If you’re building an AI-powered UI, you’re much better off using structured JSON output than trying to parse natural language. By baking the exact schema into the system prompt and then strictly validating every field that comes back - like clamping scores or cleaning up labels - you keep the interface stable, even when the model acts a bit differently between runs. The real heavy lifting in prompt engineering wasn't about the "tone" or the "persona"; it was about forcing the output to be structurally predictable without dulling the AI's actual reasoning.
