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 | $0.00089 | $0.06478 |
| Opus 5 | $0.00044 | $0.03239 |
| Sonnet 5 | $0.00018 | $0.01296 |
| Haiku 4.5 | $0.00009 | $0.00648 |
Grade A, and why
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 2d 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 Animation Library
Overview
Motion (package: motion, formerly framer-motion) is the industry-standard React animation library used in production by thousands of applications. With 30,200+ GitHub stars and 300+ official examples, it provides a declarative API for creating sophisticated animations with minimal code.
Key Capabilities:
- Gestures: drag, hover, tap, pan, focus with cross-device support
- Scroll Animations: viewport-triggered, scroll-linked, parallax effects
- Layout Animations: FLIP technique for smooth layout changes, shared element transitions
- Spring Physics: Natural, customizable motion with physics-based easing
- SVG: Path morphing, line drawing, attribute animation
- Exit Animations: AnimatePresence for unmounting transitions
- Performance: Hardware-accelerated, ScrollTimeline API, bundle optimization (2.3 KB - 34 KB)
Production Tested: React 19.2, Next.js 16.1, Vite 7.3, Tailwind v4
When to Use This Skill
✅ Use Motion When:
Complex Interactions:
- Drag-and-drop interfaces (sortable lists, kanban boards, sliders)
- Hover states with scale/rotation/color changes
- Tap feedback with bounce/squeeze effects
- Pan gestures for mobile-friendly controls
Scroll-Based Animations:
- Hero sections with parallax layers
- Scroll-triggered reveals (fade in as elements enter viewport)
- Progress bars linked to scroll position
- Sticky headers with scroll-dependent transforms
Layout Transitions:
- Shared element transitions between routes (card → detail page)
- Expand/collapse with automatic height animation
- Grid/list view switching with smooth repositioning
- Tab navigation with animated underline
Advanced Features:
- SVG line drawing animations
- Path morphing between shapes
- Spring physics for natural bounce
- Orchestrated sequences (staggered reveals)
- Modal dialogs with backdrop blur
Bundle Optimization:
- Need 2.3 KB animation library (useAnimate mini)
- Want to reduce Motion from 34 KB to 4.6 KB (LazyMotion)

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.

motion is a skill published in the GitHub repository fellipeutaka/leon (5 stars, last pushed 4d ago), licensed MIT. It adds 89 tokens to every session and 6,478 once invoked, about $0.0004 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.
