概要
This skill elevates Claude Code from an interactive tool to a self-directing development agent by establishing a collaborative feedback loop between two Claude instances. Using a Stop hook architecture, an external Opus 4.5 analyzer reviews work against your defined success criteria after every iteration, deciding whether to continue with specific next-step instructions or terminate upon completion. It is specifically designed for complex, multi-step engineering tasks—such as overnight feature builds or deep codebase refactoring—while maintaining safety through robust cost tracking, iteration limits, and automated doom-loop prevention.
