motion-and-animation

motion-and-animation is a skill for Claude Code from HalidSaglam/saglitzdesign-mcp. It costs 104 tokens per session (989 once invoked), scanned A, original, MIT.

A set of rules and examples for adding movement to user interfaces, such as menus, dialogs, page changes, and button feedback.

In plain words
What is it for?
Use it when adding or fixing interface animations, including transitions, hover effects, presses, drawers, modals, gestures, and support for reduced motion.
Why use it?
It helps avoid motion that feels abrupt, confusing, or out of place by choosing suitable timing, easing, and movement behavior.

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-and-animation 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.

The opening of the file, as written. The whole thing — 65 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Motion & Animation

Motion exists to explain (where did this come from?), confirm (did that work?), and occasionally delight. If an animation does none of those, delete it. The details compound — wrong easing or a scale(0) pop is the difference between "premium" and "cheap."

Full depth is in the SaglitzDesign MCP (npx saglitzdesign-mcp): docs animation-craft, motion-microinteractions, wwdc-design-principles; tools generate_motion (easing/duration tokens + ready keyframes in CSS, Framer Motion or SwiftUI, reduced-motion included) and compare_design_languages("motion") for per-platform physics.

Easing — the rule agents get wrong

  • Enter: ease-out (fast start, gentle landing). Elements arriving decelerate.
  • Exit: ease-in, and faster than the enter (~2/3 the duration). Dismiss quickly.
  • Move / reposition: ease-in-out.
  • Never linear for UI — only for spinners and continuous progress.

Using ease-in for an enter (or ease everywhere by default) makes motion feel broken even if users can't say why.

Durations

  • Micro feedback (press, toggle, hover): 100–150ms.
  • Small components (dropdown, tooltip, chip): 150–200ms.
  • Medium (modal, sheet, drawer): 200–300ms.
  • Page/screen transitions: 300–350ms. Nothing UI-blocking past ~400ms.

Springs (the modern default on mobile & rich UI)

  • Prefer springs over fixed-duration curves for anything gesture-driven or that can be interrupted — they feel natural and are inherently interruptible.
  • Tune with bounce + duration (Motion) or stiffness / damping / mass. Little to no bounce for functional UI; a touch of bounce for playful moments only.
  • Velocity handoff: a gesture's release velocity should flow into the spring, and momentum should project to where the gesture was going.

Interruptibility (the single most important principle — from Apple)

Animations must be redirectable mid-flight. If a user opens then immediately closes a sheet, it should reverse from its current position, never finish opening first. Use CSS transitions over keyframes for interruptible state, and springs that accept current velocity.

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-and-animation is a skill published in the GitHub repository HalidSaglam/saglitzdesign-mcp (5 stars, last pushed 9d ago), licensed MIT. It adds 104 tokens to every session and 989 once invoked, about $0.0005 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.
