android-kmp-shared

android-kmp-shared is a skill for Claude Code, Codex from prasad-vennam/Awesome-Android-AI-Agent-Skills. It costs 32 tokens per session (801 once invoked), scanned A, original, MIT.

Guidance for Kotlin Multiplatform, which lets Android and iOS apps share Kotlin code while keeping platform-specific code where needed. It covers shared business logic, networking, databases, and dependency setup.

In plain words
What is it for?
Use it to share view models, use cases, data models, authentication, calculations, network access, or database logic between Android and iOS. It covers the shared, Android-specific, and iOS-specific source sets and tools such as Ktor, SQLDelight, and Koin.
Why use it?
Maintaining the same rules separately in Android and iOS apps can lead to duplicated work and inconsistent behavior. A shared module keeps common logic in one place while each platform supplies its own implementation when necessary.

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

android-kmp-shared 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 11d 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.

Android Kotlin Multiplatform (KMP) 🌍🤝

Professional patterns for sharing code between Android and iOS using the next-generation Kotlin Multiplatform technology.

⚡ When to Use

  • Shared Business Logic: Centralizing ViewModels, Use Cases, and Domain Models.
  • Data Layer Sharing: Using Ktor (Network) and SQLDelight (Database) across platforms.
  • Modularization: Creating a cross-platform library module.
  • Migration: Moving from 100% native to shared logic.
  • Validation: Building one logic for both apps (e.g., Auth, Calculations).

🏗️ The Multiplatform Architecture

  • commonMain: The heart of the app. Pure Kotlin code shared by all platforms.
  • androidMain: Platform-specific implementation for Android.
  • iosMain: Platform-specific implementation for iOS (via Kotlin/Native).

🛠️ Essential Shared Tools

1. Ktor (Networking)

  • Benefit: Async, multiplatform HTTP client.
  • Use ContentNegotiation and Serialization for shared DTOs.

2. SQLDelight (Local Persistence)

  • Benefit: Type-safe SQL queries that generate Kotlin code.
  • Shared schema, platform-specific drivers (SQLite for Android, Native for iOS).

3. Koin (Dependency Injection)

  • Benefit: Simple and lightweight DI that works across commonMain.

4. kotlinx-datetime

  • Use for consistent date/time logic without platform-specific issues (java.time vs NSDate).

🚀 The expect / actual Pattern

  • Use for platform-specific APIs when no shared library exists.
  • Rule: Avoid expect/actual if a shared library is available.
  • Bad: expect fun getPlatformName(): String
  • Good: Use interfaces and DI to provide platform-specific implementations.

🏁 Shared Logic Workflow

  • ViewModel Sharing: Use multiplatform-viewmodel library for consistent lifecycle mapping.
  • State Management: Use StateFlow in commonMain to expose UI state.
  • iOS Interoperability: Be aware of Swift/Kotlin memory management and @ObjCName for clean iOS APIs.

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.
