I’ve been leaning hard into Sorbet runtime types for DSPy.rb[0] and finding real value. T::Struct at API boundaries, typed props for config, runtime validation where data enters the system.

For generating (with LLMs) API clients and CLIs it’s especially useful—define the shape once, get validation at ingress/egress for free.

Maybe momentum is happening in new projects rather than retrofits? [0] https://oss.vicente.services/dspy.rb
