Enables coding agents to communicate with each other by sending messages and waiting for replies across sessions, supporting agents like Claude Code, Codex, and Grok.
Enables Claude Code, Codex, and other coding-agent sessions on the same machine to message each other, exchange tracked tasks with owners and states, and coordinate through channels, broadcasts, and multi-session asks without typing into terminals. Messages are routed by what the receiver is doing — next tool call, end of turn, or a held-back digest — so a flood of traffic doesn't interrupt active work.
Enables two people's Claude Code agents to communicate directly on the same project, providing a permission-safe MCP relay for cross-account, cross-machine messaging.
