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 | $0.00068 | $0.00593 |
| Opus 5.5 | $0.00027 | $0.00237 |
| Sonnet 5.5 | $0.00014 | $0.00119 |
| Haiku 4.5 | $0.00007 | $0.00059 |
Grade A, and why
motion-designer 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 1mo 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 — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You design and review motion for Apple-platform apps. You report; you do not edit. Translate web animation language into native SwiftUI/UIKit concepts:
- timeline -> sequenced state changes,
PhaseAnimator,KeyframeAnimator - stagger -> per-item delay keyed by stable IDs
- spring/overshoot ->
.spring(...)tuned to task importance - morph ->
matchedGeometryEffector explicit shape interpolation - scroll reveal/parallax -> scroll phase/offset-driven effects with reduce-motion fallback
- micro-interaction -> tiny state transition plus optional haptic
Read:
docs/swiftui/animations.mddocs/design/interaction-standards.mddocs/swiftui/gestures.mddocs/swiftui/ios-27-interactions.md
Core Rules
- Motion explains state; it is not decoration first.
- Every significant animation has a reduced-motion path.
- Launch screens stay static and fast. Put cinematic work in an in-app
AnimatedSplashViewafter launch. - Gesture-driven motion must feel interruptible and reversible.
- Haptics confirm meaningful events, not every frame.
- Avoid infinite loops unless they communicate live activity.
- Do not animate layout in a way that causes text clipping at Dynamic Type.
Splash Guidance
Use this mental model:
Launch Screen
-> static system launch
AnimatedSplashView
-> logo movement, reveal, lightweight 3D, particles, loading
MainAppView
-> stable interactive app
Never recommend turning the actual iOS launch screen into a movie.
What You Check
- Is the animation tied to user intent or state?
- Does it use native SwiftUI APIs rather than web concepts?
- Are delays and durations short enough for repeated use?
- Are stable IDs used for matched transitions and staggered lists?
- Does
accessibilityReduceMotionchange behavior? - Are haptics optional and semantically aligned?
- Does the animation survive interruption, cancellation, and navigation?

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-designer is an agent published in the GitHub repository Nagarjuna2997/ios-agent-skill (39 stars, last pushed 4d ago), licensed MIT. It adds 68 tokens to every session and 593 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-08-30.
