Claude finished @jakubuid's task in 1m 27s —— View job Code ReviewIssue 1: Unsafe force unwrap causes potential crashID: posclient-force-unwrap-crash-3c9f The force unwrap operator Recommendation: Use safer initialization pattern: val newScope = CoroutineScope(SupervisorJob() + Dispatchers.IO)
this.scope = newScope
val tracker = EventTracker(merchantId, newScope)
this.eventTracker = tracker
this.apiClient = ApiClient(apiKey, merchantId, tracker)Issue 2: Currency parsing logic assumes specific formatID: eventmodels-currency-parse-assumes-5a2f The currency extraction Recommendation: Add validation or fallback: val currency = if (unit.contains("/")) {
unit.substringAfter("/")
} else {
unit // use full unit as currency if no "/" present
}Issue 3: Integer division truncates fractional amountsID: eventmodels-division-truncates-amount-8d41 The calculation Recommendation: Either document this assumption or make decimal places configurable based on currency type. At minimum, add a comment explaining the 2-decimal assumption. Issue 4: Exception handler only prints to stdoutID: eventtracker-exception-handler-stdout-2b7e The Recommendation: Use proper logging: private val silentExceptionHandler = CoroutineExceptionHandler { _, t ->
if (BuildConfig.DEBUG) {
Log.w("EventTracker", "Event tracking failed", t)
}
}Issue 5: Missing null-safety check on scope launchID: eventtracker-scope-null-launch-4f3a The Recommendation: Current implementation is acceptable, but consider adding documentation that this scope is expected to be active for the tracker's lifetime. Issue 6: Potential memory leak with coroutine scopeID: posclient-scope-leak-cleanup-9a1c The Recommendation: Consider using Issue 7: Date formatting not thread-safeID: eventtracker-date-format-thread-unsafe-6c8d
Recommendation: Use thread-safe date formatting: // Option 1: Create new formatter per use
private fun formatTimestamp(): String {
return SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", Locale.US).apply {
timeZone = TimeZone.getTimeZone("UTC")
}.format(Date())
}
// Option 2: Use Java 8+ DateTimeFormatter if minSdk allows
private val isoDateFormat = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'")
.withZone(ZoneId.of("UTC"))Automated Checks✅ No external domain URLs detected |

🤖 Auto Review Issue: Unsafe force unwrap causes potential crash
Severity: HIGH

Tool: Claude Auto Review
Recommendation: Use safer initialization pattern:
val newScope = CoroutineScope(SupervisorJob() + Dispatchers.IO)
this.scope = newScope
val tracker = EventTracker(merchantId, newScope)
this.eventTracker = tracker
this.apiClient = ApiClient(apiKey, merchantId, tracker)
