Experiments with LLM reviewers attempting to verify AI agent outputs revealed a persistent "75% wall" where valid outputs were rejected. Standard methods like rerunning prompts, using varied prompts, or calibrating wording failed to shift this boundary. The core issue is a fundamental trade-off: a sharper reviewer catches more errors but also rejects more legitimate work, a geometric constraint rather than a model defect. AI
