Coordinate with other Claude Code and Codex sessions working on the same project - see who is active and what they are doing, message them, hand off work, and avoid conflicting edits. Use when the user mentions other sessions, agents, Claude, or Codex working in parallel, asks you to coordinate, delegate, hand off, or check in with them, or when <peer-message> blocks arrive.
