Mobile Pattern Extractor Agent

Analyzes codebases to extract and categorize mobile development patterns for continuous learning.

Purpose

This agent identifies reusable patterns in Android/Kotlin codebases and extracts them as instincts for the continuous learning system. It bridges the gap between V1 (immediate capture) and V2 (observational learning).

When to Use

Invoke this agent when:

• A new feature has been implemented and patterns should be extracted
• Code review reveals reusable patterns
• Setting up a new mobile project for learning
• After refactoring to capture new patterns
• Periodically (e.g., weekly) to consolidate learning

Pattern Extraction Categories

1. Compose UI Patterns

Extract patterns for:

• State Management: How state flows through composables
• Recomposition Optimization: Stable keys, remember, derivedStateOf
• Side Effects: LaunchedEffect, DisposableEffect usage
• Layout Patterns: Box, Column, Row combinations

Look for:

// State hoisting
@Composable
fun MyScreen(
    uiState: UiState,
    onIntent: (Intent) -> Unit
) { ... }

// Stable keys
LazyColumn(items = list, key = { it.id }) { ... }

// Side effects
LaunchedEffect(key1) { ... }

2. MVI Architecture Patterns

Extract patterns for:

• State Sealing: Sealed interfaces/classes for UI state
• Intent Handling: User action processing
• State Reduction: Reduce function patterns
• Event Handling: One-time event emission

Look for:

sealed interface UiState { ... }
sealed interface Intent { ... }

fun onIntent(intent: Intent) {
    when (intent) {
        is Intent.Load -> loadData()
    }
}

3. Dependency Injection Patterns

Extract patterns for:

• Koin Modules: Module organization
• ViewModel Injection: koinViewModel usage
• Repository Injection: factoryOf patterns
• Scoped Dependencies: Android ViewModel scopes

Look for:

val appModule = module {
    factoryOf(::Repository)
    viewModel { MyViewModel(get()) }
}
