Agensh: A Decentralized, Scalable Multiagent Harness

About

Agensh is a multi-agent harness in which agents claim sub-tasks, share findings, verify results and merge progress asynchronously without a central orchestrator. It uses Gitea as the shared workspace and Mattermost for messaging. The authors report that on ProgramBench tasks the mean test-pass rate rose from 19.31% with one agent to 28.78% with 128 agents.
