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 | $0.00056 | $0.06220 |
| Opus 5 | $0.00028 | $0.03110 |
| Sonnet 5 | $0.00011 | $0.01244 |
| Haiku 4.5 | $0.00006 | $0.00622 |
Grade A, and why
design-motion-design 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.

Motion Design
Purpose
Design motion systems for digital products: animation principles, micro-interactions, transitions, Lottie animations, and motion guidelines that enhance user experience. Motion should serve a functional purpose — guiding attention, providing feedback, communicating hierarchy, and creating continuity between states.
Agent Protocol
Trigger
Exact user phrases: "motion design", "animation", "micro-interaction", "Lottie", "transition", "UI animation", "motion guidelines", "easing", "keyframe animation", "spring animation", "motion system".
Input Context
- What is the product type and platform (web, mobile, native)?
- What is the purpose of the animation (feedback, navigation, delight)?
- What existing motion system or design system is in place?
- What are the performance constraints (device targets, frame rate)?
- What accessibility requirements exist (reduced motion preferences)?
- What is the animation complexity budget?
Output Artifact
Motion design system with animation principles, duration/easing specifications, micro-interaction patterns, and implementation guidelines.
Response Format
## Motion Design Specification
### Animation Principles
{principle}: {application}
### Timing Scale
{action}: {duration} | {easing} | {use case}
### Micro-interaction Patterns
{pattern}: {trigger} → {animation} → {feedback}
### Implementation
{platform}: {technique} | {code example}
No preamble. No postamble. No explanations.
Completion Criteria
- Motion principles defined and documented
- Timing scale established with duration and easing values
- Micro-interaction patterns cataloged
- Page/view transitions specified
- Loading and progress animations designed
- Reduced motion fallback defined
- Lottie animation specifications (if applicable)
- Implementation guidance for developers
Max Response Length
150 lines of spec and patterns.
Framework/Methodology
Functional Motion Framework
All motion in UI should serve one of four functional roles:
What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

design-motion-design is a skill published in the GitHub repository j4flmao/agent-skills (23 stars, last pushed 5d ago), licensed MIT. It adds 56 tokens to every session and 6,220 once invoked, about $0.0003 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.
Other skills, from other repositories
gradient-text
Give one short headline quiet premium emphasis: a slow on-brand gradient drifts through the type. One phrase per view; never body copy (readability). Pure CSS; falls back to a solid brand color under prefers-reduced-motion.
magnetic-button
Make a primary button feel alive by gently pulling it toward the cursor as it approaches, then springing back. Keep it subtle and reserve it for one or two primary actions. Disabled on touch and under prefers-reduced-motion. Do not use it on dense UIs full of buttons.
ripple-press
Acknowledge a tap/click with a ripple that blooms from the exact press point. Fast and low-opacity so it reads as feedback, not decoration. No ripple under prefers-reduced-motion (native :active covers it). Avoid on destructive actions and text links.
scroll-reveal
Reveal content as it scrolls into view — a gentle rise + fade, once per element. Use to give a long page calm rhythm. Honors prefers-reduced-motion and supports staggering. Do not delay above-the-fold content, and keep at most a few elements animating at once.
motion-lexicon
Design, build, compose, implement, review, and contribute polished product interfaces with Motion Lexicon components and motion primitives. Use this skill when a user asks for a complete React page, landing page, dashboard, settings screen, or product surface in the Motion Lexicon visual language; asks what motion…
lottie-fab
A floating action button that morphs open — Lottie JSON. A Lottie (JSON) animation — portable motion that plays identically on web and app via lottie-web. Honors prefers-reduced-motion (don't autoplay). Reserve Lottie for motion that earns its 160KB runtime.
