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.

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 | $0.00104 | $0.00989 |
| Opus 5 | $0.00052 | $0.00495 |
| Sonnet 5 | $0.00021 | $0.00198 |
| Haiku 4.5 | $0.00010 | $0.00099 |
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.
How it starts
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): docsanimation-craft,motion-microinteractions,wwdc-design-principles; toolsgenerate_motion(easing/duration tokens + ready keyframes in CSS, Framer Motion or SwiftUI, reduced-motion included) andcompare_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
linearfor 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.
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.

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.

design
Use when the user wants the visual/experiential design of a product done systematically — a design system, a screen, a landing page, or a visual identity — grounded in researched real-world prior art and free of AI slop.

logo-creator
Create logos using AI image generation. Discuss style/ratio, generate variations, iterate with user feedback, crop, remove background, and export as SVG. Use when user wants to create a logo, icon, favicon, brand mark, mascot, emblem, or design a logo.
handoff-spec
Write the implementation handoff — measurements, behaviours, assets, states, and edge cases. Use when engineering picks up the work. For verifying the result afterwards use design-qa-checklist; for reusable library components use component-spec (design-systems).
animation-principles
Apply animation principles — easing, staging, follow-through — to one specific UI motion. Use when tuning how an animation feels. For product-wide duration and easing tokens use motion-system (design-systems); for a full interaction spec use micro-interaction-spec.
readable-measure
Set line length and measure for comfortable reading across type sizes and breakpoints. Use when tuning body text. Covers measure only — for the full size and weight scale, use typography-scale.
von-restorff-effect
Apply the Von Restorff Effect — the element that differs from its neighbours is the one remembered. Use when a single action must dominate. For overall ordering rather than single-element emphasis, use visual-hierarchy.
