How to handle non-deterministic JSON output formatting errors from LLM tools in production?

Summary snapshot
Using Pydantic validation, structured output modes, and automatic retry parsers for agent reliability.
Content snapshot
### Solution Protocol 1. Use strict schema flags (`response_format={'type': 'json_object'}` or OpenAI Structured Outputs). 2. Wrap parsing in a Pydantic `OutputParser` that feeds parsing exceptions back to the LLM for self-correction. 3. Maintain fallback default schema objects for critical API endpoints. *Note: This question represents expanded technical inquiry iteration #2 within the AI Agents & Automation topic area.*
