The Schema IS the Prompt: Rethinking AI-Native Software Design

Short summary

Instead of prompt-centric design (prompt → LLM → parse → validate), move to schema-centric design where the data model is the source of truth. The author shows how exomodel enables this in Python, analogous to how ORMs replaced raw SQL strings. This pattern reduces prompt fragmentation, improves validation, and simplifies provider switching.

• •Schema-centric design inverts traditional LLM application patterns by making the data model the source of truth
• •exomodel (Python library) implements this, similar to how ORMs abstracted database interaction
• •Benefits: reduced prompt fragmentation, automatic validation, simpler provider switching
