Show HN: Phonebook lets one Claude Code session ask another repo's agent a question
Phonebook (npx [email protected] setup) connects running Claude Code sessions, so an agent in one project can ask a session you've registered in another repo (yours or an approved teammate's) and get the answer back where you're working; it needs Node.js 24 and runs on macOS or Linux, not Windows. Sign-up is paused for now, and questions and replies pass through Phonebook without end-to-end encryption and are kept for up to 7 days, so stick to non-sensitive projects.
