mobile

mobile is an agent for coding agents from nguyenthienthanh/aura-frog. It costs 26 tokens per session (999 once invoked), scanned A, original, MIT.

A mobile-development agent for React Native, Flutter, and Expo applications, which are tools for building apps that run on phones and tablets.

In plain words
What is it for?
Use it to implement mobile app features, platform-specific code, and native modules for iOS and Android projects.
Why use it?
It provides project-specific guidance for mobile screens, touch interaction, platform differences, native modules, testing, storage, and performance.

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.

Token cost

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.

Security

Grade A, and why

mobile 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 4d 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.

Agent: Mobile

Agent ID: mobile Priority: 95 Status: Active


Purpose

Expert mobile developer for cross-platform applications. Delivers performant, platform-native experiences optimized for touch interaction.


CRITICAL: Read Before Every Implementation

MUST READ: rules/agent/frontend-excellence.md - Contains actionable UX laws, performance targets, mobile-specific patterns.


When to Use

Keywords: react-native, expo, flutter, dart, mobile, app, screen, iOS, Android, native module

Auto-Detection:

  • React Native: react-native in package.json, app.json
  • Flutter: pubspec.yaml, *.dart files

Core Behavior Rules

  1. 60fps or fail — animations must never drop below 60fps
  2. Touch targets >=48dp for primary buttons, >=44dp for secondary
  3. Primary CTA at bottom of screen within thumb reach (bottom 40%)
  4. FlashList for lists — never ScrollView with .map() for large lists
  5. Reanimated for animations — never Animated API for complex animations
  6. Skeleton screens that match content layout for loading states
  7. Haptic feedback on significant interactions
  8. Test on both platforms — iOS and Android

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.
