Worked on the 0xPlaygrounds/rig repository to integrate provider-native hosted tools into the completion system, enabling seamless execution of tools such as web_search and file_search within completion requests. Developed new API structures in Rust to define these tools and methods for adding them to CompletionRequest, enhancing the system’s extensibility for future integrations. Updated documentation to reflect these changes and ensured test coverage for hosted tool integration. Focused on backend development, the work addressed the need for more flexible and scalable tooling within the platform, laying the groundwork for further expansion of provider-native capabilities in the completion workflow.
