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 | $0.00055 | $0.00695 |
| Opus 5.5 | $0.00022 | $0.00278 |
| Sonnet 5.5 | $0.00011 | $0.00139 |
| Haiku 4.5 | $0.00006 | $0.00069 |
Grade A, and why
mobile-app-ui-ux 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 — 54 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Mobile App UI/UX
Portable rules for native / Expo product surfaces. Complements react-native-expo (implement) and web-app-ui-ux (web).
When to use
| Surface | This skill |
|---|---|
| Phone/tablet product screens, tabs, stacks, sheets | Yes |
| Safe areas, system bars, touch targets, gestures | Yes |
| Marketing landing / web-only chrome | No → taste-design / web-app-ui-ux |
| FlatList perf, SecureStore, Expo Router files | No → react-native-expo |
| Design Contract compositions / SaaS blocks | Pair with saas-product-ui |
Hard rules
- Safe areas first — content never under notch, status bar, home indicator, or Android system bars; use SafeAreaProvider + insets (or platform equivalent).
- Touch targets — interactive controls ≥ 44×44 CSS px (WCAG 2.5.8 minimum); pad with hitSlop when icon is smaller; space adjacent targets.
- Primary navigation — bottom tabs / top-level destinations ≤5; stacks for hierarchy; sheets/modals for focused tasks — no third competing global nav.
- Thumb zone — primary CTAs and destructive confirms reachable one-handed; avoid critical actions only in far top corners on tall phones.
- System chrome — status/nav bar style matches screen luminance; do not hide system bars for ordinary product flows.
- Gestures — back/dismiss must not fight OS edge gestures; always offer a visible control alternative to swipe-only actions.
- Async states — every async region: loading + error + empty×2 (first-use vs filtered); empty explains why and next action.
- Forms — visible labels; large fields; correct keyboard types; avoid nested scroll traps.
- Motion — honor reduced-motion; short transitions; no scroll-jacking.
- Density — product scan over marketing whitespace; one primary CTA per screen.
Anti-patterns
- Web hamburger-only IA on phone when destinations are peer-level (prefer bottom tabs)
- Controls under home indicator / cutout
- 24px icons with no expanded hit area
- Swipe-only destructive actions
- Desktop tables with no mobile list/card alternative
- Marketing bento / hero inside authenticated app shell
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.

mobile-app-ui-ux is a skill published in the GitHub repository phuoctrung-ppt/ai-sdlc-workflow (2 stars, last pushed 1mo ago), licensed MIT. It adds 55 tokens to every session and 695 once invoked, about $0.0002 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 2026-09-08.
