Worked on enhancing the public API surface of the openai/openai-agents-js repository by exposing the ToolOptions type in the @openai/agents-core exports. This change focused on improving developer experience and integration workflows by strengthening type-safety and clarifying API contracts. The work was implemented using TypeScript, with an emphasis on robust API design to support future tool integration. By making ToolOptions accessible, the update facilitated easier adoption for developers leveraging the agents-core public API and aligned the repository with upcoming tooling enhancements. The contribution addressed a key integration need and laid groundwork for more extensible and maintainable TypeScript-based APIs.
