• HTTP Client: VanturaClient with connection pooling, 3-retry exponential backoff, and automatic HTTP 429 rate-limit handling.
• Memory System: VanturaMemory with short-term (recent messages) and long-term (LLM-summarized) memory, plus automatic pruning.
• Persistence Interface: Abstract VanturaPersistence — plug in any storage backend (SQLite, Hive, Firestore, etc.) without SDK modification.
• Tool Framework: Generic VanturaTool<T> base class with type-safe argument parsing, JSON Schema definitions via SchemaHelper, and human-in-the-loop confirmation support.
• Built-in Tools: CalculatorTool, NetworkConnectivityTool, DeviceInfoTool, ApiTestTool.
• Multi-Agent Coordination: AgentCoordinator class for routing conversations between specialist agents with automatic transfer_to_agent tool injection.
• Request Cancellation: CancellationToken for aborting generation mid-request at both the HTTP and reasoning-loop levels.
• Token Usage Tracking: TokenUsage object returned in VanturaResponse with promptTokens, completionTokens, and totalTokens.
• Error Callbacks: onToolError, onAgentFailure, and onWarning hooks on VanturaAgent for structured error reporting and telemetry.
• UI State Management: VanturaState (ChangeNotifier) for syncing agent status (isRunning, currentStep, errorMessage) with Flutter UI.
• Markdown Renderer: Zero-dependency MarkdownText Flutter widget supporting headers, bold, italic, inline code, bullet lists, and horizontal rules.
• Logger Interface: Abstract VanturaLogger with a default SimpleVanturaLogger (colored console output).
