Streaming Claude responses in TypeScript uses the SDK's event-based handlers to deliver tokens in real time. Initialize the Anthropic client, call `messages.stream()`, and listen to content block events to build responses incrementally without waiting for completion.

Tool use with Claude enables function calling through the SDK's tool-definition and tool-result workflow. Define tools with schemas, pass them to Claude, handle tool_use blocks in responses, execute your functions, and return results to continue the conversation.

Robust error handling for Claude integration includes exponential backoff retry logic, rate-limit detection, and timeout management. The SDK patterns cover transient failure recovery and graceful degradation to prevent cascading failures in production deployments.

Token optimization strategies include reusing system prompts across requests, managing conversation history with token budgets, and batching operations. These patterns reduce costs and latency in high-volume or multi-turn conversational workflows.

Type-safe SDK usage ensures compile-time safety for message schemas, tool definitions, and response handling. TypeScript patterns prevent runtime errors and provide autocomplete for streaming events, tool parameters, and API responses.

Deployment-ready patterns combine streaming, tool calling, error handling, and retry logic into production workflows. The SDK supports building chatbots and AI agents that execute external functions in real time with robust failure handling.
