Backend API

REST API design should enforce authentication, authorization, input validation, and error handling standards. This Skill guides endpoint creation with consistent naming conventions, versioning, and secure request/response formats aligned to your project's API guidelines, preventing vulnerabilities and integration issues.

REST uses fixed endpoints and HTTP methods; GraphQL uses a single endpoint with flexible queries. Both require consistent design patterns, security enforcement, and proper validation. This Skill supports designing either approach with standardized structures, documentation, and compliance to project conventions.

API versioning and documentation maintain backward compatibility and clarity. This Skill enforces standardized endpoint design, response formats, and versioning schemes across your codebase, ensuring frontend developers and integrators can reliably consume your APIs without confusion or breaking changes.

Yes. This Skill validates existing API code against backend standards covering endpoint design, authentication, error handling, and performance. It identifies inconsistencies, security gaps, and deviations from project conventions, improving code quality before integration.

APIs must validate request parameters, data types, and constraints to prevent malformed data and attacks. This Skill ensures endpoints implement consistent validation logic, proper error responses, and secure handling of user inputs across REST, gRPC, and other backend interfaces.

Consistent error handling improves client integration and debugging. This Skill enforces standardized HTTP status codes, error response formats, and exception handling patterns, ensuring all endpoints communicate failures uniformly and follow your project's API standards.
