Developed a ToolChoice-driven tool usage control feature for the Shubhamsaboo/genkit repository, focusing on Google AI and Vertex AI plugin integrations. Leveraging Go for plugin and API integration, the work introduced a mechanism to map ToolChoice settings directly to model configurations, enabling precise governance over tool invocation. Automated tests were added to ensure that ToolChoiceNone reliably prevents models from accessing provided tools, enhancing safety and compliance in plugin operations. This approach improved maintainability and reduced the risk of unintended tool usage across AI plugins, demonstrating a methodical application of Go development and plugin architecture to address policy-driven requirements.
