+### Endpoint-specific OpenAPI operation transformers
+

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.
+
+For implementation details and code samples, see <xref:fundamentals/openapi/customize-openapi#use-operation-transformers>.
