Anthropic's Claude Code has introduced an experimental feature called Cross-session messaging, allowing multiple running sessions to communicate directly. This enables sessions focused on different tasks, such as database management, API development, and testing, to exchange information and coordinate actions without direct developer intervention. The system ensures that only relevant task results and dependency information are shared, maintaining session isolation and preventing the overwhelming of one session with another's full context. This feature integrates into Claude Code's agentic loop as an asynchronous input source, allowing for more sophisticated agent collaboration and external process integration. AI
