Score: 7.3/10 (Innovation: 7, Technical: 7, Documentation: 8, Utility: 7)

This project implements a local WebSocket bus enabling peer-to-peer messaging between long-lived Claude Code sessions, allowing one agent to drive another or coordinate across projects. Its innovative combination of agent-to-agent messaging with existing Claude Code sessions, coupled with low-latency delivery via the Monitor tool and support for iterative workflows, makes it a unique tool for advanced multi-agent coordination in development workflows.

Target audience: backend devs, devops
