users trigger motion
  3. Keep focus visible - Never animate focus indicator away
  4. Announce changes - Use ARIA live regions for dynamic content
  5. Provide pause controls - For any looping animation

Troubleshooting Checklist

  • Does animation respect prefers-reduced-motion?
  • Is there a way to pause/stop animations?
  • Are state changes announced to screen readers?
  • Does keyboard focus remain visible and logical?
  • Is flash rate under 3 per second?
  • Can users complete tasks without animation?
  • Are animations triggered by user action (not autoplay)?
  • Test with screen reader enabled

Code Pattern

@media (prefers-reduced-motion: reduce) {
  *,
  *::before,
  *::after {
    animation-duration: 0.01ms !important;
    animation-iteration-count: 1 !important;
    transition-duration: 0.01ms !important;
  }
}

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.
