SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill streamlines the process of reviewing and validating API Data Transfer Object implementations to ensure proper separation, mapping, and REST compliance.

Core Features & Use Cases

DTO Structure Validation: Checks that request and response DTOs follow naming and attribute conventions.
Mapping Pattern Verification: Ensures controller methods use private static mapping helpers and avoid external mapping libraries.
REST and Validation Checks: Validates route parameter placements, model state checks, error handling, and response types for API endpoints.

Quick Start

Use the review skill to analyze your API project and identify gaps in DTO structure, mapping, and REST adherence.

FAQPage Schema

How do I validate API DTO structure and enforce contract separation in my controllers?▼

To validate API DTO structure, ensure request and response models follow naming conventions and maintain strict contract separation. Verify that controller actions use private static mapping helpers instead of external libraries to isolate domain models from API contracts.

What is the best way to ensure REST standards compliance across API endpoints?▼

The best way to ensure REST compliance is to systematically check route parameter placements, model state validations, and error handling within API endpoints. Consistent response types across controller actions guarantee reliable integration and standardized data transfer.

Why should I use private static mapping helpers instead of external mapping libraries for DTOs?▼

Using private static mapping helpers for DTOs prevents external library dependencies from leaking into controller logic, ensuring proper separation. This pattern keeps API data transfer implementations robust, consistent, and easier to review for contract adherence.

How do I check if my API request and response models follow proper naming conventions?▼

To check if API request and response models follow naming conventions, review your DTO structure to validate attribute usage and naming patterns. This ensures consistent data transfer object implementations across all controller actions and endpoints.

Does my API project need consistent response types for reliable endpoint integration?▼

Yes, your API project needs consistent response types for reliable endpoint integration. Validating response consistency alongside proper error handling and model state checks ensures clients can consume REST endpoints predictably and safely.

When do I need to validate route parameter placements in REST API controllers?▼

You need to validate route parameter placements in REST API controllers when reviewing endpoint definitions for REST adherence. Correct parameter placement ensures proper routing, validates model state, and supports consistent error handling across API actions.
