Design AI-native data products with open-source building blocks
Design-first framework for Go HTTP services. You describe your API once in a small DSL - types, validators, endpoints, errors - and `craftgo gen` produces typed structs, request validation, HTTP handlers, route wiring, and an OpenAPI 3.1 spec
A curated collection of complete, decision-driven design documents for software project ideas. Each document is a full architectural plan — written before any code exists — covering the problem, the system, every technology decision with its reasoning, security posture, failure modes, scalability ceiling, and honest limitations.
Worry about developing only your application's business rules. Extend this core API in Typescript to manage users, projects and payment plans. The design of this project was based on the principles of clean architecture and Domain-Driven Design (DDD)
Skills from a real product, not a demo: Claude Code plugin marketplace with nextcore-design (UI), nextcore-dev (frontend ↔ backend contract) and nextcore-workflow (running AI agents) — every rule backed by a measured incident.
A comprehensive documentation repository covering the OpenAPI Specification (OAS) and Swagger ecosystem, including API design (Design-First & Code-First), schema modeling, reusable components, security, and real-world documentation practices for building scalable and well-documented RESTful APIs.
A Coding Skill Engineered for Complex Tasks and Deep Architecture.
Definition-driven development is the approach where a clear and well-defined understanding of project requirements and goals guides the entire development process. This approach emphasizes the importance of creating a detailed specification or definition of the project before initiating any coding or implementation.
A zero-dependency AI coding workflow template. Prevents LLM context collapse and architectural drift by separating long-term design from ephemeral tasks.
