REST API endpoint generation automates scaffold creation with request validation, error handling, and route mapping. This Skill produces production-ready route handlers for Express, Fastify, or NestJS with body, parameter, and query validation built in, plus error responses and middleware integration.

GraphQL endpoint generation creates resolvers with validation and test suites alongside route handlers. The Skill produces schema-aligned endpoints with proper error handling and accompanying test files for both REST and GraphQL setups.

API endpoint generation supports Express, Fastify, NestJS, and GraphQL frameworks. The Skill adapts scaffold structure, middleware patterns, and validation syntax to each framework's conventions while maintaining consistent request validation and error handling.

Authentication middleware integration applies to generated route handlers during scaffold creation. The Skill embeds middleware configuration alongside request validation and error handlers, allowing tokens and credentials to be validated before business logic executes.

Test suite generation creates test files alongside endpoint scaffolds with validation and error-case coverage. Tests verify route handlers, parameter validation, error responses, and middleware execution to ensure functional and technical requirements are met.

Endpoint validation covers request body, URL parameters, and query string validation with schema enforcement. The Skill applies proper HTTP method mapping, type checking, and error responses for invalid inputs across REST and GraphQL endpoints.
