loop_engineer

Design, audit, or critique a closed-loop LLM agent — the propose → check → measure → feedback → refine pattern. Use whenever someone wants to add a self-critique / reflection / verifier / best-of-N / debate / self-consistency step, asks whether a refine loop will actually help, wants to optimize or debug a loop that underperforms or overspends, or asks "is this an antipattern." Triggers on phrases like "should I add a critic", "build a feedback loop for my agent", "why isn't my self-refine improving", "audit my agent loop", "best- of-N / self-consistency / reflexion / debate design", "is looping worth it here", or "what's wrong with my agent loop." Entry point is the verifier-edge decision flow; routes to a design guide, an audit checklist, and an antipatterns catalog backed by 28 digested sources.
