Plugin Enables Cross-Session Messaging Between Parallel Claude Code Instances

r/ClaudeAI·high signal

Developer built a plugin so parallel Claude Code sessions (e.g., frontend and backend repos) can message each other directly instead of requiring manual alt-tabbing to relay information. Eliminates the pattern of asking 'wait, what shape did the user object end up as?' by enabling sessions to query each other's context in real-time. 97 upvotes on r/ClaudeAI.
