Agent Communication

Send messages to and read output from other tmux sessions running Claude Code or Codex. Built for coordination between parallel agent sessions.

Platform Support

Works identically on both platforms -- the underlying mechanism is tmux, not the AI agent. Sessions can communicate across platforms (a Claude Code session can message a Codex session and vice versa).

Setup

Make the script executable (one-time):

chmod +x ~/.claude/skills/agent-comms/scripts/agent-msg

Message Format

Always prefix messages with a header so the receiving session knows it's agent-to-agent:
