Prompt Improvement Log

AI / GenAI Documentation

Before/after prompt pairs showing iterative improvement of AI prompts.

Iteration 1: Unstructured to Structured Output

	Prompt	Problem/Improvement
Before	You are a pregnancy assistant. Help the user with their symptom.	Returned long, unparseable text responses
After	Respond in JSON only: { "empathetic_response": "...", "doctor_summary": "..." }	Structured, parseable output every time

Iteration 2: Response Length Control

	Prompt	Problem/Improvement
Before	Provide a supportive response and doctor summary	Responses were 200-500 words, too long for mobile display
After	Brief supportive message (max 50 words), comfort measures (max 20 words)	Concise responses suitable for mobile UI

Iteration 3: Pregnancy Context Injection

	Prompt	Problem/Improvement
Before	Translate this message to Korean: {message}	Generic translation without medical context
After	Translate pregnancy-related message to Korean. Context: week {week}. Message: {message}	Medically aware translation with trimester context

Iteration 4: Safety Truncation

Added server-side safety: empathetic responses capped at 300 characters, comfort measures at 120 characters. Input text truncated to 100 characters for translation calls. This prevents prompt injection via long inputs and ensures consistent UI rendering.
