FAQ
How do you guarantee valid JSON output formats?
I enforce strict Pydantic schemas, integrate few-shot exemplars, and embed programmatic syntax validation constraints directly into the system prompts to block raw text conversational filler.
Can you handle complex nested JSON architectures?
Yes. I build advanced hierarchical token rules and structural placeholders that force the LLM to output deep nested objects without breaking your software backend pipelines.
How do you prevent RAG hallucinations in JSON?
I inject strict context boundary rules. If the vector database lack relevant data, the prompt forces the agent to safely return a clean null JSON object.
Are your prompts optimized for Claude and OpenAI?
Yes. I engineer and benchmark separate versions tailored specifically to the unique prompt engineering guidelines, token efficiencies, and XML/system tag preferences of Claude and OpenAI.
Do you protect against prompt injection attacks?
Yes. I integrate defensive system prompt layers and jailbreak guardrails designed to prevent external user inputs from overriding the core JSON structural logic and agent rules.
