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 | $0.00023 | $0.00544 |
| Opus 5 | $0.00012 | $0.00272 |
| Sonnet 5 | $0.00005 | $0.00109 |
| Haiku 4.5 | $0.00002 | $0.00054 |
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
- Respect
prefers-reduced-motion- Always check and honor - No autoplay animation - Let users trigger motion
- Keep focus visible - Never animate focus indicator away
- Announce changes - Use ARIA live regions for dynamic content
- 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.

accessibility-issues is a skill published in the GitHub repository dylantarre/animation-principles (81 stars, last pushed 8mo ago), licensed MIT. It adds 23 tokens to every session and 544 once invoked, about $0.0001 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 2026-09-03.
