Does it automatically create unit tests?

Yes, it generates a comprehensive test file including cases for success (200/201), validation errors (400), unauthorized access (401), and server errors (500).

Can I customize the validation library used?

Yes, it supports Zod, Joi, Yup, and Express-validator. It typically detects which library you are already using in your project.

What is the 'ToM Checkpoint' mentioned in the execution steps?

Theory of Mind (ToM) is a verification step where Claude confirms its interpretation of your requirements and architectural assumptions before writing code to ensure accuracy.

Which frameworks does the Backend Endpoint skill support?

It supports Express (default), Fastify, NestJS, and GraphQL resolvers, adapting to the framework detected in your package.json.

API開発

Generates production-ready REST and GraphQL endpoints with built-in validation, error handling, and comprehensive test suites.

概要

The Backend API Endpoint Generator is a specialized skill for Claude Code designed to accelerate backend development by scaffolding robust, standardized API routes. It automates the boilerplate associated with route definition, request validation (supporting Zod, Joi, and Yup), centralized error handling, and integration testing. By incorporating a Theory of Mind (ToM) verification step, the skill ensures that generated code aligns with your project's existing architectural patterns and framework preferences, such as Express, Fastify, or NestJS.
