Worked on the pydantic-ai repository to enhance documentation, focusing on clarifying how built-in and user tools interact with the Google AI platform. The update addressed a common source of confusion by specifying that these tools cannot be used simultaneously with Google, and introduced a structured-output approach to guide correct implementation. Using Markdown and leveraging strong documentation skills, the work aimed to improve onboarding for developers and reduce support overhead. No bugs were fixed during this period, but the documentation changes provided clearer usage guidance for integrating external AI services, contributing to a more robust and maintainable developer experience overall.
