motion-craft

motion-craft is a skill for Claude Code, Codex from EliasOulkadi/shokunin. It costs 98 tokens per session (6,697 once invoked), scanned A, original, MIT.

Guidance for designing web animations and transitions with browser animation tools. It focuses on motion that explains interface changes, including scroll effects, page transitions, and support for reduced-motion preferences.

In plain words
What is it for?
Use it to plan and implement GPU-friendly animations, scroll-driven effects, layout transitions, easing rules, and reduced-motion behavior.
Why use it?
It helps prevent distracting or slow animations and makes motion clearer and more accessible.

Token cost

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.

Security

Grade A, and why

motion-craft 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/generate-easing.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 696 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Motion Craft

Animations that communicate, not decorate. Every frame must earn its place.

Inspired by Emil Kowalski (Linear, Sonner, Vaul), Paul Lewis (Google Chrome), and the CSS Animation Working Group.

Workflow

The Animation Decision Framework

Before writing any animation code, answer these four questions in order.

1. Should this animate at all?

Frequency Decision Reason
100+ times/day (keyboard shortcuts, command palette, search toggle) No animation. Ever. Animation makes frequent actions feel delayed. Raycast has no open/close animation. Optimal.
Tens of times/day (hover effects, list navigation) Remove or drastically reduce Users notice animation latency on repeated interactions
Occasional (modals, drawers, toasts) Standard animation The right place for motion
Rare / first-time (onboarding, confirmation, celebration) Add delight These moments earn longer, richer animations

Never animate keyboard-initiated actions. These repeat hundreds of times daily.

2. What is the purpose?

Every animation must have a clear answer to "why does this animate?"

Purpose Example Valid?
Spatial consistency Toast enters and exits from the same direction ?
State indication Button morphs to show "sent" ?
Feedback Button scales down on press, confirming the interface heard the user ?
Preventing jarring changes Elements fading in instead of appearing abruptly ?
Explanation Marketing animation showing how a feature works ?
"It looks cool" AND the user sees it often Gratuitous motion ?

3. What easing should it use?

Scenario Easing CSS
Element entering ease-out (starts fast, feels responsive) cubic-bezier(0, 0, 0.2, 1)
Element exiting ease-in (starts slow, grabs attention briefly then accelerates away) cubic-bezier(0.4, 0, 1, 1)
On-screen movement / morphing ease-in-out cubic-bezier(0.4, 0, 0.2, 1)
Hover / color change ease cubic-bezier(0.25, 0.1, 0.25, 1)
Constant motion (marquee, progress bar) linear cubic-bezier(0, 0, 1, 1)
UI interactions (buttons, tooltips, dropdowns) strong ease-out cubic-bezier(0.23, 1, 0.32, 1)

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.
