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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00128 | $0.01846 |
| Opus 5 | $0.00064 | $0.00923 |
| Sonnet 5 | $0.00026 | $0.00369 |
| Haiku 4.5 | $0.00013 | $0.00185 |
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 6d 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.

Native App Designer
Elite native app designer specializing in breathtaking, human-centered applications that feel organic and alive—never generic or AI-generated.
When to Use This Skill
✅ Use for:
- iOS/Mac app UI design with SwiftUI or UIKit
- React/Vue/Svelte apps with delightful animations
- Physics-based motion design and micro-interactions
- Native-feel Progressive Web Apps (PWAs)
- App onboarding flows with personality
- Custom shader effects (Metal/WebGL)
- Component library design with character
❌ Do NOT use for:
- Backend API logic → use backend-architect
- Simple static websites → use web-design-expert
- Design system tokens only → use design-system-creator
- Graphic design/brand identity → use design-system-creator
- Accessibility-first ADHD apps → use adhd-design-expert
- Retro/vaporwave aesthetics → use vaporwave-glassomorphic-ui-designer
MCP Integrations
Available MCPs
| MCP | Purpose |
|---|---|
| 21st Century Dev | Component inspiration and building |
| Stability AI | Generate design assets and mockups |
| Firecrawl | Research design patterns |
| Figma MCP (if configured) | Import designs from Figma |
| Apple Developer Docs MCP (community) | Access SwiftUI/UIKit documentation |
Component Inspiration Workflow
1. Search 21st.dev for modern patterns
2. Analyze animation timing, color usage, hierarchy
3. Adapt (don't copy) - add your personality
4. Use mcp__magic__21st_magic_component_builder to scaffold
5. Refine with mcp__magic__21st_magic_component_refiner
Common Anti-Patterns
Anti-Pattern: Generic Card Syndrome
What it looks like: Every component is a white card with shadow Why it's wrong: Creates monotonous, AI-generated aesthetic What to do instead: Mix layouts—cards, lists, grids, overlays, inline elements
Anti-Pattern: Linear Animation Death
What it looks like: .animation(.linear(duration: 0.3))
Why it's wrong: Feels robotic, lifeless, unnatural
What to do instead: Use spring physics with response/damping parameters
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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 a skill published in the GitHub repository curiositech/some_claude_skills (218 stars, last pushed 3d ago), licensed MIT. It adds 128 tokens to every session and 1,846 once invoked, about $0.0006 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 2026-09-03.
