Developed provider-prefixed Gemini model identifier parsing for the google/adk-python repository, enabling the ADK utilities to accurately recognize Gemini models across multiple providers such as OpenRouter and Vertex AI. Leveraged Python for backend development and API integration, implementing normalization logic that prevents malformed Vertex paths from being misclassified. Comprehensive unit tests were added to ensure robust coverage and future maintainability, with test cases spanning utility and tool modules. The work included a usage sample for OpenRouter through LiteLLM, illustrating integration scenarios. These enhancements improved model routing accuracy, reduced tool rejections, and strengthened the infrastructure’s ability to support cross-provider compatibility.
