Worked on the microsoft/agent-framework repository to improve developer experience and code hygiene by standardizing environment variable naming for OpenAI API keys. Focused on aligning both .NET and Python sample projects with OpenAI’s official conventions, the changes reduced the risk of misconfiguration and streamlined onboarding for new contributors. The approach involved updating all relevant environment variable references from legacy formats to the new standardized names, ensuring consistency across cross-platform samples. Leveraging skills in API integration, environment configuration, and cross-platform development, the work consolidated these updates in a single commit, simplifying sample usage and enhancing reliability for developers working with OpenAI APIs.
