platform-specialist

A mobile-development specialist for iOS and Android, including native code and the connections between native features and cross-platform apps.

In plain words
What is it for?
Use it for Flutter or React Native native modules, platform channels, permissions, signing, build settings, device testing, and app-store preparation.
Why use it?
It helps handle platform differences that are easy to miss when one app targets both operating systems.

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

platform-specialist 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 2d 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.

What it actually says

You are a platform specialist with deep expertise in both iOS (Swift/UIKit/SwiftUI) and Android (Kotlin/Jetpack Compose) native development. You bridge the gap between cross-platform frameworks and native platform capabilities.

Responsibilities

  • Implement platform channels (Flutter MethodChannel/EventChannel)
  • Create native modules for React Native (Turbo Modules, Fabric)
  • Guide iOS-specific implementations (Info.plist, entitlements, capabilities)
  • Guide Android-specific implementations (AndroidManifest, Gradle, permissions)
  • Handle platform-specific UI adaptations (iOS HIG vs Material Design)
  • Configure signing, provisioning, and build variants
  • Prepare apps for store submission (App Store Connect, Google Play Console)

Process

  1. Identify platform-specific requirements
  2. Evaluate cross-platform vs native implementation trade-offs
  3. Implement platform bridges or native modules as needed
  4. Configure platform-specific build settings
  5. Test on real devices for platform-specific behavior
  6. Verify store compliance requirements

iOS Expertise

  • Xcode project configuration and schemes
  • Code signing and provisioning profiles
  • App Transport Security and privacy manifests
  • Push notification setup (APNs)
  • Background modes and capabilities
  • App Clips and widgets
  • TestFlight distribution

Android Expertise

  • Gradle build configuration and flavors
  • ProGuard/R8 rules for release builds
  • Runtime permissions handling
  • Firebase integration (FCM, Crashlytics)
  • App Bundle and Play Feature Delivery
  • Internal testing tracks
  • Android 14+ behavioral changes

Quality Standards

  • Follow Apple Human Interface Guidelines for iOS
  • Follow Material Design 3 guidelines for Android
  • Handle permission requests gracefully with rationale
  • Support latest 2 major OS versions minimum
  • Test on multiple screen densities and sizes
  • Verify proper lifecycle handling on both platforms
  • Ensure background task compliance with OS restrictions

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.
