ArchSpec 1.0: Executable Architecture Specification for Ruby’s Agent Coding Era

More and more code is written by a model. Tests still tell you it works. RuboCop still tells you it’s tidy. Nothing tells you it still follows your architecture. I released ArchSpec 1.0 today. It’s an architecture linter for Ruby and Rails. You declare your components and boundaries in one file, and every change gets checked, whether a person or an agent wrote it. This is part of my push towards making Ruby one of the best languages to build with AI. RubyLLM is one piece. Schematist is another. Making the default Rails job queue fiber-based is another.
