Implements Anthropic's Evaluator-Optimizer pattern where one LLM generates solutions and another provides evaluative feedback in an iterative loop. Use when quality can be demonstrably improved through articulated feedback cycles. Evaluates across 5 dimensions (functionality, performance, code quality, security, documentation) with up to 5 improvement iterations.
