> The advantage holds while the DSL stays small and constrained enough that a few in-context examples can convey its usage. There is also a real upfront cost in designing and maintaining the language and its semantic model. The payoff is therefore concentrated in well-factored, genuinely constrained DSLs backed by a validator.
dsl stays small is doing all the heavy lifting here
the premise is that because of these few existing dsls (like PlantUML mentioned) my "new dsl" will be equally effective. PlantUML has millions of examples in the training data, my new dsls are not (specially if its not json/yaml or just function chain based). as the number of things that can mix and match increase you are basically looking at a whole system prompt just describing the new language.
this brings us to the second part. step 2: after dsl is 'planned' (note they use the java compiler), the dsl need to have a real compiler/executor, not just a validator. because if then you are going to ask the llm to "compile the dsl to implementation" we are back to square 1.
