Description:
Writing manual JSON schemas for agent tools is repetitive and error-prone. In this lesson, learn how the OpenAI Agents SDK converts standard Python functions into production-grade agent capabilities using the function tool decorator, automatically extracting parameter types, default values, and docstrings.
Master both synchronous and asynchronous tool definitions, schema overrides, structured Pydantic inputs, and secure runtime context injection with RunContextWrapper. Discover how clean type hints and modular tool design eliminate model hallucinations and simplify unit testing.
