DSPy Output Refinement & Constraints

Goal

Improve output quality using iterative refinement (dspy.Refine) and best-of-N selection (dspy.BestOfN) with custom constraint validation.

When to Use

• Outputs need format validation (JSON, specific structure)
• Length constraints (max tokens, word count)
• Content requirements (must include X, avoid Y)
• Quality improvement through multiple attempts
• Replacing deprecated Assert/Suggest patterns
