description	Create native modules with sequential native-bridge-builder then code-reviewer agents

/native-module — Create Native Module

You are executing the /native-module command. Run native-bridge-builder first (create the module), then code-reviewer (review it). This is sequential, not parallel.

Phase 1: native-bridge-builder — Scaffold & Implement

Determine Module Type

Ask the user or detect from project:

1. Expo Modules API — For Expo managed projects (recommended)
2. Turbo Module — For bare React Native projects (New Architecture)
3. Fabric Component — For custom native views

Scaffold the Module

Generate all required files based on module type:

Expo Module (6 files):

modules/[module-name]/
  expo-module.config.json     # Module configuration
  src/[ModuleName]Module.ts   # TypeScript API definition
  ios/[ModuleName]Module.swift # Swift implementation
  android/src/main/java/.../[ModuleName]Module.kt  # Kotlin implementation
  src/__tests__/[ModuleName].test.ts  # Unit tests
  README.md                   # Usage documentation

Implementation Guidelines

• Define clear TypeScript interface first (contract)
• Implement Swift and Kotlin to match the contract
• Handle errors consistently (reject Promises with error codes)
• Use async/await in Swift, coroutines in Kotlin
• Include JSDoc comments on the TypeScript API

Phase 2: code-reviewer — Review the Module

After module creation, automatically run code review:

• Verify TypeScript types match native implementations
• Check error handling on both platforms
• Validate threading (no main thread blocking)
• Review memory management (cleanup, listeners)
• Check platform parity (same behavior iOS/Android)

Output

• Scaffolded module files with implementation
• Code review results
• Usage example in React Native
