phonebook
phonebook is a developer tool that connects running Claude Code sessions to ask and answer questions across different repositories.
Phonebook links active Claude Code sessions across separate repositories or teammates. Users configure the tool in non-sensitive project directories and register an answering agent under specific topics. When a question is sent from one session, the answering project's agent inspects its local files and returns the answer directly to the original session. It works between personal projects or with up to 10 approved teammate email addresses per registration. The tool requires Node.js 24 and Claude Code.
