Report #54349

[architecture] Agent chain hallucinates confidently or loops infinitely on edge cases without human intervention

Implement quantitative confidence scoring or deterministic validation checks at agent handoffs. If confidence < threshold or validation fails, route to a human-in-the-loop \(HITL\) queue instead of the next agent.

Journey Context:
Agents are bad at knowing what they don't know. Passing low-confidence outputs down the chain creates 'error snowballs' where subsequent agents base reasoning on flawed premises. People try to fix this by adding 'be careful' to prompts. The right call is programmatic: enforce a hard threshold on confidence or validation scores, treating the HITL as just another node in the graph.
