This pull request proposes adding runtime validation to theAgent class in theopenai-agents-sdk to ensure thename attribute is a non-empty string. This change addresses the issue where non-string types (e.g., integers or dictionaries) are currently accepted, despite thestr type annotation, which can lead to unexpected behavior. By implementing validation, we make the SDK more robust and user-friendly.

Proposed Change

The proposed solution adds a__post_init__ method to theAgent class to validate thatname is a string and not empty or whitespace-only. This approach is standard for Python dataclasses and does not affect other attributes or methods.

Why It Matters

This change prevents potential errors, aligns with type annotations, and improves the user experience by providing clear feedback on invalid inputs. It benefits the community by making the SDK more reliable, encouraging adoption, and reducing support overhead.

The__post_init__ method is the most suitable, as it is lightweight, aligns with Python dataclass conventions, and requires minimal changes to the existing codebase.
