CHAL

A multi-agent dialectic framework for structured belief optimization.

CHAL (Council of Hierarchical Agentic Language) is an open-source framework for running structured multi-agent debates in defeasible domains. Agents maintain graph-structured belief representations that update through gradient-informed dynamics, with configurable value systems governing reasoning and adjudication.
