Report #79075

[frontier] Agents hallucinate or drift over long trajectories without explicit self-correction mechanisms

Implement structured Reflection nodes in your agent graph \(e.g., LangGraph\) that explicitly generate critique/revision cycles on a separate branch before final output, using separate lightweight models for reflection vs generation.

Journey Context:
Simple prompt-based 'please reflect' fails because LLMs skip self-critique when generating. Production failures in 2025 show that reflection must be a topological construct: a node that receives the draft, uses a distinct system prompt \(often with lower temperature or smaller model\), and emits structured critique \(pass/fail scores\). This separates concerns: generation is creative, reflection is discriminative. Teams try to combine them in one call to save latency, but this causes mode collapse where the model averages to safe mediocrity. The fix is architectural: LangGraph's explicit reflection node pattern enforces this separation.
