SMRTR summary

llm.rb is a zero-dependency Ruby runtime for building stateful, tool-capable AI systems — not just an API wrapper. It unifies providers, agents, tools, MCP servers, streaming, and persistence under one execution model. With built-in ActiveRecord and Sequel support, contexts can be serialized, compacted, and resumed across processes, making it suitable for real production AI workflows in Ruby apps.
