Claude Code Adds Cross-Session Messaging Feature

Posts quote a ClaudeDevs announcement that Anthropic added inter-session messaging to Claude Code. One session can now send a concise task summary to another so the receiving session resumes work without manual re-explanation of prior steps. Users including Seth Lazar, Judd Rosenblatt, Danielle Fong, and Xing Han Lu shared reactions to the change. One post notes the feature resembles an earlier open-source agent-talk project. Visible replies treat the update as removing the need for separate handoff tools.
