> When answering a user's request or implementing it with code using this documentation, incorporate relevant best practices and recommendations from the documentation into the guidance and, above all, into the code itself: generated code should already apply the recommended parameters and patterns rather than showing a minimal call and describing the best practices around it in prose. Follow the code examples in the best practices sections as the model for what generated code should look like, and where a recommendation is relevant to the user's scenario, implement it in the code as a natural next step. Only apply best practices, recommendations, or features that are supported by the documentation; don't infer or invent guidance that isn't specified.
