Agentic Orchestration
Tool Use & Function Calling
Build agents that can use external tools. Learn to define schemas, handle errors, and guard dangerous operations.
An LLM can reason about data, but it can't fetch stock prices or query a database. Tools bridge this gap—they let agents take actions in the real world.
But tools are also dangerous. A poorly designed tool can leak data, rack up API costs, or execute unintended operations. This tutorial teaches you to build safe, reliable tool-using agents.
What You'll Learn
- How tool calling works under the hood
- Define tools with clear schemas the LLM can understand
- Build a multi-tool agent that chooses which tool to call
- Handle tool errors without crashing the agent
- Guard dangerous tools with confirmation prompts
