About

HICO-Bench comprises 180 scenarios across six coordination families where two agents with private information converse to reach a plan. Each scenario has two versions differing in one private condition, requiring distinct correct plans.

Scoring combines rule-based Feasibility (matching records satisfying private conditions) and LLM-judged Integrity. It finds 36% of highly-rated conversations fail verification, with best reported Verified Success at 28.3%.
