Tool Development and Integration for AI Agents

AI agents are only as powerful as the tools they can access. To build truly useful applications, you must know how to connect large language models to external data sources, custom APIs, and local services safely and reliably. This text-based course guides you from the absolute basics of tool calling to designing robust, custom integrations. You will understand how agents parse instructions, select tools, and process results, enabling you to build smarter, action-oriented AI systems. What you'll learn: Understand the core mechanics of function calling and how LLMs interact with external tools; Design structured schemas to define precise inputs and outputs for your custom tools; Build integrations that connect AI agents to web APIs, databases, and local file systems; Implement robust error handling and fallback strategies when tools fail or return unexpected data; Apply modern security practices, including input validation, to run agent tools safely. The course begins with foundational definitions of agent architectures and tool-calling interfaces, then moves step-by-step through writing schemas, connecting APIs, and securing your integrations. This program is designed for developers and AI enthusiasts new to agentic workflows, with no prior tool development experience required.
