 ### Endpoint-specific OpenAPI operation transformers
 
-OpenAPI [operation transformers](<xref:fundamentals/openapi/customize-openapi#use-operation-transformers>) can now be registered directly on individual endpoints using the `AddOpenApiOperationTransformer` extension method. This allows customization of OpenAPI metadata to be colocated with the endpoint definition, rather than requiring global configuration with path-based conditional logic.
+Endpoint-specific operation transformers enable fine-grained customization of OpenAPI documentation for individual route endpoints. This feature allows developers to tailor Swagger/OpenAPI metadata and descriptions on a per-action or per-route basis, enhancing extensibility for advanced API scenarios.
 
-Prior to this feature, modifying OpenAPI data for specific endpoints required registering a global operation transformer and implementing conditional logic to target specific endpoints. For example:
-
-```csharp
-builder.Services.AddOpenApi(options =>
-{
-    options.AddOperationTransformer((operation, context, ct) =>
-    {
-        if (context.Description.RelativePath == "deprecated-endpoint")
-        {
-            operation.Deprecated = true;
-        }
-
-        return Task.CompletedTask;
-    });
-});
-```
-
-With the new `AddOpenApiOperationTransformer` API, the same customization can be applied directly to the endpoint, with access to the full operation context as well:
-
-```csharp
-app.MapGet("/deprecated-endpoint", () => "This endpoint is old and should not be used anymore")
-.AddOpenApiOperationTransformer((operation, context, cancellationToken) =>
-{
-    operation.Deprecated = true;
-
-    return Task.CompletedTask;
-});
-```
-
-This approach improves code readability and maintainability by keeping endpoint-specific customizations close to the endpoint definitions. The `AddOpenApiOperationTransformer` method provides access to the full <xref:Microsoft.AspNetCore.OpenApi.OpenApiOperationTransformerContext>, enabling comprehensive customization of the OpenAPI operation, including:
-
-* Setting operation properties like `Deprecated`, `Summary`, or `Description`
-* Customizing response descriptions
-* Adding or modifying security requirements
-* Modifying parameters or request bodies
