motion-review-gate

motion-review-gate is a skill for Codex from markoblogo/abvx-agent-skills. It costs 82 tokens per session (981 once invoked), scanned A, original, MIT.

A review checklist for frontend animation and motion, such as transitions, menus opening, or gesture effects. It checks whether motion is useful, accessible, responsive, and safe for performance.

In plain words
What is it for?
Use it when reviewing CSS animations, Framer Motion, Lottie, drawers, popovers, tooltips, toasts, modals, hover states, or gestures before release.
Why use it?
It catches animation that is distracting, too slow, hard to interrupt, inaccessible to people who prefer less motion, or costly for the browser to render.

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-review-gate 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.

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 Review Gate

Review motion as a pre-ship gate. This skill does not design a whole interface and does not rewrite unrelated frontend code.

Use it after implementation or during review when the diff includes animation, transitions, gestures, Lottie assets, interaction states, or motion-heavy UI polish. Pair it with browser-verification when the visual behavior must be checked in a real browser. When a diff includes drag, swipe, momentum, snap points, or another direct-manipulation gesture, also run fluid-interaction-review; this gate alone does not fully verify gesture physics.

Use For

  • CSS transitions, keyframes, @starting-style, WAAPI, Framer Motion, Motion, or Lottie changes;
  • drawers, popovers, menus, dropdowns, tooltips, toasts, command palettes, modals, hover states, press states, and gestures;
  • frontend diffs where animation might hurt speed, accessibility, or product feel;
  • checking whether motion should be removed rather than polished.

Do Not Use For

  • general frontend critique without motion-specific risk;
  • visual hierarchy, brand direction, or typography review without interaction/motion changes;
  • full accessibility or performance audits beyond animation-related issues.

Review Order

  1. Purpose — every animation must serve feedback, spatial consistency, state indication, explanation, or prevention of jarring change.
  2. Frequency — keyboard-triggered and 100+ times/day actions should not animate; frequent actions should be reduced.
  3. Timing and easing — most UI motion stays under 300ms; avoid ease-in for UI response; prefer strong ease-out or appropriate custom curves.
  4. Physicality — avoid scale(0); popovers, menus, and tooltips should originate from their trigger; modals can stay centered.
  5. Interruptibility — rapidly triggered UI should retarget smoothly; prefer transitions or springs over restart-prone keyframes.
  6. Performance — animate transform and opacity; avoid layout properties and parent CSS-variable recalc storms.
  7. Accessibility — respect prefers-reduced-motion; gate hover motion behind real hover media queries.
  8. Cohesion — motion should match the product surface: crisp for dashboards, more expressive only when the brand or moment earns it.

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.
