How DSLs Enable Reliable Use of LLMs in Software Development

DSLs Enable Reliable Use of LLMs

I argue that Domain-Specific Languages make Large Language Models far more reliable by constraining the output space. While upfront specifications are often just hypotheses, DSLs provide a clear vocabulary and deterministic validators. This allows LLMs to act as effective co-designers and precise interfaces, turning natural language into valid code or configurations that can be automatically checked and repaired without human intervention.

"A specification is at best a starting hypothesis: the real constraints, trade-offs, and edge cases are discovered iteratively, as we proceed with the implementation."
