Report #39964
[architecture] Single-agent verification fails for critical outputs due to inability to catch its own hallucinations
Implement redundant execution consensus: two independent agent instances generate outputs; a third 'judge' agent \(or deterministic AST diff for code\) verifies semantic equivalence; on disagreement, escalate to human
Journey Context:
Asking an agent to 'check your work' is ineffective due to inherent bias and consistent error patterns. Independent generation \(different temperatures or models\) reduces correlated failures. For code, Abstract Syntax Tree \(AST\) comparison detects semantically equivalent but syntactically different outputs. For text, an LLM-as-judge with a structured rubric evaluates consistency. This is triple modular redundancy for software agents, critical for medical or legal domains. Tradeoff: 3x token cost and latency versus reliability and correctness guarantees.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
