ux-motion

ux-motion is a command for coding agents from Laith0003/ux-skill. It costs 104 tokens per session (3,518 once invoked), scanned A, original, MIT.

A command that reviews animations and transitions in an interface against rules for timing, easing, purpose, reduced-motion support, and performance. Reduced motion is an accessibility setting that asks software to limit movement.

In plain words
What is it for?
Use it with a live URL, screen recording, animation-related CSS or JavaScript, or a code snippet to review the interface's motion.
Why use it?
It identifies motion that is distracting, inaccessible, slow, or unnecessary and separates changes to keep, tune, or remove. Static screenshots are not enough because the movement itself must be observed.

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.

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

ux-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 6d 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.

The opening of the file, as written. The whole thing — 303 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/ux-motion

You are running the /ux-motion command from the ux plugin. The job is to evaluate every animation on a surface against five dimensions — timing, easing, meaning, reduced-motion compliance, performance — and identify what to keep, what to tune, and what to kill.

When to use

Triggers: "motion check", "are the animations good", "fix the motion", "review the animations", "motion audit", "is this too much animation", "the motion feels off", "performance pass on the motion".

Use after building a motion-rich surface, after a redesign that added new transitions, or when something "feels wrong" but the user cannot name it. Not for layout or copy issues — those are /ux-audit and /ux-copy.

Input

One of: a live URL (preferred — motion is observable), a screen recording, a CSS/JS file with animation definitions, or a code snippet. Static screenshots are insufficient — flag and request a recording or live URL.

Process

1. Inventory every animation

List every animation present, including:

  • CSS transitions on hover, focus, active states.
  • CSS keyframe animations (loaders, indicators, attention-grabbers).
  • JS-driven animations (libraries: GSAP, Framer Motion, Motion One, Web Animations API).
  • Scroll-linked animations (parallax, scroll-tied transforms, scroll-triggered reveals).
  • Page-transition animations.
  • Micro-interactions (button press, checkbox tick, toggle slide).
  • Implicit animations (carousel auto-advance, marquee, autoplay video).

For each, note: trigger, duration, easing, properties animated, scope (single element or page-wide).

2. Evaluate each animation on five dimensions

Dimension 1 — Timing
  • Micro-interactions (button press, hover state, checkbox tick): 150–250ms. Anything ≥ 300ms feels sluggish on micro.
  • Component transitions (modal open, drawer slide, toast appear): 200–300ms.
  • Complex transitions (page transitions, multi-element choreography): up to 400ms — beyond that, the user starts waiting.
  • Loaders / indicators: continuous, but the loop should be 800–1500ms to feel alive without nagging.

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.
