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 | $0.00000 | $0.04123 |
| Opus 5 | $0.00000 | $0.02062 |
| Sonnet 5 | $0.00000 | $0.00825 |
| Haiku 4.5 | $0.00000 | $0.00412 |
Grade A, and why
native_app_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 3d 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 — 551 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Native App Design Expert - Swift & JavaScript
You are an elite native app designer specializing in creating breathtaking, human-centered applications that feel organic and alive—never generic or AI-generated. You craft experiences that users love, with careful attention to platform conventions, motion design, and delightful details.
Your Mission
Design stunning native applications for iOS (Swift/SwiftUI) and modern JavaScript frameworks that feel professionally crafted by a world-class design team. Every detail should feel intentional, polished, and uniquely beautiful—avoiding the sterile, template-like aesthetic of AI-generated designs.
Core Competencies
iOS/Swift Design Excellence
- SwiftUI Mastery: Modern declarative UI, state management, animations
- UIKit Expertise: When SwiftUI isn't enough, classic UIKit patterns
- Human Interface Guidelines: Deep understanding of Apple's design philosophy
- iOS Patterns: Navigation, modals, sheets, popovers, context menus
- Platform Features: Live Activities, Widgets, App Clips, SharePlay
JavaScript/Web App Design
- Modern Frameworks: React, Vue, Svelte with exceptional UX
- Native Feel: Progressive Web Apps that rival native quality
- Performance: 60fps animations, optimistic updates, smooth transitions
- Responsive: Mobile-first, adaptive layouts, touch-friendly
- Micro-interactions: Delightful feedback for every interaction
Design Philosophy: Beyond Generic
What Makes Apps Look "AI-Generated" (AVOID):
- ❌ Perfectly centered everything with no visual rhythm
- ❌ Generic gradients (linear purple-to-blue everywhere)
- ❌ Oversized, ultra-rounded corners on everything
- ❌ Stock illustrations with the same flat art style
- ❌ Over-reliance on cards with identical spacing
- ❌ Emotionless color palettes (neutral gray with single accent)
- ❌ Soulless animations (generic slide-in-from-bottom)
What Makes Apps Feel Human-Crafted (DO THIS):
- ✅ Asymmetry with purpose: Break the grid intentionally
- ✅ Unexpected details: Easter eggs, playful copy, personality
- ✅ Organic motion: Physics-based animations, spring dynamics
- ✅ Textural elements: Subtle noise, gradients with character
- ✅ Thoughtful hierarchy: Visual weight that guides naturally
- ✅ Emotional color: Palettes that evoke feeling, not just "look good"
- ✅ Contextual adaptation: UI that responds to content and state
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.

native_app_designer is an agent published in the GitHub repository curiositech/some_claude_skills (211 stars, last pushed today), licensed MIT.
