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 | $0.00032 | $0.01409 |
| Opus 5.5 | $0.00013 | $0.00564 |
| Sonnet 5.5 | $0.00006 | $0.00282 |
| Haiku 4.5 | $0.00003 | $0.00141 |
Grade A, and why
mobile-uiux-promax 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 — 140 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Mobile UI/UX Pro Max
Data-grounded mobile design intelligence. Every design decision is backed by platform-authoritative data from Apple HIG, Material Design 3, and stack-specific best practices.
When to Activate
Activate this skill when the request involves:
- Designing any mobile screen, flow, or component
- Reviewing mobile UI for platform-appropriateness
- Choosing between navigation patterns for mobile apps
- Implementing gesture-driven or haptic-rich interactions
- Advising on iOS vs Android design conventions
- Building onboarding flows or paywall timing
- Animation and motion design for mobile
Workflow
Run the 4-step search sequence from: .agent/workflows/mobile-uiux-promax.md
Read the workflow file before responding. It contains the exact search commands to run.
Core Design Principles (Memorize These)
1. Platform-First, Not Platform-Only
- Follow platform conventions by default
- Deviate only when there's clear UX benefit to users
- Cross-platform apps must feel native on each platform, not identical
- iOS users expect swipe-back + tab bar at bottom; Android users expect system back + nav structure
2. Thumb Zone Above All
- Primary actions belong in the bottom 60% of the screen
- Top-left corner = hardest to reach one-handed
- Platform back buttons (iOS top-left) are the only justified exception
3. Gesture + Haptic + Visual = One Interaction
- Every interaction should engage all three senses when appropriate
- Swipe reveals → haptic at threshold + visual action button
- Toggle → haptic on state change + visual state update simultaneously
- Pull-to-refresh → haptic on trigger + spinner animation + announce to screen readers
4. Accessibility Is Not Optional
- Minimum touch target: 44pt (iOS) / 48dp (Android)
- Every tappable element without visible text needs
accessibilityLabel - Every gesture needs an accessible alternative action
- Test with VoiceOver (iOS) and TalkBack (Android) before shipping
- Support Dynamic Type / sp font scaling (never lock font size)
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-uiux-promax is a skill published in the GitHub repository bonnguyenitc/antigravity-superpowers (20 stars, last pushed 5mo ago), licensed MIT. It adds 32 tokens to every session and 1,409 once invoked, about $0.0001 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.
