Worked on upgrading the Simple Math Toolset Example in the google/adk-docs repository to ensure compatibility with the latest version and streamline contributor onboarding. Focused on code refactoring and debugging using Python, the work involved switching to a self-contained runnable example with InMemoryRunner, fixing import paths, and resolving typos and lint issues to meet project standards. These updates improved reliability and maintainability, making local testing more accessible for contributors. By aligning the example with current tooling, the changes reduced the risk of future breakage and simplified ongoing maintenance, supporting faster validation of concepts and demos for project stakeholders.
