Flutter app performance patterns for the Bro app. Use when modifying state management, widget rebuild logic, polling intervals, image handling, or SharedPreferences usage. Prevents UI jank, unnecessary rebuilds, memory leaks, and main-thread blocking. Consult before touching OrderProvider, HomeScreen, OrderStatusScreen, or BreezProvider.
Dispute resolution and auto-liquidation system for the Bro app. Use when modifying dispute flows, auto-liquidation timers, AI dispute agent, evidence handling, collateral/escrow, or any code in dispute_service.dart, dispute_detail_screen.dart, disputeAgentService.js, agent.js, or escrow.js. Prevents data loss from encrypted evidence, incorrect timer thresholds, and agent misconfiguration.
FCM push notification architecture for the Bro app. Use when modifying push notifications, FCM token registration, APNS configuration, background message handling, or any code in pushService.js, brix_relay_service.dart, background_notification_service.dart, or main.dart FCM sections. Prevents recurring bugs with iOS delivery, token lifecycle, and notification types.
Nostr relay synchronization architecture for the Bro app. Use when modifying relay connections, order sync logic, event fetching, WebSocket management, or any code in nostr_order_service.dart relay sections, nostr_service.dart, relay_service.dart, or OrderRealtimeService. Prevents event loss, sync races, subscription leaks, and relay-specific silent failures.
Security code review for vulnerabilities. Use when asked to "security review", "find vulnerabilities", "check for security issues", "audit security", "OWASP review", or review code for injection, XSS, authentication, authorization, cryptography issues. Provides systematic review with confidence-based reporting.
This skill should be used when working with the Nostr protocol, implementing Nostr clients or relays, handling Nostr events, or discussing Nostr Implementation Possibilities (NIPs). Provides comprehensive knowledge of Nostr's decentralized protocol, event structure, cryptographic operations, and all standard NIPs.
