New Claude Code feature for cross-session messaging, directly relevant to AI-assisted development workflows.
Summary
Claude Code v2.1.224+ introduces cross-session messaging, allowing one Claude Code session to send text messages to another session automatically or on demand. Claude uses `ListAgents` to discover reachable sessions and `SendMessage` to deliver messages, enabling coordination across parallel worktrees, handoffs of findings, and status updates from long-running tasks. Messages are plain text only—conversation history and files are excluded, and cross-machine replies are supported but sessions cannot initiate exchanges across machines.
