Handle Tool Calls

This guide walks through the complete workflow of defining a tool, streaming a response, handling tool calls, and returning results to the LLM.

Overview

The tool call workflow has four steps:

1. Define a Tool with a JSON Schema for its parameters.
2. Include the tool in the Context and stream a response.
3. When the LLM emits a ToolCallEndEvent, execute the tool.
4. Return the result as a ToolResultMessage and continue the conversation.
