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 | $0.00061 | $0.02306 |
| Opus 5 | $0.00030 | $0.01153 |
| Sonnet 5 | $0.00012 | $0.00461 |
| Haiku 4.5 | $0.00006 | $0.00231 |
Grade A, and why
design-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 5d 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.
How it starts
The opening of the file, as written. The whole thing — 333 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Motion Design Skill
Degree of freedom: MIXED. Purpose and timing [HIGH freedom]; existing
motion inventory and reduced-motion [LOW freedom — run exactly].
Create purposeful, performant animations that enhance UX without overwhelming users.
How to reason
- Inventory — existing motion library and
prefers-reduced-motion - Purpose — feedback, orientation, focus, or (rare) delight
- Implement —
transform/opacityonly; match the app's timing - Motion-safe — reduced-motion becomes an instant state change
Worked example
Inventory: Framer Motion already on the modal; no reduced-motion branch. Purpose: orientation — show the dialog arriving, not decoration. Implement: opacity + scale 0.95→1, 200ms ease-out; no
heightanimation. Motion-safe:prefers-reduced-motionskips enter/exit; focus still moves.
Self-critique before reporting
- Purpose named — not motion for its own sake
- GPU-only — no width/height/top/left animation
- Reduced-motion proven — a reduce setting was actually tested
- Right owner — app-wide coherent motion pass →
enhance-motion
CRITICAL: Check Existing First [LOW freedom — run exactly]
Before adding ANY animation, verify:
- Check for existing animation utilities:
cat package.json | grep -i "framer-motion\|gsap\|animat"
rg "motion\.|animate\(|useSpring" --type tsx -l | head -10
- Check for existing CSS animations:
rg "@keyframes|animation:" --type css
cat tailwind.config.* | grep -A20 "animation\|keyframes"
- Check for animation preferences:
rg "prefers-reduced-motion" --type tsx --type css
Why: Maintain consistent animation language. Respect user motion preferences.
Animation Principles [HIGH freedom]
1. Purpose-Driven Motion
Every animation should serve a purpose:
- Feedback - Confirm user actions (button press, form submit)
- Orientation - Show where elements come from/go to
- Focus - Direct attention to important elements
- Delight - Add personality (use sparingly)
What ships with it
1 file 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 is a skill published in the GitHub repository kensaurus/cursor-kenji (9 stars, last pushed 10d ago), licensed MIT. It adds 61 tokens to every session and 2,306 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.
