Socrates
A multi-agent protocol from Hexo Labs that pairs a tool-using AI Scientist with a question-only advisor (Socrates). The advisor can never give answers, issue directives, or use tools — it can only ask clarifying questions and must approve every experiment plan via an [APPROVED] gate before execution. Published at COLM 2026, the protocol improves Kaggle test scores by +55.9% on average across five MLE-bench tasks compared to the same agent running solo.
