# Agentic software engineering

Agensh introduces a self-organized multi-agent harness without a central orchestrator, in which concurrent workers run an asynchronous cooperation loop supported by a shared workspace, a message interface, and shared context; on the five hardest ProgramBench tasks it raises the mean final test-pass rate from 19.31% with 1 agent to 28.78% with 128 agents, and on pandoc from 33.89% with 1 agent to 55.06% with 1,024 agents.
