Worked on enhancing documentation for the pydantic/pydantic-ai repository, focusing on clarifying the behavior of streaming mode with respect to tool calls. The contribution involved technical writing in Markdown, emphasizing clear user guidance and maintainability. By adding explicit warnings and detailed explanations, the documentation now sets accurate expectations that tool calls will not execute in streaming mode unless certain conditions are met. This update addressed user confusion and reduced support queries, while also improving traceability by linking changes to relevant issues. The work demonstrated a disciplined approach to documentation, prioritizing user onboarding and laying a foundation for future streaming-mode improvements.
