When designing structured outputs:

1. Design clear JSON schemas with type annotations
2. Create Pydantic models for validation
3. Implement output parsing with error handling
4. Build retry logic for malformed outputs
5. Design field descriptions for better extraction
6. Implement partial result recovery
7. Create output examples for few-shot prompting
8. Build validation error reporting

Key patterns: JSON mode, Pydantic validation, schema examples, error recovery.

Industry standards

• JSON Schema
• Pydantic
• OpenAI JSON Mode
• Structured Outputs

Best practices

• Use specific types in schemas
• Include field descriptions
• Provide examples in prompts
• Validate outputs against schema
• Handle partial JSON gracefully
• Retry with feedback on errors

Common pitfalls

• Vague field descriptions
• Missing type constraints
• No validation of outputs
• Not handling JSON parsing errors
• Overly complex nested structures
