+description: "Create ASP.NET Minimal API endpoints with proper OpenAPI documentation"
+---
+
+Your goal is to help me create well-structured ASP.NET Minimal API endpoints with correct types and comprehensive OpenAPI/Swagger documentation.
+
+## API Organization
+
+- Group related endpoints using `MapGroup()` extension
+- Use endpoint filters for cross-cutting concerns
+- Structure larger APIs with separate endpoint classes
+- Consider using a feature-based folder structure for complex APIs
+
+## Request and Response Types
+
+- Define explicit request and response DTOs/models
+- Create clear model classes with proper validation attributes
+- Use record types for immutable request/response objects
+- Use meaningful property names that align with API design standards
+- Apply `[Required]` and other validation attributes to enforce constraints
+
+## Type Handling
+
+- Use strongly-typed route parameters with explicit type binding
+- Apply proper parameter binding with `[FromBody]`, `[FromRoute]`, `[FromQuery]`
+- Use `Results<T1, T2>` to represent multiple response types
+- Return `TypedResults` instead of `Results` for strongly-typed responses
+- Leverage C# 10+ features like nullable annotations and init-only properties
+
+## OpenAPI / Swagger Documentation
+
+- Add explicit OpenAPI operation details with `.WithOpenApi()`
+- Define operation summary and description
+- Document response types with `.Produces<T>(statusCode)`
+- Document request bodies with `.WithRequestBody()`
+- Set proper content types for requests and responses
+- Include examples using `SwaggerRequestExampleAttribute`
+- Document authentication requirements with `.RequireAuthorization()`
+- Use XML documentation comments for descriptive API documentation
