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 5.1 | $0.00033 | $0.04180 |
| Opus 5 | $0.00016 | $0.02090 |
| Sonnet 5 | $0.00007 | $0.00836 |
| Haiku 4.5 | $0.00003 | $0.00418 |
Grade A, and why
animation-motion 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 11d 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.

UI Animation & Motion — Emil Kowalski Design Philosophy
Overview
Taste is trained, not innate. Animation excellence compounds through study and practice—most users never consciously notice individual polish, yet the collection creates stunning results. Beauty is leverage: aesthetic excellence is competitive advantage. This skill applies Emil Kowalski's battle-tested animation decision framework to ship production-grade motion.
When to Use This Skill
Use when:
- Designing animations for UI components (buttons, modals, dropdowns, popovers, tooltips)
- Reviewing animation implementations for performance and accessibility
- Deciding whether/how/how-fast to animate interactions
- Building gesture-driven interfaces (drag, swipe, hold)
- Optimizing motion for accessibility (prefers-reduced-motion)
- Creating staggered or spring-based animations
- Debugging animation timing, easing, or transform issues
Do NOT use for:
- Animation frameworks/libraries selection (use dedicated framework skills)
- Keyframe animation software (Figma, After Effects)
- SVG animation exclusively (this covers CSS/WAAPI)
The Animation Decision Framework
Question 1: Should This Animate at All?
Frequency is the primary gate:
| Frequency | Example | Decision |
|---|---|---|
| 100+ times/day | Keyboard shortcuts, frequently toggled UI | ❌ Never animate |
| Tens of times/day | Hover effects, toggle states | ⚠️ Remove or drastically reduce |
| Occasional (few per session) | Modals, toasts, notifications | ✅ Standard animation acceptable |
| Rare | Onboarding, celebrations, first-run | ✅ Can add delight |
| Keyboard-initiated | Any action from keyboard (return, space, etc.) | ❌ Never animate |
Golden rule: If users interact with it frequently, every millisecond of animation compounds into frustration.
Question 2: What Is the Purpose?
Valid animation purposes:
- Spatial consistency — clarify origin/destination (modal from center, popover from trigger)
- State indication — show what changed (button pressed, checkbox checked)
- Explanation — guide attention or teach (scroll hint, tooltip entrance)
- Feedback — confirm action received (keystroke feedback, form validation)
- Preventing jarring changes — smooth transitions between states
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.

animation-motion is a skill published in the GitHub repository fernando-bertholdo/4-successful-AI-life (2 stars, last pushed yesterday), licensed MIT. It adds 33 tokens to every session and 4,180 once invoked, about $0.0002 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 2026-08-31.
