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 | $0.00047 | $0.03593 |
| Opus 5 | $0.00023 | $0.01796 |
| Sonnet 5 | $0.00009 | $0.00719 |
| Haiku 4.5 | $0.00005 | $0.00359 |
Grade A, and why
mobile-design 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 5d 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.
This is a copy
97% identical to mobile-design — 7 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 394 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Mobile Design System
Philosophy: Touch-first. Battery-conscious. Platform-respectful. Offline-capable. Core Principle: Mobile is NOT a small desktop. THINK mobile constraints, ASK platform choice.
🔧 Runtime Scripts
Execute these for validation (don't read, just run):
| Script | Purpose | Usage |
|---|---|---|
scripts/mobile_audit.py |
Mobile UX & Touch Audit | python scripts/mobile_audit.py <project_path> |
🔴 MANDATORY: Read Reference Files Before Working!
⛔ DO NOT start development until you read the relevant files:
Universal (Always Read)
| File | Content | Status |
|---|---|---|
| mobile-design-thinking.md | ⚠️ ANTI-MEMORIZATION: Forces thinking, prevents AI defaults | ⬜ CRITICAL FIRST |
| touch-psychology.md | Fitts' Law, gestures, haptics, thumb zone | ⬜ CRITICAL |
| mobile-performance.md | RN/Flutter performance, 60fps, memory | ⬜ CRITICAL |
| mobile-backend.md | Push notifications, offline sync, mobile API | ⬜ CRITICAL |
| mobile-testing.md | Testing pyramid, E2E, platform-specific | ⬜ CRITICAL |
| mobile-debugging.md | Native vs JS debugging, Flipper, Logcat | ⬜ CRITICAL |
| mobile-navigation.md | Tab/Stack/Drawer, deep linking | ⬜ Read |
| mobile-typography.md | System fonts, Dynamic Type, a11y | ⬜ Read |
| mobile-color-system.md | OLED, dark mode, battery-aware | ⬜ Read |
| decision-trees.md | Framework/state/storage selection | ⬜ Read |
🧠 mobile-design-thinking.md is PRIORITY! This file ensures AI thinks instead of using memorized patterns.
Platform-Specific (Read Based on Target)
| Platform | File | Content | When to Read |
|---|---|---|---|
| iOS | platform-ios.md | Human Interface Guidelines, SF Pro, SwiftUI patterns | Building for iPhone/iPad |
| Android | platform-android.md | Material Design 3, Roboto, Compose patterns | Building for Android |
| Cross-Platform | Both above | Platform divergence points | React Native / Flutter |

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-design is a skill published in the GitHub repository ivanshtokov/copilot-kit (2 stars, last pushed 7mo ago), licensed MIT. It adds 47 tokens to every session and 3,593 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 97% identical to mobile-design, differing in 7 lines, and is treated as a copy.
