Stop AI Agent Hallucinations With Code, Not Prompts

Your AI agent books 15 guests despite a 10-person maximum. Another fabricates occupancy rates the database never had. A third picks the wrong tool from 29 and burns tokens.

This hands-on workshop walks through 5 techniques to stop these failures: Graph-RAG for grounded retrieval, semantic tool selection, multi-agent validation, neurosymbolic guardrails, and steering. You'll see live demos, then take the patterns to production.
