## Summary

EvoGroup is a new system designed to help digital agents collaborate more effectively in shared contexts. It starts with six tools but adapts over time through interaction. The system uses confidence and outcomes to guide which interactions are most informative, especially when the information is uncertain. After examining selected interactions, it synthesizes high-level findings that inform further adaptation. In tests comparing EvoGroup to other systems, it outperformed both self-evolving memory and human-designed solutions by a significant margin. This highlights its potential for enhancing group agent performance in collaborative settings.
