Validation, Docs, tests, and database schemas from one source of truth

Triad is a TypeScript-first API framework that generates validation, OpenAPI/AsyncAPI documentation, BDD tests, and database schemas from a single source of truth, eliminating the need for separate configuration files and preventing specification drift. The framework integrates with Claude Code to enable AI-assisted API scaffolding and development through a marketplace plugin with pre-built skills and slash commands. By consolidating all API artifacts into one typed definition, Triad keeps both human developers and AI assistants productive by providing a single place to understand and reason about an entire API.
