Anthropic tool search

Anthropic's tool use capability enables Claude to execute client-side functions and retrieve real-time data via structured JSON output.

Anthropic's tool use (also known as function calling) transforms Claude from a static model into an active operator capable of manipulating external systems. By providing the model with specific tool definitions (including names, descriptions, and input schemas), developers allow Claude to pause generation and request execution of external code. This architecture supports complex workflows like real-time stock price retrieval, database queries, and automated API interactions. The system relies on the `forced_tool_choice` parameter for precise control and handles multi-step reasoning to orchestrate several tool calls in a single turn.
